Sorting Internal Tables in ABAP
Sorting Internal Tables
You can sort a standard or hashed table in a program. To sort a table by its key, use the statement
SORT <itab> [ASCENDING|DESCENDING] [AS TEXT] [STABLE].
The statement sorts the internal table <itab> in ascending order by its key. The statement always applies to the table itself, not to the header line. The sort order depends on the sequence of the standard key fields in the internal table. The default key is made up of the non-numeric fields of the table line in the order in which they occur.
You can specify the direction of the sort using the additions ASCENDING and DESCENDING. The default is ascending.
The larger the sort key, the more time the system needs to sort the table. If the sort key contains an internal table, the sorting process may be slowed down considerably.
