• What is the cause and solution for SAP error message WPPERS110 - Internal error. Tab number &1 is invalid ?

  The SAP error message:
  WPPERS110 Internal error. Tab number &1 is invalid
  typically occurs in the context of SAP Workflow or HR Personnel Administration processes, especially when dealing with personnel actions or infotypes in the HR module.
  
  Cause
  
  The error indicates that an internal program or workflow step is trying to access a tab (screen or data structure) identified by a tab number that does not exist or is invalid.
  This usually happens due to:
  
  Incorrect or inconsistent configuration of personnel actions or infotype screens.
  Custom enhancements or modifications that reference invalid tab numbers.
  Corrupted or incomplete data in the personnel action or infotype processing.
  A mismatch between the expected and actual screen layout or infotype structure.
  
  
  In HR Personnel Administration, this can occur if the personnel action is calling a tab that is not defined in the action profile or the screen sequence.
  
  
  Solution
  
  
  Check the Personnel Action Configuration:
  
  Go to transaction PE03 (Personnel Actions) and verify the action profile.
  Ensure that the tab numbers defined in the action profile correspond to valid infotypes and screen sequences.
  Correct any inconsistencies or missing tabs.
  
  
  
  Review Custom Enhancements:
  
  If there are user exits, BAdIs, or custom code enhancements related to personnel actions or workflows, check if they reference tab numbers.
  Debug the code to identify where the invalid tab number is being passed.
  Correct the logic to use valid tab numbers.
  
  
  
  Verify Infotype Screens:
  
  Use transaction PM01 or PM02 to check the screen sequences for the infotypes involved.
  Make sure the screens are active and properly assigned.
  
  
  
  Check Workflow or Process Configuration:
  
  If the error occurs during workflow processing, check the workflow steps and container elements.
  Ensure that the workflow is not trying to access a non-existent tab or screen.
  
  
  
  Debugging:
  
  Use transaction SE38 or SE80 to debug the program or workflow where the error occurs.
  Identify the point where the tab number is validated and why it is invalid.
