factoring based on working days

Dear All

Actualy i need to prorate my basic salary bassed on the working days. the problem is now i can able to see the nomber of days in TASOLL is not a working days.

working days mean.. i have to reduce off days (daily work schdule class =0) and public holidays (holiday class = 1 and 3)

but in TASOLL.. its reducing only off days but not public holidays.

my expectation is. i want to take nomber of working days.. without consider off days and public holidays. how can i achive this?

I have tried buting day type valsu as 2 in both holidays.but still system reducing only off days and not public hilidays.

Can anybody help on this?
