I have this saved in my snippets that seems to do a good job of generating explicit permissions;

does this produce the results you are after for a single database?

select sys.schemas.name 'Schema'

, sys.objects.name Object

, sys.database_principals.name username

, sys.database_permissions.type permissions_type

, sys.database_permissions.permission_name

, sys.database_permissions.state permission_state

, sys.database_permissions.state_desc

, state_desc + ' ' + permission_name + ' on ['+ sys.schemas.name + '].[' + sys.objects.name + '] to [' + sys.database_principals.name + ']' COLLATE LATIN1_General_CI_AS

from sys.database_permissions

join sys.objects on sys.database_permissions.major_id = sys.objects.object_id

join sys.schemas on sys.objects.schema_id = sys.schemas.schema_id

join sys.database_principals on sys.database_permissions.grantee_principal_id = sys.database_principals.principal_id

--WHERE sys.database_principals.name = 'your_user_or_role'

order by 1, 2, 3, 5
