Thanks!
The problem is the missing quotes around N here:
`kz_aktiviert` CHAR(1) NOT NULL DEFAULT N ,
`kz_gesperrt` CHAR(1) NOT NULL DEFAULT N ,
To prevent this from happening, be sure to use single quotes to enclose the default value. So in the WB column editor, enter 'N' rather than N.
It might seem strange to make the user responsible for entering the quotes, but there is actually a good reason for that. If the quotes would not be entered, and WB would assume N in the field should be translated to 'N' for string type columns, then it would be impossible to distringuish between NULL and 'NULL'.
There maybe other ways to solve this, but for now, you should simply enclose your default value in single quotes.
