Plan Data and Multiple Currencies
If your firm sets up Deltek to use multiple currencies, the project and billing currencies that are selected for a project are also applied in project plans.
Your system administrator can select the Use Billing Currency not Project Currency option on the Reporting tab of the Accounting System Setting form ( in the desktop application). If that option is selected, amounts display in the billing currency when you view projects and plans at billing, and they display in the project currency when you view projects and plans at cost. If that option is not selected, amounts display in the project currency when you view plans and projects at either cost or billing.
The currency used displays in the upper-right corner of the Projects form, next to the Billing or Cost option.
