SYS21 - Re: SYS21 - Re: SYS21 -  Using DRP orders as supply instead of demand

We are not running DRP here so I cannot test this out but I recall the
independent demand flag being active. A setting of scheduled orders and
demand orders should exclude DRP demand. I think the flag is at least
partially active. We used it once to keep a phantom item that was a sales
kit from seeing sales demand by having it look only at customer schedules
knowing that the part would never have any customer schedules.

It is tricky!
