A wired activity runs or is skipped depending on the process flow. You can choose to make
the activity conditional so that a user can decide at run time whether to run the activity, or you
can use a script to make the decision.
Procedure
Complete the following steps to implement a conditional activity.
- Open a process.
- Select the activity that you want to make conditional.
- Under Conditions in the properties section, select the
Conditional option.
Restriction: The conditions tab is disabled for ad hoc activities (unwired
activities). If a wired conditional activity is turned into an ad hoc activity by deleting wires to
and from the activity, the
Conditional option becomes disabled. To set
conditions for an ad hoc activity, use preconditions. See
Creating an unstructured (ad hoc) activity
The activity in the process diagram includes a diamond-shaped icon to indicate that it is
conditional. The diamond-shaped icon on an ad hoc activity indicates that the activity has a
precondition.
- Select the conditional activity for execution by using one of the following
options:
Option |
Description |
JavaScript |
Enter JavaScript in the available box. It returns a valid Boolean
(true or false ) value. If the runtime return value of the supplied
script is true , the activity is carried out. Note: If a script is present in the
box, it overrides any human decision at run time to carry out or skip the activity.
|
Set selected conditional activities |
If the Conditional option is enabled and no JavaScript is entered in
the box, the activity is carried out only if previously selected. Use the
tw.system.process.selectedConditionalActivities property to set selected
conditional activities. |
