  Solution:
  
  Use a Valid Namespace: Check the namespace you are trying to use and ensure it is not reserved. SAP namespaces typically start with a letter followed by a number of characters (e.g., Z or Y for custom development). You should use a custom namespace that is not reserved.
  Check Namespace Configuration: If you believe the namespace should be valid, check the configuration settings in your SAP system to ensure that the namespace is correctly set up and not restricted.
  Consult SAP Documentation: Refer to the SAP documentation or the SAP Community for guidance on which namespaces are reserved and which can be used for custom development.
