無法完成呼叫以在此 Transaction 物件上建立上層 Enlistment，因為針對徵募指定的 Transaction 物件是該 Transaction 的下層分支。只有 Transaction 的根項目可以徵募為上層。

The call to create a superior Enlistment on this Transaction object could not be completed, because the Transaction object specified for the enlistment is a subordinate branch of the Transaction. Only the root of the Transaction can be enlisted on as a superior.
