All your settled transactions made from a EUR wallet in the last 90 days can be exported and you can choose which transactions to export.
This includes transactions made on cards as well as transactions related to main wallets (such as billing, fees, and transfers from/to other bank accounts). Attachments, if present, will also be exported.
The only exception is internal transfers (moving money between wallets of the same currency). These transactions won’t sync with DATEV.
