Where does the transaction currency for nonlabor expenditures come from?

The transaction currency of a nonlabor transaction comes from one of two possible sources.

If the nonlabor expenditure type uses a rate and quantity, then the transaction currency of the expenditure is the same as the transaction currency in the nonlabor rate schedule.

If the unit of measure of the nonlabor expenditure type is currency, then the transaction currency equals the ledger currency.
