I am trying to export closed dates from the os ticket but it will not export.
I've found and modified the the class.export.php file below, I've tried to change the Keys to close_date, closed, closedate, isclosed etc.
return self:($sql, array( 'ticketID' => 'Ticket Id', 'created' => 'Date Created', 'subject' => 'Subject', 'name' => 'From', 'priority_desc' => 'Priority', 'dept_name' => 'Department', 'helptopic' => 'Help Topic', 'source' => 'Source', 'status' => 'Current Status', 'effective_date' => 'Last Updated', 'closed' => 'Close Date', 'isoverdue' => 'Overdue', 'isanswered' => 'Answered', 'assigned' => 'Assigned To', 'staff' => 'Staff Assigned', 'team' => 'Team Assigned', 'thread_count' => 'Thread Count', 'attachments' => 'Attachment Count', ), $how);
