Intercompany drop order receiving Organization

Summary:

Step 1: Product is transfer from US to Singapore using a TO. With Inter company accounting settlement is completed.

Step 2: Singapore raise a sales order to customer and ship from Singapore by using a entity as US to Korea customer (Intercompany drop ship). Where as Inter company will clear the settlement for both SG & US. However, when customer return the product we want the product to be shipped directly to US not in Singapore (Organization is not same as source order). Which is balancing the additional Inventory value in US books. Howe can handle this configuration to show Singapore received and sent to US virtually.
