  The SAP error message "TK790 Namespace & cannot be used" typically indicates that there is an issue with the namespace you are trying to use in your SAP system. This error can occur in various contexts, such as when creating or modifying objects in the ABAP Workbench, or when working with custom development.
  Cause:
  
  Invalid Namespace: The namespace you are trying to use may not be valid or may not be registered in the SAP system.
