A requirement for the correct determination of rounding differences is that validating the rounding rules in local currency does not result in any differences. This validation is performed before calculating the rounding differences in group currency. If differences in local currency occur, an error message is output. In this case, the rounding entry is defined incorrectly.When multiple checks for rounding differences are run, the sequence of the rounding entries might be important so that a later rounding assignment does not destroy a range of items that was processed before.
