Explanation
To export Account Based Forecast data to use in their Demand Planning system, the user can use standard Salesforce Reporting to create a report with only forecasting quantity data, including any sales team adjustments. To do this, the user can perform the following actions:
* Create a report using the standard report type of 'Account Forecasts with Product Period Forecast'. This report type allows the user to access the data from the AccountForecast and AccountProductPeriodForecast objects, which store the forecast metrics for each account and product combination.
* Add the 'Adjusted Forecast Quantity' field from the 'Account Product Forecast' object to the report.
This field shows the forecast quantity after applying any adjustments made by the sales team. The user can also add other fields, such as account name, product name, period name, or forecast set name, to the report as needed.
The user can then run the report and export the data to a CSV file or another format that can be used by their Demand Planning system.

Explanation
When list views are selected for account forecasts, the account managers can generate forecasts based on the list view if they have one of these two permissions options: share list view with group of users or share list view with account owners. These options allow the account managers to see only the accounts that they have access to, and not all the accounts in the org. This way, they can create more accurate and relevant forecasts for their accounts. References: Create and Edit Permission Set List Views, Set Up Users and Permissions for Manufacturing Cloud

Explanation
When you change the team member hierarchy type for account manager targets, the status of all existing targets becomes Draft. This means that the targets are no longer active and need to be redistributed by the account managers according to the new hierarchy. The previous assignments and target values are not deleted, but they are not visible in the account manager targets list views or reports. You can still view them in the related lists of the account manager targets records. References: Choose Team Member Hierarchy for Account Manager Targets
