I want to create a many2many relation in res.partner (self related). This relationship needs to have attributes.

For example: PartnerA is 'manager' of PartnerB. PartnerB is 'owner' of PartnerB1. PartnerC is 'business agent' of PartnerA. ....

The type of relation (enclosed by '') will be a new model partner_relations.

How can I implement this?
