ticket visibility in WEBUI search (VAR)

Guys,

We are using SOLMAN 7.1 SP08 and we would like to restrict ticket visibilty for end users in the WEBUI. Now when searching with the end user they can see all tickets, also those from other cusomers.

I have assigned object SM_SDK_IBA (SMIBASDISP = USERS_OWN) to the test user, but I can still find all tickets.

Can anyone give me some pointers?

Thanks,

Philip
