Stage 2 · What it checks
EN 16931 rules
- The core business terms are present (BR-01 to BR-65).
- Totals add up and related fields agree (BR-CO); codes and decimals are valid (BR-CL, BR-DEC).
- Each VAT category is consistent: S, Z, E, AE, K, G, O, L, M (BR-S, BR-Z, BR-AE, BR-IC …).
Example codes
Typical fix
Recalculate totals and VAT from the line data, and correct the VAT category in the source data.
Context and Significance
The validator checks this equation exactly, without tolerance. Failures usually come from prepayments or rounding: the ERP deducts an advance payment from the amount due but does not export it as BT-113, or it rounds the amount due without stating the difference in BT-114.
Solution
Recompute BT-115 = BT-112 − BT-113 + BT-114, treating BT-113 and BT-114 as zero when absent. UBL: cbc:PayableAmount, cbc:PrepaidAmount, cbc:PayableRoundingAmount; CII: ram:DuePayableAmount, ram:TotalPrepaidAmount, ram:RoundingAmount.
Quick actions
Valid Examples
- BT-112 = 119.00, BT-113 = 50.00, BT-114 = 0.00 → BT-115 = 69.00
- BT-112 = 99.98, BT-113 absent, BT-114 = 0.02 → BT-115 = 100.00
Invalid Examples
- BT-115 = BT-112 even though BT-113 = 50.00 prepaid
- BT-115 ignores BT-114 rounding adjustment of 0.02
