How can we save Purchase Order amendment if error ‘Purchase Order quantity exceeds indent quantity’ occurs ?

Cause:
System shows the message ‘PO quantity exceeds indent quantity’ if the quantity amended is more then the indent quantity. Sometimes users save a Purchase order which is unconfirm with same indent numbers hence the system shows the error ‘Quantity Exceeds’.

Solutions:
Users need to ensure that quantity amended does not exceed the indent quantity. Or if an unconfirmed Purchase order is existing for the said indent then users can remove the line items from details of the unconfirmed Purchase order and save. Then save the record which showed the error of quantity exceeded.
