Adding Steps or Job Entries

Adding steps to a transformation (or a job entry to a job) on the canvas is easy: simply select a step type from the tree on the left and drag in onto the canvas:

At the location of the mouse you will see a square that represents the location of the steps when you let go of the button. When you let go of the mouse button the selected step (Text file input) will become part of the transformation.

You can also add a transformation step by right-clicking on the workspace and selecting New Step, then Step type.
