We want ticket numbers to be as short as possible so that they don't swamp mail message Subject lines. As an experiment while testing 1.1.0-RC1 I changed SystemID to 1 and TicketNumberGenerator to AutoIncrement, and promptly started getting ticket numbers of the form 100005, which was fine. This morning, after upgrading to RC2, ticket numbers have suddenly jumped to starting at 110001. Why is that? What will happen when 1.1.0 proper comes out next week? Jim

I agree! But I find that even "100005" is too long. "1005" (two characters shorter) would be better.

I omitted to mention that I've also set TicketHook to a 2-character string, so a Subject line now looks like [SN: 100005] Re: 1.1.0-RC2 Ticket Number Generation for example, which is quite an improvement on [Ticket#: 2003042510000059] Re: 1.1.0-RC2 Ticket Number Generation Jim

That's is fine, but "[SN:" is a problem, because a well known email program is replacing SN: (two characters and :) with RE:! -=> New subject after customer replying will be "[RE: 100005] Re: 1.1.0-R..." and OTRS can't detect a follow up (a new ticket will be created). Use always min. three characters for TicketHook.

Ah, I misunderstood. I was aware of the warning in the documentation Note: Don't use 'TN', because MS Outlook is replacing "TN: 54968797" with "RE: 54968797" and then you will run in trouble. but it gives the impression that the problem is specifically with 'TN', not with any 2-character string.

Is it safe to change SystemID once OTRS is up and running? We plan to go live with OTRS once we have 1.1. bedded down. However, we are still deliberating over the ticket number format to use. One idea that has just cropped up is to use SystemID to represent the year, along with the new MinCounterSize set to 4, so that ticket numbers would start off at 30001, an change to 40001 next January. I would like to check if there might be any hidden drawbacks to changing SystemID (and var/log/TicketCounter.log)? I've just tried it on my test system, and nothing bad appears to have happened so far. Jim

Don't change the SystemID if the system is up and running. Reason: The ticket number has two functions a) CreateTicketNr() - used to create a new ticket number b) GetTNByString() - used the check it a email is a follow up -=> If you change the SystemID then OTRS will not find email follow ups for old ticket numbers. Solution: If you want to change the SystemID, patch the GetTNByString() function or write a own ticket number module (maybe without SystemID). If you can't write a own module we will give you assistance on dev at otrs.org

How does the number correlate to the ticket number? With it set to "3", my ticket number looks like: [Tkt#: 10003] I wouldn't have expected a 5 digit number with the counter size set to 3.

Ticket number format for AutoIncrement module is: <SystemID><Counter> Example SystemID is 10 and MinCounterSize is 3 -=> 10005 or 10006 or 10017 Example SystemID is 2 and MinCounterSize is 2 -=> 205 or 206 or 217 The SystemID is used as prefix (to see if it's your system or not!).

What will happen when 1.1.0 proper comes out next week?
There is nothing changed in the ticket numbers code! If you use the AutoIncrement module check the following: 1 00005 ^ ^^^^^ <-- 5 digits (auto increment) | SystemID The auto increment counter file is "var/log/TicketCounter.log". If your ticket number is now 110001 then it looks like somebody changed the "var/log/TicketCounter.log" manually (maybe if you use the tar)!
