PLEASE HELP ME..

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'

EXPORTING

I_BUFFER_ACTIVE =

I_STRUCTURE_NAME = 'KNA1'

I_CLIENT_NEVER_DISPLAY = 'X'

I_BYPASSING_BUFFER =
I_INTERNAL_TABNAME = 'IKNA1'

CHANGING

CT_FIELDCAT = FIELDCAT

EXCEPTIONS

INCONSISTENT_INTERFACE = 1

PROGRAM_ERROR = 2

OTHERS = 3

IF SY-SUBRC <> 0.

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

Hi Sharath

It has to be a database table.

Otherwise dump.

HI Suhas,

hi,

check this example

data LS_FCAT type LVC_S_FCAT.

call function 'LVC_FIELDCATALOG_MERGE'

exporting

I_STRUCTURE_NAME = 'ZSUPPORTTOOL' "database structure or table name

changing

CT_FIELDCAT = GT_FIELDCAT.

loop at GT_FIELDCAT into WA_FIELDCAT.

if WA_FIELDCAT-FIELDNAME = 'MODULE'.

WA_FIELDCAT-COLTEXT = 'MODULE'.

WA_FIELDCAT-OUTPUTLEN = 6.

endif.

if WA_FIELDCAT-FIELDNAME = 'AREA'.

WA_FIELDCAT-COLTEXT = 'AREA'.

WA_FIELDCAT-OUTPUTLEN = 25.

endif.

modify GT_FIELDCAT index SY-TABIX from WA_FIELDCAT.

endloop.

Hi sharath,

u can use like this:-

DATA: ls_fcat TYPE lvc_s_fcat.

DATA: lv_pos TYPE i.

lv_pos = lv_pos + 1.

ls_fcat-fieldname = 'INSTANCE'. :(fieldname of internal table)

ls_fcat-coltext = 'Instance'.

ls_fcat-col_pos = lv_pos.

ls_fcat-outputlen = 20.

ls_fcat-no_out = 'X'.

ls_fcat-col_opt = 'X'.

APPEND ls_fcat TO pt_fcat.

CLEAR ls_fcat.

ls_fcat-edit = ' '.

lv_pos = lv_pos + 1.

ls_fcat-fieldname = 'PARENT'.

ls_fcat-coltext = 'Parent'.

ls_fcat-col_pos = lv_pos.

ls_fcat-outputlen = 20.

ls_fcat-no_out = 'X'.

ls_fcat-col_opt = 'X'.

APPEND ls_fcat TO pt_fcat.

CLEAR ls_fcat.

lv_pos = lv_pos + 1.

ls_fcat-fieldname = 'LEVEL'.

ls_fcat-coltext = 'level'.

ls_fcat-col_pos = lv_pos.

ls_fcat-outputlen = 15.

ls_fcat-col_opt = 'X'.

APPEND ls_fcat TO pt_fcat.

CLEAR ls_fcat.

lv_pos = lv_pos + 1.

ls_fcat-fieldname = 'ITEM_NO'.

ls_fcat-coltext = 'Item'.

ls_fcat-col_pos = lv_pos.

ls_fcat-outputlen = 20.

ls_fcat-col_opt = 'X'.

APPEND ls_fcat TO pt_fcat.

CLEAR ls_fcat.

Thanks & Regards,

Hi Sharath,

When use the the FM to create the field catalog the internal table should have the header line.

So if you want to use the FM create the internal table with header line otherwise

fill the fieldcat manually as Ruchi mentioned above.

Hello Sharath,

I think you can draw an analogy & try as suggested in the post for LVC_FIELDCATALOG_MERGE as well. My suggestion will be to declare your internal table with LIKE keyword.

A question: Why have you passed 'KNA1' to the I_STRUCTURE_NAME parameter any relevance?

Suhas
