Looks like it’s a big week for EP/MOSS interoperability. Yesterday the SharePoint Team released the WSRP Toolkit for SharePoint 2007 and today the SAP interoperability folks at Microsoft released a new white paper explaining the limitations of the IView Web Part and how to get around those.
I’ve encountered the infinite refresh loop issue described in the introduction of the white paper. The IView Web Part uses an IFrame to display the iView from SAP, but sometimes the web part will go into an infinite loop. This can now be addressed by developing a simple custom web part using an HTML object tag for displaying the iView. Simply follow the guidelines in the white paper.
