Concurrent Request無法取消執行

當Cancel Request時，出現下列的錯誤訊息：
Request xxxxxx can no longer be cancelled. The Concurrent Manager Process that was running this request has exited abnormally. The ICM will mark this request as completed with error.

在網路上找到解決的方式如下：
Manually cancel the request out of the queue with the following SQL against the offending
request id(s). This can be safely done while managers are up and running

UPDATE fnd_concurrent_requests
        SET phase_code = 'C', status_code = 'X'
         WHERE request_id = 10975869;

回到EBS，可以發現它已經Cancel了
