Application Version "Where Used" Query ??

Application Version \"Where Used\" Query ??

I'm looking for any source that can point to where an application version
can be traced to 'where it is used' in other versions. Sounds confusing,
but as we know, the audit trail can lead to many other processing option
versions that 'touch' many more. I can't seem to find any report or query
that would tell me where a specific application/version is used. Any help
would be greatly appreciated.
