The "Note" field is able to be selected and added to the AR detail report.  This field has to map to somewhere.. It'd be tragic if this incredibly helpful feature didn't work due to a simple programing fix.. e.g. mapping the report field "Notes" for the AR Aging Detail to the "Transaction" Level Notes in the AR area.

I wonder which note field is QB's go to for "Notes" or if they didn't bother to map the incredibly useful field.   

We're talking between 5 minutes of report mapping experts time or up to a couple hours.
