payroll monthly factoring, Valuation Base issue

Dear All,

I have an issue with payroll monthly factoring. The issue is the if I hire an employee at, lets say 15.07.2008 and run his payroll for the 7 month, he should be paid half his recurring allowances that r part of his gross.

I have given this employee gross salary of 3,851/-. He is suppose to be working 173.33 hours a month, as per 0007. The valuation base (/001) is coming up as 24.069, that is in accordance with monthly working hours 160.

In short, this employee should be paid half the salary but he is being paid more then that, that is 2176.652/-. What could be the reason? I am using /801 factor in Mark wage types for monthly factoring for all my wage types that are part of gross.

Can someone please help me out of this problem.

Regards.
