   • Description: Enter the function description.

4. Click Save And Continue. The function editor opens.
5. Enter the JavaScript code of the function body. Note that Zuora provides the other parts of the function except the function body by default. See the following snippet as an example. It can be a validation or formula function. For more information, see Function types, Function format, and Use cases and code samples.

   ((account) => { //Available by default
    … //Function body. Enter this part in the field 
   })(account) //Available by default
