Hi,
its generates SIDs, but along with alpha there two more issues thru star schema, due that sap came with extended stars schema where its over comes thru those problems.
Problems at start schema,
1.Due to alpha numeric values at cube level, slow performance
2. Master data is limited(now one dim can have 248 master data objects)
3. Master data not reusable(now its out the side the info cube and reusable)
Thanks
