Stock Transport Orders

Hi

The scenario is like this

Suppose we take HUL(Hindustan Unilever) as one client. He want to have a Inter company Stock transfer between two plants in different company codes, but he dont want billing for this. My question is what are the accounting documents that are generated in this scenario and how accounts will be settled. Suppose stock transfer happens between plants that are in two different countries, some taxes will be levied on this goods, then how accounts will be settled without billing documents.

Here my requirement is Inter company STO without billing document

Can anybody pls throw some insight on this

Thanks
