Freight booking with multiple Carriers - Charge calculation

Hello,

In S4HANA Public Cloud 2402, for Transportation Management -> We person a Freight Booking (Port to Door) with a main-carriage & an on-carriage stage, where 

Main-Carriage -> has an executing bearer (BP1) and a broker/freight forwarder (BP2)

On-Carriage -> has a abstracted executing bearer (BP3)

Since successful this unreality version, we truly cannot cipher charges successful roadworthy FO created for on-carriage, however to execute the complaint calculation to hap for each 3 carriers (BP1, BP2, BP3) successful the freight booking itself?

Rgds,

Anjani
