Split sales/distribution process based on Country of Origin

Hi

Background :

We have some products we would like to produce in two different countries.

Goods are produced and shipped to a Central distribution warehouse and distributed from this warehouse to different countries.

Pick and pack is done in e1 Advanced Warehouse.

Planning is done using MRP

Problem

Our licence to sell in a country is tied against the country (of Origin) where goods are produced. And approval of distributing from another Country can take a long time.

So we need to be able to control witch "Country of Origin" to sell to a specific customer, until approval has been done.
