Only I can see the Barcodes in html view. Users are not able to see the barcodes even in html view.

I want it like a hierarchical column. Suppose I have client XYZ and the Sales is 100$ when they click on XYZ they should see like Category 1=20$, Category 2=80$. I did a drill down report right now. But they asked if this can be achieved, instead of going to different report when clicked and return back to main report.
