[Former Member]

I am displaying data through ALV using SET_TABLE_FOR_FIRST_DISPLAY method of class CL_GUI_ALV_GRID.

is there any function module available to create the field catalog for that??

the F.M. "REUSE_ALV_FIELDCATALOG_MERGE" is giving some error for that. any other function moudle is available or not??

how to use above function module for that??

Hi ,

Use can use FM 'REUSE_ALV_FIELDCATALOG_MERGE' for fieldcatolgue display .

try to pass by creating a structure .for ex..

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

I_PROGRAM_NAME = g_repid

I_INTERNAL_TABNAME = 'HEADER'

I_STRUCTURE_NAME = 'Z9I_STK_LISTE1_H'

CHANGING

CT_FIELDCAT = lt_fcat.

Hi,

There are many ways in which to build a field catalog, some of which can be found below:

Building a fieldcatalog based on a dictionary structure/table

• This Method requires you to create a dictionary structure via

• SE11 and pass that in the 'I_STRUCTURE_NAME' parameter.

• The below example will be for all of EKKO but you could create a new

• structure containing only the fields you require.

*For Function module ALV (report)

DATA: it_fieldcat TYPE slis_t_fieldcat_alv,

wa_fieldcat LIKE LINE OF it_fieldcat.

CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'

EXPORTING

i_structure_name = 'EKKO'

CHANGING

ct_fieldcat = it_fieldcat

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.

*For object ALV (Screen)

DATA: gd_fieldcat2 type LVC_T_FCAT.

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING

I_BUFFER_ACTIVE =

I_STRUCTURE_NAME = 'EKKO'

I_CLIENT_NEVER_DISPLAY = 'X

I_BYPASSING_BUFFER =

CHANGING

ct_fieldcat = gd_fieldcat2

EXCEPTIONS

INCONSISTENT_INTERFACE = 1

PROGRAM_ERROR = 2

OTHERS = 3.
