It would be nice, if the file name field in the Excel/File connection would be longer. Depending on the choosen location the path can be very long. So if the user wants to check over the path of the file or wants to replace certain parts with variables it´s more convenient to see the whole path (or atleast more of it). Compared to this the field size for the database name in the jedox olap connection is scalable and long enough.
As a workaround right now, I copy the path into the description field to see the whole path.
