What does BR-24 mean?

Every invoice line must state its net amount. Without it, nobody can check the line total of the invoice.

Common causes of BR-24

The line has no invoice line net amount, the element ram:LineTotalAmount is missing entirely.
The invoicing software did not calculate the line total or wrote it into the wrong element.
The amount sits in GrossPriceProductTradePrice instead of the LineMonetarySummation.

How to fix BR-24

Find the faulty spot in the XML. Open the XML of the invoice and go to field BT-131 along this XPath://ram:IncludedSupplyChainTradeLineItem/ram:SpecifiedLineTradeSettlement/ram:SpecifiedTradeSettlementLineMonetarySummation/ram:LineTotalAmount
Apply the fix. Every invoice line (BG-25) needs an invoice line net amount (BT-131). Add the element ram:SpecifiedTradeSettlementLineMonetarySummation/ram:LineTotalAmount to the line. The value is quantity times item net price (BT-146), for example 3 units at 10.00 EUR gives 30.00.
Validate again. Save the file and validate it again to check that BR-24 is no longer reported.
