Payment Terms Setup Help

I am new to SAP B1 2007A and have to setup payment terms for my company. (Yes, I know we should actually hire a consultant but the Owner thinks that since I am a support / helpdesk guy I must automatically know EVERYTHING about every piece of software ever written)

Any chance someone could help me with the proper settings to get 2% 10th NET 30th terms? (If a BP pays us by the 10th of the following month, they receive 2% off of their invoice. Otherwise the full amount is due on the 30th of that following month)
