Display a sap portlet in SharePoint 2013 page

I am trying to display the SAP workitem portlet in a SharePoint 2013 page. I tried using iframe or object tag but it just keep going into infinite loop and refreshing. In some firefox browser version, it displays the meesage : a possible cross frame scripting attack has been detected and please refer to SAP note to 1651004. We have verified the nots and ensure the settings are done but we are still having the infinite loop in the iframe area (to SAP workitem portlet) in SharePoint 2013 page. Can someone advise how I can display the SAP workitems portlet in SharePoint page?
