Hi,we are facing issue in BYD under taxes-development of assessable value.

our client requirement is ,we developed one assessable value extension  filed according to their requirement,asessable value field is enabled for countervailing duty under taxes.

similarly,they are asking to enable assessable value field  to basic customs duty ,apart from the calculations,in few cases they are using like this scenario.

Is this possible to enable assessable value field to the basic customs duty under taxes tab?

please provide solution

Thanks and regards,
