# Invoice purchases for commodity items

Once you have entered commodity class cost component factors for a new cost period, you can recalculate the lines on purchase documents that fall within the period based on these cost factors. After updating the costs on a commodity purchase order, it is ready to be invoiced.

## Steps

1. In the search box, enter **Commodity Purchase Orders**, and then choose the related link.
2. Open the commodity purchase order you want to invoice.
3. Update the costs on the purchase lines:
  - If you are calculating commodity costs from cost factors, review and if necessary adjust the values in the **Commodity Payment Class Code** field, then click **Actions**, point to **Functions**, and click **Calculate**.
  - If you are applying a fixed cost to all purchase lines, fill in the **Blended Commodity Unit Cost** field on the **General** FastTab.
4. Post the commodity purchase order.
