Hi Radesh,
I had a similar problem and I could solve it in this way:
In my case the issue was caused by service /IWFND/SG_MED_CATALOG which reads annotation information for other odata services.
- Go to transaction /IWFND/MAINT_SERVICE
- Filter for service /IWFND/SG_MED_CATALOG (technical service name) Version 2
- Check the system alias area and make sure that NO system alias is assigned for this service (not even LOCAL!).
Try again!
Regards,
Martin
