Calculated fields in SKD. Data Composition System Expression Language (1Cv8)

Hello, dear reader! We have another lesson on the basics of the layout system. In you got acquainted with the functions of the SKD expression language, saw the features of the layout system, and also understood the basic settings of the layout fields. Now we will look at new material. Go!

Additional settings for ACS fields.

Column "Value Type" Allows you to specify the data type for the layout field. Why specify the type, for example, for the “Nomenclature” field, if you already know what type it is? This is necessary if the layout field is of a composite type. You can select a specific type, then when selecting by this field, values of this type will be selected.

Column "Available values" allows you to specify the values available for selection and limit the user’s choice to certain limits.

Column "Decor" allows you to specify the design of a layout field without using layouts. You can specify the font color, frame color, text orientation, etc.

Column "Editing Options" Allows you to specify how to edit the layout field. For example, you can specify a quick selection of elements from a list in a selection. By default, a layout field inherits all editing options from the metadata object.

Calculated fields

On the “Calculated Fields” tab of the data composition, you can create your own calculated fields.

Why do you need calculated fields when you can create them at the query level? Not all fields can be described using a query. If you need to create a complex field from different sets of data, for example, such as a query and an object, then you cannot do without calculated fields. You cannot add a data composition field if the data source is a query and autofill is enabled, but using calculated fields you can add as many fields as you like.

In the “Expression” column of the calculated field, you need to write an arbitrary expression that uses the data composition fields, accessing their path (the “Path” column on the “Data Sets” tab). Either you can use mathematical transformation functions or access the functions of common modules. For example, let’s write in the “Data Path” column the name of the calculated field “Deviation”, and in the “Expression” field the following.

In light of the upcoming release of 8.2.14, I will try to describe some new functions of the data composition system.

Open the data layout diagram, preferably in an external report, to make editing easier.

We add a dataset of the query type and write, either manually or using the query designer, a simple query:

1. Set up a request in the access control system.

2. Set up calculated fields in the access control system

3. Configure the data layout on the settings tab

4. Launch 1C Enterprise 8.2.14. Open the report. We form, we receive.

Description of the new functions themselves:

1. The current date()

Returns the system date. When composing a layout layout, in all expressions that are present in the layout, the CurrentDate() function is replaced with the value of the current date.

2. COMPUTEEXPRESSION()

Syntax:

CalculateExpression(,)

Description:

The function is designed to evaluate an expression in the context of some grouping.

The function takes into account the selection of groupings, but does not take into account hierarchical selections.

The function cannot be applied to a grouping in the group selection of that grouping. For example, in selecting the Nomenclature grouping, you cannot use the expression CalculateExpression("Sum(SumTurnover)", "TotalTotal") > 1000. But such an expression can be used in hierarchical selection.

If the end record precedes the start record, then it is considered that there are no records for calculating detailed data and calculating aggregate functions.

When calculating interval expressions for a grand total (the Grouping parameter is set to GrandTotal), it is assumed that there are no records for calculating detailed data and calculating aggregate functions.

Layout linker when generating a function expression CalculateExpression, if the ordering expression contains fields that cannot be used in grouping, replaces the function CalculateExpression on NULL.

Options

Type: Line. The expression to be evaluated.

Type: Line. Contains the name of the grouping in the context of which the expression is to be evaluated. If an empty string is used as the grouping name, the calculation will be performed in the context of the current grouping. If the GeneralTotal string is used as the group name, the calculation will be performed in the context of the grand total. Otherwise, the calculation will be performed in the context of the parent grouping with the same name.

For example:

Sum(Sales.SumTurnover)/Calculate("Sum(Sales.SumTurnover)", "Total")

In this example, the result will be the ratio of the sum by field Sales.AmountTurnover grouping records to the sum of the same field in the entire layout;

Type: Line. The parameter can take the following values:

· Grand total— the expression will be calculated for all grouping records.

· Hierarchy— the expression will be evaluated for the parent hierarchical record, if there is one, and for the entire grouping, if there is no parent hierarchical record.

· Grouping— the expression will be evaluated for the current group grouping record.

· GroupingNonResource— when calculating a function for a group record by resources, the expression will be calculated for the first group record of the original grouping.

When calculating a function CalculateExpression() with meaning GroupingNonResource for group records that are not grouped by resources, the function is calculated in the same way as it would be calculated if the parameter value was equal to the value Grouping.

The data composition layout builder, when generating a data composition layout when outputting a resource field by which grouping is performed to the layout, places an expression in the layout that is calculated using the function CalculateExpression() , indicating the parameter GroupingNonResource. For other resources, the usual resource expressions are placed in the resource grouping.

Type: Line. Indicates from which record the fragment should begin, in which aggregate expression functions should be calculated, and from which record to obtain field values outside of aggregate functions. The value can be one of the following:

· First

· Last (Last)

· Previous

· Next (Next)

· Current

· LimitingValue(BoundaryValue) LimitingValue

Type: Line. Indicates to which record the fragment should be continued, in which the aggregate functions of the expression should be calculated. The value can be one of the following:

· First. It is necessary to obtain the first grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the beginning of the grouping. The resulting value must be an integer greater than zero. For example, First(3) - receiving the third record from the beginning of the grouping.

If the first record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get First(4), then it is considered that there are no records.

· Last (Last). You need to get the last grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the end of the grouping. The resulting value must be an integer greater than zero. For example, Last(3) - receiving the third record from the end of the group.

If the last record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get Last(4), then it is considered that there are no records.

· Previous. You need to get the previous grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset back from the current grouping record. For example, Previous(2) - getting the previous from the previous record.

If the previous record goes beyond the grouping (for example, for the second grouping record you need to get Previous(3)), then the first grouping record is obtained.

When retrieving the previous record for a grouping total, it is considered that the first record is obtained.

· Next (Next). You need to get the next grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset forward from the current grouping entry. For example, Next(2) - getting next from the next record.

If the next record goes beyond the grouping, then it is considered that there are no records. For example, if there are 3 entries and the third entry receives Next() , then it is considered that there are no entries.

When the next record is received for the grouping total, it is considered that there is no record.

· Current. You need to get the current record.

When retrieving for a grouping total, the first record is obtained.

· LimitingValue(BoundaryValue). The need to get a record by the specified value. After the word LimitingValue in brackets you need to indicate the expression with the value of which you want to start the fragment, the first ordering field.

The first record whose ordering field value is greater than or equal to the specified value will be returned as the record. For example, if the Period field is used as the ordering field, and it has the values 01/01/2010, 02/01/2010, 03/01/2010, and you want to get LimitingValue(DateTime(2010, 1, 15)), then a record with the date 02/01/2010 will be received.

Type: Line. Lists expressions, separated by commas, that describe the ordering rules. If not specified, then the ordering is performed in the same way as for the grouping for which the expression is evaluated. After each expression you can specify a keyword Age(for ordering in ascending order), Descending(for ordering in descending order) and Auto-order(to order reference fields by the fields by which you want to order the referenced object). Word Auto-order can be used as with the word Age, so with the word Descending.

Type: Line. Same as parameter Sorting. Used to organize hierarchical records. If not specified, the layout builder generates the ordering according to the ordering specified in the parameter Sorting.

Type: Line. Specifies the rule for determining the previous or next record in case there are several records with the same ordering value:

· Separately indicates that a sequence of ordered records is used to determine the previous and next records. Default value.

· Together indicates that the previous and next records are determined based on the values of the ordering expressions.

For example, if the resulting sequence is ordered by date:

№	date	Full name	Meaning
1	January 01, 2001	Ivanov M.	10
2	02 January 2001	Petrov S.	20
3	January 03, 2001	Sidorov R.	30
4	04 January 2001	Petrov S.	40

Separately, That:

§ the previous entry to entry 3 will be entry 2.

Current, Current(accordingly, parameters Start And End), then for record 2 this fragment will consist of one record 2. The expression will be equal to 20.

If the parameter value is Together, That:

§ the previous entry to entry 3 will be entry 1.

§ if the calculation fragment is defined as Current, Current(accordingly, parameters Start And End), then for record 2 this fragment will consist of records 2 and 3. Expression CalculateExpression("Sum(Value)", Current, Current) will be equal to 50.

When specifying a parameter value equal to Together, in parameters Start And End you cannot specify an offset for positions First, Last, Previous, Next.

CalculateExpression("Sum(SumTurnover)", "First", "Current")

If you want to get the grouping value in the previous line, you can use the following expression:

CalculateExpression("Rate", "Previous")

List new functions:

CalculateExpressionWithGroupArray(,) -

The function returns an array, each element of which contains the result of evaluating an expression for grouping by the specified field.

CalculateExpressionWithGroupValueTable(,) -

The function returns a table of values, each row of which contains the result of evaluating expressions for grouping by the specified field

ValueFilled() - Returns True if the value is other than the default value of this type, other than NULL, other than an empty reference, other than Undefined. Boolean values are checked for NULL values. Strings are checked for the absence of non-whitespace characters

Format(, ) - Receive a formatted string of the passed value. The format string is set in accordance with the format string of the 1C:Enterprise system.

Substring(, , ) - This function is designed to extract a substring from a string.

Line Length() - The function is designed to determine the length of a string. Parameter is a string expression

Line() - If an array is passed as a parameter, the function returns a string containing string representations of all array elements, separated by "; " characters. If a table of values is passed as a parameter, the function returns a string containing string representations of all rows of the table of values, with the cell representations of each row separated by ";" characters, and the rows by a newline character. If an element's string representation is empty, then a string is displayed instead of its representation.

In light of the upcoming release of 8.2.14, I will try to describe some new functions of the data composition system.

Open the data layout diagram, preferably in an external report, to make editing easier.

We add a dataset of the query type and write, either manually or using the query designer, a simple query:

Description of the new functions themselves:

1. The current date()

Returns the system date. When composing a layout layout, in all expressions that are present in the layout, the CurrentDate() function is replaced with the value of the current date.

2. COMPUTEEXPRESSION()

CalculateExpression(,)

Description:

The function is designed to evaluate an expression in the context of some grouping.

The function takes into account the selection of groupings, but does not take into account hierarchical selections.

If the end record precedes the start record, then it is considered that there are no records for calculating detailed data and calculating aggregate functions.

Options

Type: Line. The expression to be evaluated.

For example:

Sum(Sales.SumTurnover)/Calculate("Sum(Sales.SumTurnover)", "Total")

In this example, the result will be the ratio of the sum by field Sales.AmountTurnover grouping records to the sum of the same field in the entire layout;

Type: Line. The parameter can take the following values:

· Grand total— the expression will be calculated for all grouping records.

· Hierarchy— the expression will be evaluated for the parent hierarchical record, if there is one, and for the entire grouping, if there is no parent hierarchical record.

Type: Line. Indicates to which record the fragment should be continued, in which the aggregate functions of the expression should be calculated. The value can be one of the following:

If the previous record goes beyond the grouping (for example, for the second grouping record you need to get Previous(3)), then the first grouping record is obtained.

When retrieving the previous record for a grouping total, it is considered that the first record is obtained.

When the next record is received for the grouping total, it is considered that there is no record.

If the parameter value is Together, That:

§ the previous entry to entry 3 will be entry 1.

When specifying a parameter value equal to Together, in parameters Start And End you cannot specify an offset for positions First, Last, Previous, Next.

CalculateExpression("Sum(SumTurnover)", "First", "Current")

If you want to get the grouping value in the previous line, you can use the following expression:

CalculateExpression("Rate", "Previous")

List new functions:

CalculateExpressionWithGroupArray(,) -

The function returns an array, each element of which contains the result of evaluating an expression for grouping by the specified field.

CalculateExpressionWithGroupValueTable(,) -

The function returns a table of values, each row of which contains the result of evaluating expressions for grouping by the specified field

Format(, ) - Receive a formatted string of the passed value. The format string is set in accordance with the format string of the 1C:Enterprise system.

Substring(, , ) - This function is designed to extract a substring from a string.

Line Length() - The function is designed to determine the length of a string. Parameter is a string expression

1. Calculate (Eval)- is intended to evaluate an expression in the context of some grouping. The function is used for compatibility with previous versions of the platform. It is recommended to use the CalculateExpression function instead.

Syntax:
Calculate(Expression, Grouping, CalculationType)

Options :

Expression(Line). Contains a calculated expression;
Grouping(Line). Contains the name of the grouping in the context of which the expression is to be evaluated. If an empty string is used as the grouping name, the calculation will be performed in the context of the current grouping. If the GrandTotal string is used as the group name, the calculation will be performed in the context of the grand total. Otherwise, the calculation will be performed in the context of the parent grouping with the same name.
For example:
Sum(Sales.SumTurnover) / Calculate("Sum(Sales.SumTurnover)", "Total").
In this example, the result will be the ratio of the amount for the "Sales.AmountTurnover" field of the grouping record to the amount of the same field in the entire layout.
Calculation type(Line). If this parameter is set to "TotalTotal", the expression will be calculated for all grouping records. If the value of the parameter is "Grouping", the values will be calculated for the current grouping group record.

2. Evaluate Expression (EvalExpression) - is intended to evaluate an expression in the context of some grouping. The function takes into account the selection of groupings, but does not take into account hierarchical selections. The function cannot be applied to a grouping in the group selection of that grouping.

Syntax:
CalculateExpression(Expression, Grouping, CalculationType, Start, End, Sort, HierarchicalSort, ProcessingIdenticalOrderValues)

Options :

Expression(Line). Contains a calculated expression;
Grouping(Line). Contains the name of the grouping in the context of which the expression is to be evaluated. If an empty string is used as the grouping name, the calculation will be performed in the context of the current grouping. If the GrandTotal string is used as the group name, the calculation will be performed in the context of the grand total. Otherwise, the calculation will be performed in the context of the parent grouping with that name;
Calculation type(Line). If this parameter is set to "TotalTotal", the expression will be calculated for all grouping records. If the value of the parameter is "Grouping", the values will be calculated for the current grouping group record. If the parameter is set to "Non-Resource Grouping", then when calculating the function for a group record by resource, the expression will be evaluated for the first group record of the original grouping. When evaluating the CalculateExpression function with the value "GroupingNonResource" for group records that are not groupings by resource, the function is evaluated in the same way as it would be evaluated with the value of the "Grouping" parameter. The data composition layout builder, when generating a data composition layout when outputting a field - a resource by which grouping is performed, to the layout, outputs to the layout an expression calculated using the CalculateExpression function with the specified "GroupingNon-Resource" parameter. For other resources grouped by resource, normal resource expressions are returned. If the parameter is set to "Hierarchy", then the expression must be evaluated for the parent hierarchical record, if there is one, and for the entire grouping, if there is no parent hierarchical record. The layout builder, when generating an expression for the % in Hierarchy Group field, generates an expression containing the relationship of the resource expression to the CalculateExpression function for the resource expression being calculated for the current grouping with calculation type Hierarchy.
Start. Indicates from which record the fragment should begin, in which aggregate expression functions should be calculated, and from which record to obtain field values outside of aggregate functions. A string containing one of:
- "First" It is necessary to obtain the first grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the beginning of the grouping. The resulting value must be an integer greater than zero. For example, First(3) – receiving the third record from the beginning of the grouping. If the first record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get First(4), then it is considered that there are no records.
- "Last" You need to get the last grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset from the end of the grouping. The resulting value must be an integer greater than zero. For example, Last(3) – receiving the third record from the end of the group. If the last record is outside the grouping, then it is considered that there are no records. For example, if there are 3 records, and you want to get Last(4), then it is considered that there are no records.
- "Previous" You need to get the previous grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset back from the current grouping record. For example, Previous(2) – getting the previous from the previous record. If the previous record is outside the grouping (for example, the second grouping record requires getting Previous(3)), then the first grouping record is obtained. When receiving the previous record for the grouping total, the first record is obtained.
- "Next" You need to get the next grouping record. After the word in brackets, you can specify an expression, the result of which will be used as an offset forward from the current grouping entry. For example, Next(2) – getting the next from the next record. If the next record goes beyond the grouping, then it is considered that there are no records. For example, if there are 3 entries and the third entry receives Next, then it is considered that there are no entries. When the next record is received for the grouping total, it is considered that there is no record.
- "Current" You need to get the current record. When retrieving for a grouping total, the first record is obtained.
- "BoundaryValue". The need to get a record by the specified value. After the word LimitingValue in parentheses, you need to indicate the expression with the value of which you want to start the fragment, the first ordering field. The first record whose ordering field value is greater than or equal to the specified value will be returned as the record. For example, if the Period field is used as the ordering field, and it has the values 01/01/2010, 02/01/2010, 03/01/2010, and you want to get the LimitingValue(DateTime(2010, 1, 15)), then a record with the date 02/01 will be obtained. 2010.
End. Indicates to which record the fragment should be continued, in which the aggregate expression should be calculated. A string containing one of:
- "First"
- "Last"
- "Previous"
- "Next"
- "Current".
- "BoundaryValue".
Sorting. A string that lists the expressions, separated by commas, in the direction of which the sequence should be ordered. If not specified, then the ordering is performed in the same way as for the grouping for which the expression is evaluated. After each expression, you can specify the keyword Ascending, for ordering in ascending order, Descending, for ordering in descending order, Auto-Ordering, for ordering the reference fields by the fields by which you want to order the object being referenced. The word Auto Order can be used with both the word Ascending and the word Descending.
HierarchicalSorting. Similar to sorting. Used to organize hierarchical records. If not specified, the layout compositor generates the ordering according to the ordering specified in the Sort parameter.
Processing Same Values of Order. A string containing one of:
- "Together" means that a sequence of ordered records is used to determine the previous and next records;
- "Separately" means that the previous and next records are determined based on the values of the ordering expressions;
For example, if the resulting sequence is ordered by date:
1. January 01, 2001 Ivanov M. 10
2. January 02, 2001 Petrov S. 20
3. January 02, 2001 Sidorov R. 30
4. January 03, 2001 Petrov S. 40
When using processing of identical values of the order "Separately", the previous one for record 3 will be record 2, and when using "Together" - record 1. And the fragment for the current record for record 2 for "Separately" will be record 2, and for "Together" - records 2 and 3. Thus, the total for the current record for “Separately” will be 20, and for “Together” - 50. When “Together” is specified in the Start and End parameters, you cannot specify an offset for the positions “First”, “Last”, "Previous", "Next". The default value is "Separate".

Example:
Obtaining the ratio of the amount for the "Sales.AmountTurnover" field of a grouping record to the amount of the same field in the entire layout:
Sum(Sales.SumTurnover) / CalculateExpression("Sum(Sales.SumTurnover)", "Total").

This example calculates the value of the current hierarchy:
Choice
When Level() > 0
Then EvaluateExpression("Reference", "Hierarchy")
Otherwise Null
End

Notes:
The function takes into account the selection of groupings, but does not take into account hierarchical selections. The function cannot be applied to a grouping in the group selection of that grouping. For example, in selecting the Nomenclature grouping, you cannot use the expression CalculateExpression("Sum(SumTurnover)", "TotalTotal") > 1000 . But such an expression can be used in hierarchical selection. If the end record precedes the start record, then it is considered that there are no records for calculating detailed data and calculating aggregate functions. When calculating interval expressions for a grand total (the Grouping parameter is set to "GrossTotal"), it is assumed that there are no records for calculating detailed data and calculating aggregate functions. When generating an expression for the CalculateExpression function, the layout compositor, if the ordering expression contains fields that cannot be used in grouping, replaces the CalculateExpression function with NULL.

3. Evaluate Expression With Group Array (EvalExpression With Group Array) - the function returns an array, each element of which contains the result of calculating an expression for grouping by the specified field.

Syntax:
CalculateExpressionWithGroupArray (Expression, GroupFieldExpressions, SelectRecords, SelectGroups)

Options :

Expression(String) - the expression to be evaluated. For example, "Amount(AmountTurnover)";
FieldExpressionsGroups
Selection of Records
Selection of Groups- selection applied to group records. For example: "Amount(AmountTurnover) > &Parameter1".

Example:
Maximum(CalculateExpressionWithGroupArray("Amount(AmountTurnover)", "Counterparty"));

The layout builder, when generating expressions for the display of a custom field whose expression contains only the CalculateArrayWithGroup function, generates the display expression so that the data displayed by the views and the data are ordered.
For example, for a custom field with the expression:
CalculateExpressionWithGroupArray("Amount(AmountTurnover)", "Counterparty")
The layout builder will generate the following expression for output:
ConnectRows(Array(Order(CalculateExpressionWithGroupingValueTable("View(Sum(DataSet.AmountTurnover)), Amount(DataSet.AmountTurnover)", "DataSet.Account"), "2")))

4. EvalExpressionWithGroupValueTable - the function returns a table of values, each element of which contains the result of calculating an expression for grouping by the specified field.

Syntax:
CalculateExpressionWithGroupValueTable (Expression, GroupFieldExpressions, SelectRecords, SelectGroups)

Options :

Expression(String) - the expression to be evaluated. A line can contain multiple expressions separated by commas. After each expression there may be an optional keyword AS and the name of the value table column. For example: "Counterparty, Amount (AmountTurnover) As Sales Volume."
FieldExpressionsGroups- expressions of grouping fields, separated by commas. For example, "Counterparty, Party";
Selection of Records- an expression applied to detail records. For example, "Delete Flag = False." If this parameter uses an aggregate function, an error will occur when composing the data;
Selection of Groups- selection applied to group records. For example: "Amount(AmountTurnover) > &Parameter1".

Example:
CalculateExpressionWithGroupValueTable("Account AS Counterparty, Amount(AmountTurnover) AS SalesVolume", "Account")

The result of this function will be a table of values with columns Counterparty and Sales Volume, which will contain counterparties with their sales volumes.
The layout builder, when generating a layout, converts function parameters into terms of data layout layout fields. For example, the Account field will be converted to DataSet.Account.
For example, a custom field with the expression:
CalculateExpressionWithGroupValueTable("Account, Amount(AmountTurnover)", "Account")
The layout builder will generate the following expression for output:
ConnectRows(GetPart(Order(CalculateExpressionWithGroupingValueTable("DataSet.Account, DataSet.AccountRepresentation, Sum(DataSet.AmountTurnover), View(DataSet.AmountTurnover), DataSet.OrderingField", "DataSet.Account"), "5, 1, 3" ), "2, 4"))

40. Functions of common modules

A data composition engine expression may contain calls to functions of global common configuration modules. No additional syntax is required to call such functions.

Example:
AbbreviatedName(Documents.Link, Documents.Date, Documents.Number)

In this example, the "AbbreviatedName" function will be called from the general configuration module.
Note that the use of common module functions is only permitted if the appropriate data composition processor parameter is specified.
Additionally, functions of common modules cannot be used in custom field expressions.

If an array or a table of values is used as a parameter, the function returns a string containing a string representation of all the elements of the array, separated by the characters "; ". If any element has an empty string representation, then the string "<Пустое значение>".

Example:
Row(SalesDate)

Proper use of a data composition scheme (DCS) allows you to:

significantly reduce the time required to develop a report;
eliminate the need to create a managed form handler;
get a beautiful result with the possibility of additional customization by the user.

But not all developers make the most of the scheme’s capabilities, since not all of its settings are obvious and intuitive. In particular, many people know that in 1C SKD there are calculated fields, however, they do not fully understand the scope of their use and methods of working with them.

What is a calculated field

In most cases, the data source in the layout diagram is a query. In principle, within the query itself you can already use various formulas, constructions and expressions. A natural question arises: why do we need duplicate functionality?

The fact is that the access control system is something more than just displaying the result of a query, and this is clearly visible from the diagram creation form (Fig. 1).

Calculated fields allow you to perform certain actions with the generated data set:

Output an array of data received by a request into a specific cell, combining several lines into one;
Access the export functions of the general module;
Execute the various expressions available for the layout language and use the special EvaluateExpression functions.

Let's go through this list.

Array of values in one cell

Let's simulate a situation where it is necessary to receive all receipt document numbers for a counterparty in a separate cell:

Thus, we have created an additional calculation field in our scheme;

As you can see from the example above, there are no difficulties in adding and processing calculated fields. We used two functions: Array() and ConnectRows().

A few words about the latter. In addition to the first parameter indicating the identifier of the array, values or values, two more can be set in it:

Element Separator – indicates which character will separate one array element or one row of a table of values from another (in our case, we omitted this parameter and a line break was assigned by default);
Column Separator – a character used to separate columns of a table of values (semicolon is used by default).

Accessing the export functions of a common module

Functions of a common module can act as a data source for filling a calculated field.

A few important points:

The function must be exportable;
If a function is located in a common module with the “Global” attribute set, it is called directly by name, otherwise the function must be called according to the “Shared module name” scheme. "Name of the function to be called."

As an example of use, we will take the same request for receipt documents and display it in a separate column. We will not describe the request itself; let’s move directly to the calculated fields:

Thus, we see that almost any data processor can be initialized from the access control system, which significantly expands the possibilities of using the scheme.

Layout language expressions

Quite often in a developer’s work a situation arises when it is necessary to display the result of division in the ACS field:

Calculate the average cost of the item;
All kinds of interest;
Calculations of average earnings, etc.

To avoid problems, in these cases it is advisable to enter a test for division by 0 into the calculated field.

This can be done using the construction “Choice When….Then… Otherwise… End”.

At the end, a few words about the fairly new function CalculateExpression(). With its help, in particular, you can calculate deviations in cost between the current and previous lines, cumulative balance, etc.

Let's say you can get the Document Amount from the previous line of our request by specifying the value Calculate Expression ("Document Amount", "Previous Amount") in the "Expression" field.
