If Enable Reduction Orders is later disabled, the “Create Reduction Orders” permission is hidden from all profiles or permission sets, but no data is hidden. Your sales team can’t create or activate reduction orders, but they can view and edit existing ones. If you disable reduction orders, disable the record types and page layouts specific to reduction orders. If you aren’t using record types, remove fields specific to reduction orders from your page layouts. These include Original Order
and Reduction Order
on the Order object, Original Order Product
and Available Quantity
on the Order Product object, and any custom fields.
