• What is the cause and solution for SAP error message ESH_EX055 - Change pointer migration: Successfully migrated: &1, already present: &2 ?

  The SAP error message ESH_EX055 relates to the change pointer migration process in the SAP system, specifically within the context of the Enterprise Search (ES) framework. This message indicates that during the migration of change pointers, some change pointers were successfully migrated, while others were already present in the target system.
  Cause:
  The error message is triggered when the system attempts to migrate change pointers that have already been processed or exist in the target system. This can happen due to several reasons:
  
  Duplicate Change Pointers: The change pointers being migrated may already exist in the target system, leading to a conflict.
  Incomplete Migration: Previous migration attempts may not have been fully completed, leaving some change pointers in a state that causes them to be recognized as already present.
  System Configuration: There may be configuration issues or inconsistencies in the source and target systems that lead to this situation.
  
  Solution:
  To resolve the issue indicated by the ESH_EX055 message, you can take the following steps:
  
  
  Check Migration Logs: Review the logs of the migration process to identify which change pointers were successfully migrated and which were already present. This can provide insights into the specific pointers causing the issue.
  
  
  Clean Up Change Pointers: If you identify that certain change pointers are indeed duplicates or no longer needed, you can clean them up from the target system. This may involve deleting or archiving old change pointers.
  
  
  Re-run Migration: After cleaning up the change pointers, you can attempt to re-run the migration process. Ensure that the migration settings are correctly configured to avoid duplication.
  
  
  Check System Configuration: Ensure that both the source and target systems are correctly configured for change pointer handling. This includes checking settings related to the Enterprise Search and change pointer management.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to change pointer migration and Enterprise Search for any specific guidelines or recommendations.
