Weekly report

Hi :

In my selection screen, i have select option for date ( latest finish date of the work order S022-SSEDD.

But my report should display work orders for every week, say in my selection screen if i enter date range as 06/08/2007 to 07/08/2007, it should display work orders for every week separately.

At present , my report is displaying all the work orders together for the date range entered, but i want to display then for every week.

Thanks.
