Cathy,
Like the links system, the Evo Notes are only accessible in the Grids, So the current T6SOA does not use Evo notes, I am working on a T7SOA right now, and that uses the Evo Notes. So for the short time, if you want to use Evo notes on SO's you must do some type of lookup to the SO and enter the notes there. I know not a great solution..
I just got off the phone with Lynn and I was explaining this issue to her, and we came up with a possible solution. I will try to have T6SOA also save its notes to the CSN & CSH Evo notes. Currently only T7ARA,T7APA, T7POA, T7SOA, T7WOA do this and T7POA & SOA have not been released yet.
