L1 Model Building Exam- Activity 5


This is such a painful model building activity and worst part is it has no hints. Been stuck at it for 3 hours now. Can anyone please help map the formulas for bonus, car costs, phone costs, medical costs, etc. in the EMP 02 Employee expenses module from EMP03 Employee drivers by role module. I'm getting foll error as "Format of mapping used for lookuo doesnt match any dimention of the source"

Also, what does it mean by "employee costs will be driven by their job role and department"?
