FMAVC523 - Details

• The SAP error message FMAVC523 indicates that a specific object (like a function module, class, or method) is not found in the SAP namespace. This typically occurs when you are trying to access or use an object that is either not defined in the system or is defined in a non-standard namespace (like a custom namespace).
  
  Cause:
  
  Non-Existent Object: The object you are trying to access does not exist in the system.
  Incorrect Namespace: The object is defined in a custom namespace (e.g., Z or Y) and is not recognized in the standard SAP namespace.
  Transport Issues: The object may not have been transported correctly from the development environment to the production environment.
  Authorization Issues: You may not have the necessary authorizations to access the object.
  
  
  Solution:
  
  Check Object Existence: Verify if the object (function module, class, etc.) exists in the system. You can do this by using transaction codes like SE37 (for function modules) or SE80
