Internal Tables in Release 7.40, SP08
2. Expressions for internal tables
Other versions:
7.31 | 7.40 | 7.54
Modification 1
Groupings
A new variant LOOP AT itab
... GROUP BY of the statement LOOP AT itab
enables the rows in an internal table to be grouped and then the groups evaluated in a
group loop. The new statement LOOP AT GROUP
for
member groups is used to access the rows in a group.
The new variants FOR
GROUPS ... OF and FOR ... IN GROUP
in an
iteration expression for
table iterations using
FOR
can be used to perform the same groupings (and evaluate them) in
table comprehensions and
table reductions as well.
The new options for grouping internal tables exist alongside the existing control level processing functions and can replace them in many cases.
