# Generate category rules from a field

Generate category-rule suggestions from a product field, then review and save each mapping.

{% hint style="info" %}

#### When to use this method

Use **Generate from field** when a product field contains values that can help map products to channel categories. You review and complete each suggested rule before saving it.
{% endhint %}

{% hint style="warning" %}

#### Limit generated suggestions

Channable shows a maximum of 35 pages of generated categories. Use broader mappings when several detailed source categories map to the same channel category.
{% endhint %}

{% stepper %}
{% step %}

#### Open manual categorization

1. In Channable, open your channel.
2. Go to **Categories**.
3. Click **Manual categorization**.
   {% endstep %}

{% step %}

#### Select a field for rule suggestions

1. Click **Generate from field**.
2. In **Category field**, select a field with useful category context.
3. Click **Save**.

Channable creates partially completed category rules from the field values.
{% endstep %}

{% step %}

#### Complete the suggested rules

1. In each suggested rule, click **Set to category**.
2. Select the appropriate channel category from the suggested options.
3. Repeat this for the rules in the **Manual categorization** list.

The category options are listed by prediction confidence.
{% endstep %}

{% step %}

#### Save and review coverage

1. Click **Save** to run the category rules.
2. Review the categorized and uncategorized item counts.
3. Update or add rules until the mappings meet your needs.
   {% endstep %}
   {% endstepper %}

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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://helpcenter.channable.com/manage-improve-product-data/categorize-products/manual-categorization/generate-category-rules-from-field.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
