Primavera P6 Exercise

Hi All,

I have an exercise that is set around manufacturing (not experienced in Manufacturing) and has a requirement to produce, say, 6 laptops. Each unit is identical in terms of process, i.e. Procure materials, manufacture & assembly, Inspection & testing, then acceptance. 

Question: Would you generally create the schedule for unit/laptop 1 then copy & paste activities  into seperate WBS elements, Unit 2, 3, etc. or just create a simple Unit 2-6 with a start/finish date rather than detailing all remaining units?

Thanks
