[OPEN-ILS-GENERAL] Evergreen Title Control Number (TCN)

[Harbottle, Joel R]

Hi Jason,

Thank you for your reply to my question and your help.

In regards, to the TCN when you say Evergreen will export it to tag 901 or
903, if I were to insert my own custom TCN into one of these fields when
cataloguing will Evergreen naturally use this as the TCN or will it still
assign a system generated number?



In regards, to field 001 how would I go about setting up a database trigger,
as this is something I’m not completely familiar with yet.



Kindest Regards,

Joel
