Can new entity of many-to-many relationship generate new entity?

[wannabesmart]

Relationship between Item entity and Supplier entity is many-to-many, then this relation generates a new entity called Purchasing. Then the relationship between Purchasing entity (new enity) and Item entity is many-to-many. What I'd to ask is can the relationship with a new entity generate a new entity (again)?




Hope you understand what I mean.
Thanks in advanced

Nope, don't understand what you are trying to accomplish.

Item and Supplier have many-to-many relationship. Purchasing is a 'junction' that documents associations between Item and Supplier.

Exactly what 'new entity' do you want to generate?
