Is there any connector for DATEV? And if not, is it possible to create a new one?
Thanks in advance.
There is no branded connector.
However, it should be fairly easy to convert data into their format for import. My exposure to DATEV is extremely limited, so I don't remember what options they provide for automated imports, but their data format is not overly complex. As far as exporting data, I seem to remember it (or at least the version at the time) running on SQL Server, so you should be able to connect with the standard DB connector to pull data that way.
In terms of building a new connector, I'm sure it could be done. It's just dependent on what their SDK is like, and the interfaces they enable.
