Yes, I tried it but couldn't make it work in my use case. The issue for me is that I need both schemas SCHEMA_A and SCHEMA_B exist in the same HANA instance. SCHEMA_A has the full dataset which makes the analytic views running slow. I want to create another schema SCHEMA_B which is stripped down version of SCHEMA_A and has at most 1/10 of data in it. I want to make the views point to SCHEMA_B instead of SCHEMA_A to improve performance.
When I tried to create a schema mapping between SCHEMA_A and SCHEMA_B, HANA complained that the authorizing schema SCHEMA_A already exists as a physical schema and didn't allow me to proceed.
Thanks,
