Incorrect Rounding at invoice Line for the withholding invoices

Hi Experts,

For the single invoice line there are multiple distributions wherein the tax is showing the major variance. Below quoted example which gives you the clear understanding.

We have created two withholding tax codes( each 1%) and assigned to group, and these group we have assigned at the invoice line level.

Invoice amount is 2670022 and there are multiple distributions for the invoice. After validating the invoice each withholding tax line shows as 26707 which is incorrect actual the value should be 26700.22 by rounding it should come to 26700, but we see Rs.7 as variance.

Can anyone please suggest is there any specific setup needs to be modified or any other solution to fix this..
