[Help] - MD01, MD02 and Planed Orders

[Former Member]

Hello SAP gurus, I have a problem with transactions MD01, MD02 and the Planed Orders.

Scenario:

I have a IndReq of quantity 10 UN for a material. When I run MRP (MD01) with Scheduling 2, SAP creates a Planed Order of quantity 10 UN and create capacity requirement in the work center.

If I run MRP again in MD01 but with scheduling 1, SAP does nothing!!! - This is my problem...

But, if I run mrp again in MD02 for material with scheduling 1, SAP deletes the capacity requirement for the work center...

Note that, I never change the IndReq.

Can someone help me with this?

Thanks in advance,

Hi,

If you use the Scheduling 1, Then the inhouse production time will be taken from the material master( What ever you maintain in the MRP 2 View Scheduling). And if you use scheduling 2, Then it will take the time from the work center and it will create capacity planning also.

Both MD01, MD02 scheduling view will have the same effect.

Hope it wil be helpful.

Vijay.

Hello, and thanks for the replies...

The point is, I am running MRP in MD01 and MD02 with the same parameters but transaction MD01 wont afect the material and MD02 recreates all planed orders!!!

I don't know why this is happening???

Hi Adelmo,

For any material to be planned by MRP, Planning file entry is a Must.PLease check for the Planning file entry in MD12, that should tell you why it is happening at the time of MD02 and Not in MD01.

Hello Ratan,

Planing file entry exits for the material. How to know witch is MD01 or MD02?

When we run MRP the system checks the planning file entry check for the material and proceeds for planning if the entry exists.once planned, the planning file entry will not be there till a MRP relevant change is there for that material. this is to reduce the system load.

in your case first time you run MD01, after that the Planning file entry should not be there.

check the planning file entry before the next two runs of MD01 and Md02. let us know what is that entry?

Hi,

With MD01, irrespective of planning file entries all the materials will be planned.

Please check whether your material is created with in the scope of planning or in the plant specified in the MD01 initial screen.

If you want to check the planning file entries the TCODE is MD21

Try with planning mode 3 in MD01.

Hope this may be helpful to you.

Hi Prasad,

MD01 or MD02, we are running the same Programe,

MD01 is for a total Plant or a group of plants, so the number of materials are going to be huge.so the planning file entry makes more sense here rather than at MD02 , where only one material with its Componenets are being planned.

Irrespective of the Transaction, when we run the MRP , checking the planning file entry makes sense as it optmises the system load.

Hi Silva,

In MD02 t-code are you using planning mode parameter as a 3(delete and recreate planning data).Please use 1(Adapt planning data)
