When you change the forecast formula, the existing forecasts are deleted and new forecasts are generated using the updated formula. This applies to all forecasts, regardless of their status. Therefore, the correct answer is C. Regeneration of all forecast(s). References: Build Formulas to Calculate Forecast, Configure Forecast Metrics and Formulas

Validating the functionality against business process flows is a key step in the implementation or system update of Salesforce Manufacturing Cloud. It helps to ensure that the system meets the business requirements and expectations of the stakeholders, and that it can handle the various scenarios and use cases that may arise in the manufacturing industry. By validating the functionality, you can also identify and resolve any issues or gaps that may affect the system performance, usability, or security. Additionally, validating the functionality can help you to document and communicate the system changes and benefits to the end users and other parties involved in the project. References: Implementation Guide, System Updates

 You can recalculate payouts for closed periods in two situations: when the member benefits change due to changed requirements, or when the member submits transactions after the payout period is closed, or there is an error in the payout calculation. In both cases, you need to modify the payout records and run the rebate flow again to recalculate the payouts. The first method is to recalculate payouts due to changed benefits, which means that the benefit structure and terms have changed after the payout was calculated for a period. The second method is to recalculate payouts with no charge in benefits, which means that the benefit structure and terms have not changed, but the transactions or the payout calculation have changed. References: Recalculate Payouts for Closed Periods, Rebate Management

On the Forecast settings page within Salesforce Manufacturing Cloud, actions such as updating the forecast start period, forecast adjustment period, and forecast formula will trigger the regeneration of all the eligible accounts that meet the forecast generation criteria. These updates necessitate a re-evaluation of forecast data to ensure that the forecasts remain accurate and reflective of the latest business conditions and settings. This regeneration process is integral to maintaining the integrity and relevance of forecast data, facilitating effective planning and decision-making based on the most current information .

The account product period forecast record limit is the maximum number of records that can be stored in the Account Product Period Forecast object, which represents the quantity and revenue information of products for a particular time period of the forecast rolling period1. The default limit is 9 million records, but it can be changed by the admin2. If the org hits the limit, new products cannot be added to account forecasts, and new products are not added when recalculating a single account forecast or recalculating all account forecasts2. This means that the forecast data will not reflect the latest changes in the product portfolio and may affect the accuracy of the forecast. The add products option will still appear on the agreement terms tab, but it will not work if the limit is reached. New products added to account forecasts will be included in recalculations, as long as the limit is not exceeded. References: Considerations for Working with Manufacturing - Salesforce, Define Account Forecast Settings Unit | Salesforce Trailhead Module, Advanced Account Forecasting with Manufacturing Cloud | Salesforce, AccountProductPeriodForecast | Manufacturing Cloud Developer Guide | Salesforce Developers

To allow the Service Agents to access the latest updates to a sales agreement when navigating from the customer interaction related to the account, the Manufacturing Cloud consultant should recommend adding the Sales Agreement related list to the Account record page in Lightning App Builder. This way, the Service Agents can see the sales agreements associated with the account and view their status, terms, and schedules. The Sales Agreement related list is available for the Account object by default and can be added to the Account page layout using the Lightning App Builder. References: Sales Agreements Overview, Customize Record Pages with the Lightning App Builder

 These three user types can be selected to receive credit for an order in the Tableau CRM configuration wizard when calculating actuals against account manager targets. The configuration wizard guides users through the creation of an app from the Analytics for Manufacturing template and allows them to customize the data and settings for the app. One of the settings is to choose who gets credit for the orders, which determines how the actual revenue is attributed to the account managers. The user can select one of the following options:

Account Owner: This option credits all orders to the account owner’s actual revenue, regardless of who owns the order. This is useful when the account owner is responsible for the overall relationship and revenue of the account.

Order Owner: This option credits all orders to the order owner’s actual revenue, regardless of who owns the account. This is useful when the order owner is responsible for the individual order and revenue of the order.

Other User: This option credits all orders to a custom user’s actual revenue, based on a custom lookup field for a user on the account. This is useful when there is a different user, such as a sales engineer or a partner, who is responsible for the order and revenue of the order.
