Scenario: CashDisc form
You must extend the CashDisc form to add a new field named MinimumInvoiceAmount to the form. You must add a new Extended Data Type to the extension model for the new field. The new field must be added above the discount method field. The field must display 10 characters.
Box 1: extension
To add a new field to an existing table, you must first create a table extension.
Box 2: field
Box 3: field group
Box 4: data source
Often, the information that is stored in existing tables doesn't satisfy customer requirements. Therefore, additional tables must be created, and data from those tables must be shown on pages.
You can add new data sources to existing forms through extension. Follow these steps.
* In the extension model, create a form extension for the selected form.
* Right-click the form extension, and then select New Data Source.
