Order source
An order source lets you track how you receive orders from customers. For example, you can set up an e-mail, fax, phone, or walk-in order source. Order sources are for your reference and you can define your own reports in the Sales Analysis application to track these sources. See Inquiring on and printing sales data.
You can assign a default order source to a user ID, assign an order source to an order during entry, or leave the order source blank. Whenever you specify an order, the order source assigned to the user ID will default, but you can override it at order entry.
