Reversal of Import Duties

I need a help regarding reversal of Import Duties on posted Import Orders. It will not reverse the whole document at a one go but it reverses the proportionate amount of Item quantity which user will give as per the need for a perticular posted import document. The reverse entry will take effect on G/L Entry, Duty Entry and Value Entry table as well, accordingly.

Chome Che You should post it in Indian forum.
