HI Chandu,
I did as you suggested and added _SYS_BIC, but am unable to give privileges on the right as it is greyed out (see attached screenshot). I also tried to run the following SQL, but it won't let me:
GRANT SELECT ON SCHEMA _SYS_BIC TO _SYS_REPO WITH GRANT OPTION;
Could not execute 'GRANT SELECT ON SCHEMA _SYS_BIC TO _SYS_REPO WITH GRANT OPTION'
