There are three ways to change the quantity of an item in the Item Listing.
1. Re-enter Item
Scan the item's barcode, click the item on the grid, or enter the item ID for each item.
Each time the item is re-entered, it is added to the existing item line, and the quantity and extended price in the Item Listing are updated. If you want a separate item line to be created each time the item is re-entered, uncheck the Summarize Duplicate Items box in System | Company Setup | POS Information 1.
2. Click Change Qty
Clicking Change Qty opens a window with the item ID and description. Enter the desired quantity, and click OK.
The item quantity and extended price are updated in the Item Listing.
