• What is the cause and solution for SAP error message SV118 - Make any changes and new entries in the SAP namespace only ?

  The SAP error message SV118, which states "Make any changes and new entries in the SAP namespace only," typically occurs when a user attempts to create or modify objects (like function modules, classes, or other development objects) in a namespace that is not designated for custom development. This is a part of SAP's namespace management to ensure that standard SAP objects are not inadvertently modified or overwritten.
  Cause:
  
  Namespace Restrictions: SAP has a defined namespace structure where certain namespaces are reserved for SAP standard objects (e.g., /SAP/) and others are reserved for customer-specific developments (e.g., /Z* or /Y*).

  Solution:
  
  Use the Correct Namespace: Ensure that you are creating or modifying objects in the appropriate namespace. For custom developments, use a namespace that starts with /Z or /Y.
  Check Authorizations: Verify that you have the necessary authorizations to create or modify objects in the desired namespace.
  Transport Requests: If you are working in a transport request, ensure that the request is correctly configured to include the objects you are trying to create or modify.
  Consult Documentation: Refer to SAP documentation or your organization's development guidelines to understand the proper use of namespaces.
