What it means
The test checks for ram:ContentCode inside ram:AssociatedDocumentLineDocument/ram:IncludedNote on an invoice line. Its presence triggers the warning, even if it is empty. Despite the official message mentioning Subject, this test does not check ram:Subject.
Why it matters
EN 16931 represents the line note through its text (BT-127), rather than this separate content code. A warning does not establish whether the recipient will accept your invoice.
How to fix it
Remove ram:ContentCode from the affected line's ram:IncludedNote. If its meaning matters to the buyer, write that meaning in ram:Content instead. Export the revised CII file and check it again.
