When creating a loan category that will be using a new suffix range, you will need to first create the account suffixes using Tool #105 "Account Suffix Configuration."  Choose the option "Type" from the drop-down and hit enter. Fill in the Account type range and enter - this must be done before filling the 3 following fields. Then fill out the Application type, Description, and Receipt description fields and enter. Once the account type range has been established, you can use the suffixes in your loan category.
