Hi, I just tried to hack Date.pm to a new DateChecksum.pm (for an additional checksum appended to the regular TTN, like in STTS2). I did this, but in $HOME/var/log/procmail-2002-06.log there is a line like this: Undefined subroutine &Kernel::System::Ticket::Number::DateChecksum::GetTNByString called at /opt/OpenTRS/bin/..//Kernel/System/PostMaster.pm line 235, <STDIN> line 39. procmail: Non-zero exitcode (255) from "/opt/OpenTRS//bin/PostMaster.pl" Do I have to register the new Ticket hook anywhere or did I just a stupid mistake during coding? BTW: I attached the new module. BTW2: Is there a specific reason, why the default TTN is smthn. like that: 10001? Why the leading '1'? I want to create TTN's like in STTS, rotating the TTN's on a daily basis via cron. Stefan -- Stefan Schmidt Email: jsj@jsj.dyndns.org jsj@exsuse.de Bremen jsj-hb@t-online.de s.schmidt@iu-bremen.de
