Hello all, I have been trying to work through Model Building Activity level 6 and cannot seem to understand why my lookup formula is off. I am trying to add a formula to REP04 that shows Total Salary expenses by Region and Role. The formula I am using is 'EMP02 Employee Expenses'.Salary[Lookup: 'SYS08 Employee Details'.Region, Lookup:'SYS08 Employee Details'.Role] but it receives an error. How I understand it is that 'REP04 Employee Expense Summary'.Salary is my target and 'EMP02 Employee Espenses'.Salary' is my source module. Because EMP02 does not contain Region and Role I need a mapping module/s to achieve my goal. I am trying to use 'SYS08 Employee Details'.Region and 'SYS08 Employee Details'.Role for mapping but receive an error. What am I missing? Do I need to be using a different module? If more details are needed please let me know. Thanks for any help! Error message: Format of mapping used for lookup doesn't match any dimension of the source Helpful reference post I believe is relevant: https://community.anaplan.com/t5/Academy-Training/Altering-Line-Item-Formula-with-lookup/m-p/88856#M2524 Screenshots:
