ABAP SORT ITAB OBSOLETE Statement syntax, information and example SAP source code

SORT itab BY field_symbol

ABAP Syntax(Obsolete) SORT itab BY
fs1 fs2 ...

What does it do? In internal tables with
header lines , field symbols can also be specified as a sort criterion for comp1 comp2 ... after SORT ... BY
. If a component of the header line or the whole header line is assigned to the field symbol when the statement is executed, the table is sorted by the corresponding component or the whole line. If no data object is assigned to a field symbol, the specification is ignored. If a different data object is assigned to a field symbol, an untreatable exception is triggered.
Latest notes: Instead of using field symbols for dynamic component specifications, we recommend that you specify parenthesized character-like data objects or an internal table, which contain the name of the components.

Bad example
name = 'ITAB-COL1'.
ASSIGN (name) TO <(><<)>fs>.

SORT itab BY fs .

Good example
name = 'COL1'.

SORT itab BY (name).
