Hi Robert, apologies for replying in English but I don't know German. I don't think there is an easy solution, but here is one possibility:
1) Create a Calendar with German holidays.
2) The create an 'every day' schedule using the new calendar.
3) Modify the process by adding a decision to immediately stop if today is not the 9th working day.
This is not an ideal solution, and it will cause your process to run every day for a few seconds, apart from the 9th day where it will run as normal.
