Specifying scrambling options
Scrambling data allows you to create test data based on production (or "live") data, but with the ability to change the values of certain fields.
When you use the Copy Utility (option 3.3) to copy data from one data set to another data set, you specify the fields you want scrambled by marking those fields for scrambling in the output template.
You mark a field for scrambling by setting the scrambling options for that field in the template.
You can specify or change scrambling options on the Field Attributes panel. The panel comes in two flavors: one for alphanumeric fields and the other for numeric fields.
