No interfaces visible in ECC's SPROXY for user A, while visible for user B

Hi guys,

we're facing a strange issue.. One user can see wothout any problems all available intarfces in the ECC's SPROXY, but another one doesn't. This obviously can't be then a problem of a connection, and what is even more interesting, both users have the same roles.

Any idea what could be wrong there?

Thanks a lot,

Peter
