17 Alerts
17.1 Creating Alerts
The easiest way to define an alert is by using the Alert Wizard, which can be invoked from the Tools
menu. Alerts may also be created and maintained in the Alerts dialog, which can be opened from the Tools
menu. Alerts are stored as part of the QlikView document. Alerts can only be created and triggered from Windows
versions of QlikView (that is, not from AJAX clients).
17.2 Using Alerts
QlikView alert checks can be triggered in three different ways:
1. Automatically in the QlikView layout when there is a probability that the document’s data has
changed, i.e. when the document is opened, when the script has been executed or when a Reduce
Data operation has been performed.
2. Manually from a macro via special Automation APIs. Refer to the QlikView API guide for details.
3. External programs running QlikView in batch mode have a special Automation API to retrieve a list
of fired alerts from a given context.
The chain of events following the triggering of an alert check can be shown as follows:
Alerts can be suspended after being fired until a change occurs. As an example it may be quite annoying to
be reminded every time you open a document that your budget goal has been fulfilled. In that case you may
set the alert to fire only once and then suspend itself until next month.
As can be seen in the flowchart, each triggering of an alert initiates a chain of logical operations in the Qlik-
View document. Typically QlikView has to perform the following major steps:
