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.
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.
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 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.
If Power BI isn’t configured yet, share Configure Power BI for Langdock with your Power BI or Langdock workspace admin. If a question fails, see Troubleshooting.

​
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. 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.

​
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.
