What's the 'DESCRIBE TABLE' limit?

As subject. Because when i used background job, the 'describe table' will not work. But in foreground it's wrok, why? Please help, thanks a lot.

replace this field symbol.

Without the specification of an addition, the statement DESCRIBE TABLE only sets the system fields <b>sy-tfill and sy-tleng.</b>

Thanks for your answers. But still not work in background job. My version is ECC 6.0, I don't know it's version problems or others. Very strange.

replace the describe statement with <b>lines( arg )</b> <b>arg</b> is u r internal table name.

Hi Nicole,

In ECC 6.0, you need to add IN BYTE MODE or IN CHARACTER MODE as follows :-

        DATA:  FLD(8),
            LEN TYPE I, 
*    DESCRIBE FIELD FLD LENGTH LEN. " This wont work
     DESCRIBE FIELD FLD LENGTH LEN IN CHARACTER MODE.

Thanks for your answer. But my requirement is to count internal table records. Before ECC 6.0 the 'DESCRIBE TABLE itab LINES line is OK in the foreground or background. But in the ECC 6.0 background is not work.

Actually, I can calculating internal table records by others way. I am jsut feel strange that why 'DESCRIBE TABLE' not work in the background.

Please try with this:

DATA: L_LEN TYPE I.

DESCRIBE TABLE ITAB LINES L_LEN.
WRITE: 'Total Lines', L_LEN.

Hi Nicole,

Have you try below code?

gv_record = LINES( gt_balamt[] ).

IF gv_record IS INITIAL.

MESSAGE s007 WITH text-m01. "No data found.

LEAVE LIST-PROCESSING.

DATA: lv_line TYPE I.
DATA:BEGIN OF IT_DUMMY OCCURS 0,

IT_DUMMY-DUMMY = 'one'.
append IT_DUMMY.
IT_DUMMY-DUMMY = 'two'.
