Trigger Task Action



See Also

Trigger Task Action-Setting Properties, Start Another Task Action,  Stop Task Action, Create Variable


Starts a managed task as if it were triggered. All managed task properties will be utilized including Logon, Priority and Security settings.

Practical Usage

Used to cause another task to trigger. When a task is triggered, all of the parameters in the Managed Task Properties (i.e. Security, Priority Logon properties, etc.) are applied.  

IMPORTANT NOTE: This is not the primary means for starting a synchronous sub-task (a much more common scenario), to simply start a sub-task use the Start Task Action instead. The Start Task action contains much greater capability in terms of error handling and passing variables to the sub-tasks.

This action should only be used when the started task should run asynchronously (execution of the parent will not wait for the sub task to complete) and the other managed task properties such as Priority should be applied.


General Tab

Managed Task to Trigger

Text, Required
a) MANAGEDTASK="Talking Clock"
b) MANAGEDTASK="Foldername\Talking Clock" 

Specifies the name of the managed task to trigger. The task must exist in the current machine task list at runtime or the step will fail.  
NOTE: Changing the task name or parent folder name later can break this linkage once created.

Run Password

Text, Optional
MARKUP: PASSWORD="mypassword" 

If the task has been encrypted, specifies the password that should be used to decrypt it so that it can start.
