  The SAP error message ECRM_ISU203 typically indicates that there is an issue with the RFC (Remote Function Call) mode being active in the context of the IS-U (Utilities) module. This error can occur in various scenarios, particularly when there are issues with communication between systems or when certain configurations are not set correctly.
  Cause:
  
  RFC Configuration Issues: The RFC destination may not be configured correctly, or there may be issues with the connection to the remote system.
  System Lock: The system may be locked or busy, preventing the RFC call from being processed.
  Authorization Issues: The user or system may not have the necessary authorizations to perform the requested operation.
  Network Issues: There may be network connectivity problems between the systems involved in the RFC call.
  Transaction State: The transaction may be in a state that does not allow for RFC processing.
  
  Solution:
  
  
  Check RFC Configuration:
  
  Verify the RFC destination settings in transaction SM59. Ensure that the destination is correctly configured and that the connection test is successful.
  
  
  
  Check System Status:
  
  Ensure that the target system is up and running. You can check the status of the system in transaction SM51 to see if the application servers are active.
  
  
  
  Review Authorizations:
