Security for BW on Enterprise HANA deployment scenario

Hello,

While exposing HANA views to BW through Virtual info-provider & mapping BW info-objects to HANA attributes, I can achieve security restrictions through BW Analysis authorizations.

And, there is no need for a named BW id same as BW reporting user in HANA.

Question -> Which HANA DB user is used to pass the views data from HANA database to BW ? Is it SAP<sid> ?

Thanks,

Ravi
