DATEV Rechnungswesen

For tenants using DATEV Rechnungswesen (desktop / on-premise stack), Cortena exports Buchungsstapel files in EXTF format, including SKR chart mapping, creditor creation, and correction (storno) flows.

1. DATEV RW vs DATEV DUo

Confirm with your advisor which product you use before configuring Settings.

2. SKR chart and export file

1. Connect credentials in Settings → Integrations → DATEV Rechnungswesen.
2. Set SKR03 or SKR04 (and related options) to match your DATEV mandate.
3. Align accounts and tax keys, then run a pilot export and validate in DATEV.

Export from Payables produces an EXTF batch file your advisor imports into RW. Preview in Cortena shows accounts and amounts before download.

The Buchungsstapel is assigned in DATEV to the posting month of the export (not the calendar year-end). Invoice document dates on the booking lines stay the invoice date.

3. Creditor creation in REWE

When a supplier does not exist in DATEV, Cortena can include new creditor (Kreditor) records in the export package so REWE creates them on import, subject to your workflow and tenant policy.

Verify creditor numbers in export preview match your Stammdaten expectations.

4. Corrections and storno

Wrong export to RW? When Cancel booking after sync is enabled on the export workflow step, Synced is soft-final:

1. Open the synced invoice → workflow strip → Cancel booking (Generalumkehr storno).
2. After storno succeeds, the invoice returns to Ready to sync / Export to accounting. Edit booking as needed.
3. Send correction (Korrektur-prefixed Buchungsstapel). The workflow marks Synced again.

Your advisor should import storno before the replacement batch. Activity log records both exports.

5. Delivery date (Leistungsdatum)

When feature DATEV RW EXTF Leistungsdatum is on, payable detail shows Delivery date (DE: Leistungsdatum). Edit it on the invoice or set it with the workflow step Set invoice date. The stored value is what EXTF export can include. Keep it aligned before you download the Buchungsstapel.

6. RDS and permissions

DATEV RDS (cloud middleware) requires correct permissions on the DATEV side. If import fails with RDS errors, contact support with the error text and Mandant details.
