#Allow Over Delivery/Billing

While creating Delivery Note, system validates if item's Qty mentined is same as in the Sales Order. If Item Qty has been increased, you will get over-delivery validation. If you want to be able to deliver more items than mentioned in the Sales Order, you should update "Allow over delivery or receipt upto this percent" in the Item master.

Item's and Rate is also validated when creating Sales Invoice from Sales Order. Also when creating Purchase Receipt and Purchaes Invoice from Purchase Order. Updating "Allow over delivery or receipt upto this percent" will be affective in all sales and purchase transactions.
