We happen to notice that the June 2014 ERRATA do not contain a 1.2 Version information change while the .Type 1 ERRATA do contain them. Does this mean the version in GS08 and ST03 would change only on the transactions that have Type 1 ERRATA and would not change for the transactions with ERRATA updates?
That is correct. Type 1 Errata also known as Addenda, by definition contain significant changes that change the transmitted transaction set defined by the Implementation Guide. Both the sender and receiver must implement the Addenda to conduct a successful interchange. Therefore, the Addenda version (005010X220A1) in the case of the June 2010 Addenda must be reported in the GS08 and ST03.
Type 2 Errata by definition are minor changes that clarify or correct the Implementation Guide but do not change the transmitted transaction set defined by the Implementation Guide. The sender and receiver do not both have to use the Type 2 Errata to conduct a successful interchange. Therefore, the Errata version (005010X220E2) in the case of the June 2014 Errata is not reported in the GS08 and ST03.
