In my previous post, some people asked how we went about creating the report I talked about.

I asked the fellow who created this report internally. Here was his response, which I'm passing on to you. (Thanks Doug!)
NOTE: I've also attached the .RDL file he forwarded along.

Here is the query which gets current values along with the value of completed & remaining work from some prior date (and the prior date is parameterized).   The reason for the .[All] on the custom measures which get the work from N days ago is to deal with the scenarios where title or product unit or state etc had a different value on the prior date.  In effect we are saying:  give me the value of completed & remaining work from N days ago without regard to whether the value of those other fields match the filter we are applying to the current values (e.g. current state etc).
