PO no check in a Sales Order
I've a Sales Order, for the doc type, I've activated the PO check/duplicate PO check in VOV8. However, does the sys check this PO no we enter in the SO, against something?
Does it have to do anything about the Sold to Party we use while creating the SO? 'My client wants to check, if the PO check can be set at SH level rather than SP level.' This confuses me, as I never knew that the PO is checked against a SP or something.. plz share..
Fast response will be highly appreciated....
