Dear both,
did that really work?
as far as I know the PP/DS heuristic runs in the receiving location (= your production plant), and considers lot sizes from taht Mat-Loc-combination. If you now create one Mat-Loc-combination for each vendor (which is the delivering site), the heuristic will
a) create a stock transfer order (instead of a 'normal' purchase requisition)
b) not consider minimum/maximum lot size quantites or round value from these new vendor locations
Is there any other solution?
