PCR for Absence Days from Infotype 2001

Hi

I want to print Absence Days from infotype 2001 on the payslip. We have configured our payslip through PE51 HR form Editor.

I have tried adding the fields through PE51_checktab. But have been unsuccessful.

I am trying to write the PCR for the same but need a clue as to how to read the Calander days from infotype 2001.

Kindly help.

Regards

Spardha
