Rounding Issue in IT759 Activation BADI & IT0008 create

Hi, I am trying to implement BADI -HRECM00_ACTIVATION~CALC_SAL_ADJUSTMENT

to arrive at the new value for new IT0008 creation. I want to round up the value of CPAMT / 24 (for semimonthly employees) that comes into this BADI and add it to the wagetype on old IT0008 and create new IT0008. I am expecting the new IT0008 to have the new wagetype value and the annual salary adjusted properly. But what happens is the wagetype in new IT0008 is changed but the annual salary is still the old ansal. There is a disconnect between these two. Please let me know if there is anything that I am missing.

Thanks
