Sales Cost Update at Compartments Load Confirm with In-Transit Inventory

Hello,

Is there a way to trigger Sales Order Detail Line cost update when confirming a compartmentalized load with in-transit inventory tracking and using weighted average costing? I encounter the following issue:

1) Inventory/Sales Cost Method is 02-Weighted Average for finished goods which are sold to customers, using Sales Order Management & Transportation Management.

2) Load type is CI - compartments in transit.

3) I create a Sales Order on Day 1 for product A with a quantity of 1000, having a weighted average cost of 1 at that time, so the value is 1000 x 1=1000$. The shipment is put on a load and the load is approved.
