How can I invoice multiple PO receipts on one invoice?
Go to Purchase Orders / PO Transactions / Invoice Entry and enter the invoice number and the vendor number. To the right of the Receipt Number and Receipt Date fields, there is a checkbox field 'From Multiple Receipts'. Select that option and then click on the Zoom button to the right of that field to get your detail grid for selecting which receipts to invoice.
When you have finished selecting the receipts, click on Invoice then Close.
All the detail lines from the receipts selected will be populated in the detail grid on the invoice. Edit the invoice details as necessary and post.
