• What is the cause and solution for SAP error message 5Z079 - Key & is not in customer namespace. Do you still want to copy it? ?

  The SAP error message 5Z079 indicates that you are trying to copy an object (such as a key, function module, or other development object) that is not in the customer namespace. In SAP, objects are typically categorized into different namespaces, and the customer namespace is reserved for custom developments. The error suggests that the object you are trying to copy is in a standard or non-customer namespace, which may lead to conflicts or issues if copied directly.
  
  Cause:
  
  Namespace Conflict: The object you are trying to copy is in a standard SAP namespace (like /SAP/ or /BAP/) and not in the customer namespace (usually starts with Z or Y).
  Development Guidelines: SAP has guidelines to prevent overwriting or modifying standard objects directly, which is why the system raises this error.
  
  
  Solution:
  
  Check the Object: Verify the object you are trying to copy. If it is a standard object, consider whether you really need to copy
