Power BI is already the market’s leading tool for business intelligence and reporting.
But its default setup is limited to one-way data flows. In this article, you’ll learn how to set up a writeback tool in Power BI step by step, so your users can input and adjust data directly within a Power BI report.
We use the Power ON Visual Planning in this specific example. This writeback setup guide covers everything from preparing your data model to configuring reports and testing the process, giving you a practical roadmap to make Power BI a true two-way planning and forecasting solution.
Key Takeaways
- Power BI doesn’t support writeback natively. However, you can add it externally using tools from several different vendors in the market.
- Writeback turns Power BI from a static reporting tool into a dynamic and integrated planning solution.
- Use writeback to update forecasts, create new scenarios and adjust existing scenarios, and update reports with real-time inputs.
- Setup involves data modeling, configuration of connection strings, and add and configuring writeback enabled custom visuals.
- Writeback is essential for planning, budgeting, forecasting, and real-time decision making.
Why Writeback in Power BI Matters
Power BI is one of the best tools for reporting and analysis, but out of the box, it’s a one-way street. Data flows in, but you can’t push new values back into your source in real-time. For finance, planning, or operations teams, that creates a bottleneck.
Writeback changes that. It makes Power BI interactive: users can enter, edit, and adjust data directly in reports. That means forecasts, plans, and corrections happen in real time, without jumping between systems or waiting for IT.
For finance and operations leaders, it’s the difference between static reporting and dynamic planning.
Here’s the full step-by-step walkthrough. We cover the entire process of configuring writeback in Power BI:

How to Enable Writeback in Power BI
Here’s the high-level process, stripped of vendor-specific details.
1. Set Up Your Data Source:
- Ensure you have a relational database (SQL Server, Azure SQL, Oracle, Snowflake, etc.).
- Create the necessary tables and load sample or production data.
2. Build Your Data Model:
- If using Power BI Pro: model in Visual Studio + Analysis Services.
- If using Premium Per User (PPU): model directly in Power BI via XMLA endpoints.
- Define relationships, measures, and hierarchies.
3. Design the Report:
- Connect Power BI to your SQL or other database.
- Build key visuals (matrix, charts) with measures like Sales or Quantity.
4. Configure Write-Back:
- Import a write-back visual (e.g., Data Entry Matrix).
- Connect the visual to your database via secure connection strings.
- Enable editing features like commenting, formulas, and data entry.
5. Test & Monitor:
- Validate updates in your source database.
- Review audit trails and ensure security permissions are correct.
- Set up monitoring dashboards to track write-back quality and performance.
Practical Benefits of Writeback
- Forecasting & Budgeting: you can enter updated numbers directly into the report in real time.
- Scenario planning: test new assumptions on the fly.
- Error correction: fix mistakes without waiting for IT refresh cycles, self-service and independent work.
- Collaboration: multiple teams can adjust shared plans in real time.
Common Pitfall to Avoid
- Skipping governance: always set clear user roles (who can edit vs. who can view).
- Security: connection strings must be stored securely.
- Performance: keep writeback visuals simple – complex logic should belong in the data model.
FAQ About Writeback in Power BI
What is writeback in Power BI?
Writeback enables users to input and save changes from Power BI directly into a database, turning reporting into a dynamic and interactive planning process.
Do I need Premium Per User (PPU)?
PPU is recommended. It simplifies modeling and reduces infrastructure overhead. Pro users can still implement writeback, but in this you need a data model deployed in Analysis Services.
Should I use DirectQuery or Import mode?
For large datasets, DirectQuery provides real-time updates. For smaller data, Import is fine.
Is it secure?
Yes, if configured correctly. Ensure connection strings, roles, and access controls are managed by IT admins.
Does it work with any database?
Most relational databases (SQL Server, Azure SQL, Oracle, Snowflake, etc.) are supported by major writeback solutions.
How do I maintain data integrity when multiple users write data?
Ensure the writeback service manages row versioning or locking so simultaneous updates don’t conflict. Apply audit trails to track who changed what, and use conditional logic to validate changes before commit.
How to implement writeback on my own?
While technically possible, implementing writeback requires more than just adding a visual. It involves database configuration, connection strings, security alignment, and workspace setup.
Without prior experience implementing writeback tools, projects often hit roadblocks (e.g., mismatched row-level security, performance bottlenecks). That’s why most organizations work with external consultants who have delivered writeback in multiple environments. This ensures a smooth implementation and avoids costly mistakes.
Can Centida help with the implementation of writeback solutions?
Yes. At Centida, we specialize in implementing writeback solutions in Power BI. We guide clients through the entire process: covering both business requirements and technical setup, ensuring the solution is secure, scalable, and easy for your team to manage.
