Cross Tab columns

Hi,

I am stuck in the middle of my report design because of Record Selection criteria.

I am designing a Shipment details report for the customer delivers. How i can select only the last 3 delivery dates from the list of delivery dates ?

I want to use that last 3 dates as columns in the Cross-Tab.

Please help me...very urgent...thank a lot in advance.

I've only used it once or twice but there is a Group Sort Expert that allows you to select the TopN. You can look into that and see if it works.
