Introduction
In the modern business world, data analytics plays a pivotal role in decision-making and strategy formulation. Power BI is one of the most widely used business intelligence (BI) tools that helps organizations transform raw data into meaningful insights through interactive dashboards and reports. One of the key features of Power BI is its ability to connect to various data sources, both cloud-based and on-premises.
Microsoft Dataverse (formerly known as the Common Data Service, or CDS) is a data platform that provides a unified and scalable data model. It enables organizations to securely store and manage data used by business applications, particularly within the Microsoft ecosystem (e.g., Dynamics 365, Power Apps, Power Automate). Dataverse plays a crucial role in enabling a single source of truth for organizations’ data, enhancing consistency and collaboration.
One powerful feature that Power BI offers is DirectQuery, which allows users to work with data in real time without loading it into Power BI’s in-memory engine. When used with Dataverse, DirectQuery enables users to query data directly from Dataverse, providing up-to-date insights without duplicating data.
In this article, we will explore how Power BI DirectQuery with Dataverse works, its benefits, potential challenges, and best practices for leveraging this integration.
What is DirectQuery in Power BI?
DirectQuery is a data connectivity mode in Power BI that enables users to query large datasets directly from a data source without loading the data into Power BI’s internal memory. Unlike Import mode, where data is loaded into Power BI and stored in its memory (which can improve performance but may require a large amount of memory for big datasets), DirectQuery leaves the data in the original data source. Instead of storing data within Power BI, DirectQuery sends the queries directly to the source system every time the report or dashboard is refreshed or accessed.
This mode is particularly useful when working with large datasets that are constantly updated or for real-time analytics where up-to-date data is essential.
Benefits of DirectQuery
- Real-Time Data Access: DirectQuery ensures that the data being queried is always up to date, without the need for periodic refreshes.
- Handling Large Datasets: When datasets are too large to import into Power BI, DirectQuery provides a viable option to work with big data while bypassing the memory constraints of Power BI.
- Reduced Data Redundancy: As the data is not duplicated or loaded into Power BI’s memory, there is less risk of maintaining multiple copies of the same data across systems.
- Live Connections: It allows users to interact with live data, making it ideal for scenarios where real-time analytics are required.
However, it is essential to note that using DirectQuery may sometimes result in slower performance compared to importing data, as queries are being processed on the source system rather than within Power BI.
What is Microsoft Dataverse?
Microsoft Dataverse is a cloud-based, scalable data platform built to support apps and processes within the Microsoft ecosystem. It allows businesses to securely store and manage data that can be used across a variety of Microsoft applications, including Dynamics 365, Power Apps, Power Automate, and Power Virtual Agents.

Dataverse also supports Common Data Model (CDM), which provides a shared data schema for consistent representation of data entities across applications.
How Does DirectQuery Work with Dataverse?
Power BI offers several ways to connect to Dataverse. One of the most powerful methods is using DirectQuery. By leveraging DirectQuery with Dataverse, users can access data directly from the Dataverse platform in real time, without the need to import or duplicate the data into Power BI.
Steps to Connect Power BI to Dataverse Using DirectQuery
- Set Up Dataverse Environment: Before connecting Power BI to Dataverse, ensure that you have a valid Dataverse environment within your Microsoft environment. This environment should contain the data entities that you want to query using Power BI.
- Open Power BI Desktop: Launch Power BI Desktop to begin the connection process.
- Get Data from Dataverse: In Power BI Desktop, go to the Home tab and click on Get Data. From the list of data connectors, select Dataverse.
- Select DirectQuery Mode: Once you’ve selected Dataverse, you will be prompted to choose your connection mode. Select DirectQuery to connect to the Dataverse data source live without importing data.
- Authentication: You will need to authenticate using your Microsoft credentials to connect to Dataverse. Ensure that you have the necessary permissions to access the data within Dataverse.
- Select Tables and Data: After authentication, you can choose which tables or data entities to query. You will have access to the same entities and data models that are available in Dataverse.
- Build Reports and Visualizations: Once the connection is established, you can start building reports and dashboards directly in Power BI using live data from Dataverse. Any changes in Dataverse will be reflected in real time in Power BI reports.
Benefits of Using DirectQuery with Dataverse
1. Real-Time Access to Dataverse Data
One of the most significant advantages of using DirectQuery with Dataverse is the ability to work with live data. Power BI queries Dataverse directly, which means that any changes made to the data in Dataverse are instantly reflected in your Power BI reports. This is ideal for real-time analytics, such as monitoring customer interactions, sales data, or inventory updates, where up-to-the-minute information is required.
2. No Data Duplication
With DirectQuery, there is no need to import data into Power BI’s memory. This eliminates data duplication and ensures that your organization’s data remains centralized and consistent in Dataverse. As all queries are sent directly to Dataverse, the process avoids any inconsistencies that might arise from periodically importing and updating data in Power BI.
3. Large Dataset Handling
Dataverse is designed to store large volumes of data, and Power BI’s DirectQuery mode ensures that you can access large datasets in real time without worrying about the performance issues associated with importing massive data into Power BI. As the data resides in Dataverse, Power BI can query this data efficiently, leveraging Dataverse’s built-in scalability.
4. Security and Governance
Dataverse inherits the robust security features of the Microsoft Power Platform. When you use DirectQuery with Dataverse, the same security rules and role-based access control (RBAC) that govern access to Dataverse data apply. This means that only authorized users can access and visualize the data, ensuring compliance with organizational and regulatory security standards.
5. Streamlined Integration with Other Microsoft Tools
As part of the Microsoft ecosystem, Dataverse is tightly integrated with other Microsoft tools, such as Power Automate, Power Apps, and Dynamics 365.
