Add support for EDIFACT Syntax Version 'X' in UNB envelope

It appears that the latest EDIFACT standards ("VDA-EDIFACT" for automotive) allow for an 'X' to be used as the syntax version in the UNB envelope. Unfortunately, doing so fails both enveloping and de-enveloping in SB2Bi (as confirmed by IBM PMR TS019667069).

What is your industry? Automotive
How will this idea be used?

This is a roadblock for the implementation of certain documents for trading partners, and requires an unfavorable workaround.

    Hi Mark,

    the keyword replace is a workaround that I told IBM support about to avoid our partner from rejecting our invoices as of Febr 1st, as we know the fix won't be available by then after speaking to the IBM product manager (DM) about getting the proper fix and this should be considered a workaround only, not the permanent solution. The EDI enveloping should allow for value X and if that is selected then the UNB header date format needs to be in YYYYMMDD instead of YYMMDD.

    We were told that IBM is working on getting this implemented in the latest stable release (6.2.0.4) and expect that to happen.

    Is there any update on this?

    The VDA recommendations with version X exist since 2022 as you can see in the link below and our customer will start rejecting our invoices as of Febr 1st, so time is of the essence here.

    The switch to version X is a recommendation from the VDA, which the customer is implementing.

    Invoices to our customers will be rejected if we cannot adjust the UNB with the syntax version X. Currently we are just warned daily, but once they reject, this ha a massive impact on our day to day business.
