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.
Do you mean that in your development system you do see employee details but in QA you do not? If that's the case it may be failing an authorization check to see employee data. Compare your authorizations between the two systems or run a trace in QA to see what authorization check you may be failing.
