Embedding a table in a tree structure in an in WebDynpro application

Hi All,
I need an application that displays a table dynamically in a tree structure as it's child node.
Can any one suggest me how to approach ?

Hi SMI SAP Project Team,
Please check the code for loop and lead selection when you setting the values.
for( f = 0; f < e; f++)
Refer to below documents:
initializing AbstractList Model in Custom Controller

Tree Structure-context-TableUI

I have created a tree structure and I populate the values from tree structure to a table and I have edit button in table if i click edit i can change the value populated from tree structure and my question is how can i get the changed value from table back to tree structure context. can you provide the programming I'm new to java development.
Thanks,
Meenu

Hi Meenu,
first step you need to copy the diaply ttable node to avlue node, then you need to the modifications in the table data, then you need to have a update table node,in as a tables parameter in your bapi, so that you can update the data in the nackend also,
create seprate methods for everymethod returning bapi.
every bpi of rfc a have disply the data and save the data or update the data methods, if it is related to modification of data, please abseve the bapi funcationality to develop the appl;ication.
may be it will help you,

How to create a form on a tree structured table

Hi,
I have a table that is designed to do a tree structure like:
Table Name: test
Fields:
ID
ParentID
Description
I created a browser (IR) (page 1) that calls a form (page 2)
The form has the editing fields and at the bottom layer I have a reports region where I display the children records using a query like:
select * from test where ParentID = :P2_ID
I need at the region level to add a button to call a form to edit the child record (which is the same table) and when done, to return to the form again but to the parent record.
How can I do that successfully? Is there any example:?
Thank you

Maybe this can help:

Integration of a Tree Structure in a Web Dynpro Table

Hi,
I am implementing an Integration of a Tree Structure in a Web Dynpro Table.
The Tree-Table os working as required, but I can not work with the OnLeadSelect Action of the table.
The Action does not work as required, meanning, it returns all the time the first row and not the "lead select".
As far as I read I should add some code to the wdDoModifyView method, but I did not figure out exactly what...
Thanks in advance,

How to use ONE query to find out tree structure?

ID------------upperID----------Name------------------------isFolder
1------------ 0---------- Folder

Folder--------------------1
3------------ 2------------
Folder1-Item1-A--------------------------0

Hi all, if I have a table like above to demonstrate the
folders and item relationship. This structure allows the user to
create unlimited folders and items.
Now I would like to use one query to find out the tree
structure of this table, how could I do the query.
Any help on this will be highly appreciated!
Thanks,

How to create Tree structure in Visual Composer

Hi All,
I need to develop tree structure in my VC application. Can any one of you please suggest me the steps to do it.Its very urgent please can any one help me out in this.
Regards,
Lakshmi

Hi Nutan,
if you want to solve it with webdynpro it depends on your skills in java and abap. There are books available to start with webdynpro and there are examples for building tree structures with Webdynpro.
[Java Webdynpro|http://www.sappress.com/product.cfm?account=&product=H983]
[ABAP Webdynpro|http://www.sappress.com/product.cfm?account=&product=H1916]
If you want to do it in VC you have to write e.g. an ABAP rfc function module, which returns you the tree with the information about childnode, parentnode and so on, so that you can display it in the table. But if the users click on sort then the tree is "destroyed". You can also display only a few levels of your tree and when you select a certain node a drill down is done by calling a rfc which returns the child nodes of the corresponding node.
But I think the solution with VC is not the best. Use webdynpro for this requirements.
Best Regards,
Marcel

How to get the folder name of selected subitem in tree structure?

Hi All,
           I created a tree structure like below.
         ->Folder1-- 1
                          2
                          3
        ->Folder2-----1
                           2
                           3
                i.e i have two folders & each folder having the values like above.Now i want to perform some action by clicking on the any of the values.Suppose if i click value 2,i want to do some action.the actions need to perform is varies from floder to to folder.
        So How can i get the folder name of clicked Value?
Regards,
Ravi

Hi Kumar ,
the below code should help you.
Register the below action for the leaf node for which u need the subfolder's name above it.
Worked fine in my system ...hope it does in ur scenario too
method ONACTIONGET_PATH .
data : lr_element TYPE REF TO if_wd_context_element,
         lr_node TYPE REF TO if_wd_context_node,
         ls_path type string,
         ls_path_node TYPE string,
         lt_string type TABLE OF string,
         l_lines type i,
         l_lines_1 TYPE i.
lr_element = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
**-> getting the path of the node/leaf
*which u had clicked and from that getting the node above it
ls_path = lr_element->get_path( ).
SPLIT ls_path at '.' into table lt_string.
-> remove the first 2 entries as they will contain the view name
DELETE lt_string FROM 1 to 2.
l_lines = LINES( lt_String ).
l_lines_1 = l_lines - 1.
-> remove the last 2 entries as they will contain the element in the path
DELETE lt_string from l_lines_1 to l_lines.
LOOP AT lt_string into ls_path.
    CONCATENATE LINES OF LT_STRING into ls_path_node SEPARATED BY '.'.
ENDLOOP.
**-> getting access to the node above the leaf element
LR_NODE = WD_CONTEXT->PATH_GET_NODE( path = ls_path_node ).
lr_element = lr_node->get_element( ).
**-> Getting the name of the folder...
*here path is the attribute in my context which stores the name of the folder
lr_element->get_attribute( EXPORTING name = 'PATH' IMPORTING value = ls_path ).
endmethod.

Display Tree structure using EVS or OVS

Hi All,
Here we have a requirement like display tree structure when I press F4. currently the sample application (using Object Value Selector or Extended Value Selector) is displaying the values in table, instead of table here we have to display it in tree.
If it is not possible using either OVS or EVS please tell me what is the other way to solve the problem.
Please give me any suggestion.
Regards
Suresh

Suresh,
You can emulate the behaviour by having a separate view for the tree structure.
1.) Create a new view and put your tree structure UI + related logic in that view.
2.) Create an input field and a linkToAction / button (with the text "Search".) aligned side by side.
3.) On click of the search button, show the view containing tree as pop-up.
You may develop upon this hint to meet your requirement.

Tree Structure - Is it possible to Open a Pop up/external window on select

Is it possible to Open a Pop up/external window on select of any Leafe node or a parent node?
My requirement is to create a webdynpro screen which depicts the transaction :
ooqa in sap R/3.
Is it possible to do that in tree structure?
Thanks & Regards,
Sirisha.RS

Hi Ayyaparaj,
Thanks for ur reply.
but i cant use a table here. I just need a tree structure..
I guess Its posible by writing a code for a external window open in the onselect method itself.
Thanks & regards,

JPA - tree structure mapping    with toplink essential

I'll try to explain it correctly.
I store a tree structure in a database. I have just two tables:
Node which contain a id , and some other info.
Tree which contain a parent and child
parent and child are ids from node.
Since each node can have several childs, and each node can have several parents, I had try a @ManyToMany relationship without sucess.
Here one small example of my tries :
@Entity
@Table(name="node")
public class Node {
@Id private int id;
private List<Node> childs;
private List<Node> parents;
@ManyToMany
@JoinTable(name="Tree")
public List<Node> getParents(){
     return parents;
@ManyToMany(mappedBy="parents")
public List<Node> getChilds(){
     return childs;
}But I always got several error.
Anyone have a working example that look like mine ?
Even after googling for several hours I still find nothing.
If it helps, I use toplink essential for my persistance layer.

Please see http://www.oracle.com/technetwork/middleware/toplink/index-085257.html for information on TopLink JPA support.
So as of TopLink 11, you will need to use EclipseLink's org.eclipse.persistence.jpa.PersistenceProvider as the provider class for JPA support, which is in the eclipselink.jar.

Chris

Hi,
Thanks for providing the CREATE TABLE and INSERT statements; that helps a lot.
You want featureids that meet three criteria:
(1) there is a GID attribute
(2) the GID attribute has a GNR child with intvalue=123
(3) the GID attribute has a BNR child with intvalue=456
Since you're looking for immediate children, not distant descendants, it's easiest to do this with a non-hierarrchical query that finds one of these criteria, and does EXISTS sub-queries to test for the other two.
For example:
WITH aat AS
( -- Begin aat: join of attribute and attributetype
     SELECT     a.featureid
     ,     a.id
     ,     a.parentid
     ,     a.intvalue
     ,     t.name
     FROM     attribute     a
     JOIN     attributetype     t     ON     a.atttypeid     = t.id
) -- End aat: join of attribute and attributetype
SELECT DISTINCT     featureid
FROM     aat     m     -- m for main
WHERE     name     = 'GID'
AND     EXISTS     (     -- Begin EXISTS sub-query for GNR=123
          SELECT     NULL
          FROM     aat
          WHERE     parentid     = m.id
          AND     name          = 'GNR'
          AND     intvalue     = 123
          )     -- End EXISTS sub-query for GNR=123
AND     EXISTS     (     -- Begin EXISTS sub-query for BNR=456
          SELECT     NULL
          FROM     aat
          WHERE     parentid     = m.id
          AND     name          = 'BNR'
          AND     intvalue     = 456
          )     -- End EXISTS sub-query for BNR=456
;Alternatively, you could do a three-way self join, and skip the EXISTS sub-queries.
If you were looking for GNR and BNR descendants, any number of levels below the same GID node, it's easy to modify the query above. Just re-write the EXISTS sub-queries to CONNECT BY queries that "START WITH parentid = m.id".
It looks like this application will have a lot of use for a view like aat, above. If you don't already have a permanent view like that, you should create one.
