ALV Field catalog problem

Former Member — Wed, 03 Oct 2007 14:56:09 GMT

Hi All

I am doing field catalog merge for a structure using the FM

'LVC_FIELDCATALOG_MERGE' . I am passing the structure to this FM.

Initially there were 14 fields in the structure. I added a new field

and activated the structure. But it still shows only 14 fields instead of 15.

Please Reply ASAP.

Thanks.

Praveena.

Hi,


CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
EXPORTING
I_BUFFER_ACTIVE = 'X'      " Put this as X
I_STRUCTURE_NAME = 'SFLIGHT'
I_CLIENT_NEVER_DISPLAY = 'X'
I_BYPASSING_BUFFER = 'X'      " Put this as X
I_INTERNAL_TABNAME =
CHANGING
ct_fieldcat = fieldcat
EXCEPTIONS
INCONSISTENT_INTERFACE = 1
PROGRAM_ERROR = 2
OTHERS = 3.

Yes, go in debug mode.Keep a break point at K_KKB_FIELDCAT_MERGE.

This fm has following code. Keep a break point in second ALV_CHECK_BUFFER.

call function 'ALV_CHECK_BUFFER'

exporting

i_buffer_type = 'A'

i_buffer_active = i_buffer_active

i_bypassing_buffer = i_bypassing_buffer

i_refresh_buffer = ' '

importing

e_import = l_import

e_export = l_export

e_delete = l_delete.

call function 'ALV_CHECK_BUFFER'

exporting

i_buffer_type = 'B'

i_buffer_active = i_buffer_active

i_bypassing_buffer = i_bypassing_buffer

i_refresh_buffer = ' '

importing

e_import = l_import_b

e_export = l_export_b

e_delete = l_delete_b.

After the second ALV_CHECK_BUFFER executes, clear value of variable l_import_b. This will help you to see new added fields to your structure in report output.

Hi,

Use the fieldcatalog table used under changing parameter

ct_fieldcat = fieldcat

loop at fieldcat.

if fieldcat-fieldname = 'FIELDNAME'. 
fieldcat-no_OUT = 'X'.
fieldcat-tech = 'X'.
modify fieldcat.
endif.
endloop.

Thanks,

Sriram Ponna.

Hello Praveena

The ALV function group buffers the structure data. If this problem occurs simple "reboot" the transaction (enter<b> /NSE80</b> into command window, top left) and execute your program again.
