Details on Common Errors
KB001_01 – Problem Signing Receipts
This error is often related to short-term outages or maintenance work at Fiskaly.
In such cases, the following can occur:
- individual receipts may temporarily not be fully signed
- DATEV exports may not be processed correctly
- warnings or error messages may appear during the DATEV export
- syncing between Shore and DATEV may fail
Important:
Creating receipts and daily closing reports in the POS system is generally not affected by this.
In most cases, the message only concerns the further processing of the exported data at DATEV.
This is often a temporary external outage that resolves itself automatically after a short time.
Recommendation:
- Check the Fiskaly status page
- Retry the DATEV export later
- Forward the affected daily closing report to your tax advisor
- If the issue persists for a longer time, contact Shore Support
KB001_02 – VAT ID Format Error
This error occurs when a company invoice includes a VAT ID that doesn't match the format expected by DATEV.
DATEV Expects:
- exactly two uppercase letters at the start (e.g. DE, AT, FR)
- followed by 1 to 13 alphanumeric characters
- no additional spaces or special characters
Examples of Valid Formats
- DE123456789
- ATU12345678
- FR12345678901
Common Causes
- typos in the VAT ID
- extra spaces
- incorrect country code
- invalid special characters
- incomplete VAT ID
Important:
An incorrect VAT ID can block the entire DATEV import.
Even a single faulty transaction can cause a complete DATEV export to be rejected.
Recommendation:
- Check the VAT ID before issuing the invoice
- Only enter a VAT ID if you're sure it's correct
- If no valid VAT ID is available, leave the field empty
- Run the DATEV export again after making the correction
General Troubleshooting Tips
Many DATEV errors can be avoided by regularly checking your master data.
We recommend:
- Checking VAT IDs before issuing invoices
- Regularly reviewing DATEV exports
- Saving error messages along with a screenshot
- Re-running DATEV exports after Fiskaly outages
- Contacting Shore Support for recurring issues
New Year Not Opened
If the new fiscal year wasn't opened in time in DATEV, the corresponding entries can't be transmitted automatically. In this case, you'll need to enter them manually in DATEV as a one-time correction.
Please make sure to open the cash book for the year in DATEV by January 2 at the latest. Unfortunately, we're unable to transmit this retroactively on your behalf in that case.
Here's how to proceed:
- Log in to your account at manager.shore.com.
- Go to Reports → Download → January XXXX XLS Reports.
Tip: An even faster way is via Reports → Cash Book → Select Date → January XXXX
MeinFiskal Transmission Isn't Working
If transmission via DATEV MeinFiskal isn't working, this may be because no suitable storage folder yet exists for filing your accounting documents in DATEV Belege online. In this case, you can create a new storage folder if needed.

- Correctly saved account number and a current cash balance
