Most of these reports are using Cascading parameters. For example, we have a ClientNo parameter, it is a dropdown menu. When the user is selecting it, the dependent date parameters are filtered based on the ClientNo. And when the ClientNo is changed, the date values are refreshed based on the new ClientNo.</P><P>But unfortunately, after we updated the Report Server to January 2021, this functionality is lost. The dependent parameters are not refreshing when the parent parameter is selected or changed.</P><P>I searched a lot on the web, and I tried almost all the answers, but none of them seems to work.<BR />Consider this, that we have at least 100 reports, and we can not apply a fundamental change to all the reports. ( cause some of the solutions were suggesting to set the parameter data sets to a stored procedure .... )</P> Fri, 26 Feb 2021 09:59:33 GMT Anonymous 2021-02-26T09:59:33Z https://community.fabric.microsoft.com/t5/Report-Server/Power-BI-Report-Server-January-2021-update-Cascading-parameters/m-p/1691791#M18311 <P>Hello dear Community,</P><P>I need your help.</P><P>We have many reports (.rdl) in PowerBI Report Server.
