Usage

To use the Generate items masking activity, it must be placed inside a table masking activity or a similar activity that iterates over data. Once placed, select the property you want to mask and create a new instance of the generator that uses values from the collection of items, that are going to be assigned to the selected property in the order as they are written.

Additionally, you can set the EnforceUnique property to make sure every assigned item is unique. This option must be used with care so that the number of table records is not greater than the possible items in the defined range.

Example

In this example we want to assign an item from the defined collection to the first 8 table records of the Address table. First, we place the Address masking activity into opened Package.xaml and put the Generate items masking activity within it. Then select the type of the items that are going to be used: Int32.

Figure 1: Select Type window

Once placed, we select the Number property that we want to mask with generated items. In Items field enter new int[]{1,2,3,4,5,6,7,8}.

Figure 2: Generating items

Modify Filter property to mask only first 8 table records: x=>x.AddressID<=8.
