alv function modules

Former Member — Tue, 25 Mar 2008 06:29:51 GMT

Hi,

can anybody explain when we can use the following function modules.

REUSE_ALV_VARIANT_F4,

REUSE_ALV_VARIANT_DEFAULT_GET.

Re: alv function modules

Former Member — Tue, 25 Mar 2008 06:35:51 GMT

REUSE_ALV_VARIANT_F4 is used to display the variant selection dialog box from which u can select the variant u want.

REUSE_ALV_VARIANT_DEFAULT_GET is ti read the default variant.

Thanks

Hi,

REUSE_ALV_VARIANT_F4

Possible entries help, if the variant is defined explicitly as an input field on a screen. The selection must be specified by at least partially filling the parameter structure IS_VARIANT.

REUSE_ALV_VARIANT_DEFAULT_GET

Provides the default variant for the list specified in the structure parameter CS_VARIANT of a program.

Parameters

I_SAVE

CS_VARIANT

Thanks,

Suman

HI,

Text :Display variant selection dialog box

Functionality

Possible entries help, if the variant is defined explicitly as an input field on a screen. The selection must be specified by at least partially filling the parameter structure IS_VARIANT.

Go through the following program, you can get the where exactly it is used.

Hi,

'REUSE_ALV_VARIANT_F4' is used to find out the variants that are already maintained for that report . it is on

at selection-screen like ....

at selection-screen on value-request for p_var.

wa_variant1-report = sy-repid.

call function at selection-screen on value-request for p_var.

wa_variant1-report = sy-repid.

call function 'REUSE_ALV_VARIANT_F4'

exporting

is_variant = wa_variant1

I_TABNAME_HEADER =
I_TABNAME_ITEM =
IT_DEFAULT_FIELDCAT =

i_save = 'A'

i_display_via_grid = 'X'

importing

e_exit = v_exit

es_variant = wa_variant2

exceptions

not_found = 1

program_error = 2

others = 3

if sy-subrc = 0.

p_var = wa_variant2-variant.

else.

clear wa_variant2.

endif.

and 'REUSE_ALV_VARIANT_DEFAULT_GET' comes in the initialization part to provide a default layout of that report on selection screen.

wa_variant2-report = sy-repid.

call function 'REUSE_ALV_VARIANT_DEFAULT_GET'

exporting

i_save = 'A'

changing

cs_variant = wa_variant2

exceptions

wrong_input = 1

not_found = 2

program_error = 3

others = 4.

if sy-subrc = 0.

p_var = wa_variant2-variant.

else.

p_var = '/DEFAULT'.

endif.

'REUSE_ALV_VARIANT_DEFAULT_GET':

Those variants are different which we can declare in the Selection screen, where as in ALV's report you have to handle the Variants by using FM 'REUSE_ALV_VARIANT_DEFAULT_GET', because in the runtime these variants will be passed to the field catalog. that is the reason you needs to use this FM in ALV's for passing an variant.

Hi,

REUSE_ALV_VARIANT_F4

Display variant selection dialog box

Possible entries help, if the variant is defined explicitly as an input field on a screen. The selection must be specified by at least partially filling the parameter structure IS_VARIANT.

Go thru in this..

DATA: VAR TYPE DISVARIANT.

PARAMETERS: P_VARI LIKE DISVARIANT-VARIANT.

INITIALIZATION.

VAR-REPORT = SY-REPID.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VARI.

CALL FUNCTION 'REUSE_ALV_VARIANT_F4'

EXPORTING

IS_VARIANT = VAR

IMPORTING

ES_VARIANT = VAR.

P_VARI = VAR-VARIANT.

call function 'REUSE_ALV_GRID_DISPLAY'

exporting

i_callback_program = sy-repid

is_layout = gd_layout

it_fieldcat = fieldcatalog[]

i_save = 'X'

is_variant = VAR

tables

t_outtab = it_ekko

Reward Points if found helpfull..
