/456 (Tax deducted so far)

Hi Friends

Iam facing with a peculiar Problem i.e

My system is not generating the /456, Which is Tax deducted so far.

Due to this /460 (monthly income tax) is generating wrongly for every month.

Its not a problem with Schema changes since its happening for few PERNRs only.

Can any one tell me Where exactly went wrong.

Waiting for your Reply.

Thanks & Regards
