The expense submission business process requires a few data elements. In Emakin these are defined by a data model. Although the user has full control of the data model, the Process Designer assists the user by transparently updating the data model whenever changes are made to the form.

The Process Designer automatically creates one default data model, named Data, and that’s good enough for this exercise. We’ve already designed the form, so it's expected the data model to have been updated accordingly. Let’s review the data model and verify that its hierarchical structure is similar to the one depicted below.

- Data
  - ExpenseReport
    - Origin
      - Employee
      - Department
      - Date
    - Details
      - Expenses
        - Expense
          - Description
          - Amount
          - Currency

1. Click the Expense Management folder entry on Emakin’s sidebar and the folder is displayed;
