Webdynpro ALV Tree Structure

[former_member187651]

Hello Experts,

I got an requirement to develop ALV tree structure with multilevel (level do not know at design time). I have gone through SDN but didn't found any relevant answer.

Currently I am using the way as follows:

My Node structure is :

I am using Code with in WDDOINIT method of Componentcontroller is as below:

data: l_ref_cmp_usage type ref to if_wd_component_usage.
   l_ref_cmp_usage =   wd_this->wd_cpuse_alv_bucketlist( ).
   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_bucketlist( ).
   data l_table type ref to cl_salv_wd_config_table.
   l_table = l_salv_wd_table->get_model( ).
   data l_column type ref to cl_salv_wd_column.
   data l_header type ref to cl_salv_wd_column_header.

   l_table->if_salv_wd_table_settings~set_width( '100%' ).

  l_table->IF_SALV_WD_TABLE_SETTINGS~SET_DISPLAY_TYPE(
  IF_SALV_WD_C_TABLE_SETTINGS=>DISPLAY_TYPE_HIERARCHY ).


  l_column = l_table->if_salv_wd_column_settings~get_column( 'PRNTB' ).
   l_column->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).



    l_column = l_table->if_salv_wd_column_settings~get_column( 'BUKID' ).
   l_column->if_salv_wd_column_hierarchy~set_hierarchy_column( abap_true ).


   l_table->if_salv_wd_table_hierarchy~set_last_hier_column_as_leaf( abap_true ). 

But it display only the 2 level, i.e 1st it display the 'bukid' then 'parntb' .

My problem is I want to display records of each hierarchy level, like

Root

       child

            child

                  ------

Please give some Ideas, how can I implement the same.

Hi,

One possible approach would be to define hierarchies at runtime in Settings -> Display -> Hierarcy -> Define and save this as views (but it is not as dynamic as you would like).

Best regards,

Thanks for reply.

I did not find the Hierarchy button in the path you have provided...

Settings-->Display-->hierarchy

Actually I need to Implement the ALV tree as like as the Table tree behaves  in the Webdynpro.

I have my internal table filled with values like:

bukid bnumb parent

1       top         0

2        A          1

3         B          2

4        TOP1     0

5       X          4

Here Levels are not defined at run time. I tried with Webdynpro ALV DISPLAY_TYPE_HIERARCHY

I have used a link below:

|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/c060fcb4-2c62-2b10-d2b2-f32407a5cc6f&override...].

but this goes with two levels only...and works differently i.e not same as table tree..

I requirement is to go with ALV tree.....Please let me know..

Any idea........
