Change AO datasource using Replace System feature

Hi,

I am trying to switch the HANA datasource of existing workbook from the production to QA using "Replace System" feature on AO2.7 sp8.

The HANA datasources are provided via BI server using SAML/SSO. My issue is when I logon to BI server, i don't see the list of HANA datasources configured for this BI server in my AO client. Where this information is getting from?

BI development environment (VID), i should see VPS, VQA, VDV, VPR, VTO etc but i only see VTO. Thank you for your input in advance. Aya
