Message Text Edifact interchange should have contained UNA or UNB as the first segment. Instead {0} was found

Explanation

This Error/Warning/Information event indicates that the EDI receive pipeline could not process the incoming EDIFACT interchange because the first segment was neither a UNA nor a UNB segment. The UNA segment is optional; the UNB segment is mandatory.

User Action

To resolve this error, ensure that the sender of the interchange includes the UNA or UNB segment as the first segment of the interchange, and then resends the interchange.
