• What is the cause and solution for SAP error message RSMPC126 - Master data deletion process already running for an IO of data target &1 ?

  The SAP error message RSMPC126 indicates that there is an ongoing master data deletion process for a specific InfoObject (IO) in the data target. This typically occurs in the context of data warehousing or data extraction processes, particularly when using SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error occurs when:
  
  A master data deletion process is already in progress for the specified InfoObject.
  A second attempt to delete the same master data is initiated before the first process has completed.
  There may be a lock on the InfoObject due to the ongoing deletion process, preventing any new deletion requests from being processed.
  
  Solution:
  To resolve the RSMPC126 error, you can take the following steps:
  
  
  Check for Running Processes:
  
  Use transaction code SM37 to check for any background jobs that are currently running. Look for jobs related to master data deletion for the specified InfoObject.
  If you find a job that is still running, you may need to wait for it to complete.
  
  
  
  Monitor the Deletion Process:
  
  If the deletion process is taking longer than expected, you may want to investigate why it is taking so long. Check for any performance issues or data volume that might be causing delays.
  
  
  
  Cancel the Running Job (if necessary):
  
  If you determine that the running job is stuck or not progressing, you can cancel it from the SM37 transaction. Be cautious when doing this, as it may lead to data inconsistencies.
  
  
  
  Retry the Deletion:
  
  Once the ongoing deletion process has completed or has been canceled, you can retry the master data deletion process for the InfoObject.
  
  
  
  Check for Locks:
  
  You can also check for any locks on the InfoObject using transaction code SM12. If there are locks that are not being released, you may need to investigate further or contact your SAP Basis team.
