Hi All
Has anyone been able to generate GS1-128 barcodes that are verified as GS1 compatible? I can generate a barcode using IDAutomation fonts but there's no way to include FNC1 characters as below post
 
Without this barcode doesnt pass the test see post here

    Hello,
    Yes — to generate a GS1-128 barcode that passes GS1 validation, you must include the FNC1 character at the beginning of the data string, because GS1-128 is simply Code 128 with FNC1 as the first character; without it, the barcode will fail verification. If you use variable-length Application Identifiers (like AI 10) and another element follows, you must also insert a Group Separator (ASCII 29) between elements. The limitation isn’t Business Central itself — it’s that barcode fonts (like IDAutomation) don’t automatically handle GS1 formatting rules, so you must pre-build the encoded string correctly (FNC1 + AIs + optional separators) before applying the font or use the BC Barcode module to control the encoding logic. Fonts alone won’t make it GS1 compliant.
