Hello, I have a question. I have data in my DSO like this:
Customer Calmonth ZCalmonth Quantity
101 201411 201406 10
101 201410 201406 20
101 201407 201406 30
101 201406 201406 8
101 201404 201406 9
102 201411 201409 10
102 201410 201409 12
102 201409 201409 20
102 201407 201409 6
102 201406 201409 9
102 201404 201409 10
My requirement is to add up the quantity based off of the value in ZCALMONTH, so for example: for customer 101, i want to show a record from beginning till 2014006 period which should be like this:
Customer Quantity
101 17 which is a made of 8+9
102 45 which is a made of 20+6+9+10
How can i do this at the query level please? Back-end can also be an option if this is not do able at query level.
Thanks.
