Welcome to SDN.

A simple ALV code

REPORT zinfotype .

TYPE-POOLS : slis.

*Structure declaration for Infotypes for customer

TYPES : BEGIN OF ty_table,

infty TYPE infty,

pnnnn TYPE pnnnn_d,

END OF ty_table.

*Structure for infotype text

TYPES : BEGIN OF ty_itext,

infty TYPE infty,

itext TYPE intxt,

sprsl TYPE sprsl,

END OF ty_itext.

*Structure for output display

TYPES : BEGIN OF ty_output,

infty TYPE infty,

itext TYPE intxt,

pnnnn TYPE pnnnn_d,

END OF ty_output.

*internal table and work area declarations

DATA : it_table TYPE STANDARD TABLE OF ty_table INITIAL SIZE 0,

it_output TYPE STANDARD TABLE OF ty_output INITIAL SIZE 0,

it_ittext TYPE STANDARD TABLE OF ty_itext INITIAL SIZE 0,

wa_table TYPE ty_table,

wa_output TYPE ty_output,

wa_ittext TYPE ty_itext.

*Data declarations for ALV

DATA: c_ccont TYPE REF TO cl_gui_custom_container, "Custom cont

c_alvgd TYPE REF TO cl_gui_alv_grid, "ALV grid

it_fcat TYPE lvc_t_fcat, Fieldcat

INITIALIZATION.

START-OF-SELECTION.

*select the infotypes maintained

SELECT infty

pnnnn

FROM t582a

INTO TABLE it_table.

*Select the infotype texts

IF it_table[] IS NOT INITIAL.

SELECT itext

sprsl

FROM t582s

INTO CORRESPONDING FIELDS OF TABLE it_ittext

FOR ALL ENTRIES IN it_table

WHERE infty = it_table-infty

AND sprsl = 'E'.

ENDIF.

*Apppending the data to the internal table of ALV output

LOOP AT it_table INTO wa_table.

wa_output-infty = wa_table-infty.

wa_output-pnnnn = wa_table-pnnnn.

• For texts

READ TABLE it_ittext INTO wa_ittext WITH KEY infty = wa_table-infty.

APPEND wa_output TO it_output.

CLEAR wa_output.

ENDLOOP.

• Calling the ALV screen with custom container

CALL SCREEN 0600.

*On this statement double click it takes you to the screen painter SE51.Enter the attributes

*Create a Custom container and name it CC_CONT and OK code as *OK_CODE.

*Save check and Activate the screen painter.

Now a normal screen with number 600 is created which holds the ALV grid. PBO of the actual screen , Here we can give a title *and customized menus
