We are paying 500 per month as Children Education Allowance month to our employee. He is getting exemption of 200 per month.
Perk on COA would be 1000 (basic) + 600 (Special All) + 300 (500 - 200) CEA = 1900*7.5% = 142.5
If i tick the Cumulation Type 15 in the Table (v_512w_d) it will add all 500 in the basis to calculate the perk value , instead , we need to add the diff of CEA Amount minus exemption amount of CEA to the COA/CLA basis (/115) i.e. 300(500-200) .
