  SAP Error Message: WG156 &1 condition change pointer was deleted
  Message Text:
  
  &1 condition change pointer was deleted
  
  Cause
  This error occurs when the system tries to access or update a condition change pointer that no longer exists or has been deleted. Condition change pointers are used in SAP to track changes in condition records (such as pricing conditions) for replication purposes, especially in ALE/IDoc scenarios.
  Typical scenarios causing this error:
  
  The condition change pointer record was deleted manually or by a cleanup job.
  The pointer was processed and removed before the current operation tried to access it.
  Inconsistent or outdated data in the condition change pointer tables.
  The system is trying to process a change pointer that was already processed and deleted.
  
  
  Background Information
  
  Condition Change Pointers are entries in tables like Axxx (where xxx is the application area, e.g., A304 for pricing conditions) that track changes in condition records.
  These pointers are used to trigger ALE/IDoc messages to replicate condition changes to other systems.
  The change pointer mechanism is controlled via transaction BD61 (Activate Change Pointers) and related programs.
  Change pointers are processed by programs like RBDMIDOC or custom ALE programs.
  
  
  Solution / How to Fix
  
  
  Check if the condition change pointer exists:
  
  Use SE16/SE16N to check the relevant change pointer table (e.g., A304 for pricing conditions).
  Verify if the pointer with the given key exists or was deleted.
  
  
  
  Check if the pointer was already processed:
  
  If the pointer was processed and deleted, the system should not try to access it again.
  Review the processing logic or program to ensure it handles already processed pointers correctly.
  
  
  
  Avoid manual deletion of change pointers:
  
  Do not delete change pointers manually unless you are sure they are no longer needed.
  If cleanup is necessary, ensure it is done after processing.
  
  
  
  Re-generate the change pointer if needed:
  
  If the pointer was deleted but the change still needs to be replicated, you may need to re-trigger the change pointer generation.
  This can be done by re-saving the condition record or running a report to regenerate change pointers.
  
  
  
  Check ALE/IDoc processing:
  
  Verify if the IDoc processing is consistent and no duplicate processing is attempted.
  Check transaction WE02 or WE05 for related IDocs and their status.
