A trigger action is an operation that occurs when an operator enters a tag value that is outside the limit specified for that tag. You define a trigger action in the Trigger Action window.
Trigger actions are used in both desktop and mobile device applications. You can combine those actions and employ them for any limit specification.
You can review all the trigger actions that you have defined in a tour in the Trigger Actions Overview window. See View all trigger actions in a tour.
General tab
On the General tab, you can specify any combination of the following actions when a limit has been violated:
-

-
Overrides the specified tour level limit action to either accept or reject the value that violates this limit.
-
Require Signature on device
-
Prompts the operator to sign the data before navigating to a different tag on the data entry screen. See Require Signature trigger action.
-

Requires the operator to enter a comment before the value can be accepted.
-
Prompt Message

Work Request tab
On the Work Request tab, you can select Generate Work Request as a trigger action. This defines an automatically generated work request if a value violates the specified limit. If selected, a work request is automatically generated and put into the Work Request queue for later review.
