In this step, you define the rounding up/down rules for grouping the units of measure for rounding purposes.
For units of measure assigned the same rounding rule, you can optimize the rounding process using rounding profiles.
The fields, %Up or %Down, indicate the percentages from which the system is to automatically round up or down to a complete logistics unit.
For a percentage of 100 for %up or 0 for %down, the system does not round either up or down. A percentage of 0 for %up or 100 for %down, means that the system is always to round up/down to a multiple of the assigned logistics unit of measure.
