Dual Overtime Calculation

Hi,

I have special case, where we need to have two different Over time Calculation for different employees.

i.e 1.5% of wages as OT amount to some employees and 1.25% of wages to some employees.

Can you tell me how can we map this in sap, kindly provide the configuration steps in detail.

Points will be rewarded.

regards,

Kumara Vel.
