What it means
This rule counts supporting documents (BG-24) whose description (BT-123) is LISIBLE and permits a count of zero or one. In UBL, it checks cac:AdditionalDocumentReference entries with cbc:DocumentDescription set to LISIBLE. The CII variant uses BG-24 and BT-123 for the corresponding fields. This rule does not require a LISIBLE document.
Why it matters
LISIBLE identifies the readable copy of the invoice. Limiting that label to one supporting document avoids having several documents marked as that copy.
How to fix it
Find every supporting document whose description is LISIBLE. Keep the label on the intended readable copy. Remove a duplicate document reference, or give another document its appropriate permitted description code. You may leave a description unset if no other requirement needs it. Export the corrected file and recheck it.
