• What is the cause and solution for SAP error message WRF_APC537 - Multiple selection is not allowed ?

  The SAP error message WRF_APC537: Multiple selection is not allowed typically occurs in the context of SAP Advanced Planning and Optimization (APO) or related modules when a user or a process tries to input or select multiple values in a field or parameter where only a single value is permitted.
  
  Cause
  
  Multiple values entered where only a single value is allowed: The error arises because the selection screen, function module, or report expects a single value for a particular parameter or field, but multiple values (ranges, multiple single entries, or multiple selections) have been provided.
  Incorrect selection screen configuration: Sometimes, the selection screen or input parameter is defined to accept only a single value, but the user tries to input multiple values.
  Program or interface limitation: The underlying program logic or interface does not support multiple selections for that particular field.
  
  
  Solution
  
  
  Check the selection input:
  
  Review the selection criteria or input fields where the error occurs.
  Ensure that only a single value is entered for the field causing the error.
  Remove any multiple entries, ranges, or multiple selections.
  
  
  
  Adjust selection screen if possible:
  
  If you are a developer or have access to the program, check the parameter definition in the selection screen.
  Change the parameter to allow multiple selections if business logic permits (e.g., use SELECT-OPTIONS instead of PARAMETERS).
  Otherwise, enforce single value input.
  
  
  
  Consult documentation or SAP notes:
  
  Sometimes, this error is known and documented in SAP Notes with specific instructions.
