A Notification Phrase specified in "Reply Success" email does not work. The syntax of the specified Notification Phrase is not converted to an actual Incident number in the Reply Success email. Also the syntax of the Reply Subject is not converted as per the following screenshot.
STEPS TO REPRODUCE:
Release : 17.3
Reply Subject only supports plain text and ticket reference fields. (@{call_req_id.ref_num}) cannot be used as it cannot be resolved by SDM Maileater with the existing design.
The Reply Success Text does support the notification phrase. Usually the notifications are part of the activity log, so the notification phrase which contains call_req_id.ref_num will get resolved in case of a manual notification as it is in the context of activity log.
For the SDM Maileater case, the mail is being sent in the context of ticket creation and not the activity log, so the notification phrase should contain only ref_num and not call_req_id (which is an act_log attribute)
Please try creating a copy of the Reply_Incident notification phrase and change the content from
