Key Value
The Key Value 1 and Key Value 2 fields are used, by some publications, to limit the volume of alert messages users receive, either by establishing conditions that the publication must satisfy, or by filtering the data to alert you only when the key value is affected. If you leave this field blank, you will receive a message for every transaction.
Specify a Zero (0) in Key Value 1 to suspend alerts. This allows you to temporarily stop receiving alerts without having to unsubscribe from the publication.
Note: These fields are used only
with certain publications. If you populate these fields for other
publications, you will not receive alert messages.
