example of what I have:
item - transactionNO - Qty - Balance - date
X - Receive 123 - 10 - 20 - 1-1-2001
X - Receive 456 - 10 - 20 - 2-1-2001
on "receive 123" I need the balance to be "10 only" which is the balance at the date of the transaction...
I created a report to show stock level and transactions. there are date, transaction, quantity and balance fields. the balance field show the total balance of the item at the moment. what I need is to show the balance at the transaction date.
