Filterable fields are attempted to be autodetected by using the exportable fields. Records can be filtered by fields with type select,select-cat,select-account,date,date-time (according to egw_record class) only at this time. Filters are saved in the definition and used with scheduled exports. They are also available to the user for modification in the export dialog.
