Available Expense Types and ODC Elements

The Available Expense Types field will contain a list of all active Expense Types that are not currently assigned to this Cost Structure.  The ODC Cost Elements select box will contain a listing of all ODC elements defined in your system.  The ODC elements are defined on the Admin >> Setup >> Cost Elements screen.  

Each Expense Type must be paired with an ODC Cost Element when assigning it to a cost structure and can only be associated once, whereas, each ODC Cost Element may be associated with many Expense Types for a given Cost Structure.
