report builder refresh

[powerbiexpert22]

does report builder imports data (like power bi desktop) when we connect it with excel located on sharepoint folder or it works like directly query?

Hi @powerbiexpert22 ,

Power BI Report Builder does not import the data like Power BI Desktop. When you connect it to an Excel file stored on SharePoint, it behaves more like a DirectQuery connection:

• The data is queried live from the Excel file each time the report is run.

• Report Builder does not store a copy of the data internally.

• This ensures that your report always reflects the latest data in the Excel file on SharePoint.

Key difference:

• Power BI Desktop: By default, imports data into its internal model (unless DirectQuery is used).

• Report Builder: Always fetches data on-demand from the source.

This is important for performance and real-time reporting considerations.

Hey @powerbiexpert22,

Report Builder operates on a direct query model when connecting to Excel files hosted on SharePoint, similar to live connections rather than data import functionality.

Key Points:

• Live Connection: Report Builder establishes real-time connectivity to the Excel file on SharePoint
• No Data Import: Unlike Power BI Desktop, no data is cached or stored locally within the report
• Dynamic Refresh: Each report execution pulls current data directly from the SharePoint source
• Performance Consideration: Query response time depends on SharePoint server performance and file size

Recommended Solutions:

• Optimize Data Source: For large datasets, consider migrating from Excel to SQL Server or Azure SQL Database for better query performance
• Configure Timeouts: Adjust report execution timeout settings to accommodate SharePoint response times
• Permission Management: Verify that Report Builder service accounts maintain appropriate read permissions for the SharePoint directory
• Implement Caching: Enable report-level caching for scenarios where data updates are infrequent to improve user experience
• Monitor Performance: Track query execution times and implement data source optimization if response times exceed acceptable thresholds

Additional Considerations:

• SharePoint connection stability may impact report reliability
• Network latency between Report Builder server and SharePoint can affect performance
• Consider implementing error handling for connection timeout scenarios

This approach ensures data freshness but requires careful performance tuning for optimal user experience.

Hi @powerbiexpert22 

• Report Builder does not store or cache the Excel data inside the .rdl file, every time you run or refresh the report, it queries the file from SharePoint in real-time. (i.e works like Direct Query)
• I have had the same requirement: If you want it to behave more like Import, you’d need to point Report Builder to a prepared dataset in a Power BI semantic model instead of the raw Excel.
