# How to Modify the Schema

### 1. Navigate to the Data Sources page

### 2. Select the data source

### 3. Scroll down to the Schema Transformation section

Schema transformations are used to modify the source schema during the materialization process.

### 4. Click the + symbol in the bottom row to add a new schema transformation

To delete a row move your mouse to the leftmost column in the table to reveal a checkbox, check the box, and press the delete key.

### 5. Add the required schema transformation properties

For this guide we will add four transforms. See the table below the screenshots for exact values

### 6. Save the Schema Transformations

### 7. Ensure the transformations/consolidations updated successfully

# 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.datapancake.com/guides/how-to-guides-ui/creating-and-configuring-data-sources/how-to-modify-the-schema.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.
