GR Based IV
What is the Purpose of using GR based IV in Purchase order ?
Explain in detail
GR Based IV is a procedure in Invoice Verification allowing assignment of incoming deliveries and invoices to an item of a purchase order.
If goods-receipt-based Invoice Verification has been defined for an order item, an invoice for the order item can be entered with reference to a goods receipt document or a delivery note number entered at the time of goods receipt. In the process, a separate invoice item is created for each goods receipt. Checking of price and formal accuracy of the invoice is performed at this item level.
In Other words, If you Set GR Based IV then system wont allow you to Enter Invoices Without GR.
That means If you want to Perform Invoice Verification with out Gr you Should not Tick the Option.
