Hi @einas.ibrahim,
Instructions provided in Activity '3.3.7.2 Add DCA to INV01 Inventory Ordering' seems confusing as both line saying that result show when Submit Purchase Order Request is NOT checked and checked.
I think it could be no results when Submit Purchase Order Request is NOT checked and show result when checked as per Anaplan 'Check your Work' screenshot.

Please guide me if i interpret it wrong.
Thanks
Abhishek
