how to extract o/p data from list _to_asci and put inside my current internal table?

Hi Gurus,

I have a problem can anyone share ideas

I have fetched output data from RFITEMAR by using list_from_memory and list_to_asci and now the out put is present in internal table "writes" and this is in string format my problem is how to fetch those data and put in my internal table.

my sample code is as below

DATA: listobj LIKE abaplist OCCURS 0 WITH HEADER LINE.

DATA: writes LIKE listzeile OCCURS 0 WITH HEADER LINE.

TYPES: BEGIN OF st_out,

END OF

START-OF-SELECTION.

SUBMIT rfitemar

EXPORTING LIST TO MEMORY AND RETURN.

REFRESH listobj.

CALL FUNCTION 'LIST_FROM_MEMORY'

TABLES

listobject = listobj

EXCEPTIONS

not_found = 1.

IF sy-subrc <> 0.

ENDIF.

REFRESH writes.

CALL FUNCTION 'LIST_TO_ASCI'

TABLES

listasci = writes

listobject = listobj

EXCEPTIONS

empty_list = 1.

IF sy-subrc <> 0.

WRITE: / 'LIST_TO_ASCI error'(098).

ENDIF.

data:g_tabix type n.

IF writes IS NOT INITIAL. "i have to delete 1-11 lines from internal table"

DELETE writes INDEX 1.

DELETE writes INDEX 1.

DELETE writes INDEX 1.

DESCRIBE TABLE writes LINES g_tabix.

ENDIF.
