# Step tab

![](/files/CMgdaP295pQiYhF0GFbm)

You use this tab to specify step behavior.

| Option             | Description                                                                                                                                                                                                                                                                                                                                                        |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Result field name  | Enter a value to add a **String** field to the step's output stream containing output information for each command executed. If more than one command is specified for execution, there will be a row output with resulting information for each command.                                                                                                          |
| Command field name | Enter a value to add a **String** field to the step's output stream containing command information for each retrieved row. This field identifies the structure of each row’s results when there are multiple commands executed in the script and the subsequent step parses the information. Leave the field name empty to omit this field in the output stream, . |
| Stop on error      | Select this option to write to the log and stop the transformation when an error occurs. If if you do not select this option, errors are reported to the step's error-handling stream.                                                                                                                                                                             |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/10.2-data-integration/pdi-transformation-steps-reference-overview/mongodb-execute/options-mongodb-execute/step-tab.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.
