Hi Allyn, although it's theoretically possible, I have not been able to find an efficient weekly solution. The problem is that a summarized version of the transaction detail file would have to be setup in a container, in order to pull by week number. And, week number would depend on how you or your client define the weeks within a year (which can vary). I have also heard of people pulling the Transaction Detail as a Subreport of your main report and using a pivot table to get the weekly information. You might try searching
