Scope & Requirements
You use a DATEV integration in Candis.
The DATEV access method determines the available export types: RDS (Rechnungsdatenservice 1.0) or BDS (Buchungsdatenservice).
If no active connection exists, you export via file exports in DATEV format.
Note: Candis only displays export options that match the current DATEV connection status.
Export Logic at a Glance
DATEV-Specific Export Types
Candis uses export formats that comply with DATEV requirements (e.g. DATEV format CSV, DATEV format XML).
Status-Dependent Options
Not connected: File exports (CSV, XML).
RDS connected: Direct connection via Rechnungsdatenservice 1.0; file exports remain optionally available.
BDS connected: Direct connection via Buchungsdatenservice; file exports remain optionally available.
Validation of Account Numbers (DATEV-Compliant)
Account numbers must follow strict rules to ensure error-free exports to DATEV:
Numeric only: Account numbers may contain digits only.
Number ranges: Fixed number ranges apply to debtors (customers) and creditors (suppliers).
First digit rule:
1–6: Debtor accounts
7–9: Creditor accounts
Examples
Debtor 10001 ✔︎ | Creditor 800001 ✔︎ | A12345 ✘ (not numeric) | 65000 as creditor ✘ (incorrect number range)
Available Exports
File Exports
DATEV format CSV: Standardized CSV file for import into DATEV systems.
DATEV format XML: Structured XML file based on DATEV specifications.
Use file exports if:
no direct DATEV access method exists,
you want to review, archive, or manually import files into DATEV.
Direct Connections
Belegbilderservice: Transfers PDF documents to DATEV Unternehmen online.
Use this option if you want to provide document images and create postings separately.Rechnungsdatenservice 1.0 (RDS): Transfers invoice data (structured data) including the document image.
Use this option if you want to transfer complete invoices (data + PDF) to DATEV.Buchungsdatenservice (BDS): Transfers posting records in DATEV format.
Use this option if you pre-post in Candis and transfer posting batches to DATEV.
Common Pitfalls & Notes
Inconsistent master data: Different debtor or creditor numbers between Candis and DATEV cause assignment errors during import.
