First get access to the ALV Model object for your ALV usage:
data: l_ref_cmp_usage type ref to if_wd_component_usage.
  l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
  if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
  endif.
  data l_salv_wd_table type ref to iwci_salv_wd_table.
  l_salv_wd_table = wd_this->wd_cpifc_alv( ).
  data l_table type ref to cl_salv_wd_config_table.
  l_table = l_salv_wd_table->get_model( ).
Then access the column you want to change the header on. In addition to setting the text of the header of the column, you must also force off the data dictionary binding for the field property text.
data l_column type ref to cl_salv_wd_column.
l_column = l_table->if_salv_wd_column_settings~get_column( 'POSTING_DATE' ).
  data l_header type ref to cl_salv_wd_column_header.
  l_header = l_column->get_header( ).
  l_header->set_prop_ddic_binding_field(
    property =  if_salv_wd_c_ddic_binding=>bind_prop_text
    value = if_salv_wd_c_ddic_binding=>ddic_bind_none ).
  l_header->set_text( `Posting Date` ).
