How to acquire parameter values from other process elements
Parameters can take their values from other parameters. The process of linking one parameter to another is called “mapping”. For example, if the process is triggered by an object signal event, you can map other parameters of that process to the parameter of the initial signal that contains the modified record.
To acquire a parameter value from another process element:
1.Double-click the required process element in the working area of the designer, for example, the [Perform task].
2.Click the 
button in the needed field of the properties area to change its value. For example, click this button in the [Account] field of the [Perform task] element setup page to connect a task to an account.
3.In the parameter value menu, select [Process parameter]. In the opened parameter window, select the element that contains the needed parameter.
4.Select the parameter that will be used as the source and double-click it (Fig. 87).

5.Save the changes.
As a result, the parameter value will be passed to the process element.
Note
The parameter page will display only compatible parameters. For example, the source of the [Account] parameter can only be a lookup parameter whose value is an account. Date and time parameters can only be mapped to other date and time parameters, etc.
