Issue

Standard Flats not receiving Automation on 3602-R

Cause

The MailStream Plus™ parameter P ATTR position 66 is where you tell MSP if the piece is automation or not (and other related things).  It contained an [X], meaning "Non-automation compatible piece.  No, do not assign the non machinable surcharge." 
This information is from MailStream Plus™ Guide .
 

Resolution

UPDATED: May 23, 2019
The solution is to change the P ATTR position 66 to [Y] Mail pieces with this attribute are automation compatible.
Then re-run the MailStream Plus process to review the results in the USPS Statement [3602-R].
