About ALV as Hierarchy

[Former Member]

I want to make my ALV like this [https://weblogs.sdn.sap.com/weblogs/images/1918/wda_alv17.jpg|https://weblogs.sdn.sap.com/weblogs/images/1918/wda_alv17.jpg] by coding. I've found a pdf about how to do it, but it doesn't work.

Here is my code:

  DATA:
        l_ref_cmp_usage TYPE REF TO if_wd_component_usage,
        l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table.

  l_ref_cmp_usage = wd_this->wd_cpuse_salv( ).
  IF l_ref_cmp_usage->has_active_component( ) is INITIAL.
    l_ref_cmp_usage->create_component( ).
  ENDIF.

  l_ref_interfacecontroller = wd_this->wd_cpifc_salv( ).
  wd_this->r_table = l_ref_interfacecontroller->get_model( ).

  cl_salv_wd_model_table_util=>if_salv_wd_table_util_stdfuncs~set_all(
    r_model = wd_this->r_table ).
  wd_this->r_table->if_salv_wd_table_settings~set_display_type(
  if_salv_wd_c_table_settings=>display_type_hierarchy ).

  DATA: lr_column TYPE REF TO cl_salv_wd_column.
  lr_column = wd_this->r_table->if_salv_wd_column_settings~get_column( 'CNOID' ).
  lr_column->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).
  lr_column = wd_this->r_table->if_salv_wd_column_settings~get_column( 'STOID' ).
  lr_column->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).

  wd_this->r_table->if_salv_wd_table_hierarchy~set_last_hier_column_as_leaf( abap_true ).

how can i make these code work?

thx

Hi Jiakai,

Refer to this [article|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c060fcb4-2c62-2b10-d2b2-f32407a5cc6f]. It explain the same thing.

I hope it helps.

I've read this article, and my code is copied from it. But I can't understand why it doesn't work...

Hi,

In the article there is line:

data: l_value type ref to cl_salv_wd_config_table. 

But in your code you are using

cl_salv_wd_model_table_util=>if_salv_wd_table_util_stdfuncs~set_all(
    r_model = wd_this->r_table ).

.

I have worked with the 1st statement, I am not sure if the second one has the same functionality. Just see to it. I think if you use the first statement, your problem will be solved.

hi arjun,

it still doesn't work. when i debug it, the system sets the column hierarchy "false"...

the code is like this now:

  DATA:
        l_ref_cmp_usage TYPE REF TO if_wd_component_usage,
        l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table,
        l_value TYPE REF TO cl_salv_wd_config_table.

  l_ref_cmp_usage = wd_this->wd_cpuse_salv( ).
  IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
  ENDIF.

  l_ref_interfacecontroller = wd_this->wd_cpifc_salv( ).
  l_value = l_ref_interfacecontroller->get_model( ).

*  cl_salv_wd_model_table_util=>if_salv_wd_table_util_stdfuncs~set_all(
*    r_model = l_value ).
  l_value->if_salv_wd_std_functions~set_hierarchy_allowed( abap_true ).
  l_value->if_salv_wd_table_settings~set_display_type(
  if_salv_wd_c_table_settings=>display_type_hierarchy ).

  DATA: lr_column TYPE REF TO cl_salv_wd_column.
  lr_column = l_value->if_salv_wd_column_settings~get_column( 'CNOID' ).
  lr_column->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).
  lr_column = l_value->if_salv_wd_column_settings~get_column( 'STOID' ).
  lr_column->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).

  l_value->if_salv_wd_table_hierarchy~set_last_hier_column_as_leaf( abap_true ).

Hi Jiakai,

I don't think there is anything wrong with the code. Make sure that the data is getting fetched properly into the internal table and is properly binded to the node.

hi arjun,

I create a new WD and it works finally...

but how to set the order of the hierarchy column?
