SAP Notes for New Budget Changes

Hi All,

I want to apply one SAP Note "1361644" for new budjet changes of India Payroll.

Can anybody help me is it only one note or some more notes are there? and before applying the note what do i need to take precautions and after applying also as well. is there any costomizations are there? my client production system is ECC 5.0.

If i will not apply this note now is there any impact on my system, if i will apply next month what will happened.

Help me

Thanks
