How can I configure expense report number prefixes for different business units?

If you select alphanumeric prefixes for expense report numbers, then you must enter the Expense Report Number Prefix as a setup option. You can define prefixes at the implementation level on the Manage Expenses System Options page, which applies to all business units.

You can also specify exceptions for specific business units or define the prefix for each business unit on the Create System Options: Specific Business Unit dialog box.
