Wrong Rounding

Hello all,

I have issue about Rouding.

My customer used LCY is VND and with VND always rounded
Example :

1255.01 --> 1255

Because the VND never has decimals.

My problem is : Amount Rouding Precision in GL setup is 0.01
and now all transaction in GL is rounded 0.01. This is WRONG!!!!

How can we change Amount Rouding Precision ? Because we already have transactions.

I want to know is there a way to fixed it legally? I mean that we can use the system function to do that??

Not use "Cheat" way : Close checked codes in Amount Rouding Precision, create a report to round all old transaction in GL, Detail Cust. Ledger Entries .......

My target is : Change Amount Rouding Precision.

Anybody can help me pls.

Thanks,
