ALV with Classes and methods

Former Member — Fri, 28 Apr 2006 05:04:22 GMT

Hi All,

Please give the solution for ALV with classes.

Here this code is used for total fields.

Bu ti need only for a group of fields.

Let assume 5 fields.

Please give the solution how to do this i.e for 5 required fields display.

Here i tried by taking gi_bseg with my selected fields.

But it is giving error that i_structure name is not mapping.

TABLES: BSEG.

**----

* G L O B A L I N T E R N A L T A B L E S

**----

DATA: gi_bseg TYPE STANDARD TABLE OF BSEG.

**----

* G L O B A L D A T A

**----

DATA: ok_code LIKE sy-ucomm,

g_wa_bseg LIKE GI_bseg.

Declare reference variables to the ALV grid and the container

DATA:

go_grid TYPE REF TO cl_gui_alv_grid,

go_custom_container TYPE REF TO cl_gui_custom_container.

**----

* S T A R T - O F - S E L E C T I O N.

START-OF-SELECTION.

SET SCREEN '10'.

MODULE user_command_0010 INPUT.

CASE ok_code.

WHEN 'EXIT'.

LEAVE TO SCREEN 0.

ENDCASE.

ENDMODULE. " USER_COMMAND_0100 INPUT

MODULE status_0010 OUTPUT.

* Create objects

IF go_custom_container IS INITIAL.

CREATE OBJECT go_custom_container

EXPORTING container_name = 'ALV_CONTAINER'.

CREATE OBJECT go_grid

EXPORTING

i_parent = go_custom_container.

PERFORM load_data_into_grid.

ENDIF.

ENDMODULE. " STATUS_0100 OUTPUT

&----

*& Form load_data_into_grid

&----

FORM load_data_into_grid.

* Read data from table SFLIGHT

SELECT *

FROM BSEG

INTO TABLE gi_bseg.

* Load data into the grid and display them

CALL METHOD go_grid->set_table_for_first_display

EXPORTING i_structure_name = 'BSEG'

CHANGING it_outtab = GI_bseg.

ENDFORM. " load_data_into_grid

I guess the reason is BSEG is a cluster table, because of which its throwing the error.

Hi prashanth,

build your fieldcatalogue using LVC_FIELDCATALOG_MERGE

and use the fieldcat to display the table when you call the display method..

Hi Ravi

It is working when i take

DATA: gi_bseg TYPE STANDARD TABLE OF BSEG.

But when i select some fields like

data : begin of gi_bseg occurs 0,

budat like bseg-budat,

wrbtr like bseg-wrbtr,

end of gi_bseg.

it is giving the error.

HI Prashanth,

create a structure with the fields you want in se11 and then use it in your program..

Hi Prashanth,

If it raises an error when you try to select only a few fields, you could use a crude apporach wherein you collect all data into an internal table. Then transfer all the fileds that you require into a second internal table. Use this table for ALV.

Hi Prashanth,

Try to Build your fieldcat manually and pass it , instead of doing that...

then you can able to see the ALV grid Output.

try manually fieldcat for the fields which you want.
