Is possible to create a Grouped and Stacked Chart like this in iReport?

Not exactly, you can do stacked bar charts but you cannot group bars with iReport alone.

You can however, use chart customizers like this or otherwise implement any JFreeChart feature with code.

Or if you don't mind missing the spaces, for the category expression use

"Product " + $F{ProductNum} +  " " + new SimpleDateFormat("MMM yyyy").format($F{Day})
