Refresh functionality of a tree structure......
Hi Friends,
In my application i have a Tree structure and when i click on the root node i get the sub-elements under this and when i select an element and execute this element gets deleted/removed.
Now the problem is such that the element is getting deleted in the backend(R/3),but i am able to see the element in the structure still.
When i click on Refresh icon i cannot view the element.
I have tried to used invalidate method,reset method but still the problem remains the same.
Is there any solution to refresh the application manually without clicking on Refresh.
Please help me out to proceed further.
Thanks and regards,
Chandrashekar.
go to view properties and set Life span as when_visible.
or each time you need to call the RFC execute method whenever you delete or change tree elements

How to Use Tree Structure in Forms (Expand & Collpse)
Hi ,
I need a logic to develop a Custom form which using tree structure fuctionality.It's like same in Indented Bills form (Module Bills of Material).
I have to use the symbol '+' and '-' in column called item_number ( if it has sub componentes, using that symbol i may explode or collopse).
I gone through the base form for that(indented Bill form(Form Name:BOMFQBIN, using BOMFMSTR library function to create Tree Structure)
but i colud not understand the logic.
If any one clarify me then it's fine
Thanks,

Sidebar expand folder functionality/ file tree structure
Is there a way to get "favorites" that I've added to my sidebar to expand in Mavericks? I'd like to show a file tree structure in the sidebar. This would make it SO much easier to move image files one folder up. Right now I have to have multiple folders open or have columns view which doesn't enable me to have a usable thumbnail preview in the working folder. Please help!
--FrancescaNo. The sidebar does not provide that; there's no hierarchical navigation within the sidebar.
If not already doing so, you might consider using tabs for your various Finder views.
Otherwise, there might be a different option available as a Finder alternative. -

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

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,
LakshmiHi 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.

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
Regards
Kalki Reddy

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

Multi-selection using windows style tree structure
We developed a solution to replace the standard multi-select functionality with a java based tree structure where upon selection of a node all sub-entries are selected. These entries are then added to the selection.
Performance is however a problem and I would like to know if anyone has experience of implementing such a solution or if there is an alternative standard solution.
regards
TimHello Tim,
Did you try to run an SE30 performance analysis ?
Check out this OSS note:
Note 948066 - Performance Analysis: Transactions to use
And depending on your CRM version, be aware that you can use the ABAP shared memory concept, which will considerably reduce the amount of memory used... hence increasing performance.
Ciao,

when i enter america and enter submit;the country should come in the left frame;i will refresh left frame when click submit;ofcourse i know that;like wise when i click state hyperlink
state name ---------
description ---------
statename should come under state tree node;
i will also maintain this info in database also;i am using oracle9i;how can i do this the tree structure;how to approach;if anybody give me any links revelant to this?atleast give me some idea what to do?please dont give me the DOM tutorial or SAX Tutorial cos i already gone through but i didnt get any idea.

How to draw a graph of tree structure (using shapes and lines)?
Hello,
I tried to search this solution in the forum, and I see people asking and replying with solutions to similar situation, but I don't get what I am looking for. Also because I have never tried with graphs before.
So, my problem is, I need a function that takes a string with tree structure, as in automata or tree graph, and displays the nodes in tree form. "Tree" is not important, but important is that each object should be displayed as a node and lines connecting them. Please see the image below (with three possible options):
So, basically, the tree structure could be like X(a, X(a,b), c) where X(a,b) is a sub-tree of higher level X. The program knows the parent-child relationship, so this function only needs to display those elements in a graphical fashion.
I pass the string in the form of a 2D array showing the hierarchy (to simplify).
In the image, I am showing three possible options for showing the tree. The third option eliminates those circles and rectangles, if that simplifies.
I hope I explained clearly.
Thanks ahead!
VaibhavI would start drawing from the top. The nodes will be the easy part.
Begin with the root node centered in the drawing area horizontally and against the top of the drawing area. The second row of nodes would be located vertically (as in my example) 1.5x pixels below the first one, and either distributed horizontally across the available drawing area or at a fixed distance - like 1.5x again, or someother distance you define.
The tricky part will be drawing the lines since they need run between the edges of nodes. This is where the high-school geometry might come in.
Keep us posted on what you come up with. Extra points for coming up with a solution that will automatically resize itself to fit the available drawing area! (I've already given you all the clues for how to do that too.)
