Smart SAP Assistant

• What is the cause and solution for SAP error message /AIF/RFC_TRANSFER001 - CIF Data Transfer already running ?

  The SAP error message /AIF/RFC_TRANSFER001 CIF Data Transfer already running typically indicates that a CIF (Core Interface) data transfer process is already in progress, and a new request to start the same process cannot be executed until the current one is completed. This can happen in scenarios where multiple processes are trying to initiate the same data transfer simultaneously.
  Cause:
  
  Concurrent Execution: Another instance of the CIF data transfer is already running, which prevents a new instance from starting.
  Long-Running Processes: The existing CIF data transfer process may be taking longer than expected due to large data volumes or performance issues.
  System Lock: There may be a lock on the CIF data transfer process in the system, preventing new requests from being processed.
  
  Solution:
  
  
  Check Running Processes:
  
  Use transaction SM37 to check for any running jobs related to CIF data transfer. Look for jobs with a status of "Running" or "Waiting".
  If you find a job that is stuck or taking too long, you may need to analyze it further.
  
  
  
  Wait for Completion:
  
  If another process is running, the simplest solution is to wait for it to complete. Monitor the job status in SM37.
  
  
  
  Terminate Stuck Processes:
  
  If you determine that a process is stuck and not progressing, you may need to terminate it. This can be done in SM37 by selecting the job and choosing the option to cancel it.
  
  
  
  Review Logs:
  
  Check the application logs for any errors or warnings that might indicate why the CIF data transfer is taking longer than expected. You can use transaction SLG1 to view application logs.
  
  
  
  Increase Performance:
  
  If CIF data transfers are frequently taking too long, consider optimizing the data transfer process. This could involve:
  
  Reducing the volume of data being transferred at one time.
