BR-FR-06_BT-21-4: Use the tax marker #TXD# at most once

In short

Fatal: fails the selected checks.

BR-FR-06_BT-21-4 means #TXD# occurs more than once in the combined notes of your UBL invoice or credit note. Keep the relevant tax statement wording in a document-level cbc:Note and leave only one #TXD# marker across all the notes.

What it means

The test counts occurrences of the exact text #TXD# across the combined document-level notes (BG-3 in this rule). The marker represents subject code TXD (BT-21) within note text (BT-22). Zero or one occurrence passes this test; two occurrences fail even if they are within one note. This rule does not require the marker to be present.

Why it matters

The TXD marker identifies your tax statement, and this format limits it to one occurrence in the combined notes.

How to fix it

Find every #TXD# in the document-level cbc:Note elements of your invoice or credit note. Remove extra occurrences within a note. If several notes contain the marker, combine the relevant tax statement wording with one #TXD# and remove duplicate content without losing text you still need. Generate the file again and recheck it.
