On June 12, 2006 the AES generated a number of invalid response messages. As of June 13th, the issue has been resolved.

The following response messages were affected:

Response Code: 030 Fatal Error – Header USPPI ID Must Be Numeric
Response Code: 031 Fatal Error – Trailer USPPI ID Must Be Numeric
Response Code: 076 Compliance Alert – USPPI Can’t Be Changed Post Departure
Response Code: 227 Fatal Error – Forwarding Agent Party Missing

Several AES filers may have received these response messages in error or had problems receiving their Internal Transaction Number (ITN) for a number of shipments.
