F4 for employee select options in WD for abap application

Question

Hi,
I have defined a select option for employee selection in my WD for abap application. The only problem is that I cannot get a f4 help button to be displayed. I have defined the select option using the following code :
wd_this->m_wd_select_options = wd_this->wd_cpifc_select_options( ).
init the select screen
wd_this->m_handler = wd_this->m_wd_select_options->init_selection_screen( ).
create a range table that consists of this new data element
lt_range_table = wd_this->m_handler->create_range_table(
i_typename = 'PERNR_D' ).
add a new field to the selection
wd_this->m_handler->add_selection_field(
i_id = 'PERNR_D'
it_result = lt_range_table
i_read_only = read_only ).
I have tried adding entries for the parameter help_id but still cannot get a f4 button.
Thank you in advance for any assistance provided.

Hi,
Try this.
DATA lo_interfacecontroller TYPE REF TO iwci_wdr_select_options .
lo_interfacecontroller = wd_this->wd_cpifc_select_options( ).
DATA lo_r_helper_class TYPE REF TO if_wd_select_options.
lo_r_helper_class = lo_interfacecontroller->init_selection_screen( ).
Creating range table
DATA lt_range TYPE REF TO data.
CALL METHOD lo_r_helper_class->create_range_table
EXPORTING
i_typename = ''PERNR_D'
RECEIVING
rt_range_table = lt_range.
Disabling the global options
CALL METHOD lo_r_helper_class->set_global_options
EXPORTING
i_display_btn_cancel = abap_false
i_display_btn_check = abap_false
i_display_btn_reset = abap_false
i_display_btn_execute = abap_false.
Adding the selection field
CALL METHOD lo_r_helper_class->add_selection_field
EXPORTING
i_id = 'PERNR_D'
I_OBLIGATORY = ABAP_TRUE
i_value_help_type = if_wd_value_help_handler=>CO_PREFIX_SEARCHHELP
I_VALUE_HELP_ID = 'PREM'
it_result = lt_range.
Check this artcle for more details which uses VBELN as select option with search help.
