hi,

Add a parameter i_obligatory to add selection field with value X.

lr_helper->add_selection_field( i_id = 'S_CARR_ID'

it_result = lt_range

i_obligatory = 'X' <<======

i_description = 'description' ).

And you can use this code to check if there are any mandatory fields in your view or not.

If there are mandatory fields which are empty , it throws an error message " Please fill the complete entries"

data: lt_msg TYPE cl_wd_dynamic_tool=>t_check_result_message_tab,
lo_view_controller TYPE REF TO if_wd_view_controller,
lo_message_manager type ref to if_wd_message_manager.
lo_view_controller ?= wd_this->wd_get_api( ).
lo_message_manager = lo_view_controller->get_message_manager( ).
cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
EXPORTING
view_controller = lo_view_controller
display_messages = abap_true
IMPORTING
messages = lt_msg ).

I hope it helps.
