Hello @Jack.Pennypacker. I have done this and I am attaching the BAQ that we currently use. I did not use a sub-query for the total received against the PO’s because the analysis is done at the PO release level. You will want to look for the calculated field “RemBal”. The BAQ has an optional parameter only for Supplier ID, but you could easily add a similar one for Product Group, or just use the standard filtering after the query executes.
Hope this helps. I can upload the dashboard, too, if you want it.
Regards,
