Issue with Transactional iViews

Hello Gurus,

I am working on Migrating Content from 7.0 to 7.4. We have SAP ECC Transaction based iviews and we got basic functionality working in 7.4, but there are some limitations in 7.4

1) Created iView from Remote source like below and on the Transaction iView back button is taking to blank screen than easy access menu of user.

Creating iViews from Remote Sources - Portal - SAP Library

I tried below approach as well... but seems working in same way.

https://<system:port>/irj/servlet/prt/portal/prtroot/com.sap.portal.appintegrator.sap.Transaction?GuiType=WinGui&S…

Is it a limitation from 7.4? Can you please help me with this?

Thanks,

SK
