How to add additional costs to the item in an inter-org transfer across LE.

Hi,

We have a situation wherein the procuring Org or the Shipping Org is different from the Selling Org. So we used the inter-org transfer between the LE/OUs with invoicing enabled. Now for the selling organization, when it receives the items into its inventory, there are additional costs which are incurred during the physical flow of goods, like customs, freight, insurance, handling fees etc, which we want to be added to the items that we have received through the Inter-Org transfer process (Internal Requisition -> Internal Sales Order).

How does the Selling /Receiving Organization add these additional costs to the items. We are using average cost setup for inventory organizations.
