Smart SAP Assistant

• What is the cause and solution for SAP error message RSDRI_HDB128 - Data is already being transferred. Stop process (SM66). ?

  The SAP error message RSDRI_HDB128 indicates that a data transfer process is already in progress, and the system is preventing a new transfer from starting until the current one is completed. This error typically occurs in the context of data extraction or loading processes, particularly when using SAP HANA as the database.
  Cause:
  
  
  Concurrent Data Transfer: The most common cause of this error is that a data transfer process (like a data load or extraction) is already running. This can happen if:
  
  A previous data load has not yet completed.
  A job is stuck or taking longer than expected.
  Multiple users or processes are trying to initiate the same data transfer simultaneously.
  
  
  
  System Locking: The system may have locking mechanisms in place to prevent data inconsistencies, which can lead to this error if another process is already accessing the same data.
  
  
  Solution:
  
  
  Check Running Processes:
  
  Use transaction code SM66 (Global Work Process Overview) to check for any active processes that might be related to the data transfer. Look for any jobs that are currently running and see if they are stuck or taking too long.
  
  
  
  Terminate Stuck Processes:
  
  If you identify a process that is stuck or not progressing, you may need to terminate it. You can do this from the SM66 screen by selecting the process and choosing the option to terminate it.
  
  
  
  Wait for Completion:
  
  If the process is running as expected, you may simply need to wait for it to complete before starting a new data transfer.
  
  
  
  Review Job Scheduling:
  
  If this error occurs frequently, consider reviewing your job scheduling to ensure that data transfer jobs are not overlapping. You may want to stagger the execution times of these jobs.
  
  
  
  Check for Locks:
  
  Use transaction SM12 to check for any locks that might be preventing the data transfer from proceeding. If you find locks that are no longer needed, you can delete them.
  
  
  
  System Performance:
  
  If the system is under heavy load, it may cause delays in processing. Monitor system performance and consider optimizing resource allocation if necessary.

  Documentation: Review SAP documentation related to data extraction and loading processes, especially if you are using SAP BW or SAP HANA.
  
  
  By following these steps, you should be able to resolve the RSDRI_HDB128 error and ensure that your data transfer processes run smoothly.
