constraint the quantity ordered against the Purchase Requisition
I have problem in Purchase Requisition, when I have done one PR doc. I put the 200 as the quantity. and when I'm doing the PO I can put the quantity 400, without error message. I also can create 2 PO with reference to the same PR, so for example PR quantity is 200 , the qty for first PO is 200, and The quantity for second PO is also 200. now , this condition is acceptable in my system. what should I do to avoid these kind of conditions, therefore no over-delivery, or mistake in ordering.
Hope to see ur feedback soon
