Regarding internal table

[Former Member]

Hi,

How to know number of columns in an internal table at run-time.

Hi

To find out the attributes of an internal table at runtime that were not available statically, use the statement:

DESCRIBE TABLE <itab> LINES <l> OCCURS <n> KIND <k>.

Use 'describe' command.

[anversha_s]

just do this.

DATA : BEGIN OF it_mara OCCURS 0,
matnr LIKE mara-matnr,
ersda LIKE mara-ersda,
END OF it_mara.

DATA : p(5) TYPE c.
FIELD-SYMBOLS: <fs_record> TYPE ANY.
FIELD-SYMBOLS: <fs_comp> TYPE ANY.

ASSIGN it_mara TO <fs_record>.
DO.
ASSIGN COMPONENT sy-index OF STRUCTURE <fs_record> TO <fs_comp>.
IF sy-subrc EQ 0.
p = p + 1.
ELSE.
EXIT.
ENDIF.
ENDDO.

WRITE : / p.

Hi Arun,

Hi,

you can use the Describe lines itab into a variable.

if you are in a loop and find the index of the itab you can use the sy-tabix system field.
