After you've added receipts to an invoice, you can record their unit costs.
Load the invoice you want into the Invoice InfoViewer.
You can open an invoice in the InfoViewer by clicking the correct
Invoice # link on
any form that shows the link, such as Lookup Invoices.
Select the Part Receipts tab.
Enable editing in the Part Receipts grid and select the receipt for which you're recording costs.
Specify the unit cost for the parts received in the Unit Cost field.
Specify any additional cost in the Additional Cost field.
Any additional cost that you specify here only applies to the selected
part receipt. You can also use the Additional Costs tab to record additional costs for the entire
invoice.
