Transfer modified line to handle_data_changed method

Former Member — Fri, 19 Sep 2014 04:08:08 GMT

Hi all,

I have a problem with my ALV OO.

I have several fields, but there is a field (TAX) that I have implemented a F4 help seach by ONF4 method. This help search works fine, but when my try to send the modified row to my my HANDLE_DATA_CHANGED Method in order to loop the modified rows of the ALV, the ->mt_mod_cells is empty

LOOP AT rr_data_changed->mt_mod_cells INTO ls_mod_cells.

Could you tell me how could I save my line previously modified in my F4 help procedure, and transfer this line to my HANDLE_DATA_CHANGED Method and make the er_data_changed contains the row modified?.

Have to say, I am using

CALL METHOD cont_editalvgd -> register_edit_event

Exporting

{}I_event_id = cl_gui_alv_grid => mc_evt_modified

and

ALL METHOD cont_editalvgd -> register_edit_event

Exporting

{}I_event_id = cl_gui_alv_grid => mc_evt_enter

At the same time

Thanks in advance,

Mario

Hi K S!

Mi program has already that line:

SET HANDLER go_event_receiver01->handle_onf4 FOR ALL INSTANCES

I've tried with

SET HANDLER go_event_receiver01->handle_onf4 FOR alvgrid

And it doesn´t work

Any other idea?

Thanks

Hi Mario,

Will be helpful if you can paste your handle_data_changed method code to analyse.

after the SET HANDLER go_event_receiver01->handle_onf4 FOR alvgrid

perform register_f4_fields . "set cells with search help

I use this logic

FORM f_handle_onf4

**§3 set attribute m_event_handled of er_event_data to avoid standard

pls try this and let me know if it helps.
