When the VAT is calculated there is difference of 1 cent. It is also observed that in some invoice the line with same base amount have VAT calculated wrongly in 1 line and its correctly calculated in other line.

The product team found the root cause as, The tax amount is calculated by summed line amounts first. then allocate the total tax to every line with the line percentage of the line. This is the reason for the value differences in the tax form.

This should not happen, and MS should fix this logic.
