Excise Rounding (LCY)


I have a problem with Excise Rounding.

I am using LCY for a sales order . Here i am calculating the excise value for each item in the order. I would require to round the excise amount only for the final excise amount. For that i have given the Excise Rounding Precision as 1.00 and Excise Rounding Type as Nearest in the general Ledger Setup.

After i calculate the structure values in the sales Order , when i press F9 , i can see the final excise amount . However when i calculate the excise amount Item wise, i got to know that the excise amount i got in the statistics screen is calculated after the item wise excise rounding.

Is there any possible way to get only the final excise amount rounded rather than considering each items for the rounding.?
