I have data in a form similar to this:

Date;SKU;Production
Date1;SKU1;Production1
Date2;SKU2;Production2

The production field is just a number, the date is a date, and the SKU is a
string.

I need to find the max average production number for each unique SKU that
was produced in a given month. There are numerous SKUs and numerous dates
that they were produced over a range of months. Some example data below:

5/6/06;010102/1;5600
5/7/06;010102/1;4000
6/2/06;010102/1;3000
6/4/06;010102/1;4000
3/2/06;03531/1;400
3/6/06;03531/1;200
4/1/06;03531/1;500

So for this data I would need excel to spit out on a seperate sheet:

010102/1;4800
03531/1;500

4800 is the average production for the month of May for SKU 010102/1 and for
June for SKU 010102/1 the avg production was 3500, but the max production in
a month for that sku was 4800 so that was put on the sheet.

Any help would be greatly appreciated. Thanks.
