Hi,
I have configured SAP ECC Transaction to Portal through SSO using SAP GUI for HTML.
While testing it on the Portal in latest browser IE10 and IE11 with compatibility mode on, it just loads the screen from remote.
But while clicking on any button(like date selection) to provide input for transaction, screen goes on loading for a long without any error.
The same works in the Same Browser version, where the portal is hosted.
So, please let me know if you have any suggestion to correct this.
