Member Acces Mode Feature does not appear (1.4)

Hi,

I am starting to use SAP DS 1.4 SP0 Patch2 (14.0.5) using UNX Universes as data source to buidl the queries. I have created some data sources but when DS shows the context menu of a dimension element the option "Memeber accces mode" does not appear.

Some one knows whys this feature is not longer appearing? It is possible to use this feature when using UNX-based queries?

Thanks
