When i create additional charge lines with the octroi applicable checkbox ticked... then also the amount of the additional charges like freight and packing charges do not get included in the calculation of octroi.

For eg:-

1. say the order amount is 100
2. i add an additional charge line of freight 10 with the octroi applicable checkbox ticked.
3. now i add an additional charge line of octroi 5.5 % .

Now the octroi amount shown is 5.5. It should be actually be 5.5% of 110.


Please help me out.
