Hi Bharani,
Please check what Arijit is mentioning. If you have data that is visible in CAT2 and you cannot see that data in Fiori Timesheet then 90% is because of system connection settings.
One quick way to check this is by putting an external breakpoint for the fiori user in the method SRA002_TS_WORKCALENDAR_GET Line 62
In the debugger check the value of the variable - SY-UNAME. It should be the logged in fiori user if not then this means that's the RFC connection settings is not correct.
Note: When setting an external session breakpoint it should be for the fiori user, you can do this via Utilities > Settings
To fix this:
1. in your gateway system go to transaction SM59
2. Navigate to the RFC connection (ABAP connections) which points to your ERP/ECC system.
3. Set the flag Current User and Trust Relationship as Yes
.
If you are still facing the issue:
1. Check if CVR parameter is set in User Profile of the Fiori user.
2. Check if pernr is attached (InfoType 0105 SubType 0001)
3. Do you get an error popup on the first screen as soon as you launch the application? If so, what is the error.
If you are still facing the issue please reply, we will see what we can do.
Best regards,
Sagar
