Hi Anusha,
This error is related to OBN (Object Based Navigation) but not pertains to UWL actually. Please firstly check Note#1386141 - There is no iView available for system "XYZ", object "ABC" see if it applicable.
In addtion, make sure the following notes from PA-PD-PM component are implemented in case they are applicable:
Notes:
1408243 - Configuration for object-based navigation.
1416756 - OBN Configuration in Performance Management.
For further investigation:
1. What is the OBN target that the user expects to be launched as result of the OBN action ? Let me know the target iView name and its full screenshots of iView Editor in the Object-Based Navigateion view.
2. Ensure the relevant operation appears in the table.
3. Please refer to Note#1558903 to collect a HttpWatch trace while reproduce the issue again, save the trace as .hwl format and attach here.
Regards,
Herman
