K2 Rules and Logic - Exception Rule

The Exception Rule is identified by the icon.

There are three main configuration options available for exceptions:

Insert the required exception code within the process exception class (see below)
Log exception to the server	Enabling this option adds the execution of an exception to the K2 Server log	Click on the Check Box
