C4C Service - handling expense posting

Hello,

Scenario: technician will add expenses into the service request in C4C, expenses can be petty cash, business trip etc.

We just need to add actual expenses (not price) to the internal order in ECC but unable to identify the material type to be created in ECC (to replicate/map in C4C) - what material type (UoM, type, category etc.) should be created in ECC ?

Additionally, i am also assuming that the actual expenses will be added into the items cost condition type in C4C - correct me if i am wrong.

Haseeb.
