Hi Rakesh,
For the arrear wage type you will creat two wage types . i.e Carry Forward and Brought Forward. Two make personal pay's arrear wage type you take the basis pay carry forward and brough forward model wage type from system.
After that you have to add these wage type in the IN42,IN43 & IN44 pcr. In your case it would be customer specific pcr i.e Z or Y. Check and do the necessary changes in that.
Suppose i am taking your carry foward wage type is 4000 and brough forward wage type is 5000. where Personal Pay is 3000
then PCR design would be,
IN42
3000
ELIMI *
SUBWTD4000
IN43
3000
ELIMI *
ADDWTD4000
IN44
4000
ELIMI *
ADDWTE5000
This arrear wage type 5000 will be add in the earning part of the payslips and also add to gross earning. If you are suing PE51 for payslips design then WT5000 will be add under windows id section and cumulation ID section.
Check and tell me.

Sankarsan
