Balance not zero — debits and credits differ
Inbound invoice processing fails because the calculated debit and credit totals do not balance.
Quick answer
- Most likely cause
- The inbound invoice amount does not equal the sum of item, tax, and charge lines.
- Check first
- Invoice header amount versus item totals.
- First resolution step
- Reconcile header, item, tax, and charge totals outside the posting first.
Likely root causes
- The inbound invoice amount does not equal the sum of item, tax, and charge lines.
- Currency conversion or rounding creates a residual difference.
- A tax code, freight, or unplanned delivery-cost line is missing or mapped incorrectly.
What to inspect
- Invoice header amount versus item totals.
- Tax and delivery-cost segments in the inbound message.
- Currency, exchange rate, and rounding behavior.
- WE02/WE05 status records and application log for the invoice.
Resolution path
- Reconcile header, item, tax, and charge totals outside the posting first.
- Correct missing or duplicated mapped amounts.
- Align currency/rounding logic between sender and SAP.
- Reprocess only when the inbound document balances exactly according to the configured tolerances.
