What is a manufacturer's part number?
A manufacturer's part number (MPN) is a unique number or code assigned by manufacturers to each of their items. Because purchase orders are usually sent to the manufacturer, using the MPN ensures that your vendor knows exactly what is being ordered.
The MPN field is a text field that accepts up to 31 characters and is available for the following item types: inventory part, inventory assembly (purchased from a vendor), non-inventory part.
You can add the MPN to an item using the Manufacturer's Part Number field in the New Item or Edit Item window. You can also change an existing MPN directly on a purchase order after adding the MPN column to the purchase order form.
To add the MPN column to a purchase order
Open the Additional Customization window.
Click the Columns tab.
In the Man. Part Num row, select the checkboxes for either or both Screen and Print, and change the name in the Title field if you want it to show on the form as something other than MPN.
Note: If you change a manufacturer's part number on a purchase order, you're asked if you want to update the manufacturer's part number for that item.
To add the MPN column to the Item List
In the Company section, click Items & Services.
Click Item at the bottom of the list and click Customize Columns.
In the Available Columns list, click MPN and then click Add.
(Optional) In the Chosen Columns list, click MPN and then click Move Up until the MPN column is where you want it to appear in the Item List.
