To change the value of the Lost column to pull from the Total Detail Amount instead of using the default value, you should edit the existing forecast.
The steps involve removing the existing Lost column and then adding a new calculated column that can reference the Total Detail Amount. This approach allows you to customize the forecast layout to meet the sales manager's requirement effectively.

Explanation:
1. Open the Quick Find View.
The Quick Find View controls what records are shown when users search for opportunities.
2. Delete the filter criteria Status "Equals Open."
The current filter is restricting search results to only open opportunities.
3. Change the filter criteria to Status "Does Not Equal Open."
This ensures that both open and closed opportunities are included in search results.

In Dynamics 365 Sales, unit groups define how products are sold in different quantities. The base unit is the smallest unit of measure in a unit group. Since customers now want to buy widgets individually, the smallest unit (Each) should be set as the base unit for all other units (Box, Case, and Pallet).

Choose the table with the most complete and reliable profile data about your customers: The primary table should contain the most accurate and complete information to serve as the foundation for matching records across different sources.
Choose the Dynamics 365 contact table when this is available as the data source: The contact table in Dynamics 365 is a logical choice for the primary table when it's available because it likely contains the core customer profile data that can be unified with other data sources.
