  Check the Group Configuration: Ensure that you are not trying to modify a default group. If you need to make changes, consider creating a new custom group instead of modifying the default one.
  Review the OData Service: Check the implementation of the OData service to ensure that it is not attempting to modify the default group. If necessary, adjust the service logic to avoid this.
  User Authorizations: Verify that the user has the appropriate authorizations to perform the intended action. If not, you may need to adjust the user's roles and permissions.
  Use Transaction /IWFND/MAINT_SERVICE: If you are managing OData services, use this transaction to check the service registration and ensure that the service is correctly configured.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP Gateway you are using for any additional guidance or updates regarding this error.
