Introduction –

This article shows you the way to integrate Help Center feature into your Webdynpro ABAP application without SAP Knowledge Warehouse Setup in place.

The Help Center is available in a first version for applications of ERP 6.0 Enhancement Package 4. Its features will be improved and extended in future versions. Refer http://wiki.sdn.sap.com/wiki/display/Found/Help+Center to know more about Help Center.

 As per SAP help,
