ReportWe've got a product with lead time of 6 days + 3 days transportation margin.
We've setup a weekly sales forecast of 100 pcs / week -> this generates a weekly planned purchase order for this product, which is good.
We've set the positive days to 365, the negative days to 6. If we put the negative days to more than 6 days, master planning isn't going to increase the quantity of the planned purchase order in case the actual demand is bigger than the forecast, because it tries to "tackle" the demond with the other future planned orders created by the forecast.
so far no problem.
The problem is when the vendor of that product closes for a week. (via the calendar of the vendor). Master planning creates a planned order correctly taking into account the holiday period of the vendor (the delivery date is one week later), but when we firm that order, MRP just keep creating a new planned order for that same day. We can firm that 2nd order and MRP just proposes a third planned order etc.
The reason why MRP proposes that 2nd (and third...) planned order is clear to me, the product doesn't arrive in time, because the vendor is closed. And our firmed order is deliverd too much in the future (because of only 6 negative days).
The same problem actually occurs if we don't use a calendar on the vendor, but the vendor confirms the purchase order with a much later delivery date.
Is there a way to get around this?
