Does the filter Data Value Changed work on all fields
Hi,
referring to this previous post ( https://nation.marketo.com/t5/Product-Discussions/Best-way-to-count-cookied-contacts/m-p/305041#M171973 ) , it is of big importance for the company the measure the cookied leads over time, month by month.
So I had the idea to create a Smart List , based on a 'Data Value Changed' with attribute 'Original Referrer' ( or by Anonymous IP as an alternative ), with an extra 'Date Of Activity' value ( e.g. in past 30 days ).
The problem is that I do not get any results in my Smart List, although I am quite sure we had some value changes.
Therefore my question : Does The Filter Data Value Changed works on all fields? And If not, how should I solve the issue in counting leads on a monthly base, for which original referrer has been changed ( has a value instead of being empty )
