No, unless the report is a procedure/finction/class inside the application.
Sometimes it is convenient to create a separate app and call all reports via this application.

>In my architecture, functions are spread among various .app files. I would like to call an FRX file that is in a different app from the app that issues the REPORT FORM command, something like this:
>
> REPORT FORM MyFrx IN MyOtherApp

>Is this possible?
