• What is the cause and solution for SAP error message TA720 - The SELTAB was changed by exit &1 in the cleanup phase ?

  The SAP error message TA720 indicates that the SELTAB (Selection Table) was modified by an exit during the cleanup phase of a report or transaction. This typically occurs when a user exit or enhancement modifies the selection criteria after the initial selection has been made, which can lead to inconsistencies or unexpected behavior in the report execution.
  Cause:
  
  User Exits or Enhancements: The most common cause of this error is a user exit or enhancement that modifies the selection table (SELTAB) during the cleanup phase. This can happen if the exit is not properly coded or if it is not intended to modify the selection criteria at that point in the program execution.
  Incorrect Logic: The logic within the user exit may be incorrect, leading to unintended modifications of the selection criteria.
  Multiple Exits: If there are multiple exits or enhancements that interact with the same selection table, they may conflict with each other, causing this error.
  
  Solution:
  
  Review User Exits: Check the user exits or enhancements that are associated with the report or transaction. Look for any modifications to the SELTAB and ensure that they are necessary and correctly implemented.
  Debugging: Use the debugger to trace the execution of the program and identify where the SELTAB is being modified. This can help pinpoint the exact exit or enhancement causing the issue.
  Modify Logic: If you identify that a user exit is incorrectly modifying the SELTAB, you may need to adjust the logic to ensure that it only modifies the selection criteria when appropriate.
  Consult Documentation: Review any documentation related to the user exits or enhancements to understand their intended behavior and ensure they are being used correctly.
  Testing: After making changes, thoroughly test the report or transaction to ensure that the error no longer occurs and that the expected results are achieved.
