The next step is to store newly created record locally for an offline application or send the new record directly back to the backed for online applications.

6. Click Next.

7. In Property and Create Links step, uncheck City.

   Since in Customer_Create.page, we defined five properties (First Name, Last Name, Phone, Email & date of birth) to be added, now in this step, we will bind them to respective UI Controls.

   Check the DateOfBirth property and click the link icon to open the object browser.

   When Customers_CreateEntity.action gets executed successfully then CloseModalPage_Complete.action will be triggered or if Customers_CreateEntity.action fails then CreateCustomerEntityFailureMessage.action will be triggered.

   

10. Save the changes to the Customers_CreateEntity.action.

    Next, you will set the OnPress of the Save button.

    Now that the Create action is created, you will need to call the Create action when the end-user presses the Save button. You will add a Save button on the Customers_Create.page and link it to the Customers_CreateEntity.action.

    Double click on the Save type and click OK.

    

    In the Properties pane | Events tab, click the link icon for the OnPress property to open the object browser, bind it to Customers_CreateEntity.action.

    

12. Save the changes to the Customers_Create.page.
