Manage Incidents Web dynpro app not fetching employee details

Hi,

In Fiori Launchpad in Manage Incidents app I am unable to fetch employee details in Task tab, but in deb system I am unable to fetch employee details. But in QA I am not getting employee details.

As its web dynpro app, I am not able to find where data is coming from.

Is issue form front end system (.i.e from Fiori ) or its backend issue.

Thanks...
