Occurrences vs Instances

[1982luca]

Hello everyone,

 Basically, I have undefined value with evar company if I use occurrences while I have zero undefined if I use Company Instance. Can you help me to understand this dashboard? When shall I use Occurrences and when shall I used Instances?

Thanks

Occurrences metric will take into account persistence as well. Instances will only take into account those Hits where the value was actually set. So, we can say that Instances + persisted values = Occurrences.

Hi @ishans52004352, why I have unspecified value? For your information, Company evar is set by Adobe Analytics 1.4.

Thanks
