You have started an export via Rechnungsdatenservice 1.0. The export of one or more documents fails with the error 'File is too large'.


One or more documents are larger than 20MB. DATEV only allows files up to a maximum of 20MB. But: we actually do too. So how could you upload something that is larger? 🤔 We'll take a look at it.


  1. You download the document in question and make it smaller. You can do this with Adobe Acrobat on Windows, for example, or Preview on a Mac. When you open a PDF file, you have the option to save it at a reduced size.

  2. Then you upload the file to Candis and send it to the share again.

  3. You delete the old file.

And we look at how the error could have happened in the first place.
