It doesn't matter what values you use for the input, with the exception of orderNumber.

为输入使用什么值并没有关系，但 orderNumber例外。

The value of orderNumber in the Order business object, which is used as input for both operations, has been set as the correlation ID.

Order业务对象中的orderNumber值（它用作这两个操作的输入）都已经被设置为关联ID。
