How to create or run a report showing all customer orders with received PO for showing the amount invoiced to date?

Hi!

Sage Intelligence Reporting is fairly new to me...I'm not even sure if I need to use IR to get these reports.  Has anyone every ran a report or created one that shows all customer orders with received Purchase Orders that shows the amount invoiced to date? 

Also can someone tell me how to do a report that shows all open supplier orders?  

Lastly... a report showing inventory items and "bills of material" for assemblies?

Any help on any of these reports would be greatly appreciated.
