What is the purpose of the Invoice History button (up in MORE) ?? and why is it .. 

We had Customer A .. and we were trying to find out information as to how some invoices were paid.  

Normally I click on the binoculars, and click the box that states ZERO balance invoice and they show up in the "invoices" tab (6) 

This time NOTHING was transferred over .. the invoices I was questioning, were from 2015 ?? does that make a difference, and if so .. is the only way I can find out payment information through Explore ..??  

I guess I'm not understanding why if you're "calling" for the items .. they will not show up in the invoices screen to reference payment information.  Does closing months/ years have an affect on this availability ?? 

We are upgrading to 2016 tomorrow .. will this be the same on there  as well ?? 

Thank you
