query on the MRP Strategy 40 Vs 10 : Dependent Demand

0 Kudos
139

Hi All,

I have one query on the MRP Strategy 40 Vs 10

Suppose we have common Dependent Demand for both Finished Good- Material X and Material Y.

I have initial PIR

Material X - PIR (independent)1000

Material Y - PIR (independent)1000

Sales Order comes for Qty- 2000 for Material B

If we use MRP Strategy 10

After MRP run- 10 Strategy will create Dependent Demand for 2,000

If we use MRP Strategy 40

After MRP run- 40 Strategy will create Dependent Demand for how much? and why?

Will I end up with more Dependent demand for strategy 10 or strategy 40

Thanks In Advance

Arun

Hi,

You forget to mention what is the relation between materialX, Y, B - w/o this your question makes no sense.

In case of strategy 40 & 10 you plan at FG (final assembly level). Why do you input PIRs for materialX & materialY???

If you use strategy 40 for materialB > SO for materialB will be considered as requirement and and may consume existing PIRs (PIR for materialB). Based on stock level of materialB, requirements, POs, PrdOrds, etc - so based on WHOLE PLANNING SITUATION - SAP will create procurement proposals. Dependent requirements can be calculated if you know the whole planning situation of materialB.

If you use strategy10 for materialB > SO of materialB won't be considered.

Please specify your question and describe better what you want. Please also check SAP online help where it is explained even through sample scenarios how strategy 40 & 10 work.

Sorry..Writing Material B was an error.Sales Order comes for Qty- 2000 for Material Y

Relation between Finished Good- Material X and Material Y is that

You have Raw MAterial A

Process Stage 1- Semi Finished MAterial A1

Process Stage 2- Semi Finished MAterial A2

Process Stage 3-

Semi Finished MAterial A2 + Packing1 = Finished Good- Material X

Semi Finished MAterial A2 + Packing2 = Finished Good- Material Y

You Have BOM in System. MRP explodes independent demand into dependent demand.

Now Dependent demand is Semi Finished MAterial A2.I want to know how this Dependent demand will behave w.r.t different Strategy 10 and 40. Now i have set the context..i have pasting my corrected question again.

I have one query on the MRP Strategy 40 Vs 10

Suppose we have common Dependent Demand for both Finished Good- Material X and Material Y.

I have initial PIR

Material X - PIR (independent)1000

Material Y - PIR (independent)1000

Hi,

1. You did not mention anything about planning situation (stock levels, etc) - I asume all the stock levels are 0 and there's no transactional data for the mentioned goods.

2. You forgot to mention for which material planning strategy 40 and 10 set. I assume for materialY.

3. I don't understand why you are mentioning materialX??? What is the purpose of it as far as your question is concerned?

4. What are about other master data settings (e.g. forward/backward consumption), dates, etc???

One possible answer (you get procurement proposals after MRP run):

A) MaterialY with strategy 40

MaterialX

Requirement: 1000 (PIR)

Procurement proposal: 1000 (PldOrd)

MaterialY

Requirement: 1000 (PIR) + 2000 (SO) = 2000 (based on forward/backward consumption maintained in material master)

Procurement proposal: 2000 (PldOrd)

MaterialA

Requirement: 1000 (DepReq - coming from materialX) + 2000 (DepReq - coming from materialY)

Procurement proposal: 3000 (PldOrd)

B) MaterialY with strategy 10

MaterialX

Requirement: 1000 (PIR)

Procurement proposal: 1000 (PldOrd)

MaterialY

Requirement: 1000 (PIR) + 2000 (SO) = 1000 (as I mentioned SOs are not considered in strategy 10)

Procurement proposal: 1000 (PldOrd)

MaterialA

Requirement: 1000 (DepReq - coming from materialX) + 1000 (DepReq - coming from materialY)

Procurement proposal: 2000 (PldOrd)

Based on your stock level, dates of PIR and SO, open PrdOrds, POs, etc you may get other figures.

You should test in your sandbox system how it works.
