How can i add a new characteristic to Sap standard InfoObject?

Hi Experts,

Please anyone let me know how can I add a new characteristic or a key figure into an SAP standard InfoObject in order to add it to the standard InfoCube? The situation is I would like to add region and business unit to the characteristics of the Industrial Hygiene and Safety. After that, I would like to add them to the InfoCube called Accidents: Person Involved [0EIH_C02] that is located in the MultiProvider called Accidents: Complete View [0EIH_MC01]. Is it feasible to do this way?

I just learned the BW/BI, so please help me with this. I would really appreciate your responses.

Thanks,
