Note

Semantic Modeling is a pilot or beta service that is subject to the Beta Services Terms at [Agreements - Salesforce.com](https://www.salesforce.com/company/legal/agreements/) or a written Unified Pilot Agreement if executed by Customer, and applicable terms in the [Product Terms Directory](https://ptd.salesforce.com/). Use of this pilot or beta service is at the Customer’s sole discretion.

1. Open your existing semantic model in the Semantic Builder.
2. Click on the Agentforce icon on the top right corner. The Semantic Modeling side panel opens.
3. Select the deployed Semantic Modeling agent from your active assistant list.
4. Ask the agent to modify or update your model by describing a structural change or field addition in plain text. Here are some examples:
    - Add a calculated field by asking "Add a calculated field for average sales per product family".
    - Change a calculated field by asking "Remove the quarter value from the sum in the average revenue per store calculated field".
    - Add data objects to the model by asking "Include case and contact objects to track our custom customer service performance metrics."
5. Semantic Modeling shows its suggestion for applying your request to the semantic model. When asking to change the data objects in the semantic model, you can click **Review** to open the list of available data objects. You can change the selections if needed by checking or unchecking items. When you’re ready, click Continue to return to your conversation with Semantic Modeling.
6. Click **Continue** to accept the suggestion and apply the change, or Ignore to cancel your request.
7. Semantic Modeling notifies you when the changes are applied. You can continue the conversation or leave it at that.
