Prism Users Guide - Chapter 3. Transactions
3.6 List Items on Transaction

You can use the following methods to list items on Prism transactions:

• Scan the item's barcode to list the item immediately on the transaction.
• Use Advanced Item Lookup to search inventory for the item.
• Type the item's full UPC or ALU into the Item Lookup field and press the key.
• Import a list of items from a file.

Items are listed with a default quantity of one. Use the Quantity button to adjust the quantity as needed. Make sure each scanned item has been entered on the transaction before scanning the next item. Global UPCs cannot be used to lookup items on transactions. To lookup items by UPC in RP Prism, you must use Local UPCs and have a Local UPC entered for each item in RIL.
The maximum number of items on a single document is 5000.

3.6.1 List Items by Scanning

1.    With the cursor in the Lookup field in the item grid, scan the item's UPC bar code. The item is listed on the receipt with the default quantity of one (1). Repeat for each item being purchased.  (Alternatively, you can type all or part of the UPC in the Item Lookup field and press .)

3.6.2 List Items by Searching Inventory (Advanced Item Lookup)
You can use the Advanced Item Lookup feature to search inventory. Click the magnifying glass icon to open the Advanced Item Lookup search screen.

Select search elements and enter search criteria. Click the Search button.

When you find the item(s) you want to list on the transaction, enter a Doc Qty for each.  Click Close. The items and quantities are brought to the transaction.

See the Item Lookup topic for more information.

364.3 List Items by Import
You can import a list of UPCs, ALUs, or Item Numbers to populate the item list on a document. Importing a list of items is especially useful when a local store has only a single or limited number of POS systems. 
See the Import Items topic for details.

3.6.4 Remove an Item
1.    On a transaction in progress, select the item to be removed and then click or press the Remove Item button.    

Void Tenders before Removing Item
If you have taken tenders, you must first void the tenders before removing an item.

3.6.5 Change Item Quantity
1.    Select the item in the item list, it is not selected already and then click the Quantity button.    
2.    Enter the desired quantity in the text box.    
3.    Click the check mark icon (or press Enter).     

Decimal Quantity Items
When a user lists a decimal-quantity item on a document, a prompt will be displayed so the user can enter the desired decimal quantity for the document.  The number of decimals available is based on the value of the Qty Decimals field in the item record in Prism Inventory. The default quantity is 1. The prompt will display the number of decimal places configured in preferences (Admin Console > Node Preferences > Language & Locale). Enter the desired quantity in the dialog. Note: The Enter Quantity dialog is only displayed for decimal quantity items.

The "Prompt for decimal qty items" preference enables retailers to control whether or not a prompt is displayed when a user lists a decimal quantity item on a transaction. The preference is located in Admin Console > Node Preferences > Transactions > General and is enabled by default

• When enabled, when a user lists a decimal quantity item on a transaction, a prompt will be displayed to enter a decimal quantity. The user must enter the desired quantity.
• When disabled, no prompt is displayed when a user lists a decimal quantity item on a transaction. The quantity defaults to "1".
