I created 1 sales order "OR" and then created delivery for this order. After creating delivery if i do some changes in delivery quantity like if i increase or decrease order quantity in delivery document, System should generate error message that over delivery is not allowed. But in my case my system do not generate any error message and also order should updated automatically but it is not happening
Similarily when i add one more item in delivery, order should gererate error message and order also should updated but my order do not show any updation.
Can any one please tell me where i should do changes in customisation.
