      c.      Random Table for Time Periods

      d.     Value Range Table

      e.     Random selection table with multiple columns – (this scrambling type Random selection table with multiple columns(2,3,4,5,10,15,20,30)  is to used create global mapping )


5.  By choosing the push button “Export” you can save the mapping values entered in the column to the file in .CSV format (for example Scramblingvalues.CSV) in  your local system.

6.  Choose push button “Import”.






    7. Browse for the file and choose “Ok” button.

Note: If the scrambling values are already provided then choose “Overwrite values” check box and it overwrites the values with the values provided in the file.

The Exported file format contains (Table Name, Field Name, Primary table, Routine Name, Do not scramble, is a cluster table) as column names.

   2. By choosing the push button “Export” you can save the table-field values entered in the column.



   3.   Provide the values for table name, field name and give the value ‘X’ if the table field combination is a primary table field and provide the routine name in the file.

      When I create a new rule, scrambling types are empty. How can I load the default values?


      Best regards,
