Intercompany - subcontractor (manage customer SC-components) S/4Hana 1809

[former_member453859]

Hi SCE Experts

Scenario/Business case.

1. Plant a) STO with subcontracting (provide some components without selling)
2. Plant a) provide components by SC-delivery to plant b) in different company (with proforma invoice for customs clearance).
3. Plant b) receive customer SC-components --> into unvaluated stock belonging to the "customer"
4. Plant b) BOM/Receipt (contain customer SC-components & other components)
5. Plant b) production --> consume SC-components from stock belonging to "customer"
6. Plant b) create STO-delivery for finished good and ship to plant a)
7. Plant a) create inbound and stock placement

I am struggling to propose a proper solution for 1809 for step 3 which gives a proper document flow (receive versus PO or inbound delivery. We would like to use SPED in step 2. to create an inbound delivery in plant b) to receive the customer SC components.

Its not a MTO scenario. It should be a MTS scenario, as the provisioning should be based on MRP (minimum stock, re-order point MRP area for SC-vendor in plant a)

Any ideas/solutions?

Thanks alot Wernher
