In the boxes of the Record View Count dialog box, you enter values that determine which records are displayed in Data Prep Editor:
View count—The number of records to be displayed (up to 500). By default, Data prep Editor displays 50 records.
Start record—The number of the first record to be displayed. For example, if you enter 5, Data Prep Editor does not display records 1 through 4. By default, Data Prep Editor begins the display with record 1.
