Hello Mariano, I have been through the article you have shared. I am stuck in the part where I have to edit the query. I have created a report out of MSSQL store procedure by the follwing way; [reporting].[xyzproc] $P{param1},$P{param2}, $P{param3} --This is a way of calling store proc in Studio Now the article you have shared, asks us to use $X{IN,dbfieldName,CascadingParameter}, I am not able to understand how do I edit the [reporting].[xyzproc] $P{param1},$P{param2}, $P{param3} and use the multilist parameter
