Creating a Default Input Value

After you add an Input component to the mapping area, notice the default item to the left of the component.

map_simple_input

Simple input component

The default item enables you to connect an optional default value to this input component, as follows:

 

1.Add a constant component (on the Insert menu, click Constant), and then connect it to the default item of the input component.

cmd-inp6

2.Double click the input component and make sure that the Input is required check box is disabled. When you create a default input value, this setting is not meaningful and causes mapping validation warnings.

3.Click OK.

 

Note:If you click the Specify value check box and enter a value in the adjacent box, the entered value takes precedence over the default value when you preview the mapping (that is, at design-time execution). However, the same value has no effect in the generated code.
