InvoiceIn checks · validation rule

InvoiceIn checksWarning

The line total does not match its own price and quantity. EN 16931 defines this calculation (BT-131 = BT-146 x BT-129 / BT-149, less line allowances, plus line charges) but ships no rule for it, so the document can be formally valid and still be wrong by this amount. Check the line before paying it; the sender must correct either the price, the quantity or the line total.

This is a property of the file you received, so it cannot be corrected on your side without changing the document — ask the supplier to reissue it.
