<b>Linking F4 Help to Fields</b>
For the last section, we will deal with linking F4 help to fields. It is easy. As usual, define, implement and register the event “onf4” at proper places in your code. For F4 help, you must register the fields whose F4 request will trigger the “onf4” event. For this you must prepare a table of type “LVC_T_F4” and register this table using the method “register_f4_for_fields”. While preparing table you must include a line for each field which will trigger F4 event. For each field in the structure;
&#1048766; Pass the fieldname to ‘FIELDNAME’
&#1048766; Set ‘REGISTER’ to make the field registered,
&#1048766; Set ‘GETBEFORE’ to provide field content transport before F4 in editable mode
&#1048766; Set ‘CHNGEAFTER’ to make the data changed after F4 in editable mode.
DATA: lt_f4 TYPE lvc_t_f4 WITH HEADER LINE .
lt_f4-fieldname = 'PRICE'.
lt_f4-register = 'X' .
lt_f4-getbefore = 'X' .
APPEND lt_f4 .
CALL METHOD gr_alvgrid->register_f4_for_fields
EXPORTING
it_f4 = lt_f4[] .
Preparing table for the fields to be registered to trigger F4 event
METHOD handle_on_f4 .
PERFORM f4_help USING e_fieldname es_row_no .
er_event_data->m_event_handled = 'X' .
ENDMETHOD .
A sample “onf4” method implementation
Again, we set the attribute “er_event_data->m_event_handled” to prevent further processing of standard F4 help.
