MPS for material

[Former Member]

Hi there ,

Do we always mark the finished goods for MPS...because as per my understanding MPS should run at the level where there is smallest number of product options ....

For instance in MTS scenerio it is the Finshed good but in Assy to order it will be in semi-finished sub -assy ...

Please suggest your views on the same ...

Hi,

You can use tcode MD41 - Single item multi level to run MPS material. So system plan upto raw material level.

Hi Dhrama ,

As per my understanding we go for MPS to plan the critical material first... freeze the plan & then go for the MRP to create the dependent requirement to the lowest level .... this will save us to change the enire plan to often ... if we multi level to run MPS material then this purpose will not be serve .... what do you suggest...??

Thanks & Regards

Hi,

Yes. For MPS material, we have to restrict MRP planning upto one level below the header level.

Remaining lower material we can plan with normal MRP procedures.

Hi Dhrama ,

Then what is the use of MD-41.... it more nothing but MRP run ...if we are planning all the levels in one go ...

Dear,

Normally MPS run before the MRP and during MPS system plans only those parts which are marked as MPS parts via MRP type. Here MRP plans single items (MPS items) and dependent requiremenst will be created for the parts which are just below the MPS assembly. It is advisable to run MPS a day before of the MRP run.

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

During normal MRP run system will not plan MPS parts again. only dependent assemblies and parts will be planned.

Hope clear to you.

Hi there ,

This is what is my query ... we have some imp material marked for MPS as per our previous discussion and we have other material for MRP run ......

In general we plan for just the next BOM level in MPS and the further levels are planned thru MRP (as we have discussed above) ...

Now when do we go for MD41... single item multi level ...because if we plan all the levels thru MPS then the purpose of MPS itself will be lost ....

Hi Kaushik,

We can say MD41 is used for both MPS and MRP, it will plan the materials up to last level of BOM.But during MD41 run you can stop the Planing upto your desired level.

If you want to restrict Planing upto 1 level of BOM then use MD42.

MD02 , MD03 will not serve for those materials which has MRP type M0.

Hi Dhaval ,

As per my understanding if we mark all the materials (header as well as all the components ) with MRP type PD & then run MD02 or mark them as M0 MRP type & run MD41.. there is no differrence ...

But we want to first plan the imp items followed by dependent component to make the planning stable ..

In which case (scenerio) then we go for MD41 ...

Dear,

First run MPS only with MRP type M0,M1,M2 and all and run with MD42 and then go for MRP in MD02 or MD03.

You can schedule MRP run , First run MPS items and then MRP in MDBT also.

Hope it will solve your problem.

Hi Kaushik,

If your Header Material has a MRP type M0 and BOM components are marked as a PD and if you want to run MRP upto last level of BOM in that case MD41 is useful.

It will more helpful in those cases were planing is based on confirmed requirement (Strategy 40 ) or sales order (MD50 also serves the same as MD41 only difference is it plans only for Sales order).

Now if you want to stop the Planing up to first level of BOM means only Planing is done for Header Material and Dependent requirement pass then in MRP 4 view of Header Material set Materials for dependent requirements are not planned.

Hi Dhaval & R.Brahmankar,

Thanks for your suggestions & update on the same ...

Dear,

Not all A type or all finish good comes under the MPS. The MPS material are those which consume critical resources and effect company profitability so it may be finish good or assembly.

If a MPS is run on a material, the necessary orders are planned at that level. Dependent requirements (if any) are placed on the next BOM level down, and then the process stops.

Main Idea : Master production scheduling (MPS) is a form of MRP that concentrates planning on the parts or products that have the great influence on company profits or which dominate the entire production process by taking critical resources. These items are marked as u2018Au2019 parts (MPS items) and are planned with extra attention. These items are selected for a separate MPS run that takes place before the MRP run. The MPS run is conducted without a BOM explosion so that the MRP controller can ensure that the Master schedule items (MSI) are correctly planned before the detailed MRP run takes place.

The master production schedule is a line on the master schedule grid that reflects the anticipated build schedule for those items assigned to the master scheduler. The master scheduler maintains this schedule, and in turn, it becomes a set of planning numbers that drives material requirements planning. It represents what the company plans to produce expressed in specific configurations, quantities, and dates. The master production schedule is not a sales item forecast that represents a statement of demand. The master production schedule must take into account the forecast, the production plan, and other important considerations such as backlog, availability of material, availability of capacity, and management policies and goals. Syn: master schedule.

Hope clear to you.

Hi there ,

I got the point ... in case of Assy to order scenerio where we are ready with sub assy & then we make the final assy based on the order ... in which level you suggest that we should run MPS keeping the capacity constraint in shadow for time being...... I vote for sub assy level...what is your suggestion ....

Dear,

Yes you can,

Consider a finished product A,which has a main assembly A1 & in this example we will take A1 for MPS,lets say for making A1 you need a special machine(Work center) & this machine is a critical resource for that company,So A1 is planned ahead in MPS to ensure that critical resource is efficiently utilised & at the same time A1 is also made on time,so MPS is run on A1 first before going for the MRP run(for the rest).As a result of MPS the necessary orders are planned at that level(in our case planned order for A1). Dependent requirements (if any) are placed on the next BOM level down, and then the process stops,Like wise if in your compnay if there are n products amoung which some products contibute a high profit then you can even take them afor MPS

Hope i have made you clear

Hi there ,

Now that we are ready with the planned order for A1 after MPS run ...the planing is done only till the next lower level of A1 in MPS..... so we will run the MRP for the further down materials to create the dependent requirement & also the MRP for the Finshed product .....

I guess that I am correct ..Please advice

Dear,

Yes you are right go ahead.

Or you can plan all MRP material in MPS also with MD40 whith active tick mark for MRP material.
