This can happen in various scenarios, such as when you are working with custom interfaces or data mappings.
  Cause:
  
  Unsaved Changes: The primary cause of this error is that there are unsaved changes in the custom data link that you are trying to reload. The system prevents reloading to avoid losing any unsaved data.

  Reload the Interface: After saving, try reloading the interface or data link again to see if the error persists.
  Check for Multiple Sessions: If you have multiple sessions open, close any unnecessary ones and try again. Sometimes, session conflicts can lead to errors.
  Review Configuration: Check the configuration of the custom data link for any inconsistencies or errors. Ensure that all required fields and settings are correctly configured.
  Clear Cache: In some cases, clearing the cache of the application or the browser (if using a web interface) can help resolve issues related to stale data.
