Permit in PM Order

Hi Gurus

We have controlled the total cost in PM order in order type PM01 by applying the permit method, but now we have found the users can override this control by the method given below.

IW31 - While creating the order the user enters the component "ABCD" with qty 5 nos. The order value exceeds the amount in permit specified .

The user then changes the qty to 2 and now the value of the order is within the specified permit limit and the system allows the user to release the order. After releasing the order and without saving the user goes back to the component tab and changes the qty to 5 nos and saves the order.

Even though the order is released , and the qty is changed, the system should check the permit value and should not allow the user to save

the order.

Is there any method to over come this issue. Pls help

Regards
