Earliest date based keyed on test code, student ID

[Rich]

(I'm sure this calc is here somewhere in the forum but I couldn't find it, so my apologies.)

I have a solution that captures test codes and the dates students take those tests, but what I want to do is flag the earliest date a student took a specific test with the phrase, "First Attempt".

I included a set of sample records for a specific student with this post. As you can see, there are three instances of TestCode 0061 but I want the flag to appear in the earliest-dated record, 07-25-2009.

I figure it will require a separate T.O.- keyed on StudentID and TestCode--and that somehow it's a comparison of one-to-many, but that's about as far as I got; I tried using the MIN command but got nowhere, so if you could steer me down the right path, I'd appreciate it. Thanks!

Oops, just figured it out:

Case ( Min ( PRAXIS_CHILD.FirstAttempt::TestDate__lxd ) = TestDate__lxd ; "First Attempt" ; "" )

 

I put the local table after MIN instead of the other T.O. *blush*

Little concerned about your structure, see if this helps.

Many thanks, Steve! That will certainly come in use with any future reports--it's a keeper.
