Dear all,
I try to setup sales tax rounding in sales tax code where the round off is 1.00 and rounding form is 'rounding-up' as picture below

then I create a transaction in PO and I input the sales tax group and item sales tax group.
one of the transaction has a value 736.843,00 with the sales tax 5%. the calculated sales tax amount before rounding is 36.842,15 and after rounding up (as setup above) the calculated sales tax amount is should be 36.843,00. but the fact that I found is the calculated sales tax amount is 36.842.00 as pict below:

*except line 2, the other lines of this PO have true calculated sales tax amount after round-up. based on transaction above I have a simulation for calculated sales tax amount before and after round up as pict below:

but in transaction above, the other lines except line 2 the 'calculated sales tax amount before round-up' have a value above 5 in decimal. in fact, I use rounding form 'rounding-up' but for the value 36.842,15 it shows 36.842.00 after round-up, not 36.843,00
any help?
thank you
