Thanks,
In wizard enter quantity, check the quantity how much previous entered and get the different quantity is more then zero(we can say <code>remaining_qty</code>). If more then zero then need to check that <code>remaining_qty</code> is available on hand (from product template, we can say <code>available_qty</code>)). If not on hand throw the warning message.
