Reference
BR-CO-10 Sum of invoice line net amount must equal the total of all line nets
The document-level Sum of invoice line net amounts (BT-106) must equal the arithmetic sum of every Invoice line net amount (BT-131).
Problem Description
The document-level Sum of invoice line net amounts (BT-106) must equal the arithmetic sum of every Invoice line net amount (BT-131).
ERROR
XRechnung 3.0
Context and Significance
Mismatched line-sum totals are one of the most frequent rejection causes when an ERP exports to XML without rounding alignment. Public-sector portals refuse the file before any human review.
Solution
Recalculate BT-106 from the actual line nets and write the recomputed value back into the invoice header.
Valid Examples
- Lines 100.00 + 50.00 + 25.00 yield BT-106 = 175.00
- Single line of 99.99 yields BT-106 = 99.99
Invalid Examples
- Lines sum to 175.00 but BT-106 = 174.99 (rounding drift)
- BT-106 left at 0.00 while lines exist
