A dispute is a discrepancy between what has been ordered and what has been received at the time the passed for payement is entered.
The discrepancy may concern the unit price or the quantity of the item. When this discrepancy (associated with a reason such as broken, missing or price refused) is entered, a dispute with the supplier is generated.
This is also referred to as a declared dispute. It is not possible to enter an amount or quantity greater than the original order.
For example: I order 10kg of Daucy green beans, and on delivery I discover that only 8kg has been delivered. The system therefore creates a dispute for 2kg, for which I enter the reason "missing".
