You do not normally specify currency for a call until you initiate service activity in Call Activity Recording, since billing information is created in CAR. In some cases, however, currency is set in Call Maintenance and you cannot change it in CAR.

Only one currency can be associated with a call, which means that all call lines must be in the same currency. This limitation is imposed by sales order processing, which is the basis of call billing.

Each contract line also reference a currency, which defaults from the end user associated with the line. Any coverage limit amounts on the contract line are defined in terms of the contract-line currency. To apply those limits correctly, the call currency and the contract-line currency must be the same.

As soon as you add an item to a call that derives its coverage from a contract, the call’s currency is set in Call Maintenance and cannot be changed. Any other lines added in Call Maintenance or later in CAR that are covered by a contract must use the same currency, or an error is generated.

See Contract Currency for details.
