Hi, 

    a CSP get some negotiated prices with a Customer for 1 offering. Then, an external company/partner wants to access the offering negotiated prices. How can this be done?

1. TMF 620 provides the catalog price for the offering. 
2. TMF 620 allows referencing an agreement
3. TMF 651 allows referencing a Product (ProductAgreementItem subclass) (productOffering -> A ProductOfferingRef. ProductOffering reference. A product offering represents entities that are orderable from the provider of the catalog, this resource includes pricing information.)

Should the agreement keeps the price alterations for that customer so we can get the negotiated prices (list prices + alterations)? kind of: 

1. Partner triggers a TMF 620 Get "productofferings" with specific ProductAgreementItem
2. Partner get back the negotiated prices as per the Agreement
