Hi Sai,
Perk is taxable (and probably this ESOP is belonging to whole financial year). So, tax is deducted. If you want to defer the tax deduction, you can enter this ESOP wage type at the end of the financial year.
Please let me know, what type of logic you want.
I want to know, have your tax liability increased by 11.11 % of perk amount? I am not sure.
Regarding 2nd issue (/127 not adding in next month), you may check the cumulation calendar (V_T54C3). You may also explore the logic in PCR X006 (processing class 6) for bringing annual cumulated value from the previous month result.
May also wait for experts' advice on this.
(Meanwhile, I will go through your aug RT attachments and will get back to you).
regards,
Bala.
