WORKING WITH EVENT TASKS

We can define events in the workflow to specify the sequence of task execution.

Types of Events:

• Pre-defined event: A pre-defined event is a file-watch event. This event Waits for a specified file to arrive at a given location.
• User-defined event: A user-defined event is a sequence of tasks in the Workflow. We create events and then raise them as per need.

Steps for creating User Defined Event:

1. Open any workflow where we want to create an event.
2. Click Workflow-> Edit -> Events tab.
3. Click to Add button to add events and give the names as per need.
4. Click Apply -> Ok. Validate the workflow and Save it.

Types of Events Tasks:

• EVENT RAISE: Event-Raise task represents a user-defined event. We use this task to raise a user defined event.
• EVENT WAIT: Event-Wait task waits for a file watcher event or user defined event to occur before executing the next session in the workflow.

Example1: Use an event wait task and make sure that session s_filter_example runs when abc.txt file is present in D:\FILES folder.

Steps for creating workflow:

1. Workflow -> Create -> Give name wf_event_wait_file_watch -> Click ok.
2. Task -> Create -> Select Event Wait. Give name. Click create and done.
3. Link Start to Event Wait task.
4. Drag s_filter_example to workspace and link it to event wait task.
5. Right click on event wait task and click EDIT -> EVENTS tab.
6. Select Pre Defined option there. In the blank space, give directory and filename to watch. Example: D:\FILES\abc.tct
7. Workflow validate and Repository Save.

Example 2: Raise a user defined event when session s_m_filter_example succeeds. Capture this event in event wait task and run session S_M_TOTAL_SAL_EXAMPLE

Steps for creating workflow:

1. Workflow -> Create -> Give name wf_event_wait_event_raise -> Click ok.
2. Workflow -> Edit -> Events Tab and add events EVENT1 there.
3. Drag s_m_filter_example and link it to START task.
4. Click Tasks -> Create -> Select EVENT RAISE from list. Give name
5. ER_Example. Click Create and then done.Link ER_Example to s_m_filter_example.
6. Right click ER_Example -> EDIT -> Properties Tab -> Open Value for User Defined Event and Select EVENT1 from the list displayed. Apply -> OK.
7. Click link between ER_Example and s_m_filter_example and give the condition $S_M_FILTER_EXAMPLE.Status=SUCCEEDED
8. Click Tasks -> Create -> Select EVENT WAIT from list. Give name EW_WAIT. Click Create and then done.
9. Link EW_WAIT to START task.
10. Right click EW_WAIT -> EDIT-> EVENTS tab.
11. Select User Defined there. Select the Event1 by clicking Browse Events button.
12. Apply -> OK.
13. Drag S_M_TOTAL_SAL_EXAMPLE and link it to EW_WAIT.
14. Mapping -> Validate
15. Repository -> Save.
16. Run workflow and see.
