Review the EDI Sequence Check Queue

The EDI Sequence Check Queue is used for X12 and EDIFACT sequence and duplicate checking. You can check the contents of the queue through the UI (Trading Partner > Document Envelopes > EDI Sequence Check Queue). Any interchanges that are in the queue will not be able to be processed after upgrade because the EDI compliance report serialized format has changed.

The EDI Post Processor displays the following error:

The compliance report for interchange <interchange document ID> could not be 
deserialized because the format has changed. The entry for this interchange 
should be manually removed from the EDI Sequence Check Queue through the UI, 
and the inbound deenvelope workflow should be rerun (WF ID <wfid>).

If you receive this error, follow the instructions in the error message to correct the situation.
