Choose a distinct primary key that uniquely identifies and ties together these independent milestones to represent loan application. In this example, loanId is used as the primary key. Enter loanID in the Primary Key field in each milestone. You must use the same data type as the primary key for all milestones in any given business journey.

In addition to the default information collected by the Business Journey, such as event timestamp, you can extract additional business information, such as customer details, loan amount, loan type, bank name, and so on with the optional fields. These additional fields provide further context for your Business Journey definition. You can also use these fields to run ADQL queries.
