SPRX111 - Details

• The SAP error message SPRX111 indicates that you are trying to modify objects that belong to a different namespace than the one you are currently working in. In SAP, namespaces are used to organize and manage objects, and certain namespaces are reserved for specific purposes (e.g., SAP standard objects, customer-specific objects).
  
  Cause:
  The error occurs when:
  
  You attempt to change or modify an object (like a function module, class, or program) that is not in your development namespace.
