SAPUI5 Application is not working in EP 7.01

Hi All,

I have SAPUI5 application developed and hosted in SAP ABAP Web Application server ( GW Server), this app is already integrated with SAP Enterprise Portal 7.01 ( SP15), It is working fine without any issue in Chrome Browser.

But NOT in IE11 from only Portal.

Note: the same application is working fine in IE11 by using direct app link from ABAP WAS, the problem is only when the UI5 application is called from Portal iview ( SAPUI5 iview) in IE11.

Please suggest what could be the reason behind this. is there any other way to run Ui5 application from Portal 7.01 in IE11.

Thanks
Sathya
