• What is the cause and solution for SAP error message RD144 - Delta update only possible with status "Update successful" ?

  The SAP error message RD144 indicates that a delta update can only be performed when the status of the previous update is "Update successful." This error typically arises in the context of SAP's data transfer processes, particularly when dealing with delta updates in the SAP BW (Business Warehouse) or SAP ERP systems.
  Cause:
  The error occurs when there is an attempt to execute a delta update, but the previous update has not been completed successfully. This can happen due to several reasons, including:
  
  Previous Update Failure: The last delta update may have failed, leaving the system in a state where it cannot proceed with a new delta update.
  Inconsistent Data: There may be inconsistencies in the data that prevent the delta update from being processed.
  Locking Issues: There could be locks on the data that prevent the delta update from being executed.
  Configuration Issues: Incorrect configuration of the data source or the delta process can lead to this error.
  
  Solution:
  To resolve the RD144 error, you can follow these steps:
  
  
  Check Previous Update Status:
  
  Go to the relevant transaction (e.g., RSA1 for Data Warehousing Workbench) and check the status of the last delta update. Ensure that it has completed successfully.
  
  
  
  Analyze Error Logs:

  Reprocess Failed Updates:
  
  If the previous delta update failed, you may need to reprocess it. Depending on the situation, you might need to reset the delta queue or reinitialize the delta process.
  
  
  
  Check for Locks:
  
  Use transaction SM12 to check for any locks on the relevant tables. If there are locks, you may need to release them.
