Note: - The Quantity and TotalCostPool elements are read-only. They cannot be explicitly set via the Items endpoint. The only way to change the quantity and value of tracked items is by creating accounting transactions. - Increase the value and quantity of a tracked item by creating purchase transactions (ACCPAY Invoices or SPEND BankTransactions) and decrease the value and quantity of tracked items by creating sales transactions (ACCREC Invoices or RECEIVE BankTransactions).
