Form 16 Disabled

Hi,

I need to disable form 16 during payroll processing.

I know I can use proxy class and restrict access to entire application during payroll processing.

However, our requirement is that during payroll processing form 16 should be disabled only for this year.

Employee should be able to view Form 16 for previous year.

Is there any BADI / Enhancement point through which we can achieve this?

Regards,
