求翻译：我所说的“planning date of dispatch”，不是预计装运日期，而是预计车辆到达工厂的日期。卡车数量和车牌号必须要提前告诉我们，因为我们要提供给工厂。工厂只有接到我们的指示才会开始装货。如果你没有提前告诉我们而是直接到达工厂，这种情况下工厂是不会给安排的。我们得到这些车辆信息之后，如果有的车辆因为一些原因没有准时到达工厂，那么工厂会负责装运其他车牌号相符合的车辆。这就是为什么要求你加上这两点的原因。是什么意思？

Truck number and license plate number must tell us in advance, because we want to provide to the plant. We only received the plant will begin loading instructions
