Invoice line net amount does not reconcile
What it means
The line net amount (BT-131) must equal quantity × (net price ÷ price base quantity), plus line charges, minus line allowances. A mismatch is nearly always a rounding difference or a price base quantity that was ignored when the line was calculated — the individual values are right but the product was computed differently.
Can it be fixed automatically?
Nothing about your business is needed to fix this — the correct value is a constant, a code list entry, or is already present in the document.
This one can be repaired automatically. The API applies the fix, re-validates, and reports exactly what changed with before and after values.
How to fix it
Recompute the line net amount from the quantity, net price, price base quantity and any line-level allowances or charges already present on the line. Every operand is in the document, so no business input is needed.
