• What is the cause and solution for SAP error message SUI2_CATALOG_PFCG004 - Error during existence check of function module &1 at RFC destination &2 ?

  The SAP error message SUI2_CATALOG_PFCG004 indicates that there is an issue with the existence check of a function module at a specified RFC (Remote Function Call) destination. This error typically arises in the context of role management and authorization checks in SAP, particularly when using transaction codes related to role maintenance (like PFCG).
  Cause:
  
  Function Module Not Found: The function module specified in the error message (&1) does not exist in the system or is not available in the specified RFC destination (&2).
  RFC Destination Issues: The RFC destination may not be correctly configured, or there may be connectivity issues between the systems.
  Authorization Issues: The user executing the transaction may not have the necessary authorizations to access the function module.
  Transport Issues: If the function module was recently transported, it may not have been activated or may not exist in the target system.
  
  Solution:
  
  Check Function Module: Verify that the function module exists in the system. You can do this by using transaction SE37 (Function Builder) and checking if the function module is present and active.
  Check RFC Destination: Use transaction SM59 to check the configuration of the RFC destination. Ensure that it is correctly set up and that the connection is working. You can test the connection from this transaction.
  Authorization Check: Ensure that the user has the necessary authorizations to access the function module. You can check this using transaction SU53 after the error occurs to see if there are any authorization failures.
  Transport Check: If the function module was recently transported, ensure that it has been activated in the target system. You can also check the transport logs for any issues.
  System Logs: Check the system logs (transaction SM21) for any additional error messages or warnings that might provide more context about the issue.
