Currently , the generated organizationalentity table only has the id as its primary key. If I have to insert a group into this table but a user record with the same name already exists in this table ( it may due to task service API currently will automatically insert organizationalentity record if no such records are found ) , duplicate primary key exception occurs during the insertion.

It is more flexible if the organizationalentity table has a composite primary key which consists of both id column and dtype column (discriminator column) .
