Answer 1

Procedure is :
a) Get ALV Model reference
b) Get list of ALV Columns
c) Loop at each column and set visibility
Code would be something like this
I'm storing ALV model reference in view attributes wd_this->alv_config_table of type ref to CL_SALV_WD_CONFIG_TABLE.
Data: lo_cmp_usage type ref to if_wd_component_usage.
  DATA: lr_salv_wd_table TYPE REF TO iwci_salv_wd_table.
  DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings,
        lr_column          TYPE REF TO cl_salv_wd_column,
        lt_column type salv_wd_t_column_ref,
        ls_column type salv_wd_s_column_ref.
*create an instance of ALV component
  lo_cmp_usage =   wd_this->wd_cpuse_OVERVIEW_EARNED_ALV( ).
* if not initialized, then initialize
  if lo_cmp_usage->has_active_component( ) is initial.
    lo_cmp_usage->create_component( ).
  endif.
* get ALV component
  lr_salv_wd_table = wd_this->wd_cpifc_OVERVIEW_EARNED_ALV( ).
   wd_this->alv_config_table = lr_salv_wd_table->get_model( ).
  lr_column_settings ?= wd_this->alv_config_table.
  lt_column = lr_column_settings->get_columns( ).
  loop at lt_column into ls_column.
    CASE ls_column-id.
      when 'POST_YEAR'.
        ls_column-r_column->set_visible( if_wdl_core=>visibility_none ).
   ENDCASE.
endloop.
