Question:

Dear fans,
I've got one issue when I run MRP for subcontracting.
Could you give me suggestion on this as soon as possible? Thanks!
Scenario:
We are using SAP 4.6C.
We have two plants in the system, one for our own factory (plant A), another is a virtual plant (Plant B))for subcontractor in the system, some components are directly supplied from vendor to subcontractor while the other material are transported from our own plant. We are going to run MRP for both plants.
We create MRP area for subcontractor (vendor MRP area) and Assign to material master data.
The BOM for subcontracting has two levels, and the subcontract fee is calculated based on weight of material. The final FG has multiple unpacked products (semi-FG). We need to pay the service cost for either final FG and the (semi-FG) with different price. Hence, PRs (for subcontract from same subcontractor) for semi-FG are required in MRP run. For the components(raw and packs), PR will be converted to standard PO to vendor or STO for stock transport from our own plant.
For all the components, we have create source list (and some have quota arrangement) and click the indicator "1"for "MRP relevant".
For the components that provided directly from third party(out vendor) to subcontractor, in "MRP 1' view, we assign MRP area of subcontractor to the master data.
For the components that provided from our own stock (STO), we use special procurement type 41 (copy from " 40 Stock transfer (proc.from alter.plant") to link the MRP from the plant B to the plant B.
Result:
After MRP run, we can get the PR with proper quantity(requirement), which exploded based on the BOM.
For the material provided from our own stock, the requirement can be automatic transferred from subcontractor plant (Plant B)to our own plant(supplying plant, Plant B). All the PR in our own plant (Plant A), which includes the requirement transferred from (Plant B), the vendor can be automatically assigned by the system according to source list for plant A.
The supplying plant can be assigned properly to PR for STO according to source list in Plant B.
But the materials (components) that directly provided by third party(our vendor) to subcontractor, requisition can be only generated without any vendor assigned in PR (Plant B), even though the vendor is fixed in source list (Plant B) or 100% in quota arrangement(Plant B) !
Questions:
1. Is it possible to have the system assign the vendor automatically to the PR (according to source list), which for the materials (components) that directly provided by third party(our vendor) to subcontractor? How to realize this function?
2. Why in the source of list, we cannot change the MRP area to the subcontract vendor MRP area (it is default as plant MRP area)? Is it the reason why the vendor cannot be assigned to PR , which for the materials (components) that directly provided by third party(our vendor) to subcontractor?
Thanks!

Hi Fans,
Any comment on my problem??? Urgent!...
By the way, I have tried other way: select SC indicator in Contract with delivery address for subcontractor. And I do not maintain MRP Area in components' master data, which is external procurement! But the vendor still cannot be assigned automatically in PR.

Answer:
Hi BY,
My preliminary understanding from your detailed explanation of your business process was that the utilization of Plant B in your subcontract process has much complicated your technical settings. Of course, further clarification shall be made to come up to possible solution for your outstanding problem. Therefore, will it be possible that we can discuss off-line and I will post my further recommendation to this posting eventually so that we can have final solution for this. If this is the case, then would you mind contacting me via MSN Messenger? My account is tranlamha@hotmail.com
and we will talk about it in details.
Cheers,
