You can post one purchase invoice for more than one purchase receipt. For example, you have partial receipts from vendor but vendor only issues one invoice per month, and you also need to create only one purchase invoice. You can cover all those receipts with only one invoice. Let’s say, you already have few purchase receipts posted and you need to create a purchase invoice. After the purchase invoice is created (you only need to fill in the information on the header), go to lines and select Lines → Functions → Get receipts lines:
Business Central will display all posted purchase receipts without posted purchase invoice:
Select all lines you want transferred to Purchase Invoice and click OK. Lines will be transferred, and you can continue with invoicing process.
