Hi askrajeev 

Thank you for reaching out to Microsoft Fabric Community Forum.

 

This issue is commonly related to compatibility between the SAP BW system and the Power BI SAP connector after an SAP Kernel upgrade. Here are some bullet points that can help you troubleshoot and resolve

 

 

  • Confirm that SAP NetWeaver RFC SDK version installed on the Power BI gateway or client machine is compatible with the upgraded SAP Kernel.

  • Power BI uses the SAP .NET Connector (NCo) or SAP NetWeaver RFC Library internally; mismatches here can cause disconnections.

  • Ensure the SAP BW connection settings in Power BI are still valid post-upgrade (e.g., system ID, application server, instance number).

  • Check whether the SAP BW system now requires a newer SNC (Secure Network Communication) setup or certificate.

  • If you are using DirectQuery, test with Import mode to isolate if the issue is query-execution related or connection related.

  • Update the on-premises data gateway to the latest version if it hasn't been updated post-kernel upgrade.

  • Look at SAP application logs (ST22, SM21) for dumps or logs related to RFC or external system connections to identify exact issues.

  • Test the connection using SAP Logon Pad or SAP GUI with the same credentials — this can validate basic connectivity.

  • Check with your SAP Basis team whether RFC parameters or services changed as part of the kernel upgrade.

  • Use tools like SAP Gateway Ping or RFC SDK Test Tool (rfcexec.exe) to test raw connectivity from the Power BI machine.

  • Attaching Microsoft’s documentation on SAP connectivity with Power BI:
