**Example**
We have an *Orders* dataset with a *Freight* field.
In this example we will attempt to convert the real values in this field to string values representing currency. We will map the *Freight* field to the *data* field of the function transformation object.
We will also use a *Variables* object to specify an acceptable Microsoft.Net format for currency.
Where,
*Format* = C
In the output window, you can see that the provided data from the *Freight* field has been converted to a string representing currency.
