A sales agreement is a long-term agreement between a buyer and a seller to negotiate price and

volume of products. To create a sales agreement in Salesforce Manufacturing Cloud, you need to

have an account object that represents the buyer. The account object stores the information about

the customer, such as name, address, contact, industry, and so on. You can also associate a contact

object with the account to specify the person who is responsible for the sales agreement. Other

objects that are related to the sales agreement are sales agreement product, sales agreement

product schedule, sales agreement line item, and sales agreement

forecast. Reference: SalesAgreement | Manufacturing Cloud Developer Guide | Salesforce
