Happy to tell you that I completed both (professional and expert) Adobe Analytics in one shot. Special shoutout to @Jennifer_Dungan  for being my teacher and problem-solver in many places.  Never thought I would complete both exams in less than 1 hour. Thank to all who helped me in this.

The total orders says 47,923 but when I add mobile web, mobile app, and desktop visits the total orders come to 47,093. Is it because of segment overlap? I guess a few orders fall in both mobile app and web devices. How to prevent this and whats the best way to break down device wise?  

Distinct count calculated metric doesn't add up when broken down by device type segments. Total revenue adds up but not the distinct count 

What does " reset" option does in this case?  

This works. Thanks.

I get this when I use    $(this).closest("div.product-name").find("p.limit").text();  

How to get closest value on click using adobe launch? In this case I want to capture product detail in evar when "add to cart" button is clicked. I used the below code. I can see "add  to cart" button value and not the product detail value. Also pls share some content to read on this concept. I gues...

Due to some implementation glitch we didn't track around 1000s of Orders in adobe analytics. Is there a way to import it something like classification? I know we can do classification but the issue is we have lots of variables tracked on product purchase. 

I forgot to mention one thing. We migrated our site to new platform and the page load time improved from 8 sec to 3 sec. Since then we started seeing the gap in orders. Do we need to make some changes in adobe launch to load quickly and capture values?

Both the numbers are off and differ by 7- 8%.
