This means the Tracker Entry was generated by the online banking A2A transfer program to record changes made by the member to a recurring A2A (A2AFT) record via online/mobile banking. These Audit Trackers are attached to the account suffix where the funds are being withdrawn (for an outgoing A2A) or deposited (for an incoming A2A).  The memo type used on these conversation notes is specified as part of your credit union's A2A Transfers configuration settings via Tool #569: Online/Mobile/Text Banking VMS Config.
