How to fix BR-26
Each Invoice line (BG-25) shall contain the Item net price (BT-146).
What this rule checks
The item net price (BT-146, mapped to cac:Price/cbc:PriceAmount) is the unit price of the item after any item-level price discounts but before VAT. This value is required so the receiver can verify the line extension amount by multiplying quantity by price. It must use the same currency as the document currency.

Common causes
- The
cac:Price/cbc:PriceAmountelement is missing from the invoice line. - The
cac:Priceblock is entirely absent. - The price amount element is empty or contains non-numeric text.
- The currencyID attribute on PriceAmount does not match the document currency.
