new VAT code configuration problem

Dear All,

Here as per our business scenario we have one tax/VAT code

example for

V1 -

> 1%

V2----> 4%

V3----> 12.5%

all these code are for raw materials and capital goods .

Tax G/L accounts are defined on state wise basis.

example : G/L --> 180000 for west bengal

180100 for bihar

180200 for delhi ...... so on

VAT code V4 for 20% has been newly created but we are unable to

assign the same to state wise G/L account .

please help us to solve the problem.

thanks

Amit
