SAP BI report does not pick up portal theme

Hello All,

Portal version : 7.4

SAP BI Version : 7.4 SP10

I have created a SAP BI system object (attached screenshot) and a SAP BI iView (codelink = com.sap.portal.appintegrator.sap.BWReport) screenshot attached.

Portal and BI are running on different servers.

When I open iView, it is not picking up Portal theme. Reports are shown in SAP Tradeshow theme.

In Portal, we have 3 themes, (3 different desktops depending on set of users).

Hence, we cannot just download & give any one theme to BI team.

It is mandatory that portal dynamically sends the theme to BI side.

Any idea how is this possible?

Thanks & Regards,

Amey
