Re: MPS - Customer Demand and General ECL Date Questions -- BPCS-L

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.

Hi Judi,

To clarify my question - should a lead time set on the
end item for an item
master (IIM) (not planning by facility) effect the MPS
planning for an MPS
item? What I'm seeing is that once I say an item is an
MPS item using the M
code on the Item Master (IIM) the system will not
consider the lead time
field in the item master. Instead, it looks solely at the
BOM and Router to
determine when a particular shop order must be started to
finish when
needed. Now if my BOM components of that end item have
lead times, the
system may be factoring that in - I didn't get that far
yet.

Paul, if I understand the question, lead time days is for
purchased as
well as manufactured items.  If you have different levels
in your BOM
need to enter the lead time for each level according to
actual time to
produce plus wait move and queue.  Judi Svoboda Ridewell

Questions


We're using BPCS V405CD(ptf2) and getting ready to begin
using MPS/MRP.
We're a discrete order job shop Die Cast manufacturer
(Order Policy H on
MPS
items) and will rely on Customer Orders to drive the MPS.

I see that it is the LRDTE field (Request Date) in ECL
(Order line file)
that feeds to the MPS.  The order entry department will
back the transit
(shipping) time from our shipping dock to the customer's
location and
enter
that date in the LRDTE field.

The challenge I have is that Shop order due dates, and
planned order due
dates as they appear in the MPS system are the same date
as the REQDATE.
This means that the system won't plan the shop orders to
be finished
till
some time during the day that the order is supposed to
ship out.

Is the REQDATE really meant to be a "Request to complete
manufacturing"
or a
"Request to Ship?"

If it is in fact, a request to complete manufacturing,
would I simply
back
the date up by one day. I'd love to hear from other BPCS
users as to how
their system is communicating customer requirements to
manufacturing's
MPS.

Another way I thought I could handle it is by adding a 1
day std move
time
to the last operation. But this would mean changing the
router of EVERY
Item
and every alternate router as well.

Lead time is for purchase order items, correct?

Also, how are the Schedule Ship Date LSDTE & Schedule
Receive Dates
LSCDT
used by the system? Should these be updated after an MPS
committment? If
so,
by whom?

Thank You!
