Hi,
The same question has been already raised in this topic
Even though original poster claims that he/she managed to set it up, we never seen details about how it was done.
My statement is that there's no such thing as "UWL Real Time Refresh" even though SAP uses this term. The only real time refresh is done for completed items in UWL, however when it comes to pulling new workitems into UWL it can only be optimized for near-real time experience by configuring UWL refresh treshold and enabling delta pull mechanism.
