Former Member

Hello to all,

My problem is that : I want Runtime Search Help in ALV Grid

on Field(cell) in each row.

But first of all I have to create a Search Help Icon in that Cell.

Therfore whenever a User click on that cell ,then some dynamic value to be display which I will Capture from database table.

Can we have some field in itfieldcatalog for Search Help(like Hotspot,Edit...)???

Note : Please Don't tell us to refer the Standard Program i.e:

1.BCALV_TEST_GRID_F4_HELP

2.BCALV_GRID_EDIT_DELTA etc..etc...

Thanks.

Vandana.

Steps/

1. in fieldcatalog , what ever field you want F4 , give the f4availabl = 'X'.

gs_fieldcat-f4availabl = 'X'.

2. Register the F4 event and F4 field

gs_f4-fieldname  = 'CONNID'.
      gs_f4-register   = 'X'.
      gs_f4-getbefore  = check_be.              
      gs_f4-chngeafter = chn_aft.               
      append gs_f4 to gt_f4.
      call method my_grid->register_f4_for_fields
        exporting
          it_f4 = gt_f4.

this you can do it before calling the alv display.

3. need to have an event handler for F4.

if you check the alv events

there is an event on_f4

have a local class , and implement the method on_f4.

in side this method you can handle the F4 dynamically

4. set the handler.

this you need to call before or after the set_display method.

set handler my_event_receiver->on_f4 for all instances.

Hello Vijay,

I have done the code as you have suggested, i am getting dynamic f4 value help but i am not able to select it and it doesnt appear in the UI.

Could you please explain it?

Thanks in advance,

Viral.
