Specifically, it suggests that multiple systems have been designated as the main system for a particular object, which is not allowed. The error message typically appears when you are trying to set up or execute data replication and the system detects that more than one system is marked as the main system for the same object.
  Cause:
  The primary cause of this error is that in the configuration of the Data Replication Framework, multiple systems have been incorrectly set as the main system for the same data object. This can happen due to:

  Update the configuration to ensure that only the selected system is marked as the main system.
  
  
  
  Review Replication Model:
  
  Check the replication model to ensure that it is correctly set up and that there are no conflicting entries.
  
  
  
  Transport Requests:
