Hello everyone,
I posted an article Development and Extension Guide - Launch SAP® GUI Transaction from WebClient UIwhich is an extension guide on how to integrate business transactions running in SAP GUI for Windows into the WebClient UI. Please keep in mind that this article provides guidance and tips to customers and developers who would like to take advantage of this functionality. At the end of the day, if you require assistance, it will be a consulting engagement. Best of luck.
