Hi,
I have trying to complete the Medical costs for 2 days now and I can figure it out. I created the list of roles:

Created EMP003 Employees-imported employees by roles data

Added Roles to SYS08 then imported the txt:

I try to amend the formula to take in EMP003 annd SYS08 Roles
Medical costs - IF Employed? THEN 'EMP003 Employee Drivers By Role'.Medical[LOOKUP: 'SYS08 Employee Details'.Department, LOOKUP: 'SYS08 Employee Details'.Role] ELSE 0
It keeps failing saying format of mapping used for lookup doesnt match any dimension of the source
