U should use the index in order to read or delete a certain record:



N = 10.
* Reading
DO   N    TIMES.
  READ TABLE INTAB INDEX N.
  IF SY-SUBRC = 0.
    WRITE: / 'Read record nr.:', SY-INDEX.
  ENDIF.
ENDDO.

N = 11.
* Deleting (all records from 11th)
DO .
 DELETE ITAB INDEX N.
 IF SY-SUBRC <> 0. EXIT. ENDIF.
ENDDO.

check this code

TYPES : BEGIN OF ty_itab,
       a TYPE i,
       b TYPE i,
       END OF ty_itab.

DATA : wa_itab TYPE ty_itab,
       it_itab TYPE TABLE OF ty_itab.


DO 25 TIMES.

  wa_itab-a = sy-index.
  wa_itab-b = sy-index + 1.
  APPEND wa_itab TO it_itab.

ENDDO.

LOOP AT it_itab INTO wa_itab.
  READ TABLE it_itab INTO wa_itab INDEX sy-tabix.
  WRITE : / wa_itab-a , wa_itab-b.
  IF sy-tabix GE 10.
    DELETE itab INDEX sy-tabix.
  ENDIF.
ENDLOOP.

With Regards.
