Thanks again. I've created this dummy form with no fields. Then I went to settings>forms>"set how different roles use these forms" and set the value in every row of Grid Edit to this dummy form. When I view a parent record and click on "grid edit" in the embedded child report I'm still able to create orphaned child records. The dummy form isn't being used. Am I misunderstanding the solution you suggested? Again, thanks for your responses.
Update: I see what's happening. The dummy form is used when a user tries to grid edit main projects page. It is not used when trying to grid edit the embedded report in the form which is what I am trying to accomplish.
