  Cause:
  
  Class Not Available: The specified class may not be defined or registered in the target system that the RFC destination points to.
  RFC Destination Issues: The RFC destination may be incorrectly configured, pointing to the wrong system or not set up properly.
  Authorization Issues: The user or service account used for the RFC connection may not have the necessary authorizations to access the specified class.

  Solution:
  
  
  Check Class Availability:

  Check Authorizations:
  
  Ensure that the user or service account used for the RFC connection has the necessary authorizations to access the class. You may need to check roles and authorizations in transaction PFCG.
