Warning: Make a backup of your data before proceeding with these remaining steps as you will be prompted to upgrade the AP Master file. Refer to article 17256 "How do I use File Tools to back up data files?"

1. In Accounts Payable select File, Company Settings, AP Settings, Orders.
2. In the Payments, select Vendor if you want to have multiple jobs or prefixes on one check. The other selections could print multiple checks for a vendor if the invoices selected for payment for the vendor are for multiple jobs or GL prefixes.
