Tree hierarchy in F4 help

hi all,
I have a requirement like,
in transaction VBG1/2/3. i have to add a 5th tabstrip "MC Hier" and this tab structure is same as the one of 4 structre, But in one field Merchandise Category when we click on F4 for data selection then it should show a tree structure.
The search help should show a tree. The tree should start with one entry u201CRIMOSu201D. If there are children to a branch a + should be shown in the tree. Selecting the hierarchy number should put the hierarchy number in the u201CMC Hieru201D field.
The hierarchy can be read by reading tables:

please help me how to do it ...

BW Tree Hierarchy-multiple selection for query possible?

Hello,
I have a question in regards to BW Tree Hierarchies and its usage in Bex Reporting:
Is it possible to select multible Tree Hierarchy (based on the same characteristic) when executing a query in Bex Analyzer. If yes, how?
I tried to configure this by making use of a hierarchy variable on the characteristics, but it does only allow me to select one hierarchy.
Thanks for your help,
Elisabeth

Elisabeth,
Your query can only assign one hierarchy per characteristic.
If you need multiple ones - I'd suggest you make a query per hierarchy and you can user Query Views in the WAD to let the user select the View (i.e.. the Hierarchy) they wise.

Gill

How can I create a tree hierarchy in Adobe Flash with WD Java?

Hello!
I've started to learning RIAs based on WD Java and Adobe Flash. Now I need to create application with tree hierarchy. Nodes of hierarchy must be able to collapse and expand. Hierarchy must looks like in https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0c91fc0-932d-2c10-4ca7-f5774950c8e3 (first section)
Does anybody know where I can get a tutorial for such hierarhies or which control element I have use?
regards, Lev

well, Network UI should be used.

Oracle Tree Hierarchy Query

Hi,
Hoping someone can assist with this query:
I am currently using this query to construct a tree hierarchy, i.e.
SELECT "EMP"."MGR" as "MGR",
        "EMP"."EMPNO" as "EMPNO",
        "EMP"."ENAME" as "ENAME" ,
        (select count(*) from "EMP" "EMP2" where "EMP2"."MGR" = "EMP"."EMPNO") BranchCount
from
"EMP" "EMP"
where
"EMP"."MGR" = :BRANCH_IDUsing this query, I also need to retrieve the LEVEL pseudo-column as well for each record retrieved as I need the LEVEL info for trying to determine at what level of the tree I am at.
I would actually like to incorporate the LEVEL column into the above query - is this possible?
Thanks.
Tony.

Hierarchy in F4 help

Hi,
     I have written a program which should accept material hierarchy as input. Please let me know if there is any function module to invoke the hierarchy tree structure in the selection screen of a program just as it appears in a BW query.

Error when moving Exchange Public Folder Tree Hierarchy

Hello,
I am during the transition from Exchange 2003 to 2007.
At the end of migrating Exchange 2003 to Exchange 2007 I have moved all the mailboxes, Public and System Folders have been replicated and moved, Mailbox Store and Public Store had been removed, Routing Connectors removed ...
I then created new Public Folder Container in Exchange Administrative Group (FYDIBOHF23SPDLT) and I attempted to drag and drop the Public Folder Tree Hierarchy from old Administrative Group to Exchange Administrative Group using ESM 2003.
During this I got the following error:
Access Denied.
Facility: LDAP Provider
ID no: 8007005
Exchange System Manager
Every public and system folders works fine (replicated to Exchange 2007), but the Public Folder Hierarchy is still on Exchange 2003.
Anyone has any idea how to continue decommission of Exchange 2003?
Regards,
Jacek

As I wrote before, when I tried to drag and drop the Public Folder Tree Hierarchy, I used account which had delegated Exchange Full Administrator role in Exchange 2003 and was also member of Enterprise Admins / Domain Admins in AD and Exchange Organization
Administrators in Exchange 2007. According to Sembee suggestion, it is more than needed ...
I think about manual deleting Public Folder Tree Hierarchy object from old Administrative Group (using ADSIEdit) and then recreating the new one in Exchange Administrative Group - using the following steps:
http://blog.bruteforcetech.com/archives/766
But I'm not sure if System Folders will be accessible then. There are many Outlook 2003 in organization, so "old" OAB access is necessary ...
I can take report of permissions for the problematic Public Folder Tree Hierarchy object using dsacls.exe, if needed (there are many ACEs in DACL on them). I can also check Effective Permission for user I used for moving.
But in both cases, I don't have any reference. I mean correct permission set for such object or necessary permission set for user used for moving.

Jacek

Hi
Has anyone used webservices to display theproduct structure in a product tree hierarchy format using webservices.
Kindly provide your inputs.
Thanks

Do you want to display the alt text on image?
If so you can directly use alt="<your product description>" on the img tag
eg:
<dsp:getvalueof var="prodDetail" param="product.description"/>
<img src="/path/to/your/img" alt="${prodDetail}"/>

hi,
to populate the dropdown list you can do it...
1). manually or
2). by code
1). <b>manually</b> go to interactive form->edit
     go to Object tab->field tab ->
     you must see something like
     List Items :
     Text     + x
     click on the green + sign...
     it promps you to type. type in the value press enter... and so on...
2) <b>by Code...</b>
    //set up contents of a drop down list dynamically...
    IWDAttributeInfo countryInfo = wdContext.nodeTravelData().getNodeInfo().
            getAttributeInfo().getAttribute("DestinationCountry");
    ISimpleTypeModifiable countryType =
            countryInfo.getModifiableSimpleType();
    IModifiableSimpleValueSet countryValueSet =
            countryType.getSVServices().getModifiableSimpleValueSet();
    countryValueSet.put("1","Germany");
    countryValueSet.put("2","UK");
This will work....

Building Tree hierarchy Using nested loops and class cl_gui_column_tree

Hello gurus,
I want to create a tree report using custom container and class cl_gui_column_tree. I have read and understood the standard demo report which SAP has provided i.e. SAPCOLUMN_TREE_CONTROL_DEMO. But in this report all the levels nodes are created as constants and hardcoded. I want to create hierarchy using nested loops. For this i took one example of a hierarchy of VBAK-VBELN->VBAP-POSNR Like One sales order has many line items and each line item can have number of line items in billing plan.
I have done some coding for it.

ENDFORM.
Now this program compiles fine and runs till there is only one level. That is root->vbeln. But when i add one more loop of it_posnr it gives me runtime error of message type 'X'. The problem i found was uniqueness of item-item_name as all the sales order have posnr = 0010. What could be done? I tried giving item_name unique hierarchy level using counters just like stufe field in prps eg. 10.10.10, 10.10.20,10.20.10,10.20.20,20.10.10 etc.. etc.. but still i am getting runtime error when i add one more hierarchy using nested loop. Plz guide.

Hello all,
Thanks the issue is solved. The node key was not getting a unique identification as nodekey. I resolved the issue by generating unique identification for each level. Thanks all,

How to build tree/hierarchy/explorer format in internal table

Dear Friends,
I have one internal table with parent and child, again child will be acting as parent and it can have further childs ......
like that it goes on there is no constant levels it goes on....
for example.
parent child
100 101
102
103
101 201
202
102 301
103 401
402
403
this has to be displayed in hierarchy mode.
here i to as a column wich has to represent its position/level in the hierarchy like:
1
1.1
1.1.1
1.2
1.2.1
......n
1.2.2...n
1.3
2
2.1
2.2
3
etc...
let me know any ideas to get the maping of the rows to put it in tree format( like windows explorer).
Thanks,
Mahesh.Gattu

tree component is working perfectly. But according to my requirement i need to sort the date in tree.
Iam trying that since 2 days but not able to find any solution.
can any one help me plz.
Thanks in advance.

Check this thread:

This would provide the required inputs for sorting the tree.
Thanks,

Tree Hierarchy in Web Dynpro

Hello All,
I want to create a web dynpro application that implements some functionlity that I saw in the SAP backend system. In the backend, I have a transaction that allows me to drill down into nodes and add and remove them with a right click context menu. This is like a tree structure with the ability to add, remove and modify node elements. I want to present this to the front end user using web dynpro and possible in a nice table format. How can I go about doing this? Any suggestions?
Thanks
Marshall.

Ok, I try to explain with a simple example.
Say, your context has the following structure:
WebDynproClass (node, cardinality=0:n)
- expanded (boolean)
- name (string)
- SubClasses (recursive node -> Class)
Then, you can build the following tree:
UIElement (root)
+ AbstractCaption (e_1)
   + AbstractButton (e_1_1)
      + Button (e_1_1_1)
+ RadioButton (e_2)
with code like
/* helper method, put inside //@@begin others...//@@end section */
private IWebDynproClassElement addSubClass(String name, IWebDynproClassElement parent)
IWebDynproClassElement child = (parent == null)
    ? wdContext.nodeWebDynproClass().createAndAddWebDynproClassElement()
    : parent.nodeSubClasses().createAndAddWebDynproClassElement();
child.setExpanded(true);
child.setName(name);
return child;
/* builds initial tree, call from wdDoInit() */
private void init()
IWebDynproClassElement root = addSubClass("UIElement", null);
IWebDynproClassElement e_1 = addSubClass("AbstractCaption", root);
IWebDynproClassElement e_1_1 = addSubClass("AbstractButton", e_1);
IWebDynproClassElement e_1_1_1 = addSubClass("Button", e_1_1);
IWebDynproClassElement e_2 = addSubClass("RadioButton", root);
Now if you want to add "Caption" as subclass of "AbstractCaption" later, you have to find the context element that represents the "AbstractCaption" class and add it as above:
IWebDynproClassElement parent = find("AbstractCaption");
addSubClass("Caption", parent);
If you have to implement the find() method at all depends on your application. Maybe you want to
- provide a context menu (available since 7.1) on the tree nodes to add child nodes, or
- provide a static menu at the table cell editor (since 7.0)
- you provide a toolbar button to add a child node to the currently selected tree node (since 6.40)
Example for a static menu at a TextView cell editor:
Table (dataSource = WebDynproClass)
+ TreeByNestingTableColumn (expanded = WebDynproClass.expanded)
   + TextView (text = WebDynproClass.name)
      + Menu
         + MenuItem (id = AddChildItem, onAction = AddChild, nodeElement -> AddChild.parent)
Action "AddChild" has text "Add Child" and a parameter "parent" of type IWebDynproClassElement. Action handler is
public void onActionAddChild(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.sap.demo.rec.treetable.comp.wdp.IPrivateMainView.IWebDynproClassElement parent )
    //@@begin onActionAddChild(ServerEvent)
    addSubClass("Child #" + parent.nodeSubClasses().size() + " of " + parent.getName(), parent);
    //@@end
Then you will get a menu at each tree node with an entry "Add Child" that adds a new child node with some generic text.
