<ZH>Example:</> The row definition of a report contains a
multi-dimension set with the characteristics Cost Center and Account.
The rows with the total for all accounts (level 1 of the
characteristic Account) are identical with the rows for the totals at
cost center level (level 1- of the characteristic Cost Center). The
Report Writer always assigns these rows, that correspond to the group
change, to level 1- of the higher-level characteristic; in this example,
the cost centers. Level 1 of the lower-level characteristic must not
therefore be used.
<ZH>Note:</> You can also enter hierarchy levels in the pop-up window
'Additional Totals Display'.
