Access payroll variables from custom payroll function

Hi All,

I have a requirement to create a custom payroll function that returns some data from IT0006 and IT0032.

I have written the code in PCBURZDE0, as the payroll is for Germany, it does read the data needed.

My question is, how I can access the variables specified for the function in the payroll schema.

Schema definition in PE01

Zeile     Fkt        Par1  Par2 Par3 Par4 D Text

000010 BLOCK BEG                              Fahrradleasing

000020 _DFRD &PRO GEN

000030 BLOCK END

If I double-click Par1 for function _DFRD (&PRO), then I see he two variables I should write the data to:

Zeile  VarArg. FZ T Operation        Operation Operation Operation Operation Operation *

       -------------+---------+------------------+---------+---------+---------+---------+

000010                  AMT= PKWWRPRINT     *

000020           1     AMT= ENTKM  PRINT

So, as I understand I should write the two variables PKWWR and ENTKM, I have the values in the function code, but I don't know how to access these variables.

Thanks for your help!
