problem with f4 in alv-grid

[alberto_colonna]

Hello,

I have created an alv-grid with the class cl_gui_alv_grid.

Now I tried to create f4-help for some of the fields in the alv.

The f4-Button is displayed. When I click on it, the f4-window is also displayed but i cannot

choose any value there.

Can you help me?

Kind regards

Alberto

Here is a part of my code:

wa_fieldcat-fieldname = 'OTYPE'.

wa_fieldcat-ref_table = 'ZUSER_ORG_LEVEL'.

wa_fieldcat-style = cl_gui_alv_grid=>mc_style_enabled.

wa_fieldcat-key = 'X'.

wa_fieldcat-f4availabl = 'X'.

APPEND wa_fieldcat TO lt_fieldcat.

wa_fieldcat-fieldname = 'OID'.

wa_fieldcat-ref_table = 'ZUSER_ORG_LEVEL'.

wa_fieldcat-style = cl_gui_alv_grid=>mc_style_enabled.

wa_fieldcat-key = 'X'.

APPEND wa_fieldcat TO lt_fieldcat.

wa_fieldcat-fieldname = 'DATEFROM'.

wa_fieldcat-ref_table = 'ZUSER_ORG_LEVEL'.

wa_fieldcat-style = cl_gui_alv_grid=>mc_style_enabled.

wa_fieldcat-key = 'X'.

APPEND wa_fieldcat TO lt_fieldcat.

ls_f4-fieldname = 'DATEFROM'.

ls_f4-register = 'X' .

ls_f4-getbefore = 'X' .

APPEND ls_f4 TO lt_f4 .

wa_fieldcat-fieldname = 'DATETO'.

wa_fieldcat-ref_table = 'ZUSER_ORG_LEVEL'.

wa_fieldcat-style = cl_gui_alv_grid=>mc_style_enabled.

wa_fieldcat-key = 'X'.

APPEND wa_fieldcat TO lt_fieldcat.

wa_fieldcat-fieldname = 'GUID'.

wa_fieldcat-no_out = 'X'.

APPEND wa_fieldcat TO lt_fieldcat.

wa_fieldcat-fieldname = 'ORGLEVELSET'.

wa_fieldcat-no_out = 'X'.

APPEND wa_fieldcat TO lt_fieldcat.

Checkout demo program- BCALV_GRID_EDIT . It is a good example. You might have to set wa_fieldcat-edit = 'X' in the field catalog for the particular field u r doing F4 on.
