Dear all,
I have searched in depth through the forums for an answer to this but all running sum posts do not quite answer my problem.
I have a table ("tbl_idq_all") with a text field for product codes ("scode"), a date field (dd/mm/yyyy) and a quantity field ("po_qty"). This table therefore holds future receipts of stock for products.
What I am having trouble doing is create a running total of [po_qty] based on [scode] and [Date].
A good example is stock code 10254. This has a quantity of 40,032 arriving 01/06/2013 and a quantity of 30,096 arriving 01/09/2013.
Therefore the running totals should read:
scode | Date | po_qty | RunningTotal
10254 | 01/06/2013 | 40032 | 40032
10254 | 01/09/2013 | 30096 | 70128
As you can see from the attached DB I have 70128 repeated twice in the RunningTotal column.
And help would be very gratefully received!
Nick
