Hi Rekha,
Please assign a value to content_vendor in the file indexserver.ini and then this should be resolved.
To do this please follow the below steps.
1. Open the Configuration tab in the Administration window in HANA Studio.
2. Double click on 'content_vendor' under 'repository' in 'indexserver.ini'.
3. Type sap.com or anything what you want in 'New Value', then click Save.
Regards,
Vijay
