The log of modifications allows you to see the differences at the individual employee level from the previous month:

Select the different options then click on Preview or Print. It is possible to choose a value if you do not want to display the smallest rounding differences.

The "New amount" is for the month you have chosen and the "Original amount" is for the previous month.

If January is chosen and the previous year exists, it will compare January with the previous month of December.
