Transfer of legacy payroll data to SAP

Hi All,

Can anyone tell me what are the steps to be followed in transferring legacy payroll data onto SAP.

I know we have to have the config data in tables T558B, T558C, T5U8C. Then, I guess we have to run the payroll with schema ULK9 & U000.

But, am not sure of the complete process involved.

Someone please let me know.

Thanks in advance.

Parvath.
