Troubleshooting Common Validation Problems

Resolve numbering, permission, period, quantity, stock, credit, payment, import, and integration errors safely.

Read the complete validation message, keep the record in Draft, and correct the source condition. Repeated submission without a change can create confusion and will not bypass server rules.

Problem	Check
No document number	Active series, correct type, fiscal year, counter, and manual-code confirmation.
Access denied	Member role, module permission, and separate action/override permission.
Locked period	Document date, fiscal-year status, approved correction method, and override reason.
Insufficient or negative stock	Selected warehouse, on-hand/reserved/available quantities, source movements, and override policy.
Quantity exceeds source	Remaining delivered/received/billed/returned quantity and configured tolerance.
Credit limit exceeded	Customer balance, limit, payments/credits, and authorized override.
Payment cannot allocate	Direction, partner, currency, outstanding amount, payment total, and reversal state.
Import rejected	File type, headers, date/decimal format, codes, duplicates, and required references.
eFaktura blocked	Environment, identity, reference catalog, signer, mappings, validation, and UJP response.

Do not work around validation by changing a date, warehouse, partner, item type, or reference to something untrue. If the correct source still fails, save the exact time, company, route, document code, action, and message; remove secrets and contact support.
