Forms: External Task

If triggered, an External Transition creates an External Task. For each External Task, information is shown across a main Details tab, a Data tab and, optionally, across tabs with an Error Message and the Error Message Details - these appear if an error has occurred when raising the task.

Form: External Task Details

The following fields are configured on the main form:

Field	Description
Task Id	Read only: the Id assigned to the workflow task.
Alarm Id	Read only: the Alarm Id that generated the workflow task.
Queue Code	The process queue the workflow task is placed on.
Returned Status Code	The current returned status code.
Created Date	Read only: the date the workflow task was created.
Last Updated	Read only: the date on which any of the workflow task details were last updated.
Completed	Read only: the date on which the workflow task was completed (null if not completed).
Workflow	Read only: The Workflow model this task belongs to.
Transition	Read only: the transition that generated the workflow task.
Alarm Generator	Read only: the Alarm Generator that generated the Alarm that generated the workflow task.

The following fields are displayed through a separate tab on the main Details form:

Field	Description
Description	Description of the workflow task.

Form Icons

The form provides the standard form icons as well as the following:

	Resume workflow. This can be used if an error has occurred when raising this task, the underlying cause of the error has been resolved - and processing the workflow can be re-started.
	Shows the Alarm Generator details that generated the workflow task alarm.
	Shows the details of the alarm that generated the workflow task.
	Shows the user Transition that generated the workflow task.
	Shows the workflow model that generated the workflow task.

Form: Data

The output from the Data Expression in the External Transition that generated this task.

Form: User Task Error Message

This tab will only appear if there has been an error when raising the task. This can happen if, for example, there is a problem when evaluating the expression on a Workflow Transition or an Arc Guard. The tab will, in this case, contain the error message.

Form: User Task Error Message Details

This tab will only appear if there has been an error when raising the task. The tab will, in this case, contain the data being processed when the task was raised.

List: External Task List

The External Task list shows all external tasks that have been generated in CenterView.

The External Task list can be ordered by pressing on the header bar of the column that you wish to sort by. To reverse the sort order, press the header bar again.

The External Task list can be filtered using the icon. Select an existing filter from the drop down list or create a new one to filter the list.

You can open the details of an individual external task by double clicking on a row.

Columns

The External Task List shows a subset of the fields defined on the External Task form above.

Context Menu

By right-clicking on an task in the task list, you will bring up the context menu. In addition to standard items in this menu, from a task list you can select the option to Resume Workflow. This can be used if there has been an error when raising the task, the underlying problem has been resolved - and you want to re-start the workflow.
