• What is the cause and solution for SAP error message SWP097 - Error at end of an UNTIL loop ?

  The SAP error message SWP097, which indicates "Error at end of an UNTIL loop," typically occurs in the context of ABAP programming when there is an issue with the structure or logic of a loop that uses the UNTIL statement. This error can arise due to various reasons, such as incorrect loop conditions, improper handling of loop variables, or issues with the data being processed within the loop.
  Causes:
  
  Incorrect Loop Condition: The condition specified in the UNTIL statement may not be valid or may lead to an infinite loop.
  Data Issues: The data being processed within the loop may not be in the expected format or may lead to unexpected results.
  Variable Initialization: Loop control variables may not be properly initialized before entering the loop.
  Logical Errors: There may be logical errors in the code that prevent the loop from terminating correctly.
  
  Solutions:
  
  Review Loop Condition: Check the condition specified in the UNTIL statement to ensure it is logically sound and will eventually evaluate to true.
  DO.
    " Your processing logic here
    IF <condition>.
      EXIT.
    ENDIF.
  ENDDO.
  
  Initialize Variables: Ensure that all loop control variables are properly initialized before the loop starts.
  Debugging: Use debugging tools to step through the loop and observe the values of variables and conditions to identify where the logic may be failing.
  Check Data: Validate the data being processed in the loop to ensure it meets the expected criteria and format.
  Error Handling: Implement error handling within the loop to manage unexpected situations gracefully.
