youdao

The data handler detaches the logical attachment from the Order data object and calls the Claim check service to check in the logical attachment.

数据处理程序将逻辑附件从Order数据对象中分离出来，并调用Claim Check服务来签入逻辑附件。

youdao

When the logical attachment is returned by the Claim Check service, the data handler attaches the logical attachment to the ShipmentRequisition data object.

当 Claim Check 服务返回逻辑附件时，数据处理程序将逻辑附件附加在 ShipmentRequisition 数据对象上。
