PP reports

Recent-ally we have implemented PP module at our client place without any custom object...Now client started using this functionality....Now in second phase we want implement some custom reporting which would be good for them. Can you please suggest useful reporting which you hae worked in your exp & are not part of standard SAP but we can implement to get good information.

Let me give you some background about process which we implemented here..

They are in process business (chemical).

Part of PP we implemented standard solution; BoM, Recipe, Different process order type, order conformation, order costing, good receipt & GI for order...

Idea appreciated!!!!
