How to make ALV input enabled - defined from structure

[Former Member]

Hello experts,

I know how to define column input enabled from field catalog, but how to do it if I use structure for definition.

I tried something like this, but it will add a new column, not change the old one:

CLEAR wa_fcat.

MOVE 'Name1' TO wa_fcat-fieldname.

MOVE 'ZTABLE01' TO wa_fcat-REF_TABLE.

MOVE 'Column1' TO wa_fcat-REF_FIELD.

MOVE 'X' TO wa_fcat-edit.

APPEND wa_fcat TO it_fcat.

call function 'LVC_FIELDCATALOG_MERGE'

exporting

i_structure_name = 'ZTABLE01'

changing

ct_fieldcat = it_fcat

exceptions

inconsistent_interface = 1

program_error = 2

others = 3.

How to change my source code?

Thanks a lot.

Hi, plese try this one:

field-symbols: <ls_fcat> type lvc_s_fcat. " if the Fieldcatalog is from Type lvc_t_fcat.

read table it_fcat assigning <ls_fcat> with key fieldname = <your field>.

if sy-subrc is initial.

<ls_fcat>-edit = 'X'.

endif.

...
