I cannot find a way to calculate the median for multiple columns of data presented in a single report.
I've tried to do it directly in the SQL Server code with PERCENTILE_CONT but there are compatibility level issues (level 100 though I use SQL Server 2017).
My preferred method was to do it through Custom Code following the instructions in: mean, median, mode in SQL Server Reporting Services which works to calculate the ONE median in the report, not multiple.
Does anyone have an idea?
