Hi Experts,
We have a UWL implemented in our SAP EP 7.31 portal.
It fetches work items from a back end system which is connected by a RFC destination.
It is seen that users have to hit the refresh button in UWL more than once to get the actual list.
When I checked the logs, found the following connectivity error to back end system:
"

But when I pinged the destination, it shows successful connection established.
Is there any option that I could try.
