The Expense Level setting limits the levels of the accounts that are displayed when accessing the Account field look-up on an expense line.
In Costpoint, each account number may have multiple segments/levels as part of the overall account number structure. For example, 588-30 represents two levels, while 588-30-03 represents three levels. Depending on the circumstances, both levels may allow charging, but the end user may be limited to choosing only the level 3 account. By using the Expense Level setting, an administrator can limit which levels any user is allowed to access.
