dox42 uses the same DataProvider as a SSRS report. Therefore, all the necessary setup which is influencing the DataProvider from the D365 FSCM side is also influencing the DataProvider of dox42. An example would be the form setup in the Accounts receivable section. (Accounts receivable > Setup > Forms > Form setup).
The form setup contains the general setup (General tab) of a report as well as a specific one.

Form set up > General tab in D365 FSCM

Form set up > Invoice tab in D365 FSCM
