Multiple PR's generating for same material after MRP

[Former Member]

Hi Guru's,

As per my business scenario, i am creating project with WBSE, Activities and BOM.

By using the reference points, i am transferring the BOM to Project, then executing MRP run.

But after MRP run i found that multiple PR's generated for the same Material.

Please find my BOM structure

BOM-->Assembly + raw material

Assembly is consists of

Sub-Assembly+ 2 raw materials

Sub-Assembly consists of

1 Raw Material.

as per this i should have 4 PR's after MRP but system is generating 8 PR's.

Please tell me where i am doing wrong

Hi Rao,

Have you tried to execute the Project by adding the component manually and do MRP run, check whether multiple PR's are created.

If not, then we need to concentrate on settings related to BOM...

Let us know your findings after you tried this scenario.

Hi Rao,

You need to contact MM team, since there is a problem in MRP setting.

Check OMDV, whether this resovles your issue.

Also check in "Define Profiles for Bill Of Material Transfer" under Project System configuration

Hi,

I find the reason why it is creating the multiple PR's for the same component.

It is because of the BOM status. Please find the attached scree shots for the BOM structure and BOM status.

As per my requirement the Planned Orders should be created for "BOM" and "Assembly" and 3 PR's should be generated for Components.

Initially i maintained BOM status as "4" for "BOM" due to that system is exploded the BOM twice i.e., for "BOM" and "Assembly" and generated PR's twice and two planned orders for "BOM" and "Assembly" along with their components.

Now to avoid the duplicates PR generation, i have maintained BOM Status as "5" for "BOM"and run MRP.

This time system is generated 3 PR's and 2 Planned Orders.

As per as PR's is concerned there is no issue. Coming to the Planned Orders there is a issue that, the components are not copied into order which is generated against "BOM" (BOM Status-5) and components are copied into order which is created against "Assembly"(BOM tatus-4)

But as per my requirement, the components should copied in both the orders.

So please tell where is the wrong in this..

Hi Rao,

I dont think the problem is due to the BOM status 4, since SAP recommends to have all the boxes ticked for BOM Status 1. Thats what we are using it.

Also BOM status 5 is without MRP checked, so i feel the components are not copied.

There are lot of other parameters related to MRP is involved, i am not sure whether others are correct, you need to consult a PP or MM consultant.

On checking the BOM Status, there is no issue with BOM Status 4.

May be BOM status 1 is standard as per SAP, try to check all for BOM status 1, change the BOM components to BOM Status 1 and check it how it works...

Thanks

Hi,

I am not sure but I think this is something related to Lot Size being maintained in Material Master.

Check Lot size at MRP1 tab for your materials in MM02. Change it to MB if it is something else. Check in your development/quality client.

Not sure if this will help you. Please also wait for other experts to comment on this.
