We have a scenario where we want to pass A4T activities to Data Workbench. For this we need to map A4T activity data to eVars (as its not happening OOTB). But we couldn't find any way to map this yet.
Does anyone have an idea how to achieve this?
I am not a Target expert, so not sure if the answer below can help.
But have you tried using Processing Rules to pass the Activity ID from Target to an eVar? I just did a quick spin off on Target in my sandbox, and I can see that the Target Session ID is enabled. I am sure there will be a Context Data available for Target Activity ID which you can copy to an eVar.
