# [Fabric & Power Apps: Overcoming Data Write-Back Roadblocks! (Integration Guide)](https://pragmaticworks.com/blog/fabric-power-apps-overcoming-data-write-back-roadblocks-integration-guide)

 Written by [Manuel Quintana](https://pragmaticworks.com/blog/author/manuel-quintana) | Jul 02, 2026

In this insightful video, [Manuel Quintana](https://pragmaticworks.com/instructors/manuel-quintana) from **Pragmatic Works** explores the integration challenges and opportunities between **Microsoft Fabric** and **Power Apps**. The primary focus is identifying roadblocks when attempting data write-back within Power Apps and how Fabric’s different storage options can impact success.

 

#### Read-Only vs. Write-Back Scenarios

Manuel begins by distinguishing between two core use cases for Power Apps:

- **Read-only scenarios:** Virtually all Fabric storage options work well.
- **Read-and-write scenarios:** These are more limited and present integration challenges.

#### Storage Options in Microsoft Fabric

Microsoft Fabric currently offers three storage solutions, each with varying support for Power Apps functionality:

1. **Lakehouse** 
     - Supports read-only access via SQL endpoints.
     - Does not allow `CREATE` or `ALTER` SQL statements.
     - Not suitable for write-back scenarios in Power Apps.
2. **Warehouse** 
     - Allows `CREATE` and `ALTER` statements.
     - Primary key definition must include `NOT ENFORCED` and `NONCLUSTERED` keywords.
     - Still does not enable write-back from Power Apps, despite schema support.
3. **Fabric SQL Database** 
     - Currently the only storage solution that supports full read/write capabilities.
     - Enables standard primary key creation without special keywords.
     - Best suited for Power Apps requiring data modification features like `PATCH` or `UPDATE`.

#### Connecting Power Apps to Fabric

Manuel outlines two main integration methods:

1. **Using Virtual Tables** 
     - Supports connecting to lakehouses and warehouses.
     - Provides read-only functionality.
     - Quick to set up via workspace and table selection in Power Apps.
2. **Using SQL Connectors** 
     - Connects to SQL endpoints for all Fabric options.
     - Only the Fabric SQL Database (not its SQL endpoint) enables write-back.
     - Be cautious: connecting via SQL endpoint will still result in read-only access.

#### Write-Back Demonstration with SQL Database

To prove the write-back functionality, Manuel demonstrates the following:

- Connects to a Fabric SQL Database using correct server and DB name.
- Creates a Power App using the external SQL data source.
- Updates a record successfully (e.g., changing “Leia” to “Manuel”).
- Verifies the change inside the SQL database within Fabric.

This confirms that Fabric SQL Databases are currently the only option that supports write-back operations.

#### Tips and Reminders

- SQL endpoints tied to lakehouses and warehouses are read-only in Power Apps.
- Be careful with overwriting tables—it may remove key constraints necessary for integrations.
- Always use the SQL database object’s connection info, not the SQL endpoint, when write-back is needed.
- Power Apps may eventually support write-back in warehouses—stay updated!

#### Conclusion

Manuel wraps up the video by encouraging users to explore the powerful combinations of Microsoft Fabric and Power Platform. While write-back capabilities are currently limited to Fabric SQL Databases, there’s ample flexibility for read-only integrations using virtual tables and SQL endpoints.

If you’re exploring the Power Platform for your business and want to build apps that modify data within Fabric, the Fabric SQL Database is your go-to solution.
