Hi Suresh,
I meant when you open a cube you will have the dimension folders like Dimension 1, 2 etc but actually no dimension tables are created in the background except the package dimension table.
The HANA optmized Infocube does not have dimension tables between the fact and the SID tables. The fact table is directly linked to the SID tables of the characteristics used in the cube. Only exception is the package dimension which is used to keep track of DTP requests in the cube and mainly used/accessed while compression of cube data.
Best regards,
Edwin.
