Regarding Tax Setups and Rounding Changes in Oracle EBS due to Japan Tax Laws

Product : Oracle EBS

Version: Product Version11.5.10.2

Operating System: Linux x86

OS Version: Oracle Linux 6

Currency Used: Japanese Yen

Due to change in Japan Tax Laws, there is rule in system to be added that rounding off on the Tax Amount should be performed only once i.e., on the total amount and not on each line.

Currently Rounding is performed on TAX at each line level which we need to limit it to adhere Japan Tax Laws planned from October 2023.

Also, when implementing this we need to prevent decimal Currency in Journal Entries.

Would need your advice if there is any way to limit the rounding off at each line and perform the rounding only once at totals.
