In this example we want to mask credit card numbers in the CreditCard table, so first we place the CreditCard masking activity into opened Package.xaml and put the Generate credit card numbers masking activity within it. Once placed, we select the Number property. Lastly, we select the credit card number type that we want to generate. In this case we don't have a preference, so we choose Any credit card.
