Rounding Off Price in Purchase Order

Dear All,

My client wants 6 decimal places for Prices. I customized the EDT for AmountCur and set it to display 6 decimal places. I have configured in Currencies the rounding rule and have also set in trade agreement a purchase price of 6 decimal places. My units are also configured to 6 decimal places. Nonetheless, in PO form, it automatically populate the unit price rounded to 2 decimal places. I'm running out of places to configure, any ideas? I need it not to round off. I have come across this and i agree that ax should cater decimal places greater than 2.

Thank you,

Lyka Tasis
