Set column name in ALV table

[Former Member]

Hi folks,

unfortunately, I can't manage it to set a column name in WDA dynamically.

I tried it with the following code, but nothing happened. Any ideas what might be the point?

  DATA lr_config TYPE REF TO cl_salv_wd_config_table.
  DATA lr_column TYPE REF TO cl_salv_wd_column.
  DATA lr_comp_if_alv TYPE REF TO iwci_salv_wd_table.
  DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
  data lr_column_header type REF TO cl_salv_wd_column_header.

  lo_cmp_usage =   wd_this->wd_cpuse_main_incidents( ).
  IF lo_cmp_usage->has_active_component( ) IS INITIAL.
    lo_cmp_usage->create_component( ).
  ENDIF.

  lr_comp_if_alv = wd_this->wd_cpifc_main_incidents( ).   " get component
  lr_config = lr_comp_if_alv->get_model( ).               " get cofig model

 lr_column = lr_config->if_salv_wd_column_settings~get_column( 'My_Col' ).
 lr_column_header = lr_column->get_header( ).
 lr_column_header->set_text( 'My_Col_Name' ).

Kind regards, Steffen

Now I've found a solution.

Deleting the corresponding header column and create it afterwards and set the new text works!!!

[...]  
lr_column = lr_column_settings->get_column( 'My_Col ).

  lr_column->delete_header( ).
  lr_column_header = lr_column->create_header( ).
  lr_column_header->set_text( 'My_Col_header' ).

But I would assume that a single SET_TEXT should do the same.

Maybe anybody knows why not?

Hi Steffen,

after this statement lr_column_header->set_text( 'My_Col_Name' ),

you should add one like: lr_column_header->set_ddic_binding_field( ).

Best Regards,
