If I'm understanding your Q (that you want to see which objects depend on a
certain query) in Access 2007 it is super easy to do this. There is a really
nifty tool called object dependencies under the database tools tab.
Open a query (design view, run it, whatever) then click the object
dependencies. I think it asks you if you're ok with closing everything so it
can run its 'scan' of your database's relationships, but then it will bring
up a side bar like the properties tab that tells you what objects and their
types are related, so there should be a section for "reports" that lists all
the reports files associated with a particular query
