Cognos 10.2.1
Dimentional Pakage

Hello Cognos Expert!
We want to add 2 reports in CognosWorkspace.
the filter will be the product Item.
The reports will have the product Item in the context filter.
I tried it in Workpace and the filter works well.
The problem is that I do not see all products (we have aroud 2000).
I see a list of ~50.
I tried the work aroud _BusinessInsight_ but it does not seems to work.
Am I missing something? Is It possible to do in this Cognos version or another one?
Thanks in advance !
It would be very useful for my users.
