Hi Florian,
As per your suggestion, I did try activating the HANA authorization trace and I found that user generally don't have EXECUTE rights on any procedures under _SYS_BIC schema, as it is a runtime generated objects.
Hence, after all trial and error, my findings says we cannot perform EXECUTE directly on run time generated procedures under _SYS_BIC schema.
The only way to get the solution working is to write a select statement on the view directly. Below is the screen shot of the final solution.
Let me know if you have any other thoughts 
Regards,
Anup
