Sometime you want to do an analyse only when one or more conditions are true, if the are not true you want to exit the analyse, so steps below the conditional exit are not evaluated/executed. The conditional in Analytics should look like:
if condition = true then exit analyse
At the moment this is only possible with the function NoOutput(), but then the mapped attribute should be connected to an PIPoint and you have to fill in a else condition. All rows below the conditional exit will not be executed.
