  Check Authorizations: Ensure that the user has the necessary authorizations to access the data in the entity set. You can use transaction SU53 to analyze authorization issues.
  Review Backend Logs: Check the backend system logs for any errors that might indicate why the data retrieval is failing. This can include transaction SLG1 for application logs.
