Order exceeded the quant. class

Hi Experts,

We are facing a serious problem please help!

There are some clients with class 1 in xd02 whose order quantity should not exceed 40.

If exceeded 40 and we try to save it displays an error message Order exceeded the class in VA01.

My orders are created in Portuguese.

This is working fine but the problem after this error when we try to go back and click no to the order it's still saving the order.

Yes No Cancel buttons.

When i go to VA05 and check the open orders for this customer am able see the order with quantity more than 40 which we can't save with error message.

Can anyone help me to resolve this issue.

Thanks & Regards

Srikanth
