Explanation
The time series projection feature in Tableau CRM for manufacturing provides data insights by tracking product growth trends. It uses historical data and machine learning to forecast future product demand and revenue. You can use this feature to analyze how your products are performing over time, identify seasonal patterns, and compare different scenarios. You can also adjust theforecast parameters, such as confidence interval, seasonality, and projection period, to suit your business needs.

To load data into Manufacturing Cloud, you need to follow a specific order of operations to ensure data integrity and avoid errors1.
The order of operations is based on the dependencies and relationships between the objects in Manufacturing Cloud1.
The recommended order of operations is as follows1:
Load Accounts, Contacts, and Products first, as they are the base objects that other objects depend on.
Load Sales Agreements next, as they reference Accounts, Contacts, and Products, and are used to track run-rate or long-term negotiated business.
Load Orders last, as they reference Sales Agreements, Accounts, Contacts, and Products, and are used to track actual business transactions.
The other options are incorrect because they do not follow the recommended order of operations and may cause data integrity issues or errors.

According to the Salesforce Manufacturing Cloud documentation, to create a new custom metric on the Account product period forecast component, you need to create a custom field on the Account Product Period Forecast object and another custom field on the Account Product Forecast object. Then, you need to map both of these fields in the Account Forecast setting page. This will allow you to add the custom metric to the Forecast tab of an account and track it along with the standard metrics1.

Explanation
To set up Tableau CRM for Manufacturing, an Admin needs to have the Manufacturing Einstein Admin permission set and the Manufacturing Analytics Admin permission set. The Manufacturing Einstein Admin permission set grants access to the Manufacturing Einstein features, such as Account Forecasting and Account Manager Targets. The Manufacturing Analytics Admin permission set grants access to the Manufacturing Analytics app and its dashboards, such as Sales Agreement Performance and Account Health1.
