Parameters are local variables that apply only to a specific transformation where you define it. When defining a parameter, you can assign it a default value to use in the event that one is not fetched for it. This feature makes it unique among dynamic input types in PDI.
Note: If there is a name collision between a
parameter and a variable, the parameter will take precedence.
To define a parameter, right-click on the transformation workspace and select Transformation settings from the context menu (or just press Ctrl T ), then click on the Parameters tab.
