Anthony, I am assuming that the shipment cost is calculated as a "delivery cost" which accrual is carried into the purchase order as planned delivery. What I would look at is introducing a process where:
- Perform a goods receipt of the inbound delivery into valuated goods receipt stock using movement type (107)
- When goods arrive at the distribution center perform the final goods receipt (109)
The movement type (107) will perform the financial posting but not the inventory posting.
This is called Origin at Acceptance. I realize the inbound delivery usually comes configured with the 101 movement type. However this can be updated through enhancements and different category keys.
Regards,
Steve
