What it means
The rule checks every discount or charge on a line (cac:AllowanceCharge) for a sequence number, a figure that puts several discounts and charges on the same line in an order. The rule fires as soon as the element is present.
Why it matters
This is a warning.
How to fix it
Delete cbc:SequenceNumeric from the discount or charge. Check that every discount and charge on the line carries its final amount, so the line adds up without any order.
