RE: MPS - Customer Demand and General ECL Date Questions

Hi Jim,

Of course I remember you from the NorthEast BPCS User groups. I hope all is
well with you!!

You said, "BPCS4.05 CD MPS & MRP uses LRDTE from ECL
minus lead time in days from either the IIM
or CIC ( if planning by facility)to calculate a suggested
release (start) date."

I don't see the system using the lead time in days and that's the heart of
my dillemma. So for example, suppose I have a customer requirement (LRDTE)
for 2/21/2003 (a Friday) and a shop order open that is going to take only 3
days to run but I have a due date set to 2/28/2003. When MRP500 is run, the
action message is to reschedule the shop order to be due on 2/21/2003. I
really need the order to be due on 2/20/2003 so it can ship on 2/21. I've
put different days in the lead time field of the end item and it still tells
me the shop order should be made due on the LRDTE field's date.

Thanks,

Paul

Hi Paul !
BPCS4.05 CD MPS & MRP uses LRDTE from ECL
minus lead time in days from either the IIM
or CIC ( if planning by facility)to calculate a suggested
release (start) date.
SFC500, however, does not give a hoot about lead times.
It takes the due date minus appropriate run, setup,
machine, move & queue to backward schedule the order.
OR it takes start date plus those hours & days to
calculate
due date.
That is why it is so important to have lead times be
as "realistic" as your routing times.
