Customize/modify BBP_BW_SC3

Dear experts,

I have a requirement to support searching of SCs using 4-new fields in the report BBP_BW_SC3.

1) Can this be done by enhancing the current report?

If so how can we modify the search criteria and the search results of the FM- BBP_BW_SC_SELECT_1.

2) I need to create a Z-report and customize according to the customer needs?

Regards,

Vipra.
