The Expense Management system offers a flexible way to define GL Expense Accounts for each expense category and business unit type using the Account Mapping Definition program (P20106).
For example, a company uses account 8740 to record expenses for airfare except when the business unit represents a project. For projects, the company uses account 1362 to track airfare. To achieve this, two records need to be entered in Account Mapping Definition (P20106) for that expense category, one for all Business Unit types, and one where the Business Unit Type for projects is specified.
The system will concatenate the Business Unit (data dictionary item MCU) from each expense to the Object and Subsidiary to establish the expense account to be used for the reimbursement voucher or time card.
