Adding a Due Transition

In this task we add the Send Reminder automatic activity, which will remind the employee that a report he has submitted requires editing. Since we want this activity to execute after a given interval of time has elapsed, we will connect to it with a due transition.

The due transition fires as a function of the activity it is sourced from. You will add a due transition which will be taken when a certain amount of time has passed since an instance has arrived at the Edit Report activity.

To add the Send Reminder activity and Reminder Due transition:

  1. Right-click in the space below the Edit Report activity and click Add Activity > Automatic (Automatic Activity icon 
				). The Activity dialog box appears.
  2. Enter Send Reminder in the Name field, and click OK. The Send Reminder automatic activity is added to the diagram.
  3. Right-click on the Edit Report activity and click Add due transition (Due Transition icon 
				). The mouse pointer will begin dragging a transition line.
  4. Click on the Send Reminder activity. The Transition from Activity dialog box appears.
  5. Enter Reminder in the Name field.
  6. In the Properties page, enter '2m' (complete with the single quotes) in the expression text box, and click OK. The Reminder due transition is added. We set the interval at two minutes so you will not have to wait long when testing this part of the process. A reasonable reminder interval would of course be much longer.
  7. Click and drag on the Reminder due transition to curve it towards the right.
  8. Right-click on the Send Reminder activity and click Add unconditional transition.
  9. Click on the Edit Report activity, and then drag the transition towards the left. See the diagram at the bottom. The unconditional transition is added.

After completing this task, your process design diagram should look like this:
