Report Writer Reports

Hello Experts,

Our Business Analysts want to include some of the 'Report Writer Reports' into the 'Reporting Tree' of SAP Standard Menu.

For eg into the following path: Accounting->Controlling->Product Cost Controlling->Cost Object Controlling->Product Cost by Order->Information System->Reports for Product Cost by Order.

I have no clue of how to do that. Can anybody please help me. We are using 46c.

Thanks a lot.
