GTC - extension of failure message

Previously, the Failure Reason Code in the Document Check Results (tcgtc1610m000) session was only used to determine the cause of a GTC failure, but it was not always informative.

Now, the failure message in the Document Check Results (tcgtc1610m000) session and similar sessions has been extended to record more details about the cause of the GTC failure. For example, the failure message now contains details of quantities or amounts that have been exceeded.
