Unmesh,

OpenERP comes up with the feature of child taxes! You should use it for your aim.

Thanks.

Thanks for your reply
i have already tried with child taxes but unbale to achive my requirement.my requirement is like

I have ProductA with the price as 1000

The packing and forwarding charge (Additional Charge ) is 2.5 % of the Product A price( Can not include as part of Product as it need to be shown separately in the invoice)

The taxes need to be calculated by considering the base price as 1025 (1000+2.5%)

I have following taxes which need to be calculated on the base price

Excise duty of 10% (on the base price of 1025) = 102.5
Education Cess tax of 1.5% (on base price of 1025) = 15.37
Secondary Education Cess tax of 1.5% (on base price of 1025) =15.37

Total price =1158.24
Sales Tax of 16% on the total price = 16% of 1158.24 = 185.31

Total Invoice Value (1158.24 + 185.31) = 1343.55

I would appreciate any help in calculating the prices in the above said steps in the invoice

Plz help me

regards
