I did and it did show up. But the problem is that field only appear when ticket already repeat at least one time, am I correct? For example, now I create a recurrent ticket same month and day in next year, after 3 months and I did a search, OriginalTicket should not create as it haven't been repeat, please clarify if something wrong in my concept. Thanks.
You're correct, the initial ticket doesn't record a link to itself which would allow you to search on it. To track down the repeating tickets that haven't repeated yet, look at the code in the rt-repeat-ticket script you schedule in cron. It looks for all tickets with attribute 'RepeatTicketSettings'. You could just put a debug statement in that script to print the ticket id of each ticket, then run the script.
