Explanation
The Manufacturing agreement Performance and Manufacturing Product Performance dashboards are prebuilt analytics dashboards that show key metrics and trends for sales agreements and products. You can embed these dashboards in any manufacturing cloud page without setting up filters, as they automatically filter the data based on the record context. You can also adjust the component height to fit your page layout. However, you cannot embed these dashboards in a Visualforce page or a standard Salesforce dashboard.

A sales agreement can be renewed only when it is in the renewal period, which is defined by the number of days before the end date of the agreement.
A sales agreement that is expired or approved can be renewed if it is within the renewal period. However, a sales agreement that is activated cannot be renewed, because it means that the agreement is currently active and has not reached its end date or renewal period.

Account Based Forecasting and Sales Agreements are two Manufacturing Cloud functions that should be configured to have a complete picture of both run-rate and net-new business. Account Based Forecasting allows you to forecast your sales revenue based on the account level, rather than the opportunity level. This gives you more visibility into the demand from your existing customers, as well as the potential from new customers. Sales Agreements allow you to manage the sales lifecycle of your long-term contracts with customers, including pricing, volumes, and order realization. This helps you to track and fulfill your run-rate business, as well as to identify and capture new business opportunities within your agreements.

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.
