• What is the cause and solution for SAP error message MCW_AA_STR013 - Variable &1 is not of type multiple selection (Selection Options) ?

  The SAP error message MCW_AA_STR013 indicates that a variable you are trying to use in a selection screen is not of the type "multiple selection" (Selection Options). This typically occurs when you are trying to use a variable that is expected to hold multiple values, but it is defined as a single value variable instead.
  Cause:
  
  Variable Definition: The variable in question is defined in a way that does not support multiple selections. For example, it might be defined as a single value or a simple data type rather than a table or a structure that can hold multiple entries.
  Incorrect Usage: The variable is being used in a context where multiple selections are expected, such as in a selection screen or a report that allows users to select multiple values.
  
  Solution:
  
  
  Check Variable Definition: 
  
  Go to the variable definition in the relevant ABAP program or query.
  Ensure that the variable is defined as a multiple selection type. In ABAP, this is typically done using the SELECT-OPTIONS statement or by defining the variable as a table type that can hold multiple entries.
  
  
  
  Modify the Code:
  
  If you are using a variable that should allow multiple selections, change its definition to use SELECT-OPTIONS instead of PARAMETERS or a single value variable.
  Example:
  SELECT-OPTIONS: s_field FOR your_table-field.
  
  This allows users to select multiple values for s_field.
  
  
  
  Review the Report/Program Logic:
  
  Ensure that the logic in your report or program correctly handles the multiple selection variable. If you are processing the variable, make sure to loop through the entries if necessary.
  
  
  
  Testing: After making the changes, test the report or program to ensure that the error is resolved and that the multiple selection functionality works as expected.
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal for detailed information on selection options and variable types.
  ABAP Programming: Familiarize yourself with the differences between PARAMETERS, SELECT-OPTIONS, and TABLES in ABAP to avoid similar issues in the future.
  Debugging: If you continue to face issues, consider using the debugger to trace the variable's type and usage throughout the program.
  
  By following these steps, you should be able to resolve the error message MCW_AA_STR013 and ensure that your variable is correctly set up for multiple selections.
