yes, it can be done. Here is the code for reference if you are using FM -

REPORT  ZSKC_TEST.
TYPE-POOLS : SLIS.
DATA : I_MARA TYPE TABLE OF MARA.

START-OF-SELECTION.

SELECT * UP TO 10 ROWS
FROM   MARA
INTO   TABLE I_MARA
WHERE  MATNR NE SPACE.

CHECK SY-SUBRC EQ 0.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
  EXPORTING
    I_CALLBACK_PROGRAM                = 'ZSKC_TEST'
    I_CALLBACK_USER_COMMAND           = 'SUB_CALL_BACK'
    I_STRUCTURE_NAME                  = 'MARA'
  TABLES
    T_OUTTAB                          = I_MARA
  EXCEPTIONS
    PROGRAM_ERROR                     = 1
    OTHERS                            = 2.


*&---------------------------------------------------------------------*
*&      Form  SUB_CALL_BACK
*&---------------------------------------------------------------------*
*      CALL BACK ROUTINE FOR ALV
*----------------------------------------------------------------------*
FORM SUB_CALL_BACK USING I_FCODE     TYPE sy-ucomm
                         IS_selfield TYPE slis_selfield.
FIELD-SYMBOLS : <FS_MARA> TYPE MARA.

  LOOP AT I_MARA ASSIGNING <FS_MARA>.
    <FS_MARA>-ERNAM = SY-UNAME.
  ENDLOOP.
  IS_SELFIELD-REFRESH = 'X'.

ENDFORM.                    " SUB_CALL_BACK

Refer the below code :

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

I_CALLBACK_USER_COMMAND = 'USER_COMMAND'

IT_FIELDCAT = GT_FIELDCAT

IS_LAYOUT = GS_LAYOUT

TABLES

T_OUTTAB = IT_FINAL.

FORM USER_COMMAND USING LV_UCOMM TYPE SYUCOMM

LS_SELFIELD TYPE SLIS_SELFIELD. "#EC CALLED

process fcodes relevant for application

CASE LV_UCOMM.

refresh list

WHEN 'REFRESH'.

PERFORM ALV_DISPLAY.

ENDCASE.

FORM ALV_DISPLAY.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

IT_FIELDCAT = GT_FIELDCAT1

IS_LAYOUT = GS_LAYOUT1

TABLES

T_OUTTAB = IT_FINAL1.

ENDFORM.

Hi,

for your requirement i.e you can change the internal table data after displaying by using edit functionality

in the alv

please check the following code

{

LOOP AT IT_FIELDCAT INTO WA_FIELDCAT .

CASE: WA_FIELDCAT-FIELDNAME.

WHEN 'MATNR'.

WA_FIELDCAT-NO_OUT = ' '.

WHEN 'MEINS'.

WA_FIELDCAT-NO_OUT = ' '.

WHEN 'MTART'.

WA_FIELDCAT-NO_OUT = ' '.

WA_FIELDCAT-EDIT = 'X'.

WHEN 'MBRSH'.

WA_FIELDCAT-NO_OUT = ' '.

WHEN OTHERS.

WA_FIELDCAT-NO_OUT = 'X'.

ENDCASE.

MODIFY IT_FIELDCAT FROM WA_FIELDCAT.

ENDLOOP.

}

Thnaks & Regards,

Sateesh
