LSA++ Virtual Layer between ADSOs and Composite Provider

Hi All,

What is the recommended approach for building the Virtual layer between the top layer of ADSOs and the Composite provider?

In earlier BW versions, we used to create multiple layers of DSOs (Inbound/Transformation/Harmonization ets.) to incorporate the data transformation logic.

However, with LSA++ the recommendation is to reduce the number of Data marts and use only Staging layer and Virtual layer (Picture below). In that case, how do we implement the complex business logic we applied within all the transformations?

Is it recommended to use CDS Views or HANA Views on top of the Staging ADSOs to apply the business logic? Or use multiple layers of ADSOs?

Thanks a lot in advance.
