Grouping SSRS tables in report

Question

I need a report presenting laboratory tests. I get several tests every day (different tables like Chem, Micro or Sub). I would like to be able to display them separately on each page - based on [SampleID] - but together with the corresponding categories (tables). So far, I was only able to display all the results on one page or grouped by tables, but then for example instead of 10 pages I have 20. How can I group it correctly?

The solution that interests me seems to be in this post How can I have multiple tables on one SSRS page that represents one value in SQL? . But when I follow the directions I get an error code "The tablix 'Tablix4' has a detail member with inner members. Detail members can only contain static inner members."

Answer 1

That's what I did, and it works, but only when the tables are in one row https://i.stack.imgur.com/sEMH9.png , but I needs them underneath the other - in this case, the tables display on separate pages. https://i.stack.imgur.com/vNeDo.png
