Adding a Decision Activity

When you add a Decision activity, you should take into account the following considerations.

Roles

You must add Decision activities within a role lane in the process. When you try to add a Decision activity outside a role lane, Studio prompts you for an already existing role or allows you to create a new one.

The role lane where you add the Decision activity determines which users can access it. Only the users assigned to that role can run the interactive activity.

Transitions

You must connect a Decision activity to the process flow using an inbound and an outbound transition. An error appears in the Problems View if the inbound or outbound transitions are missing.

Variables

Decision activities can access to the following variables:

predefined variables
instance variables

Using Decision Activities as Exception Handlers

You can use a Decision activity to handle a business exception. The activity that throws a user-defined exception is connected to the Decision activity through an exception transition. For more details about exception handling, see Exception Handling in Oracle BPM.
