# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/data-integration-issues/troubleshooting-transformation-steps-and-job-entries/step-is-already-on-canvas-error.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
