SAP BW 7.0 Authorization problem


we have the following problem on our project and I hope someone can help us!

First some input:

We are working with Net weaver 2004s (SAP BW 7.0) and my user has the following profiles S_A.SYSTEM and SAP_ALL. We have loaded the following data model from BC: C0-OM-CCA and are working with info cube 0CCA_C11 (Costs and Allocation. It was possible to load data records from R/3 without errors.

Now the problem:

If we want to see the content of our info cube (without any selection) we get the following error messages:

Message no. EYE007: You do not have sufficient authorization

Diagnosis: You do not have sufficient authorization for the requested data records.

Procedure: Either select other data records or get the required authorizations from your administrator.

Message no. RS_EXECPETION251: User XX does not have authorization for Info Provider 0CCA_C11

No further Information.

Does someone know this problem and can help us? Maybe it is really a bug or it has something to do with the new authorization concept of SAP BW 7.0

Thanks for your help and support!
