No data display

[Former Member]

Hi Abap experts,

Nothing was display when I loop the INTERNAL_TABLE.

Need your help to debug this program :-

REPORT ZUNIX1 .

data: unix_command(50) type c value 'ls -ls /usr/sap/trans/data'.

data: begin of internal_table occurs 0,

line(200),

end of internal_table.

call 'SYSTEM' id 'COMMAND' field unix_command

id 'TAB' field internal_table.

LOOP AT INTERNAL_TABLE.

WRITE:/ INTERNAL_TABLE.

ENDLOOP.

Thanks for your help.

Check this one:

data: unix_command(50) type c value 'ls -ls /usr/sap/trans/data'.

data: begin of internal_table occurs 0,

line(200),

end of internal_table.

call 'SYSTEM' id 'COMMAND' field unix_command

id 'TAB' field internal_table.

LOOP AT INTERNAL_TABLE.

WRITE:/ INTERNAL_TABLE-line.

ENDLOOP.

Regards.

Use the command as it follows:

CALL 'SYSTEM' ID 'COMMAND' FIELD unix_command
              ID 'TAB'     FIELD internal_table-*SYS*.

When you write, do:

LOOP AT internal_table.
  WRITE:/ internal_table-line.
ENDLOOP.

Hope it helps.

Regards.

hHi Ashutosh,

i think u must write

CALL 'SYSTEM' ID 'COMMAND' FIELD unix_command

ID 'TAB' FIELD internal_table-SYS.

i think u forgot to write sys may be this may be the problem.

thanks & regards
