Hello Sushma,
In order to see the roles in your roles table,
1) first you have to activate your role file (.hdbrole) from the code, if you successfully activated your .hdbrole role file you can see the file with small gold color, or else, it will show a small red wrong symbol to file.
i hope you went through it,
2) Now run the command to grant select on activated object which should be run every time you modify a file activate it.
CALL "HCP"."HCP_GRANT_SELECT_ON_ACTIVATED_OBJECTS"
3)Make sure your hdbrole file point to your personal schema it will be named as
catalog schema "NEO_****" : SELECT, EXECUTE, CREATE ANY;
4) and make sure your hana cloud name is not more than 7 characters trial hana system cannot work properly with name more than 7 characters.
let me know if you solved or not.
regards,
Prashanth.
