SUM(g) is not a statement, but a field which is
automatically created and filled when g is a sub-field of an
extract dataset .
SUM(g) can only be addressed from within a
LOOP on a sorted
extract dataset.
If g is a numeric field in an extract dataset (see also
ABAP/4 number types ),
SUM(g) contains the appropriate control total at the end of a
control level (AT END OF , AT
LAST ).
