I have 3 questions on Google Universal analytics variable mapping.
Hello again @ani2012. @cherr_batac pointed me to this post: https://community.tealiumiq.com/t5/User-Documentation/SERIES-Google-Universal-Analytics/ta-p/9494
Hopefully it will answer some of your questions.
The true "scope" of custom dimensions and metrics is defined in the GA interface when you create the dimension (here I'm referring to hit/session scope, that used to be defined client-side in the legacy GA tag by using different cvar numbers e.g. 3.1).
Google also supports sending hit-level custom dimensions specifically for different kinds of events, for example transaction, product view, product click etc. These events are generally defined by setting the "enh_action" mapping in the tag (see here https://community.tealiumiq.com/t5/Tags-and-Client-side/Google-Universal-Analytics-Tag-Enhanced-E-Co...). These events can be selected from the drop-down boxes in the custom dimensions/metrics tab in the mapping toolbox.
Does this answer your questions?
thanks for your reply and answering my question.
Another question is, what is the difference between "All page hits (set)" and "pageview"?
Does "All page hits (set)" mean even in case of asynchronous calls and "pageview" only in case of a page reload?
And what does the "(set)" mean?
