You can broaden identification criteria by enabling multiple identifiers of the same type for a single entity. For example, one person may have two passports and use each passport as a means of identification.

1. In the Dev Studio Explorer panel, click App. In the search field, enter PegaPS-Data-Entity-Person.

2. Initialize the IdentifiersList property by performing the following steps:

   1. Click Data ModelData TransformpySetFieldDefaults.

   2. In the Definition tab, click Add a row.

   3. In the Action column, select Comment. In the Target column, enter a description for the set of steps, for example, IdentifiersList initialization.

   4. In another row, in the Action column, select Update Page. In the Target column, enter .IdentifiersList.

   5. In the substep, apply the CreatePage data transform rule. Ensure that the class name that the data transform rule references matches the class of the identifier that you modify, for example, PegaPS-Data-Identifier-Passport.

   6. Add a second substep and set the .IDType property as equal to the identifier that you modify, for example, "Passport".

3. In the Application Explorer, click User InterfaceSectionVerification.

4. From the Layout drop-down list, drag the Embedded section option into the Verification details section.

5. In the Section Include window, perform the following actions:

   1. From the Page context drop-down list, select Use clipboard page.

   2. In the Class field, type PegaPS-Data-Identifier.

   3. In the Clipboard page field, type .IdentifiersList(1).

   4. From the first Section drop-down list, select By name. From the second list, select IDNumber.

6. In the Application Explorer, click TechnicalActivityPersistEmbeddedPage.

7. On the Steps tab, in the step that calls the .IdentifiersList page, remove the // label.
