Taxes amount not prorated.

Hi Experts,

We have configured tax for Sales and Use Tax (VS1 - Account Key). We need tax percentage to be 5% till mid November 2013. Then after that we need tax percentage of 7%.

Tax for 16-Nov-2010 to 15-Nov-2013 = 5%

Tax for 16-Nov-2013 to 31-Dec-9999 = 7%

So in configuration these tax rates are maintained with correct time slices.

But now when we bill customer with period where there is tax change in that period, system is not prorating tax amount. Here is how system is behaving

Suppose net amount it 100 - We are billing customer for period 01 Nov to 30 Nov (There is tax change starting 16th Nov).

System is applying 7% tax. it is not prorating to refect tax change.

Thanks,

Suhas.
