Typically, the data on this tab is from one of these two tools, and no manual changes are required.

Exposing an embedded Single Value property value into a column

For a concrete internal class, you can use this tab to expose match an embedded Single Value property in a database column.

For example, the embedded property .pyPreferences.pyNavigationPrefs.pyShowTabs manages whether a user wants to use tabs in his or her developer environment.

If it were important to use this embedded property as report selection criteria, the property must correspond to a column. Use these steps to make a (scalar) embedded property available as a database column.

1. Ask a database administrator to create a new column of the appropriate data type in the PegaRULES database table that corresponds to the Data-Admin-Operator-ID table. In this example, the table is pr_operators. The database administrator created a text column named TABDISPLAY. (You cannot use the Modify Schema wizard to add this column, because there is no property named TABDISPLAY.)
2. Update the Class rule for the class Data-Admin-Operator-ID. Add a row to the Column Mapping array on this tab. Enter the new column name TABDISPLAY the Column Name field and the embedded property reference in the Property Name field.
3. Thereafter, the system updates the new column TABDISPLAY from the embedded property .pyPreferences.pyNavigationPrefs.pyShowTabs.pyTabs whenever an Operator ID data instance is saved. The property reference .pyPreferences.pyNavigationPrefs.pyShowTabs.pyTabs can be used as criteria in reports.

This feature provides a direct but limited alternative to creating an Index- class and maintaining the index through a Declare Index rule, or to replicating the value to a second (top-level) property using a Declare Expression rule or Declare Trigger rule.
