Choose Layout option in the selection screen

[Former Member]

Hai Friends,

I am displaying my report in ALV. I want to give a Layout option in the selection screen as in FAGLL03. How can i do this?.

Add the display variant as a parameter on the selection screen.and then call FM REUSE_ALV_VARIANT_F4 when the user presses F4 for the variant.

HI,

Firt create a parameter as shown below and then use a FM to get the values of the variants

DATA  G_VARIANT      LIKE DISVARIANT.
PARAMETERS P_VAR LIKE DISVARIANT-VARIANT.

INITIALIZATION.
G_VARIANT-REPORT = SY-REPID.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VAR.
  CALL FUNCTION 'REUSE_ALV_VARIANT_F4'
    EXPORTING
      IS_VARIANT                = G_VARIANT
     I_SAVE                    = 'A'
 IMPORTING
   ES_VARIANT                = G_VARIANT
 EXCEPTIONS
   NOT_FOUND                 = 1
   PROGRAM_ERROR             = 2
   OTHERS                    = 3
            .
  IF SY-SUBRC = 0.
    P_VAR = G_VARIANT-VARIANT.
  ELSE.
    MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
In your FM REUSE_ALV_GRID_DISPLAY, pass G_VARIANT to the parameter IS_VARIANT of the FM.

Hope this helps.

Steps are as follows :

1. On selection screen create the parameter :

SELECTION-SCREEN BEGIN OF BLOCK blk3 WITH FRAME TITLE text-021.

*-- Parameters for ALV display

PARAMETERS: p_layout TYPE variant.

SELECTION-SCREEN END OF BLOCK blk3.

2. Attach F4 help to this parameter using FM

CALL FUNCTION 'REUSE_ALV_VARIANT_F4'

EXPORTING

is_variant = gw_alv_variant

i_save = 'A'

IMPORTING

es_variant = gw_alv_variant

EXCEPTIONS

not_found = 1

program_error = 2

OTHERS = 3.

3. Set this layout for initial display of ALV . Otherwise there is no meaning to use the layout option.

*-- Set Layout

CALL METHOD go_layout->set_initial_layout

EXPORTING

value = p_layout .

Hope it helps you.
