Custom Rendering Extension in Power BI Report Server
Hi Vishal-Sepaia_m ,
Power BI Report Server does not support custom rendering extensions, unlike SQL Server Reporting Services (SSRS). This limitation is the reason behind the following error:
rsRenderingExtensionNotFound: You have attempted to use a rendering extension that is either not registered for this report server or it is not supported in this edition of Reporting Services.Workaround Options:
Use the built-in export formats (e.g., CSV, Excel, PDF).
Perform any required custom formatting (such as converting CSV to tab-delimited) externally using PowerShell, C#, or other tools.
If custom rendering extensions are essential to your use case, consider hosting your .rdl reports in SQL Server Reporting Services (SSRS) 2019 or 2022, which does support custom rendering extensions.
Note: While modifying RSReportServer.config and deploying custom DLLs works in SSRS, it is not supported in Power BI Report Server 2022, even though the folder structure and configuration files appear similar.
