This error indicates that there is an attempt to start a new replication action for an object that is already configured and active in the system. The message suggests that you need to stop the existing replication action before starting a new one.
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate Configuration: You are trying to create a new replication configuration for an object that is already being replicated.
  Active Replication: The existing replication process for the object is still active, and the system does not allow multiple active replications for the same object.
  Incorrect Management of Replication Tasks: There may be a lack of proper management of replication tasks, leading to attempts to start a new task without stopping the existing one.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Replication Configuration:
  
  Go to the SLT configuration transaction (usually LTRC).
  Check the list of existing replication configurations to see if the object in question is already listed.
  
  
  
  Stop the Existing Replication:
  
  If you find that the object is already configured, you need to stop the existing replication.
  In the SLT configuration, select the object and choose the option to stop or deactivate the replication.
  
  
  
  Delete or Modify the Configuration:
  
  If you need to change the configuration, you may need to delete the existing configuration or modify it as per your requirements.
  
  
  
  Restart the Replication:
  
  After stopping the existing replication, you can proceed to start the new replication action for the object.
  
  
  
  Check for Errors:
  
  After making changes, monitor the SLT logs for any additional errors or warnings that may arise.
