Rounding / split payment

Hi Guys

We have a problem if we want to calculate TAX amount. I f we have a an invoice billed in EUR but tax must be paid in PLN in tax sheet there is a calculation and if we have a 0,01 differnece we can’t change it. It’s something like “force” rounding. We know that it’s possible to turn off in SAP this  and that it’s standard option. Any ideas?

We have a many issue because of this difference, on AP, payment and GL level.

Thanks in advance
