During our Power BI training sessions, one of the most frequently asked questions by participants is: How can I use a report to add records to my data table connected to the report? Or, if I do that, will it modify or damage my company’s data?
Let’s break some myths: Power BI reports are designed primarily for data visualization and analytics, rather than direct data entry or data modification.
Power Query, which is part of Power BI, does not modify data sources directly. It is primarily a tool for data extraction, transformation, and loading (ETL). It allows you to connect to data sources, perform transformations, and load the processed data into destinations such as Power BI or Excel. The original data source remains unchanged unless you explicitly export the transformed data back to it.
However, if you want to implement a “write-back” capability—modifying or adding data back to a database or source system—there are a few approaches you can explore:
Using Power Apps:
• Power Apps can be embedded into Power BI reports. Both Apps are part of the Microsoft Power Platform.
• You can create a form or interface in Power Apps where users can input or modify data.
• This data can then be written back to a database (like SQL Server, SharePoint, or Dataverse).
Custom Visuals with Write-Back Functionality:
- There are third-party visuals available (such as PowerBI visuals) that enable write-back capabilities. These visuals can connect to your data source and allow you to update or add data directly.
Using REST APIs:
- Create a custom app or process using Power BI’s REST APIs. These APIs allow interaction with your data source, where you can programmatically update data.
R or Python Scripting:
- Use R or Python scripts within Power BI to handle write-back operations. These scripts can connect to your data source and execute update statements.
Ensure you have the proper data gateway and security protocols in place.
Direct Database Connections:
- If you have a direct connection to your database (such as SQL Server), you can implement triggers or procedures that accept input data from Power BI or external interfaces.
