Accounts payable

HI,

I want to create a AP voucher where tax amount need to paid to govt. So it should create 2 record in F0411- one for supplier and another for govt.

Say for example goods purchase cost Rs. 100 + 14 % tax = 114 /- out of which Rs. 100 need to paid to supplier and Rs. 14 to govt. I used tax explanation code as U. But it create only 1 record in F0411. can anyone let me know how to pass such record?
