Yes, i've also mentioned another thread, where the exact required steps are given. i am just copy pasting the solution content of the thread by adding some additional comments for your reference:
1. create a role in the .xsprivileges file // create the privileges file: ".XSPRIVILEGES"
{
"privileges": [{
"name": "Execute",
"description": "Basic usage privilege"
}]
}
2. add the sql object permission into the user <role filename>.hdbrole: //create the role file "<role filename>.hdbrole"
sql object <account>.<package>::Person: SELECT, INSERT, UPDATE,DELETE;
sql object <account>.<package>::PersonId: SELECT; /* sequence for key generation */
3. execute // grant role to your user
call HCP.HCP_GRANT_ROLE_TO_USER('<account>.<package>::<role filename>','<user>')
Or use this:
call "HCP"."HCP_GRANT_ACTIVATED_ROLE"('XXROLENAMEXX');
CALL "HCP"."HCP_GRANT_SELECT_ON_ACTIVATED_OBJECTS"
4. execute the below if you make changes to the roles
CALL "HCP"."HCP_SYNCHRONIZE_ROLES"
