Re: MRP and MLI

Buffering with master schedule would be good, normal practice.  And in most cases we have MLI items with forecast code 2 (generate but don't create requirements) and plan customer orders = 1 (plan beyond current MRP date).  Normally I recommend that they plan customer orders beyond the release or review horizons (2,3) but in this case they have "drop" in orders to rush and they can't change the culture that fast, so they keep a large amount of excess capacity and inventory around to accommodate a "rush" order.

there are some very low volume items with un-plannable demand that they want MRP to see the customer order at lead time.  But (and this is the truly amazing part to me) unless the item is MLI it will not, under any circumstances, create MRP demand.

I'm just trying to confirm if anyone has known of this, or if anyone has MRP generating MRP requirements from customer orders that are NOT MLI.

Thanks all.  Very interesting
