Hello there, When building a large CMDB, it's neccesary to create sub-classes inside classes. Since OTRS creates sub-queues and sub-services on database using the parent::child syntax, it's easy to think the way sub-classes on CIs should be done the same way so we created a Servers class and then Servers::Windows and Server::Unix sub-classes. All good till then but unfortunately when watching them on otrs/index.pl?Action=AgentITSMConfigItemall of them are shown on the same level, which is a bit of a pain when dealing with a huge structure as our current customer's one. Is there a way of showing sub-classes on Configuration Items like sub-queues are shown? Any help on this is much appreciated. Leonardo Certuche www.itconsultores.com.co Medellín, Colombia
