Invoice rounding to two decimal when line amount 4 decimal

Hi All, 

I want to round invoice value up to two decimal places when line amount have four decimal. How to do it on Dynamics NAV 2009 R2 ?

I found following areas on General ledger setup,

1. Inv. Rounding Precision (LCY)

2. Amount Decimal Places

3. Unit-Amount Decimal Places

** I have active the invoice rounding function in Purchase /sales setup also.
