Re: demand control for MRP planning - orders vs forecast 1.MRP Method 405 CD

Thankyou.
You have identified for me which of the many SYS800 screens, and which
elements on that screen, are relevant to managing MRP methods, and how
method # 1 works.

If we have customer order for 50, forecast for 250, method 1 will plan 250,
but I think we need method 2 which will plan 300, where we use forecast to
plan delivery of raw materials that have 65+ days lead time, to be ready for
customer orders placed with no more than 20 days lead time.

Right now our forecast orders are supposed to be entered with due date that
is far enough out to cover the lead times. We are looking into changes in
how we do things for a variety of reasons related to trying to reduce
clerical time to get the job done, and lower risk of mind-numbing moving due
dates on forecasts without rethinking what makes sense, as we suffer from
the economy.

I need to think about whether it makes sense to have different method code
for before / after our 20 days time fence.

Some answers can lead to more questions.

Do MRP files contain some code showing where an exploded BOM requirement
came from: customer order; MRP100 forecast; minimum balance?

Set the defaults on SYS800 MRP System Parameters screen. (see below). You
can then override it for each item/fac combination if you are set up for
multi facility or each item if planning globally.

Repetitive Other


Demand Code to be used before the Time Fence 1 4 (1,2,3,4)


Time Fence (Periods for Repetitive, Days for Other) 7 30


Demand Code to be used after the Time Fence 1 1 (1,2,3,4)



Orders consume forecast basically takes the greater of orders and forecast

Eg. Orders for period 1 = 50

Forecast for period 1 = 75

Plan for 75



You can affect the impact differently before and after the time fence.

In the example above, we use orders only for the first 7 days, then the
greater of the 2 after.

We want to start using MRP100 forecasting, which I looked into years ago,

but now I forget some nuances.



MRP300 says our method is that "Orders Consume Forecast"



We just want to be sure that both orders and forecast will dictate

requirements.



Help claims that method is set in SYS800 parameters, but I can't find the

screen that has this.



Code Description



1 Greater of forecasts or customer orders

(consumption of the forecast by demand)



2 Sum of (customer) orders and forecasts

(augmenting demand)



3 Forecasts order only

(anticipating demand)



4 Customer orders only



I think method 2 makes more sense vs. our current needs.
