WBS Original Budget versus Approved Budget

Dear Experts,

In a Project, I have original budget of 100 INR for a WBS element, If customer may approve 80 INR or 120 INR.

This 100 I can show in CJ30 original budget column now where this approved amount I need to show?

Because user wants to see Original Budget and approved budget column in a report.

Please Suggest

Thanks,
