Rolling Calculation using ACROSS

I could use a little help with a problem. I am creating a report of orders accross dates. For example:

__________Dates
__________6/23/2005_________7/1/2005
On Hand___Orders___+ or -____Orders____+ or -

7,500_____5,600____1,900_____2,500_____(600)

The problem is that I need to calculate the excess or shortage after each date. In otherwords, Excess = Excess@PrevDate - Orders@CurrentDate. I think I will have to use some kind of column based calculation but I am not sure how to go about it. Any help would be appreciated.

Thanks,

Brian

PS. Sorry about the underscores. Only way I knew to line up example

If you are using FRL, then there is column based calculations, but I think in your case using LAST would be simpler. If this is actually with some other BY, then the Calculation for SEQ would be IF byfield EQ LAST byfield THEN SEQ + 1 ELSE 1;
Here's the code I used to get what you asked for:
TABLE FILE fn
SUM COMPUTE QTY_ON_HAND/I6 = 7500;
SUM ORDER
COMPUTE SEQ/I5 = LAST SEQ + 1; NOPRINT
COMPUTE QTY1/I6B = IF SEQ EQ 1 THEN QTY_ON_HAND - ORDER ELSE LAST QTY1 - ORDER; AS '+ OR -'
ACROSS DATE
END

Thanks!!!!!

That works beautifully. I did not know that there was a LAST keyword. That's a handy keyword to know.

Ok guys,

one more issue on this one. Like the previous post stated, the rolling calc works great. The complaint now from my users is that if a row has no orders for a date that is on another row on the across, the rolling calculation does not show. They would like to see a zero for orders column and the corresponding compute so that the totals for the report will include the overage or shortage for the date.

Thanks

Brian

You need to supply the missing instances with zeros, before doing your TABLE with ACROSS.

The general approach:
Generate a full cartesian product of all row and column keys (products and dates); then use MATCH FILE to merge in the missing instances; and then you're ready to apply the ACROSS.

Or, if you know the range of values you want to display ... ACROSS COLUMNS 'date_value1' AND 'date_value2' AND ...
