Configuring Path by checking the key field required checkbox can ensure that opportunity stage reports always contain the data managers expect, as it makes certain fields mandatory for users to fill in before they can move an opportunity to a specific stage. Path is a feature that guides users through a set of stages for a particular business process, such as opportunity sales stages. Users can see key fields and guidance for each stage, and update them as they progress along the path. Marking fields as required on the page layout can also ensure that opportunity stage reports always contain the data managers expect, as it prevents users from saving an opportunity record without entering values for those fields. Page layouts control how fields, related lists, and other components are arranged on a record detail or edit page.
