Do you know how configure WEB UI?
There is a special config files which allow you to add fields you need to web client interface!
Please, give some more information about you problem!
Thanks for the reply. Yes I know how to add OOB sub-entities and fields in the Detail View through XML config files but if I create any custom sub-entity than they don't appear in the detail view even if I add the custom sub-entity in XML config file. Any Idea how to add a custom sub-entity in the Detail View ??
