Commitment Item Group Based FM Budget Report

Dear Experts,

In FM we can execute budget reports for Commitment Item Group through FMB_B01, FMB_B02, FMB_PT01, FMB_PL01 or FMRP_RFFMEP1AX etc.

All of these reports show Commitment Items balances on individual basis but nothing about total balance of group of these.

Considering a scenario; there are 3 Commitment Items 'CARRIAGE_VAN', MOTOR_BIKE' & 'BICYCLE' which are grouped under a C.I. Group "VEHICLES". Requirement for budget report is to show C.I. Group total on top and its individual Commitment Items totals below it.

For Example:

I have already explored GRR2 -> 4FM but can't find any characteristic value for Commitment Item Group.

Please recommend the solution (either Standard Report, Report Painter or Customization) to meet the requirement.

Regards
