Error Intermediate Event is used to redirect process flow execution to an alternate path in case of failure of any activity during process flow execution. To understand the use of Error Intermediate Event, consider the following process flow:
In this process flow, data from a text file is converted to an excel file using layout and mapping activities. You may want to be notified if the mapping activity fails during process flow execution.
To handle this situation, you can attach Error Intermediate Event with the mapping activity so that in case mapping activity fails, a notification activity is executed and sends an email to the specified email address. Use of Error Intermediate Event is displayed in the following figure.
To use Error Intermediate Event:
In the Process Designer, click the activity in which you want to attach the event and select Options
icon from the Context Pad and then select Add Error Intermediate Event.This attaches the Intermediate Event to the selected activity.
Drag the Mail notification activity to be executed, in case of failure of the mapping activity, to the Canvas area.
Connect the Error Intermediate Event to the notification activity, for example, Mail Notification activity and then Mail Notification activity to the End Event.
While connecting Error Intermediate Event with Mail Notification activity, ensure that you are connecting Error Event with Mail Notification not the Mapping activity with Mail Notification.
