Hi,

Just checked out with a demo program, alv data cannot be obtained from LIST_FROM_MEMORY simply because ALV will be calling a seperate screen rather than the screen called for list printing.

ex:

REPORT zzalvcallsubmit .

FIELD-SYMBOLS : <fs> TYPE ANY.

DATA : l_string TYPE string VALUE '(ZZALV)P_SIMPLE'.

DATA : t_select TYPE rsparams OCCURS 0 WITH HEADER LINE.

t_select-selname = 'S_DATE'.

t_select-sign = 'I'.

t_select-option = 'BT'.

t_select-low = '20040101'.

t_select-high = '20051231'.

APPEND t_select.

SUBMIT zzalv WITH SELECTION-TABLE

t_select EXPORTING LIST TO MEMORY AND RETURN.

DATA : t_list TYPE abaplist OCCURS 0 WITH HEADER LINE.

CALL FUNCTION 'LIST_FROM_MEMORY'

TABLES

listobject = t_list

EXCEPTIONS
NOT_FOUND = 1
OTHERS = 2

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

Hi rani,

1. if its an ALV LIST (and not grid)

then we can get the data.

2. moreover,

the data will be raw data.

We will not be able to extract information

from it.

3. It will be exactly in the same format

as it is printed,

(ie. with headings, vertical lines, etc)

regards,

amit m.

            OTHERS     = 2.

  IF SY-SUBRC = 0.
    CALL FUNCTION 'LIST_TO_ASCI'
         TABLES
              LISTASCI           = IT_ASC
              LISTOBJECT         = IT_LIST
         EXCEPTIONS
              EMPTY_LIST         = 1
              LIST_INDEX_INVALID = 2
              OTHERS             = 3.
  ENDIF.
