The purchase order has been deleted, but the inventory quantity has not decreased accordingly. How can this problem be solved?

A purchase order doesn't directly affect inventory quantities if you delete it, Hina.

Deleting a Purchase Order (PO), even if it is a non-posting transaction, does not affect the inventory quantity. Non-posting transactions do not impact the inventory levels until they are converted into posting transactions, such as bills or invoices. Therefore, if the PO is deleted before any posting occurs, the inventory quantity remains unchanged.
