Tax Summarization
Before generating tax lines, the system groups line items together using different criteria and generates a summation tax line for them.
Due to the new calculation of the summation tax lines, there could be rounding differences within the document. The reason is that the tax for the total of the lines is not necessarily the same as the total of the taxes on the individual lines. This balance is distributed differently, dependent on whether gross conditions are involved.
