Custom links populating evars defined for any rule with 'Unspecified'
Hi all
This is slightly difficult to explain but I will try my best.
I noticed in the current implementation I am working on that for events that are tracked as custom links, that whenever an evar has been defined for any of these rules, this populates for all custom links with Unspecified if not explicitly defined for that event/rule. Just wanting to know if this behaviour is expected or if there is a change I could make to avoid this happening? I don't need suggestions of other ways to capture at this point, just if other users see this. Using a very simple example:
I have 2 rule based events that are captured as a custom link, named time and day
During a journey:
the time rule populates evar1 with '11am'
the day rule populates evar 2 with 'Wednesday'
In AA, the data we get appears like the following is happening:
When the time rule fires, evar1 = 11am and evar2=Unspecified
When the day rule fires, evar1 = Unspecified and evar2=Wednesday
So it looks like both custom links are populating all variables, whether a value has been defined for the rule or not. Does that make sense and is this something that is expected?
Thanks in advance for any help
