Computing values in processes

To evaluate expressions in processes

1. Log in to BMC Helix Innovation Studio and navigate to the Workspace tab.
2. Select the application in which your process exists.
3. In the application, click the Processes tab.
4. Click the process name that you want to modify to obtain expression values.
   The system opens the Process designer and displays the process diagram on the canvas. 
5. Drag and drop the Compute Value Service Task to the canvas and place it at that point where you want the system to evaluate an expression.
6. In the Properties pane, enter the values for the properties.
   The following table provides more information about the Compute Value properties:

   Property	Description
   INPUT MAP	Custom expression that represents an arithmetic or a function expression. You can build a custom expression and use the output of the expression in your process. For example, build an expression to concatenate input parameters with static values and use the expression output in different actions.
   OUTPUT MAP	Process parameters that you want to obtain as output values from this Compute Value Service Task. You can build an expression for assigning an output value to a process parameter.

   For more information about the common Service Task properties like Run as, Multi instance loop, see Service Task properties.

7. Click Save.
