DATEV-EXTF validation

Before a DATEV-EXTF batch leaves the system, it passes a validation. If it fails, the export is blocked (EXPORT_BLOCKED) — an incomplete or inconsistent batch never reaches the tax advisor.

What is checked

The gate checks exactly the following conditions — it blocks as soon as one of them is not met:

• Open exceptions — there must be no open exception left.
• Amounts — no booking may have an empty (NULL) amount.
• Period closed — the export requires a closed period.
• Four-eyes principle — the period close follows the four-eyes principle (creator ≠ closer).
• Match coverage — the period-close wizard requires a match coverage of ≥ 95%.

The EXPORT_BLOCKED gate

As long as one of these conditions is not met, the export stays at EXPORT_BLOCKED. The system shows exactly what is missing — for example how many exceptions are still open or that the period is not closed yet.

EXPORT_BLOCKED: 3 open exceptions · period not closed yet

How to clear the block

1. Resolve exceptions — under Resolve (/exceptions), handle every open exception.
2. Check the chart of accounts — set the chart of accounts on the client (see Client settings).
3. Close the period — under Close (/periods) with the four-eyes principle.
4. Re-validate — the export runs through the checks again automatically; once green, you can build the 6-file handoff.

Why this is good

The gate prevents a faulty batch from reaching the tax advisor and needing manual rework there. Better to block cleanly once than book twice.
