Connector and Metadata wizard - Completing the Select Table Columns form (SQL)
Use this form to specify the table columns that hold the data that is pertinent to the application you are building. (The primary key column is always selected.)
For each column you select, the wizard generates a Pega Platform property and associates it with the external column. If you do not select a column, records that are retrieved from this table do not contain data from that column.
To create only the appropriate data model rules, without creating associated activities, check the Generate Data Model only box.
Select the appropriate columns, and then click Next.
