Hi,

Please check following things

1.Planned delivery time in material master record.

2.Check the stock availability :If sufficient stock is available then system will not prompt for the procurement.

3.Along with this check your lot size .

Dear Amit,

I had checked in the QA and PROD system .But in QA stock of the material is enough so i can understand that in this case MRP wont prompt to buy for the material.But when i checked in prod system there is zero stock of this material so why system doesnot give any promt to buy ?

And i have checked the things you have mentioned that

Pl. del time is 63 days, lot size is MB(Monthly lot size),

Kindly tell me some clues ASAP.

Thanks,

Narayan

Hi,

Do the below checks,

1. Check in MD21 for this material - plant combination if an entry exists in Planning file (if no entry exits, create an entry via MD20)

2. Check if MRP dep. rqmts field value is blank for the immediate parent of this material.

3. Ensure that bulk mtl indicator is not ticked in mtl master or in BOM

4. In MMBE, check if there is any stock in QC or in any other segment.

5. If the above does not help, then paste the values of your av. checking rule ZC.

Check & revert.

Regards,

Vivek

Dear Vivek,

I had checked all the things you have mentioned.

Planning file entries are not maintained for this material.

Bulk material indicator is not ticked.

I had checked in opjj values for ZC,there are only 4 check boxes are ticked i.e. include safety stock,stock in transfer,and incl. quality insp. stock and check w/0 RLT.

And also hi all,

The requirement was there on the 25.03. And user ran MRP on the 30.03 but there is no PR genereated. Only after they ran it the second time in 02.04 then the PR is genereated. Question is why on the 30.03 there is no PR generated for this item.

SO PLEASE TELL ME THE REASON.

Thanks,

Narayan

Hi,

Please create a planning file entry for this material - plant combination using MD20.

After creating the entry, re-run MRP & the system should put out a procurement proposal if there is no stock.

Check & revert if it resolves the issue.

Vivek

For MRP run to consider a material, initial pre-requisites the MRP type should be relevant for MRP eg: PD, then a planning file entry should exist.

In this case as you say there is no planning file entry, system will not consider the same. Hope it clarifies your query.

Dear Vivek,

My question is that why the system generates PR on date 02.04. and why not on 30.03.Because when we ran MRP on 02.04 then Planning file entries are not there then also it generates PR.

so my question is that if the problem is with planning file entries then it would have not also genetares the PR on 02.04 ?

So please tell me why this is so?

Thanks,

Narayan

Can you let us know how you ran MRP on 30th & on 2nd?

Was it a plant run on 30th i.e. via MD01 or MDBT & on 2nd was it via MD02 or MD03?

Hi Narayan,

Which T.Codes you have used to run MRP on 30.03 and 02.04.

See Entry in Planning File is must needed when you runs the Total MRP or Total MPS.Its not required when you runs the MRP through Single Item Mulitlevel or Single Item single level.(MD02/MD03/MD41/MD42)

Hello,

We delete old forecast and uploads new forecast weekly.

Forecast consumption logic is from 7 days in the past until 7 days in the future.

As far as I know, forecast reduction on next week's(Wk19) forecast resulting from current week's(Wk18) shipment will still reduce fresh forecast for next week(Wk19).

Is my understanding correct?

If we don't want next weeks' (Wk19) forecast to be reduced after the fresh forecast is uploaded, should foreward forecast consumption period be set zero?

Can you suggest options we can look at and the best one we should consider first?

Thanks a lot in advance!

best regards,

Thanks DB49 for checking this.

There needs to be at least reqmnt of safety stock for the system to trigger net reqmnt and create procurement proposal, if there is shortage.

Narayan,

What was the requirement date for material? I was not able to see that data in your post.

Hello Narayan,

Is there requirement for this material?

[Former Member]

The question doesn have enough details to understand your query...

But I assume that the System is not giving you message about when to procure this item..

If so, Please check whether Planned delivery time is properly mentioned in the material master..

And also check for the stock of the material. If the material is sufficient in stock then MRP wont ask you to buy this material..

Hope this clarifies..

Dear Karthik,

Actually planned delivery time is maintained 63 days and i checked in MMBE there is no stock for this material.And user wants that why the system doesnot prompts that you have to buy this material ?

So kindly give some hints.

Thanks,

So it seems that MRP has considered the Quality stock..

If you don want Quality stock to be consuderd, Just go to OPJJ and exclude the quality stock.. and rerun MRP by giving planning mode Delete and recreate planning data..
