Modeling in HANA studio with BW tables

Hello,

We have built 2 write optimized DSOs in BW7.3 on HANA.

Now i can see DSO tables in HANA DB under BW user schema and we need to do modeling with these DSO tables in HANA modeler.

Questions:

1. Under BW user schema i can see DSO active tables, after opening the table the Execute(F8) button is in disabled mode, how to enable this execute button-does it require any additional previleges. How to see the data content for DSO table in HANA studio?

2. Can we use DSO tables for HANA views modeling --> Creating Attribute, Analytic and Calculation view?

3. To use these BW-HANA models in BO, any special configuration to be done in HANA?

Thanks,
