# Microsoft Power BI

> Connect Power BI to Langdock to ask questions about reports, dashboards, and semantic models. Works on Power BI Pro, no Fabric capacity required.

## Overview

Use the Power BI integration to ask questions about business data in Langdock. Langdock finds the workspaces, reports, and semantic models you can access, looks up how a model is structured, and runs focused DAX queries. Every request runs as you, so you only see data your Microsoft account can already access, and row-level security still applies if the model uses it.

> [!TIP]
>
> You don't need Microsoft Fabric. Querying semantic models works on Power BI Pro workspaces and returns the same results as on Fabric capacity. Capacity only matters for report export and a few actions that need the XMLA endpoint. See [What needs XMLA](https://docs.langdock.com/en/admin/manage-integrations/integration-setup-guides/microsoft-powerbi/permissions-and-scale.md#what-needs-xmla).

Semantic models always use this integration, whether the workspace is on Pro or on Fabric capacity. Lakehouses, warehouses, and SQL databases in Fabric use the [Microsoft Fabric](https://docs.langdock.com/en/admin/manage-integrations/integration-setup-guides/microsoft-fabric.md) integration.

## Use Power BI

1. Open Power BI in Langdock, select **Add connection**, and sign in with your Microsoft account.
2. Tag **Power BI** in a chat.
3. Ask a question about your data. Name the workspace, report, or semantic model only when Langdock asks you to choose between multiple matches.

> [!NOTE]
>
> If Power BI isn't configured yet, share [Configure Power BI for Langdock](https://docs.langdock.com/en/admin/manage-integrations/integration-setup-guides/microsoft-powerbi/setup.md) with your Power BI or Langdock workspace admin. If a question fails, see [Troubleshooting](https://docs.langdock.com/en/admin/manage-integrations/integration-setup-guides/microsoft-powerbi/troubleshooting.md).

## Supported data

Langdock works with these items in Power BI workspaces you can access:

* Semantic models
* Reports
* Dashboards

To get numbers from a semantic model, you need **Build** permission on it in addition to workspace access. Your admin grants this once. See [Permissions and scale](https://docs.langdock.com/en/admin/manage-integrations/integration-setup-guides/microsoft-powerbi/permissions-and-scale.md).

Semantic models that are live connections to Azure Analysis Services or SQL Server Analysis Services can't be queried through Langdock. See [Live connections to Analysis Services](https://docs.langdock.com/en/admin/manage-integrations/integration-setup-guides/microsoft-powerbi/permissions-and-scale.md#live-connections-to-analysis-services).

## Large results

Microsoft limits how much data a single query can return and how many queries each user can send per minute. Conversational questions rarely reach these limits. Langdock returns large results as a CSV file instead of showing every row in the chat.
