Subcontracting Process Vendor Side

[LucianoA]

Dear Colleagues, hope this message finds you fine and well.

Would you mind helping me comprehend the subcontracting process, by the Vendor point of view?
How does SAP manage this process?

Standard Subcontracting process rules the process considering the Client/Customer point of view, therefore it assembly the solution to suport how the Client/Customer post subcontracted goods to a Vendor, granting full control of its own stock out of the facility instalations. This is not what we're exploring at this moment.

The situation I'm exposing here it the opposite side. Considering I'm the Vendor, I'll process this subcontracted goods receipt, assembly/use this material in order to produce a final product, than sell the final product to the Client that has consigned me his material, and I need to symbolic return the consigned material + charge effectively the products I'm selling + charge the overhead costs to assembly the consigned material to the main final product.

Situation# How to manage subcontract process by the Vendor point of view (me as a Vendor)?

Brazilian Legal Requirements# 'Bloco K' and 'Bloco H'

Business Requirements

1. The material is provided by OUR CUSTOMER/CLIENT, as SUBCONTRACTED goods;
2. At our side, as VENDOR, a Purchase Order must be issued to support this subcontracted material entrance, even though, this is my client/customer material;
3. We need to post goods receipt in special stock type B;
4. Even in special stock B, the material must be available for being used in production orders;
5. Even in special stock B, the material must be accountable;
6. No accounts payable posting expected;
7. Full tracking of the consigned material, from the entrance in our plant untill we sent it back to our customer desired.

Does SAP have a standard solution for this situation?

Thank you very much in advance for sharing your experiences on this subject.
