Unable to set fields with E-Mail Command option

Unable to set fields with E-Mail Command option

I am sending plain text emails to ServiceDesk Plus (Ver 9.1)  from my monitoring system and need to populated some of the fields in the ticket.  I am not having any success.

The monitoring system places @@@ in the email subject line
The body of the email contains the 2 fields I want to set and the values formatted as shown in the examples @@field=value@@

When I recieve the assignment notification from ServiceDesk, I can see the delimited fields/values in the body of the email (see email below).

The requester account being used is a valid requester, no assets assigned to it.
The incident ticket is created and the log shows it recognizes that the subject has the "@@@", however neither the Asset or Category fields are filled in.
I have tested using my credentials and the resulting ticket has the Category field set, but the Asset field does not change.

Are there any restrictions on using the E-Mail Command ?


Thanks
Sal
