ALV on F4 dont show search help "button" if ref_table is initial

[oliver_am]

Hello, all.

I need to create a custom search help by code in my ALV.

I know there are reports like
BCALV_TEST_GRID_F4_HELP
BCALV_EDIT_08

The problem is the field is a field defined in my program in my internal table (no relation with a dictionary field) and It seems that is necessary to create the field in the field catalog with the reference of a field from a dictinary table, if not the "button" of the search help is not displayed, and there is no on_f4 event triggered...

You can try by yourself, execute any of theese programs:

in a normal execution you can see the "button" to trigger the f4 event.

But, if you, by debug, remove the REF_TABLE from the field catalog... there is no button

Do you know how can I define my field to display this button to trigger the on_f4 event?

Thanks in advance.

Hello Oliver,

You need to register the fields using this method:

    lw_f4-fieldname  = 'NUCTA'.
    lw_f4-register   = 'X'.
    lw_f4-chngeafter = 'X'.
    INSERT lw_f4 INTO TABLE lt_f4.
    FREE: lw_f4.

    CALL METHOD go_grid->register_f4_for_fields
      EXPORTING
        it_f4 = lt_f4.

Register the onF4 event into your ALV and implement your search help there.

BCALV_TEST_GRID_F4_HELP its a great example.

Best regards.

Hi, Eduardo.

Yes, I know it.
I was testing with this report, and this register is done. But, as I said, if the field in the fieldcatalog dont have any value in the field REF_TABLE the "button" for the search help is not visible.

No problem for me. You can display values without REF_TABLE.

Hi Sandra.

It's strange, Report BCALV_EDIT_08 if I remove this value by debug is not working:

We have an old SAP version, SAP_ABAP 701 .

Weird. No issue at my side, with SAP GUI 7.70, ABAP 7.52 SP0:

So, you're talking about CL_GUI_ALV_GRID.

Yes, Sandra, sorry, I was talking about CL_GUI_ALV_GRID
