Mass Delete of Customer Orders AX2009

Hi,

I Need to delete 1500 customer orders from AX 2009

They are all at an open status and have no attached transactions, so deleting them one at a time is not issue, apart from the time required.

I have seen how you can select multiple orders and hit the delete, but it comes up with a warning on each order to ask "Do you want to delete the lines". I can click past this but would have to do so 1500 times.

Is they any way of surpressing this warning message ?

Thanks Rob
