# Step is already on canvas error

If a step is hidden on the canvas in the PDI client, you may receive a "Step is Already on Canvas" error message when trying to work with its transformation.

Regardless of whether a step is hidden or displayed in the canvas, it is listed in the **Steps** folder under your transformation in the **View** tab of the Data Integration perspective. To redisplay the hidden step on the canvas, drag it from the **Steps** folder in the **View** tab to the canvas.
