It would be nice to have code available to find Transferfields usage for a RecordRef. Both from and to usage is needed. Specific extra code to filter on app-id comes to mind.

In my opinion this functionality is very handy in a test-app to check if all transferfield requirements are met, e.g., the app does not have some integer field in Sales Line and the same field as text in the Sales Invoice Line.

To be able to use this appropriately, in my opinion Transferfields should be made available for RecordRef, so we no longer need to declare all variables (see idea = https://experience.dynamics.com/ideas/idea/?ideaid=c6a30f75-0e4a-ed11-97b0-0003ff4594c9)
