personnel number cost center

Dear All,

My requirement is I wanted to track personnel number wise expenses.So I am assigning cost center to personnel number through PP01 (A 011).System is picking up cost center correctly in PA30 but now when I am passing FI entry & when I give personnel number to that GL, system is not picking cost center maintened in PA30.

Why it so ? Is there any other customisation I have to do ?

Regards,

Abhijit
