Explanation
Out-of-the-box Manufacturing Actions are predefined actions that you can use in Process Builder and Flow Builder to automate common tasks related to Manufacturing Cloud. There are two out-of-the-box Manufacturing Actions that can be performed in Process Builder and Flow Builder:
Mass Update Account Forecast: This action allows you to update multiple account forecasts at once based on specified criteria. You can use this action to change the status, target, or owner of account forecasts in bulk1.
Mass Update Sales Agreement: This action allows you to update multiple sales agreements at once based on specified criteria. You can use this action to change the status, owner, or period group of sales agreements in bulk2. References: Mass Update Account Forecasts, Mass Update Sales Agreements

: The organization should leverage Partner Visit Management functionality to fill the gap. Partner Visit Management is a feature of Salesforce Manufacturing Cloud that enables manufacturers to collaborate with their channel partners on sales and service activities. With Partner Visit Management, manufacturers can create and assign visit plans to their partners, track their progress and performance, and provide feedback and coaching. Partners can access the visit plans through the Manufacturing partner site, which is a predefined template for Experience Cloud sites. The Manufacturing partner site also allows partners to view and update sales agreements, forecasts, and account information, as well as access resources and training materials. By using Partner Visit Management and the Manufacturing partner site, the organization can support its channel partners by providing functionality, insights, and data, as well as working closely with them to plan their work.
