About Posting - Summary

Posting Costs at Receipt

If the receipt is from Purchasing, the cost used for these postings is the purchase order unit cost. If the receipt is from Production, the cost used depends on whether the job was automatically closed when posting the transaction. If it was automatically closed, the cost used is the actual unit cost from the job. If the job is left open, the system uses the planned cost of the job and makes an inventory adjustment when the job is closed.

Cost Method	Receipt Cost Posted
Average	Weighted average calculation with the result posted back to the Unit Cost field.
LIFO or FIFO	The record is created in the Item LIFO file, recording the date, time, quantity, and cost of the receipt.
Specific	Cost tied directly to the location/lot to which the item was posted. If it was posted to a location/lot that already had a quantity and cost, the new cost is tied to the location and an Adjustment transaction is posted to the Inventory Ledger Distribution Journal. The cost is also posted to the Unit Cost field.
Standard	Standard unit cost is not changed.
