Work with your system administrator to add the appropriate code group and membership conditions for your Reporting Services extensions."</P><P>&nbsp;</P><P>If so, try editing&nbsp;rssrvpolicy.config file located at</P><P>x:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer</P><P>to configure permission for this assembly.</P><P>&nbsp;</P><P>You will&nbsp;see PermissionSetName="Execution" property under CodeGroup tag. This is default for every custom assembly added. If you change it to FullTrust (beware its case sensitive), all custom assemblies will run under "FullTrust" permission.</P><P>&nbsp;</P><P>If you want to set permission to specific assembly here is a guide from Microsoft Docs:</P><P>"You can associate your own custom levels of permissions for custom assemblies that you use with reports. For example, if you want to allow an assembly to access a specific file, you can create a new named permission set with specific file I/O access and then assign the permission set to your code group.</P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P><LI-CODE lang="markup">&lt;CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="FullTrust" Name="MyNewCodeGroup" Description="A special code group for my custom assembly."&gt; &lt;IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer\bin\MyCustomAssembly.dll"/&gt; &lt;/CodeGroup&gt;</LI-CODE><P>&nbsp;</P><P>&nbsp;</P><P>"</P> Wed, 24 Jun 2020 14:14:03 GMT https://community.fabric.microsoft.com/t5/Report-Server/Error-while-configuring-custom-security-on-power-bi-report/m-p/1179581#M14746 saglamtimur 2020-06-24T14:14:03Z https://community.fabric.microsoft.com/t5/Report-Server/Error-while-configuring-custom-security-on-power-bi-report/m-p/1192048#M14829 <P>Still we are facing the below error,&nbsp;</P><P><img /></P><P>can you please suggest how to approach with this issue.</P> Tue, 30 Jun 2020 11:15:42 GMT https://community.fabric.microsoft.com/t5/Report-Server/Error-while-configuring-custom-security-on-power-bi-report/m-p/1192048#M14829 Anonymous 2020-06-30T11:15:42Z
