Edit tree structure online

Is it possible through flex to edit a tree structure online. Such as creating a new model, adding a sub level or deleting a level. If not then is it possible to do this through asp.net?

What you are looking for can be found at www.pectora.com. They have an online webeditor that can do the job. However it is part of a high-end solution and could turn out to be pricey :-)
Pectora is also part of a solution called IMMIX. It involves a CMS system called Sitecore and communicates directly with InDesign/InDesign Server.

ATP Tree Structure is not getting created automatically after Sales Order is saved

In one one of our scenario, when we add material to Sales Order and save with Requirement Type(under Procurrement Tab of Sales Order) , in APO there is no planned order or only planned order which is dynamically pegged created because the ATP Tree in APO is not being converted. There is no pegging relevant item create(e.g. Planned Order). When we are checking the persistent ATP Trees in APO (/SAPAPO/ATREE_DSP - ATP-Trees) we can see that they are not converted automatically. They are still there. If we do it manually via transaction (/SAPAPO/RRP_ATP2PPDS - Conversion ATP Tree Structures -> Production Planning) it works. Afterwards the Planned Order is available and fixed pegged.
Why is APO not converting the ATP tree automatically ?
I also checked the scheduling horizon for conversion of the ATP Tree and it is correct: Is there any relation with Check Mode setting under ATP tab in Material Master?

Hi Prasad ,
This enables you to debug the ATP tree . If you have created an entry here with your user name then it will not let ATP tree get converted into PP/DS orders automatically .
It's very surprising because all seems fine . Just cross check all the settings once with below .
The conversion time depends on the following horizons and dates:
· PP/DS Horizon
· Scheduling horizon for the conversion of ATP tree structures
· Requirements dates in the ATP tree structure
PP/DS immediately converts the ATP tree structure when the sales order is saved
· If the earliest requirements date for components is within the scheduling horizon or
· If the latest requirements date for finished products is within the PP/DS horizon
If none of these conditions are fulfilled when saving the sales order, the system saves the ATP tree structure in SAP APO. In this case you can only convert the ATP tree structure online or in the background when one of the conditions given above is fulfilled. Here, there is an offset for the horizons with which you can achieve an earlier conversion.
You maintain the scheduling horizon for the conversion of ATP tree structures in Customizing for Production Planning and Detailed Scheduling under Maintain Global Parameters and Defaults. You maintain a location product specific PP/DS horizon in the location product master. If no location product specific PP/DS horizon exists, the system uses the PP/DS horizon from the planning version. You maintain these in Model and Planning Version Management.

How to create a tree structure using forms.

Hi,
How do i create a tree structure using oracle forms,i have a table named Functions and a specific column 'Function Name' should be displayed in the tree nodes.Can anyone help me out on how to create a tree structure and populating the nodes??
thanks in advance

The FTree package provides functions to populate the tree - look for the topic "Manipulating a hierarchical tree at runtime

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:

How to populate Tree structure from BAPI while tree grows or shrinks

Hi All
Currently I am populating the tree structure from BAPI based on the HLevel (Hierarchy Level) parameter, but when ever insertion and deletion happens in the tree at any level in the UI and at the same time i am updating these tree node values with HLevel value(example : 1 is first level , 2 is second level, 3 is third level etc) updating successfully& correctly into the BAPI, no issues.
Once it is updated into the BAPI, next time when i refreshed the UI then i am not populating the tree structure correctly from BAPI with updated new nodes based on the HLevel. when tree struture grows or shrinks in the BAPI after updating into BAPI from UI then i am not populating the tree sturcture correctly based on the HLevel value from the BAPI.
Please let me know any sample code how to populate tree structure correctly when tree structure grows or shrinks based on the HLevel value ( Hierarchy Level , for example : 1 is level , 2 is 2nd level , 3 is third level nodes etc)
anybody helps in this regard with sample code on the populating tree tructure then it would be great help to me.
Thanks in advance

Denis,
Do you have [red hair|http://www.dennisthemenace.com/]? ;-)
My advise with the tree structure is pretty short and sweet... make each node remember
1. it's parent
2. it's children
That's how the file system (inode) actually works.
<quote>
The exact reasoning for designating these as "i" nodes is unsure. When asked, Unix pioneer Dennis Ritchie replied:[citation needed]
In truth, I don't know either. It was just a term that we started to use. "Index" is my best guess, because of the
slightly unusual file system structure that stored the access information of files as a flat array on the disk, with all
the hierarchical directory information living aside from this. Thus the i-number is an index in this array, the
i-node is the selected element of the array. (The "i-" notation was used in the 1st edition manual; its hyphen
became gradually dropped).</quote>

Search help like tree structure.

Hi All,
I have a requirement to display the F4 search help like a tree structure , with different
Node(category fields ), under each node(category fields ) different work centers will exist.
Please suggest how I can achieve the tree format categories in search help.
Thanks for your cooperation.
Thanks,
Sri.

Hi Sri,
U can have a look at the search help PRCTH in se11, which has an search help exit K_F4IF_SHLP_STANDARD_HIERARCHY
just execute this and try to debugg it...
Hope this solves your problem...
please ack if helpful .
Best of luck !

WDA: Tree structure in web dynpro for ABAP

Hi,
I am trying to build a tree structure with information something like the following:
Country
State
City
I used the UI Element "Tree" and I was successful in building it. The only problem is that it supports only one column in each row like name.
I need multiple columns in each row like Name and population.
1) Is there any solution for this using UI element "Tree" only?
2)I checked that there is Table tree UI element, but I could not figure out how I could use it for hierarchial structure like that of my requirement? Can I use it? Is there any example application with hierarchial structure?
3)For tree UI element, any node that is not directly below context node has to be non-singleton. It will lead to adverse performance. Is there any solution for this?
Thanks in advance.
Regards,
Srini.

Hi Srinivasa,
In the context, please create a node DATA with the following fields:
KEY type string
PARENT type string
LOCATION type string
POPULATION type string (or "I" if you happen to have numbers only without a unit like "k" for "thousand").
Then please create a table with a TreeByKeyTableColumn namde LOCATION and an additional TableColumn called POPULATION. Now please add a TextView cell editor to both and bind the text value of each of them to the attributes LOCATION and POPULATION of the context node DATA. Last step is to bind the attribtues rowKey and parentRowKey(?) to the KEY and the PARENT attributes. This concludes the design time part.
Next step is to fill the node DATA with actual data. Just use a supply function and do it like this:
First entry:
KEY = 'WORLD'.
PARENT = ''.
LOCATION = 'World'.
POPULATION = '4 billion'.
Second entry:
KEY = 'DE'.
PARENT = 'WORLD'.
LOCATION = 'Germany'.
POPULATION = '80 million'.
You should now see a table with a tree at the left column that looks like:
<pre>
World 4 billion
->Germany 80 million
</pre>
Kind regards,
Thomas

Regarding Tree structure display in Webdynpro ABAP

Hi Experts,
I am very new to webdynpro ABAP , I was asked to implement some functionalities of RWBE transaction in webdynpro , in RWBE transaction list can be displayed as Tree structure , in webdynpro how i can implement this ? using ALV UI element is it possible . Please help .

Hi ,
I need an output like the below
<material number                 a1           a2        a3

<material number                 A1          A2       A3
is it possible to show the output as in this format using ALV ?.
I have tried with the help provided by SDN , but not succeed .
also i need to capture double click event and show the currosponding result in a seperate view.
here material number is the parent node , plant and org were child nodes

Tree Structure Implementation in Java.

1>
How should i implement a "Tree Structure" in Java Based application.?How would i map the entries to the database table?how many tables will i require for this implementation.?
List records<String> = new ArrayList<String>();
records.add("null");
records.add("Product");
records.add("Category");
records.add("P1");
records.add("P2");
records.add("P3");
records.add("C1");
records.add("C2");
records.add("C3");
so how should i implement a Tree Structure for the above record set.
//P1,P2,P3 belong to Parent {Product}
//C1,C2,C3 belong to Parent {Category}
Sample code provided will be helpful

How should i implement a "Tree Structure" in Java Based application.?The quotes suggest you don't know what a tree structure is, regardless of the development language. Fix that first (your understanding of what a tree structure is). [url http://en.wikipedia.org/wiki/Tree_structure]Here is probably a good start.
How would i map the entries to the database table?how many tables will i require for this implementation.?It depends on what your tree structure represents, in particular it depends on whether the leaves and intermediate nodes of the trees have are homogeneous (e.g. have a common interface). There is no general rule.
I suggest you start by looking in the Java API at all the classes whose names start with 'Tree' (TreeSet and TreeMap are probably the best ones to start with) and read the documentation carefully. Then try to write some code that uses one and come back if/when you have any problems.(sorry Winston) I think this is a very bad advice.
These classes are particular implementations, respectively of a set (in the mathematical sense) and of a map (associative table), which happen to use a "tree structure" for their internal business. Their API doesn't help building a custom "tree structure" (they may be used that way, but it's certainly not the easiest nor even a particular handy way to build tree structures).
Maybe their implementation may be a good example of how to build a Tree structure, but they use a particular type of tree (+red-black tree), not a general one. This may or may not be the OP's case, I wouldn't bet on it.
OP you're welcome to come back with more specific questions and details. Good luck with Java.

After checking the Javadoc: indeed TreeSet only uses a TreeMap for its implementation, so the only one out of the two which does directly uses a tree structure in its implementation is TreeMap.
Edited by: jduprez on Oct 16, 2010 2:51 PM
And, to reiterate, I stand by my claim that TreeMap is not a good example of a general Tree structure: in particular it uses a tree to map keys to values, its main business is the "mapping" part, not the tree as a storage medium. Neither the keys nor the values know anything about their "children".

How to create a tree structure,like I want to create Bill/Payment Tree

How to create a tree structure , like I want to create a Bill/Payment Tree containing a single node for all A/R related activities for a specific bill period, in reverse chronological order. Basically the tree should look like
+ Bill - Date: 03-17-2010 Complete
+++++ CR Note - Date: 05-04-2010 Complete
++++++++++ Pay - Date: 05-04-2010 Frozen
+ Bill - Date: 03-17-2010 Complete
+++++ Pay - Date: 05-04-2010 Frozen
And finally this should be attached as tab on the control central

The FTree package provides functions to populate the tree - look for the topic "Manipulating a hierarchical tree at runtime
" in the online help this point to all the functions and triggers

WebLogic missing data on JNDI Tree Structure

I need to work with Tuxedo through WebLogic, but I am having a bad time trying to figure what is going wrong in here. I have installed WebLogic 10.3 twice and still can't make it right.
In the JNDI Tree Structure many data is missing (among them tuxedo) and can't find a way to fix it.
Please, if anyone can give me a light I'll appreciate it.
Regards.
Pablo Bustos.
EDIT: I am running WebLogic 10.3 on Windows XP 32bits.

Hi,
Check this debug in ur environment.
-Dweblogic.jndi.retainenvironment=true
this should show you the path.
