About Output Parameters

When creating your Web Service methods, user-defined actions, processes and process flows you might need to define output parameters in order to return values computed by that action, process or process flow element. Output parameters are necessary when some data needs to be returned. User-defined actions defined as functions must have one and only one output parameter.

Examples

Mortgage_monthly_value, Employee_age
