I have a report where I am grouping by Main Client, Client, Year, Quarter, Month, Date and Day. I have a request to add a new field after the client field called Hierarchy then I have to apply the column visibility in the Hierarchy field.
=iif(parameters!ShowAllClientMetrics.Value="true",False,True)
When I attempt to add the column visibility expression on the new grouped field Hierarchy the column visibility is grayed out. I need an understanding why column visibility expression is not allowed in the grouping area and is there an alternative way to apply the column visibility expression on the new field?
