To create an interface field

Note:
  • Interface fields created in this manner are automatically mapped to the originating field.
  • The Direction property for an interface field is automatically set based on the direction of the originating field as follows:
    Direction of the originating field Direction of the interface field
    Input Input
    Input/Output Input
    Output Output
  • You can also create an interface field by one of the following methods:
    • Right-click the originating field and select New Interface Field... from the popup menu.
    • Right-click in the Interface Fields pane and select New Interface Field from the popup menu. In this case, a default mapping is not generated for the new interface field. Therefore, be sure to map the new field manually.
