half day los of pay is not calculating in salary

hi friends

we r running time with without time evaluation. and its negative time management . we r only uploading absence type.

we have created 1/2 day loss of pay , for which i have assigned this wagetype to valuation rule which is unpaid . time wagetype valuation.

but if i m booking this 1/2 day LOP system is not deducting the salary for 1/2 days.

for full day its calculating properly based on calender day.

plz advise me who to deduct half day salary

thanks.
