The same opening is a two-way order, that is, multiple orders are sold and empty orders are sold at the same time. This is called locking the position! Generally, warehouses will be locked in a passive situation, especially if the lock is not correct, which may lead to bilateral losses. Therefore, we should pay attention to opening the opposite warehouse receipt at the same time. If more than one order is sold, the corresponding deposit will be deducted, and so will the empty order. Deduct the corresponding empty bill deposit!
