MPS run, planned orders were created for all levels ?

[Former Member]

Hello PP members

I ran a small scenario

material MRP Type Low Level SG M/T Type

A M0 000 40 FERT

B PD 001 40 HALB

c PD 002 10 ROH

Maintained PIRs(MD61) for material A, and ran MD41( Single Item Multi level Planning)

As material A is an MPS item, I was expecting that it should create planned orders only for material A, but in this MPS run it created planned orders for material B & C. (Looked into MD04, where I see planned orders were created

for all the levels)

As per the MPS run, it will plan only for one level of BOM (in this scenario for material A)

Any suggestions, why planned orders were created for material B & C

please clarify

Just check

System must have created a dependent requirement planned order and not the planned order for requirement you put in demand management for B and C

i.e. if you enter a demand in MD61 for B and C, run the transaction, system will not consider this requirement during MPS run. MPS run will consider the requirement if the requirement for the child is comming from parement where parent is MPS item.

Hence you need to run MRPm for B amd C if teh requirement(not dependdent requirement from A) is to be considered.

I hope you are clear

Hi,

For MPS run you have used tcode MD41. It is a single item multi level planning run.

MPS plan for below one level only. But this is the tcode provided for multi level run.

For single item single level run use tcode MD42.

In your scenario, system created palnned order upto ROH level, eventhough HALB & ROH mrp types are PD.

But with tcode MD02 or MD03, can not run MRP type M0 and series.

Dharma

thank you for your reply

How do we justify the statement MPS run plans for single level BOM

what I see from MD41 run, it is planning for all levels of BOM

Please clarify

Running MPS with MD42 itself signifies that MPS is run for single item single level

Its like running MD03 in case of normal MRP

Hope u r clarified
