FATAL
Official rule text
Sum of allowances on document level (BT-107) = Σ Document level allowance amount (BT-92).
What this error means
This is a consistency rule: two or more amounts in the invoice must add up exactly, and in your file they don't. The validator recomputes the total from its parts and compares it with the value you declared.
How to fix it
- Recompute the amounts referenced in the rule text above and make them agree.
- Round each line and each total to 2 decimals using the same rounding mode everywhere (banker's rounding is a common source of 1-cent mismatches).
- Never re-derive a declared total from scratch on the receiving side of your pipeline - compute it once, at the source, and carry it through.
