• What is the cause and solution for SAP error message CURTO1051 - A concurrent initial data transfer has already been started ?

  The SAP error message CURTO1051 indicates that a concurrent initial data transfer has already been started, which means that the system is currently processing an initial data transfer for a particular object or process, and another attempt to start a similar transfer is being blocked.
  Cause:
  
  Concurrent Processes: The most common cause of this error is that there is already an ongoing initial data transfer for the same object or data set. SAP does not allow multiple concurrent initial data transfers for the same data set to prevent data inconsistencies.
  System Lock: The system may have a lock on the data transfer process, which prevents new requests from being initiated until the current process is completed.
  Long-running Processes: If the initial data transfer is taking longer than expected, it may lead to this error when another attempt is made to start the transfer.
  
  Solution:
  
  Check Running Processes: Use transaction codes like SM37 (Job Monitoring) or SM66 (Global Work Process Overview) to check if there are any ongoing data transfer jobs. If you find a job that is still running, you may need to wait for it to complete.
  Terminate Long-Running Jobs: If a job is stuck or taking too long, you may consider terminating it (if appropriate) to free up the system for new requests. Be cautious with this approach, as terminating a job can lead to data inconsistencies.
  Retry Later: If the initial data transfer is still in progress, the simplest solution may be to wait until it completes and then retry the operation.
  Check for Locks: Use transaction code SM12 to check for any locks that may be preventing the new data transfer from starting. If you find locks that are no longer needed, you can release them.
  Review Logs: Check the application logs (transaction SLG1) for any additional information or errors that may provide more context about the ongoing data transfer.

  System Performance: If this error occurs frequently, it may be worth investigating the overall performance of the system to ensure that it can handle concurrent processes effectively.
  
  By following these steps, you should be able to resolve the CURTO1051 error and successfully initiate the initial data transfer.
