ALV (or not) table as a tree

[Former Member]

Hello,

I am trying to display an ALV table with the first column behaving like a tree. Basically all rows will be empty (except first column) except the leaf elements.

I have explored the following solutions, and each solution brought questions:

1. Using the standard table UI element:

This works fine, and it is very clear how to build the hierarchy of nodes either by using a recursion node, or by using the path/parent_path attributes. However I cannot find any way to have the view selection (with Filter and Settings buttons) at the top of the table, which bothers me a lot.

Is it possible to have this toolbar with the table UI element ?

2. Using the reusable ALV table component SALV_WD_TABLE:

Here I have the view selection toolbar. I have also managed to have a very simple tree with the first column as a hierarchy column (using the if_salv_wd_column_hierarchy and if_salv_wd_table_hierarchy methods on columns and table config).

My problem here is that I don't understand how to manage multiple hierarchy levels. The entries are grouped and collapsed if they have the same value in the hierarchy column, but I don't see how to make something like "level1 -> level2 -> entry1", I have only a 1 level tree like "level1 -> entry1,entry2,...". Is it possible to have the same flexibility on building the hierarchy levels as with the table UI element ?

Thanks in advance.

Sorry but since I posted in the Webdynpro ABAP section, I thought it obvious that I was working in Webdynpro ABAP. Your link is about ALV tree in classic dynpro programs.

In WD ALV, you can still make one more column as hierarchy column, You can get 2 levels right.

I understand but that's my problem: I cannot add columns as hierarchy columns, because the whole hierarchy is based on one column, and the number of levels is not known until runtime.
