MRP Run - Pur.req. not deleted

[former_member207022]

Hi

I created production order,contains components ALF. Later on i have changed component as CGB insted of ALF. In stock/req. list i alreadh have the PR for ALFis there. When i change the component as CGB and when i rerun using MD02 header lever the MRP my ALF purchase req. is still there, it is not deleting. Where is the problem?

But when i run the MRP only for the component ALF, it is deleting?

Please clarify.

Dear,

If PR are firm * mark appear in front of purchase requisation in MD04 then it will not get delete by MRP run you need to delete manually.

Can you provide a lil more details, like the MRP parameters of this material, also when you say change the material, how did you do this change?

[Former Member · Accepted solution]

If the req is fixed, signified by a * in MD04, then it will not delete through MRP.

Thanks.

There is no firming indicator ** appear.

I explaing again, Initially i created prod. order through MRP (Planned order to prod.order conviersion), later that i have changed the component. So now 1st component ALF has no reservation for any header material. If i run MRP, it is not deleting.

I tried with planning mode 3 and also no firming indiacator is there.

Dear,

For that material run MRP in MD02 lor MD03 that you want to delete with planning mode 3 and check the result.

When i run the MRP for that raw material level, it is deleting. But when i go for MRP Run using MD01 for that plant level, it is not happening. Because in MD01 we are running MRP throughout the plant level, so no req. for that raw material and also no firming indicator also.

Hi,

I am sure your well aware under what criteria a proposal will be deleted & when it would not be. All i can suggest is, study through the parameters of your MRP in material master & also look thru' the requirements. Alternatively if you can upload the screenshot, i can have a look to see if i could be of any further help in troubleshooting.

Dear vivek,

sorry for late reply. I have prod. order with component A and PR created. Now i have changed the component as B in prod. order insted of A, but not changed in BOM. But still the same demand.

When i Rerun the MRP using MD02 -MRP parameters -Processing key - NETCH,1 3 1 3 ,scheduling - 2.

Process control parameters - All tick mark except simulation mode.

Now i am getting the result of Component B PR created. that is fine. But i have the old PR for component A, but still it is there, it is not deleting.

Material master MRP parameters are MRP type - PD, Lot size - MB, Ind/coll.indicator - 2

Please suggest.

First click on the PR & check for which item it is pegged in MD04

Also can you check & confirm, if there is any other need for Mtl - A, check if it has any safety stock req. if any?

Also check in RESB table for this material if you find any reservations coming in.

Await your inputs.

Regards,

Vivek

Dear vivek,

I checked the PR, the item has no pegged requirement. There is no requirement for A component. We dont have any saftey stock req.

My question is if the component has no pegged req. so how the system will derive it? whether it will delete the PR of component A or not?

But if i run the MRP using MD02 for that component only not for header level, it is deleting the PR.

Hi Ganesh,

Let me simulate at my end & revert. But find it quite interesting, anyways will check.

Have you placed a PIR for the top parent? Can you let me know how the demand is generated for the top parent for which you have created the order?

Dear vivek,

Parent is there in demand, I created demand through MD61 only.

[Former Member · Accepted solution]

Hi Ganesh,

I guess that should answer the query, isnt it?

I simulated the exact same scenario & notice what your mentioning.

When a need is placed at top parent level i.e. PIR, the MRP run will explode the BOM, so it generates a P-Req.

In this case you have deleted the component in the production order & not in the BOM, so when you run a multi-level at Parent level it will generate the need.

But when you run at the component level, your planning at that level & below it.

I hope your clear.

Vivek

Dear vivek,

Thanks. so as per standard SAP, it wont delete the PR for my component A which was deleted in prod. order and exist in BOM. Is it so

[Former Member · Accepted solution]

Hi Ganesh,

Yes, because when BOM explodes it finds this component. The deletion is done at order level & not at BOM level. It checks for other materials & it finds that the need is being met, so does not generate any new proposals.

Hope it was helpful.

Ok thaks vivek.

Hi,

Boss you have change the Component itself.And now if you rerun the MRP in both Planing 2 or 3 system explose the BOM and planned for only those materials which are then in BOM.But in your case you have already removed that AFV material from the BOM then how system will re plan for this component.So you have to manage it by individual planning run MD03.

Dhaval
