Discount individual charges on a sales transaction form

The Discount percent field on estimates, invoices, sales receipts, refund receipts, and credit memos applies a discount to all activity on the form. How do I use the Discount field?

However, if you want to apply a discount to just one charge, you can use one of these solutions:

• Create an additional charge line with a negative amount. This will account for a discount on a single charge.
• If you need to report the discount against a particular account, create a discount product or service and use it here. How do you set that up?
