[otrs] OTRS 2.4.7 - Agent Tickets Search Result Close time

Hi, I have this question: I would like to perform a custom research in my otrs (ver.2.4.7) when I log in as an agent. In the Agent Ticket Search Result page I'd rather see these fields: Ticket Create Time Close Time From State Ticket Agent Customer ID Than: Tcket Age(!!!) From State Ticket Agent Customer ID In versione 2.3.4 I've got the AgentTicketSearchResultShort.dtl file (in Program Files\OTRS\OTRS\Kernel\Output\HTML\Standard) and I edited this without success :-( . In 2.4.7 version I haven't found any .dtl file to edit. Anyone can help me? Thanks, Alessandro
