The Dateformat variable defines the default date format used by Date(), Date#() and other date returning functions. It does not control the date format of fields read from a data source. If the dates returned by the QvSAPBExConnector are valid numerical date types (they will right-align in list box), then convert them to the default format using Date(fieldname).
