child education allowance exemption amount

Dear Guru

We observed that chiled education allowance is claimed for Rs 2500/- ( Annually allowance ) in the month of May-2012 , as per

defined examption limit system should show examption of Rs 1200/- but system are considered exemption of Rs 1100/- (one month less )

please note that we have maintained the details in table V_T7INT9 frequency limit for exempiton is annual

Also note that in the IT 582 we have maintained date of origin 01.04.2012 ( But maintained today itself )

So pl suggest how system will considered exemption of Rs 1200 instead of Rs 1100/-

Regards

Vijay
