• What is the cause and solution for SAP error message CNV_IUUC_REPLICATION091 - Replication for &1 already started ?

  The SAP error message CNV_IUUC_REPLICATION091 indicates that a replication process for a specific object (denoted by &1) has already been initiated. This error typically occurs in the context of SAP Landscape Transformation (SLT) or data replication scenarios where the system is trying to start a replication process that is already in progress.
  Cause:
  
  Concurrent Replication: The most common cause is that a replication job for the specified object is already running. This can happen if multiple attempts are made to start the same replication process.
  System Configuration: There may be configuration settings that allow for only one instance of a replication job to run at a time.
  Job Overlap: If a previous job has not completed or has failed, it may still be holding onto the replication lock.
  
  Solution:
  
  Check Running Jobs: Use transaction codes like SLT_MONITOR or SM37 to check for any active replication jobs. If you find that a job is already running for the specified object, you may need to wait for it to complete.
  Terminate Stuck Jobs: If a job is stuck or has failed, you may need to terminate it. This can be done through the job monitoring transactions mentioned above.
  Review Logs: Check the logs for the replication process to identify any issues that may have caused the job to hang or fail. This can provide insights into whether the job can be restarted or if further action is needed.
  Adjust Configuration: If necessary, review the configuration settings for the replication process to ensure that they align with your operational requirements. This may involve adjusting parameters related to job concurrency.
  Retry the Process: Once you have confirmed that no other replication job is running for the object, you can attempt to start the replication process again.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SLT_MONITOR, SM37, and SLT_CONFIG for monitoring and managing replication jobs.
  Documentation: Refer to SAP Help documentation for SLT and data replication for best practices and troubleshooting steps.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide patches related to replication errors.
