Can any body give logic, how to use function module LVC_FIELDCATALOG_MERGE to design fieldcatalog in ALV OOPs.

Naseer.

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.

DATA lc_custom_control_name TYPE scrfname VALUE 'CC_ALV'.

*--- Creating container.

CREATE OBJECT go_container

EXPORTING

container_name = lc_custom_control_name

EXCEPTIONS

cntl_error = 0

cntl_system_error = 0

create_error = 0

lifetime_error = 0

lifetime_dynpro_dynpro_link = 0

OTHERS = 0

CREATE OBJECT go_grid

EXPORTING

i_parent = go_container

EXCEPTIONS

error_cntl_create = 0

error_cntl_init = 0

error_cntl_link = 0

error_dp_create = 0

OTHERS = 0

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING

i_structure_name = 'VBAK'

CHANGING

ct_fieldcat = gt_fldcat

EXCEPTIONS

inconsistent_interface = 0

program_error = 0

OTHERS = 0.

*-- Display ALV

CALL METHOD go_grid->set_table_for_first_display

CHANGING

it_outtab = gt_leg_details

it_fieldcatalog = gt_fldcat

EXCEPTIONS

invalid_parameter_combination = 0

program_error = 0

too_many_lines = 0

OTHERS = 0.

Reward points if useful,

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.
