Hi,

1) Build the field catalog.

2) Set up the layout (Not mandatory).

3) Have the data for display.

Check this simple ALV program.

TYPE-POOLS: slis.

Data declaration.

DATA: BEGIN OF itab OCCURS 0,

vbeln TYPE vbeln,

erdat TYPE erdat,

auart TYPE auart,

netwr TYPE vbak-netwr,

END OF itab.

DATA: wa_kna1 TYPE kna1.

DATA: t_fieldcatalog TYPE slis_t_fieldcat_alv.

DATA: s_fieldcatalog TYPE slis_fieldcat_alv.

Selection-screen.

PARAMETERS: p_kunnr TYPE kunnr OBLIGATORY.

AT SELECTION-SCREEN.

SELECT SINGLE * FROM kna1 INTO wa_kna1

WHERE kunnr = p_kunnr.

IF sy-subrc <> 0.

MESSAGE s208(00) WITH 'Invalid customer'.

LEAVE LIST-PROCESSING.

ENDIF.

START-OF-SELECTION.

Building the field catalog.

s_fieldcatalog-col_pos = '1'.

s_fieldcatalog-fieldname = 'VBELN'.

s_fieldcatalog-tabname = 'ITAB'.

s_fieldcatalog-rollname = 'VBELN'.

s_fieldcatalog-outputlen = '12'.

APPEND s_fieldcatalog TO t_fieldcatalog.

CLEAR: s_fieldcatalog.

s_fieldcatalog-col_pos = '2'.

s_fieldcatalog-fieldname = 'ERDAT'.

s_fieldcatalog-tabname = 'ITAB'.

s_fieldcatalog-rollname = 'ERDAT'.

APPEND s_fieldcatalog TO t_fieldcatalog.

CLEAR: s_fieldcatalog.

s_fieldcatalog-col_pos = '3'.

s_fieldcatalog-fieldname = 'AUART'.

s_fieldcatalog-tabname = 'ITAB'.

s_fieldcatalog-rollname = 'AUART'.

APPEND s_fieldcatalog TO t_fieldcatalog.

CLEAR: s_fieldcatalog.

s_fieldcatalog-col_pos = '4'.

s_fieldcatalog-fieldname = 'NETWR'.

s_fieldcatalog-tabname = 'ITAB'.

s_fieldcatalog-rollname = 'NETWR_AK'.

s_fieldcatalog-do_sum = 'X'.

APPEND s_fieldcatalog TO t_fieldcatalog.

CLEAR: s_fieldcatalog.

Get the sales orders.

SELECT vbeln erdat auart netwr

FROM

vbak

INTO TABLE itab

WHERE kunnr = p_kunnr.

IF sy-subrc <> 0.

MESSAGE s208(00) WITH 'No records found'.

LEAVE LIST-PROCESSING.

ENDIF.

DATA: v_repid TYPE syrepid.

v_repid = sy-repid.

Events

DATA: t_events TYPE slis_t_event,

s_events LIKE LINE OF t_events.

s_events-name = 'TOP_OF_PAGE'.

s_events-form = 'TOP_OF_PAGE'.

APPEND s_events TO t_events.

Display the alv

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

i_callback_program = v_repid

it_fieldcat = t_fieldcatalog

it_events = t_events[]

TABLES

t_outtab = itab.

Hi Sunil,

Programming Steps:

Declare data areas for list viewer

Declare internal table to store selected data

Select data into internal table

Build field catalog

Build sort catalog

Build event catalog

Start list viewer

STEP 1:

Specifying a field Catalogue

Specify a heading for a report.

Type lvc_title

Create a field catalogue for the report

Table of type slis_t_fieldcat_alv

line_fieldcat-fieldname : Field name

line_fieldcat-tabname : Itab name

line_fieldcat-key : Specifies key

line_fieldcat-seltext_m : Coloumn header

line_fieldcat-hotspot : Indicate hotspot

line_fieldcat-checkbox : Display checkbox

line_fieldcat-edit : Allow editing

STEP 2:

Choosing and saving Layouts

Save options

' ' = No display variants can be saved

'X' = Standard display variants can be saved

'U’ = User-specific display variants can be saved

'A' = Standard & user-specific can be saved

Layout options

Structure type slis_layout_alv

i_layout-colwidth_optimize = 'X' : Opt col width

i_layout-zebra = ‘X’ : Alt color pattern

i_layout-no_vline = ‘X” : No vertical line

STEP 3:

A Simple ALV Program

Using REUSE_ALV_GRID_DISPLAY

Passing minimum parameter

Data to be displayed

Format of Column ( Field Catalogue )

Let ALV set standard PF_status

STEP 4:

Initialize Events

Initialize events

Type slis_t_event

Use event 'TOP_OF_PAGE' to write a header

Type slis_t_listheader

REUSE_ALV_COMMENTARY_WRITE

ALV supports 16 events

Hope this will help.

Regards,

Ferry Lianto

Hi Sunil,

The best way to learn about ALV and specially ALV using Objects is by studying the standard SAP programs. Type BCALV_GRID_* in reports transaction, you will get a list of 10 programs...with step by step explainations given.

Hope this helps.

Thanks,

Following are the steps for creating ALV reports.

1. Fill the data which you want to display in the ALV report in asingle internal table.

2. Prepare the fieldcatalog for the fields.

3. Prepare the event catalog list.

4. Call function "REUSE_ALV_GRID_DISPLAY" for displaying the grid display

and pass the appropiate parameters.
