Siva,
Although I normally do traditional EDIFACT, having a look at your error message seems to suggest that the Transaction Set Identifier is missing. Furthermore, the erorr message The X12 transaction set with id ” contained in functional group seems to suggest that the Transaction Set Identifier is in fact missing.
I’m presuming that a Transaction Set Identifier is similar to an EDI Interchange identifier – is it possible to supply this value and re-run the message?
Regards, Nick.
