Use form dep.g to demonstrate Dynamic View Dependencies

The form dep.g has been prepared to demonstrate Dynamic View Dependencies. You can interact with this form to see the DVD examples this form uses and the dynamic effects they create.

To understand DVD examples on the dep.g form:

  1. Click Tailoring > Forms Designer.

  2. Type dep.g in the Form field, and click Search.

    The dep.g form opens.

  3. Select the Instructions tab for instructions on how to use three types of DVD conditional statements. For more information, see Dynamic View Dependencies.
  4. Follow the instructions and interact with the different fields to observe how the View properties change dynamically.
  5. Click Design.

  6. Inspect Properties View to see what values are assigned to create the effects. The following tables explain those properties that create the dynamic effects on different tabs of the form.
