SAP MM sub contract process?

[Former Member]

Hi Colleagues,

I am at a aero project at which we are looking for a solution that looks not to be available in Sap ECC5 MM. Is the below scenario possible within MM  please?

1. We send our supplier a list of materials that need to make an assembly and also the top level header part number for assembly itself. We will do this by interfacing supplier delivery scheduling lines.

2. The supplier will receive message and take list of materials to then construct assembly part for us at their premises. The low level materials are not issued to them by us as they belong and sit in supplier own stock in there warehouse.

3. Supplier sends us the assembled part which we book into our stock, but will not send us on delivery message (maybe asn)which components make up assembled part they send us.

4.We pay invoice for assembled part.

What is required is for us to send them list of components in schedule lines but we book in assembly (we will not actually issue them components like standard MM subcontract process). The issue I see is that we would have many del schedule lines which are open as they are not booked in but only assembled part. Also, do need to consider any BOM type?

In aero defense industry in far east,this model looks to be essential and new practice when working with many big suppliers.

Your views on this would help please.

Thank you.

Poonam,

I am a bit confused.

1. We send our supplier a list of materials that need to make an assembly and also the top level header part number for assembly itself. We will do this by interfacing supplier delivery scheduling lines.

Exactly what is the source of these 'supplier delivery scheduling lines'?  Are you getting these from your subcon?  Or, are you somehow generating these 'in house'?

Hello DB49,

I would be wanting to generate them in house with MRP. The vendors want to know the from us the top level part (assembly code) and also the individual materials that make the assembly.

Poonam,

So, it sounds to me like you are not going to be planning the components (since you have no visibility of the Subcon's lower level Materials on hand, nor his open Purchase orders, nor his demand for these components that is generated from customers other than you).

It really sounds like all you can do is to send him a list of your exploded demands for the Purchase orders that you send to him. Don't attempt to send schedule lines, which represent future supply.  From what you have described so far, you don't have enough information about his internal affairs to give him any meaningful supply schedules.

This listing doesn't have to be anything more complex than a simple query or z report.

Best Regards,
