To quickly view which role have what rights, You can use this SQL query:
SELECT DISTINCT
r.Name
,COALESCE(e.OriginalLocalizedName, e.Name) AS EntityName
,CASE p.AccessRight
WHEN 32 THEN 'Create'
WHEN 1 THEN 'Read'
WHEN 2 THEN 'Write'
WHEN 65536 THEN 'Delete'
WHEN 4 THEN 'Append'
WHEN 16 THEN 'AppendTo'
WHEN 524288 THEN 'Assign'
WHEN 262144 THEN 'Share'
ELSE 'None'
END AS [Privilege]
,CASE (rp.PrivilegeDepthMask % 0x0F)
WHEN 1 THEN 'User (Basic)'
WHEN 2 THEN 'Business Unit (Local)'
WHEN 4 THEN 'Parental (Deep)'
WHEN 8 THEN 'Organization (Global)'
ELSE 'Unknown'
END AS [PrivilegeLevel]
,(rp.PrivilegeDepthMask % 0x0F) as PrivilegeDepthMask
,CASE WHEN e.IsCustomEntity = 1 THEN 'Yes' ELSE 'No' END AS IsCustomEntity
FROM Role AS r
INNER JOIN RolePrivileges AS rp ON r.RoleId = rp.RoleId
INNER JOIN Privilege AS p ON rp.PrivilegeId = p.PrivilegeId
INNER JOIN PrivilegeObjectTypeCodes AS potc ON potc.PrivilegeId = p.PrivilegeId
INNER JOIN MetadataSchema.Entity AS e ON e.ObjectTypeCode = potc.ObjectTypeCode
ORDER BY r.Name, EntityName
