The order locally checkbox enables a scenario where the requisitioning business unit outsources only the business processes related to negotiating and administering the agreement with the supplier, but still owns the business processes related to creating and administering its own purchase orders for commodities it is buying off the agreement.
If unchecked, the client requisitioning business unit outsources all of these business processes.
You can use the order locally checkbox to configure what business processes the requisitioning business unit will outsource.
