Awesome, thanks for the info - I am going to write a tickethook to take care of this! Hopefully that does the trick :) Best Regards, Mike McMahon From: dev-bounces@otrs.org [mailto:dev-bounces@otrs.org] On Behalf Of Martin Gruner Sent: Tuesday, June 25, 2013 12:13 AM To: Development community of OTRS Subject: Re: [dev] alter database SOPM Hi Mike, Am 25.06.13 03:37, schrieb McMahon, Mike (HQP): All, Is there a way to alter a database via the SOPM to change a FK relationship? In general, yes. You can use ForeignKeyCreate and -Drop tags for that. I found that I was unable to delete tickets in the system (we have a queue for deleting junky/spam tickets) when one of our custom integrations already had a db entry for it. Here is the setup Cost_estimate => FK relationship on ticket_id So when I try to delete a ticket in the system, the system complains that it's violating the FK relationship on cost_estimate. I need to update the SOPM to alter the key relationship so that deletes are okay (and will cascade/delete entries from the cost_estimates database). I don't think this will be possible. OTRS does not support specification of CASCADE at this point. Additionally I need to update the TableCreate statement to include a proper FK relationship. How do I do this?? Just in the same way as the tables are created in OTRS itself. See otrs-schema.xml. To achieve what you need you probably have to patch Ticket::TicketDelete() to delete all referencing entities.
