fieldsets_in_scope

Description

You can use this function to retrieve the Field Sets that are available within a FOREACH WIZARD loop for use in the model. This function uses the same logic to select Field Sets from a Data Definition as used by the TEXTBLOCK statement with the DATA_DEFINITION and PATH keywords.

fieldsets_in_scope ( datainput; path; fieldsets )

The function has three parameters:

• datainput, type DATASTRUCTURE; the Data Structure that would be used as DATA_DEFINITION parameter to the TEXTBLOCK statement.
• path, type TEXT; the Path used as PATH parameter to the TEXTBLOCK statement.
  The content of the path parameter is subject to the same restrictions as documented for the PATH parameter on the TEXTBLOCK statement.
• fieldsets, type MAP FIELDSET; this MAP receives a copy of the Field Sets, using the name of the Field Set as key in the MAP.

The result of the function is type BOOL; if the function succeeds it returns TRUE, otherwise FALSE.

Example

DATASTRUCTURE FIS
  BEGIN
    MAP FIELDSET FieldSets
  END

DECLARE sets DEFINED_AS FIS

BOOL res := fieldsets_in_scope (data_definition; path; sets.FieldSets)
TEXT customer := sets.FieldSets["Customer"].FirstName + " " + sets.FieldSets["Customer"].LastName

This example retrieves the active Field Sets, and then uses the Customer.FirstName and Customer.LastName fields from this set.
