Confusion in defaulting TARIF feaure

Hi Friends

Please help me out ...I am confused on how to proceed with the TARIF Feature

My

Personnel Areas are H001, H002 and H003 (Geographical Areas)

Personnel Sub Areas are HB01,HB02,HB03 & HC01 & HC02 & HH01,HH02,HH03 (Departments)

Employee Groups are T,U & V (Permanent, Temporary & Contract)

Employee Sub groups are HD, HE & HF (Permanent Monthly, Temporary Monthly & Contract Hourly)

Pay Scale Type is 05

Pay Scale Area is 03, 04 & 05 (depending on Geographical areas)

I have done all other settings required but not sure how do I default the TARIF feature?

Thanks in advance
