STO with customer consignment

Hi gurus,

Do you any idea how I can I set up following stock transfer process?

Plant A of company code X delivers the goods directly into the consignment stock of end customer abroad.

This consignment stock belongs to the plant B of company code Y. We need an IC-invoice between X and Y and a delivery document (fill-up) for plant A to end customer delivery.

My first plan was a stock transfer via 643, but the problem is it is not possible to post 101 with customer consignment.

I am trying to set up one central document and all process is covered by this one.

Do you have any idea how this can be solved? Perhaps workflow? Or a new movement type?

Thanks in advance
