Tax rate area with 3 decimals and tax calculation

Hello,

JDE 9.2 Contract Billing - Tax rate setup in F4008 as 9.975%. This tax rate is used to calculate the invoice print through R48507. But the JDE calculation in F4822 and F03B11 results in a slightly different amount than what is calculated on the invoice based on tax setup of 9.975%. This creates a difference between JDE calculated tax and the invoice print.

So how does JDE calculate the taxes and any ideas on how this can be managed?

Thanks
