What it means
The rule checks every discount or charge on a line (cac:AllowanceCharge), on an invoice line or a credit note line, for an identifier (cbc:ID). It has no identifier. The test only checks that the element is there.
Why it matters
This is a warning. It is worth fixing to keep the file clean and to remove the warning.
How to fix it
Delete cbc:ID from the discount or charge on the line. Make sure it still has an amount and a reason, given as text or as a code. For a discount the reason is BT-139 or BT-140, for a charge BT-144 or BT-145.
