Usage

To use the Generate value masking activity, it must be placed inside a table masking activity or a similar activity that iterates over data. Once placed, a Select Types window will open where you must choose the TValue type, i.e. the type you want to generate. Selecting the Browse for Types... option will open the Browse and Select a .Net Type window where you can search for more types. After clicking OK, you can choose the property you want to mask. Next, enter a new instance of a generator to generate values.

Example

In this example we want to generate street numbers in a sequence for the Address table. First we place the Address masking activity into opened Package.xaml and put the Generate value masking activity within it. In the Select Types windows we choose Int32 as the TValue. Once placed, we select the Number property that we want to mask with our text generator. For the generator, we enter a new instance of a string generator that also makes use of a number sequence generator so that our generated e-mails are unique.
