HANA optimized Infoproviders in BW(7.4) on HANA working with BPC10.0 or 10.1

Hello Experts,

I am working in a scenario where we have BW 7.3 and BPC 10.0. For any data manipulations in BPC info providers we write BADI logic using UJ framework Classes and Methods to change and write back to BPC generated Info provider data.

moving forward, we are planning to go for BW on HANA therefore my questions

1)

Now BPC generates, Realtime info providers in the backend when a Model is created in BPC.

To utilize the full potential of BW on HANA, will I be able to change those Realtime info providers to Hana optimised info providers ?

2)

For any Complex calculations we need to perform on the data in the BPC info providers, we now use BADI logic, I want to know in BW on HANA with BW info providers as HANA optimised, can I do those calculations using Sql script.

Or is Sql script only for HANA Views ?

Please throw some light on this

Kind Regards,

Krishna
