Entering Labor Units in P6

Hi There,

Suppose we have an activity havig Duration=10DAys,

Calender is 8hz/Day & 6 Days/week.

" 4 " Skilled Labors are required each day for the activity to complete.How will we assign the "Skilled Labor"resource to activity,

Please tell me which option is correct from following,

1. Will Resource of "Skilled" Labor be assigned Separately 4 Times  i.e 8h/Day ,4 times.each time showing one Skilled Labor and "4" times showing 4 labors.    Or,

2. We will assign Resource of "Skilled Labor" Collectively  i,e 4*8=32 h/Day???
