I am into a requirement like below.
I would like to get the ticket number as soon as I press the "Create Ticket"
button rather then waiting till actual ticket creation. This is important in
context like following. Say you get a call from one of your customers and he
complains about a issue in your system and you want to create a ticket for
that issue in your RT and give the reference no of the ticket to the
customer on the fly. Since it can take some time to fill all the fields and
create a ticket it is important if you can get the ticket no as soon as you
click “create ticket” button, then you can say bye to the customer quickly,
rather then keeping him unnecessarily till the ticket is actually created.
If some one have done this kind of a change to RT please let me know.
