### **Example**

In this example, we will be passing the required parameters to the function transformation object using a *Variables* object.

Where,

*rate* = 1.0123

*periods* = 0

*numPeriods* = 1000

*PV* = 20000

Right-click on the function transformation object and select *Preview Output.* You can see that Astera Data Stack has applied the Pmt function, and returned the payment value.
