ALV OOPs

Hi,

see this example

DATA:t_mara TYPE TABLE OF mara.

DATA:FCAT TYPE LVC_T_FCAT.

DATA:G_CONTAINER TYPE SCRFNAME VALUE 'TABC',"TABC is *container in screen 101

GRID TYPE REF TO CL_GUI_ALV_GRID,

G_CUSTOM_CONTAINER TYPE REF TO CL_GUI_CUSTOM_CONTAINER.

set screen 101.

MODULE STATUS_0101 output.

IF G_CUSTOM_CONTAINER IS INITIAL.

CREATE OBJECT G_CUSTOM_CONTAINER "CREATING OBJECT FOR CUSTOM CONTAINER

EXPORTING CONTAINER_NAME = G_CONTAINER.

CREATE OBJECT GRID "CREATING GRID IN WRKBNCH SCREEN

EXPORTING I_PARENT = G_CUSTOM_CONTAINER.

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING

I_STRUCTURE_NAME = 'MARA'

CHANGING

CT_FIELDCAT = FCAT[].

SELECT * from mara into table t_mara.

CALL METHOD GRID->SET_TABLE_FOR_FIRST_DISPLAY

CHANGING

IT_FIELDCATALOG = FCAT[]

IT_OUTTAB = t_MARA.

ENDIF.

ENDMODULE.

flow logic of screen 101:

PROCESS BEFORE OUTPUT.

MODULE STATUS_0101.

PROCESS AFTER INPUT.

Hi,

Check this..

DATA ls_fldcat TYPE lvc_s_fcat.

Hi Naseer,

you can try this

DATA : TABNAME TYPE DD02L-TABNAME,

fcat type table of LVC_T_FCAT.

TABNAME = 'ITAB'.

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING

• I_BUFFER_ACTIVE =

I_STRUCTURE_NAME = TABNAME

• I_CLIENT_NEVER_DISPLAY = 'X'

• I_BYPASSING_BUFFER =

I_INTERNAL_TABNAME = TABNAME

CHANGING

ct_fieldcat = fcat

EXCEPTIONS

INCONSISTENT_INTERFACE = 1

PROGRAM_ERROR = 2

OTHERS = 3

.

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.
