Hi,

Use the Field Symbols for thisone, pass the value which you want to sort the Internal table, then use this Filed-Symbol to srot the Internal table

Hi,

Please try this.

DATA: BEGIN OF ITAB OCCURS 0,

F1(4),

END OF ITAB.

DATA: BEGIN OF ITAB2 OCCURS 0,

F1(1),

F2(1),

F3(4),

END OF ITAB2.

ITAB-F1 = '01AC'.

APPEND ITAB.

ITAB-F1 = '02AB'.

APPEND ITAB.

ITAB-F1 = '01CD'.

APPEND ITAB.

ITAB-F1 = '02CA'.

APPEND ITAB.

LOOP AT ITAB.

ITAB2-F1 = ITAB-F1+2(1).

ITAB2-F2 = ITAB-F1+3(1).

ITAB2-F3 = ITAB-F1.

APPEND ITAB2.

ENDLOOP.

SORT ITAB2 BY F1 ASCENDING

F2 DESCENDING.

LOOP AT ITAB2.

WRITE: / ITAB2-F3.

ENDLOOP.

Hi

U can use a number of max fields for sorting:

DATA: FIELD1(30),

FIELD2(30),

FIELD3(30).

SORT ITAB BY (FIELD1) (FIELD2) (FIELD3).

Max

Hello Neelesh,

I think sorting is not possible by using field symbols, it can be used to modify table contents. This is because field symbol will just point to a line of the table.

Anyways as far as your requirement is concerned if you want your table to be sorted in order of its key fields just use the statement.

<b> SORT <itab> [ASCENDING|DESCENDING] </b>

Variable number of fields will not cause any problem in this.

But if you want table to sorted by a different key, you can specify the key in the SORT statement. There you need to know field names (either static or dynamically) .

<b>

SORT <itab> [ASCENDING|DESCENDING]

BY <f1> [ASCENDING|DESCENDING]

...

<fn> [ASCENDING|DESCENDING]</b>

f1, f2, ........fn are the fields according to which you want to sort. It can be harcoded or set dynamically.

Award points if useful.

HI,

you have to put your fields in an i_tab then use

sort tablename by ( i_tab ).

Here is an example:

PARAMETERS dbtab TYPE c LENGTH 30.

SELECT-OPTIONS columns FOR dbtab NO INTERVALS.

DATA: otab TYPE abap_sortorder_tab,

oline TYPE abap_sortorder,

dref TYPE REF TO data.

FIELD-SYMBOLS: <column> LIKE LINE OF columns,

<itab> TYPE STANDARD TABLE.

TRY.

CREATE DATA dref TYPE STANDARD TABLE OF (dbtab).

ASSIGN dref->* TO <itab>.

CATCH cx_sy_create_data_error.

MESSAGE 'Wrong data type!' TYPE 'I' DISPLAY LIKE 'E'.

LEAVE PROGRAM.

ENDTRY.

TRY.

SELECT *

FROM (dbtab)

INTO TABLE <itab>.

CATCH cx_sy_dynamic_osql_semantics.

MESSAGE 'Wrong database table!' TYPE 'I' DISPLAY LIKE 'E'.

LEAVE PROGRAM.

ENDTRY.

LOOP AT columns ASSIGNING <column>.

oline-name = <column>-low.

APPEND oline TO otab.

ENDLOOP.

TRY.

SORT <itab> BY (otab).

CATCH cx_sy_dyn_table_ill_comp_val.

MESSAGE 'Wrong column name!' TYPE 'I' DISPLAY LIKE 'E'.

LEAVE PROGRAM.

ENDTRY.

Sooness.
