The Minimum Inventory field on the Sales Agreement Product Schedule object is used to store the minimum inventory quantity required for each product in a sales agreement. To make this field visible and editable on the Forecast grid, UC needs to add a custom Minimum Inventory field to the Sales Agreement Product object, which is the parent object of the Sales Agreement Product Schedule object. Then, UC needs to map the two fields using the Field Mapping tool in the Sales Agreement setup. This will ensure that the values entered in the Forecast grid are synced with the values in the Sales Agreement Product Schedule object. Finally, UC needs to add the Minimum Inventory field to the list of available metrics in the Sales Agreement setup. This will allow users to select the Minimum Inventory metric from the dropdown menu on the Forecast grid and see the values for each product and time period.
