Change layout in ALV

[Former Member]

Hi all..

I got this table contain 5 field. All these fields are output in the ALV.

How can i hide default 2 field instead on screen load. Only display the neccessary 3 field out. But when the user click on the change layout button, he can choose whatever field to be display as he like.

How can i achieve it?

Hi,

use this logic.

data: variant type disvariant.

start-of-selection.

variant-report = sy-repid.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = sy_repid

it_fieldcat = ist_fcat[]

i_save = 'X'

is_variant = variant

TABLES

t_outtab = ist_main[]

EXCEPTIONS

program_error = 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,

USe the following code

fill the defaule variant tab as below with required fields as below.

FORM check_fieldcat_variant_l.

DATA h_fieldcat_wa TYPE slis_fieldcat_alv.

DATA h_index LIKE sy-tabix.

h_index = 1.

DESCRIBE TABLE g_selfields_tab LINES sy-tabix.

IF sy-tabix IS INITIAL.

LOOP AT g_fieldcat_tab INTO h_fieldcat_wa.

CASE h_fieldcat_wa-fieldname.

WHEN 'PM_SELECTED'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 1.

WHEN 'Z_RSLID'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 2.

WHEN 'Z_FUNLC'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 3.

WHEN 'Z_SMPDS'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 4.

WHEN 'Z_SCHDT'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 5.

WHEN 'Z_SCHTM'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 6.

WHEN 'Z_ANLYT'.

h_fieldcat_wa-no_out = space.

h_fieldcat_wa-col_pos = 7.

WHEN OTHERS.

h_fieldcat_wa-no_out = g_x.

ENDCASE.

MODIFY g_fieldcat_tab FROM h_fieldcat_wa.

ENDLOOP.

ENDIF.

ENDFORM. " CHECK_FIELDCAT_VARIANT_L

and pass the that intrnal table in the following FM

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

Hi,

You can do as below :

While building your fieldcatalog for all the fields, for that fields that should be in change layout for that fields you can use the code as gs_fieldcat-no_out = 'X'.

if i code gs_fieldcat-no_out = 'X', will it affect the user when he want to display that field when he click on the change layout button and choose that field to be shown. Will the field still be shown or not shown?

Thx i tested it worked.

Hi,

Due to this code, I field will be in the change layout, once the report is displayed you can choose the other fields by selecting change layout, if yuo select those fields in the change layout, that fields will be displayed in the repoer.

Thanks,

Sriram Ponna.
