Indexes can only be created over 1 Table/PF.
Joined logical files can be created over multiple files ... but the access
path can only be built over one of the joined files, i.e. all key fields
must be from the same file/table!

Subject: In SQL, can you create an index with JOIN's?

I seem to remember that you can only create indexes over one table, but I
have a vague memory of JOIN tables being introduced.

Or did I see something in a different implementation with something like
that?

I can't find the answer to that in the docs.
