transfer order cannot be closed

We have a transfer order that the users increased and decreased the quantities and now the order cannot be closed.  This was done shortly after we went live and did not understand the problems this would cause.  The order is sitting with a quantity to be shipped and received and is causing us issues because it effects the MRP which continuously tries to satisfy this demand and it is an item that is used extensively, the open quantity is for 200.  Short of major database surgery is there any way to close this transfer order?

Thanks!
