HRA Tax exemption

Hi Experts,

There is a requirement in India payroll to get tax exemption of 50 % on basic salary even though it is a class II city. For that the value in table V_T7INR3 with code NMHRA to be changed manually,whereas I suspect it may create any other issues if changed manually.

Is there any other solution possible for this situation,please guide in this regard.

Regards,

RK.
