Difference between Interface node and normal node?

What is the main difference between Interface node and normal node?
Cheers
Aisurya.

Hi surya,
Interface node or methods comes into picture whenever you want to use one component as used component. I mean to say
Component usages. If you select node as interface node, it will available in another component so you can use that node or methods.
Normal node means in that component only. Simply we can say for component usages we go for interface nodes.
Cehck This...

How to Create Instances in the Transient Root Node and Sub Nodes from Root Node Query Method ?

Hi All,
I am Creating a BOPF BO with 3 Nodes,
Node 1) ROOT -- > contains a query,
using Root Node I have created Search UIBB Configuration in FBI.
In testing -- > when i enter Data in the Search Criteria Fields am able to get the details in to the query method
from Imporing parameter : 'IT_SELECTION_PARAMETERS'.
HERE I am fetching data from a standard table and trying to fill the data in the Node : 'MNR_SEARCH_RESULT'.

I am Unable to set data to the Node . I did not get any error message or Dump while executing . when i tried to retrive data I got the details from the node but am unable to view those details in the FBI UI and BOBT UI while testing .
Please provide your valuable Suggestions.
Thanks in Adv.
Thanks ,
Kranthi Kumar M.

Hi Kranthi,
For your requirement you need only two nodes. Root Node and Result node. Use the same structure for both.
To create Instance while search.
Create Query method with input type which has the required fields for selection criteria.
Fetch the data and create instance in the root node.
Pass the new instance key as exporting parameter form Query Method.
To Move data from ROOT to Result.
Create a action at root node.
Write a code to create new entries in Result node.
Then configure the Search UIBB and display result in List UIBB. Add button and assign the action MOVE_MAT_2_RESULT.
Create another List uibb to display data from Result node.
Connect the UIBBs using wire schema. SEARCH -> LIST(ROOT) ---> LIST(RESULT).
Give src node association for ROOT to RESULT Configuration.

Sunil

Will HANA node supports cluster (Initiator node and Eexecutor node)

Hi Gurus,
In vertica DB supports below cluster concepts, Will HANA supports
Initiator node and Eexecutor node
1. client submits query to vertica cluster the node to which the client is connected is called the initiator node
2. Initiator node analyses query and distributes query plan to executor nodes
3. Executor nodes run query on local data set and return partial result to initator node
Regards,
Manoj.

Hello,
as Vitaliy wrote - you will not find exactly identical equivalent in HANA database but also HANA database can offer similar functions.
In case you want to spread workload across several machines you should check:
SAP HANA Database Server Installation Guide (page 13 - 5.2 Distributed System; page 35 - Adding a Host to the System):
https://service.sap.com/~sapidb/011000358700000604572011
Note: Master nameserver can logcally failover to other node. This can be seen as high availability.
In case you are interested in high availability on instance level - you might want to look as well at following guide:

Invalidate concept for value node and model node

Hello everybody,
We have invalidate method for value node and model node.
I want to know basic concept behind this method.
What this method acually does?
Regards,
Bhavik

Hi Pran and all,
I figured out the problem. Input parameters are going multple times. So, depending upon that it gives multiple values.
My scenario is:
Root Node
|_ Input_node1
     |_Attr1
|_ Input_Node2
     |_Attr2
|_Output_node
     |_Result
I am passing values in Attr1 and Attr2 attributes.
For this, first of all, i wrote following code.
In controller, i have initialized Root node:
Root_Node model = new Root_Node();
wdcontext.nodeRoot_Node().bind(model);
In view, I set values for attr1 and attr2 using following code:
Ipublic<View>.IInput_node1Element ele = wdcontext.createInput_node1Element();
ele.setAttr1("<value>");
wdcontext.nodeInput_node1().addElement(ele);
Ipublic<View>.IInput_node2Element ele1 = wdcontext.createInput_node2Element();
ele1.setAttr2("<value>");
wdcontext.nodeInput_node2().addElement(ele);
But this code didnt work. Model was executed without data in this case.
So, i thought that these elements were created at view level only. And corresponding model objects were not created.
So, I have changed code like following way:
I have removed initialization code for Input_Node1 and Input_Node2 from view. Now, I am getting input values in two different value nodes. And before calling custom controller's method to execute model, I am making two ArrayLists and filling data in it. Now, i am passing these ArrayList objects as parameters to controller's method.
In this method, i am setting both values as follows:
wdcontext.currentRoot_NodeElement().modelObject().setInput_Node1(List1);
wdcontext.currentRoot_NodeElement().modelObject().setInput_Node2(List2);
Then i am executing my model.
But, When i am setting values for Input_Node1 and Input_Node2 as shown above, values are appended instead of overwritting the value. Because of this appended values, it gives mupltiple results.
Means, Both ways are not proper. What should be the proper and best way to pass values in this case?
Thanks,
Bhavik

Difference between value node,model node and recursion node?.

Hi all,
this is to ask you the difference between modal node, value node and recurrsion node?
please explain
Anhitya Kashyap

hi Anhit,
node can be classified as a value node or model node. The difference between value nodes and model nodes is that a value node can store the data itself, whereas the model node only references an external model object that stores the data.
more on nodes check this

How To Display attributes of Child Node and Parent Node in same view

Suppose I have two view Carview and CarDetail View...IN Component context I have Parent Node Called Cars and It have its attribute as Price,Warranty,Year and also One Child Node Called as Brand Name Whose attribute are PrimaryBrand and SecondaryBrand..Now If I do Mapping of My First View i.e CarView with Child node of BrandName..and then I Have To Show Whole Detail of Car in CarDetailView.......How Can I Achieve it..

Hi Vinay,
You can map the child node and even the paren tnode to the same view if u want to display in the same window..
If not if ur requirment is to dispaly in the sme view but should not map the child and parent to the Same view then you can take another new view.. and insert 2 view containers and then add the Child view and parent view in that view containers and then Diaplay the newly created view.

Lining up root node and child nodes in JTree

I have a JTree that has a root node and n child nodes. There are no sub-levels - it is structured just like AOL instant messenger. What I want to do is have the child node icons line up directly under the root nodes text. For example (if you can read this), where "-" denotes the icon:
- root
- child
- child
Currently it is something like this:
- root
- child
- child
I have been messing with the setLeftChildIndent( int ) and setRightChildIndent( int ), but they are not doing much...they seem to not want to only move the leaf nodes but all of the nodes, so its not doing exactly what I want.
Any ideas? In the meantime I'll be looking more into how exactly those indent mutators work.
Thanks!

What you want is to do a setRootVisible(false) on the JTree.
All your child nodes are then your "root level" folders.
tree.setRootVisible(true):
+root
+--child1
+--child2
+--child3
+----child3a
+----child3btree.setRootVisible(false):
+child1
+child2
+child3
+--child3a
+--child3b

Adding Node and Deleting Node in Tree

Hi,
I am building a tree dynamically.
I have a class which has set of properties.I am constructing as follows.
public class TreeNode
        public function TreeNode()
     public var friendlyName:String;
     public var icon:Class;
     [Bindable]
     public var children : Array;
     public var logicalName:String;
     public var neType:String;
     [Bindable]
     public var arrayColl:ArrayCollection = new ArrayCollection();
     public function addChild(node:TopoTreeNode):void
         if (this.children == null){
             this.children = new Array();
         children.push(node);
         arrayColl.source = children;
     public function clearChild():void
         children = null;
     public function removeChild(arrayIndex:int):void
         if(children != null)
         children.splice(arrayIndex,1);
         arrayColl.source = children;
Then I set the dataProvider as follows where treeModel is object that is injected.
<mx:Tree id="tree"
             dataProvider="{treeModel.rootNode.arrayColl}"
             labelFunction="{treeModel.getDisplayName}"
             iconFunction="{treeModel.setIcon}"
             width="100%"
             height="95%"
             rowCount="6"
             showScrollTips="true" showDataTips="true" dataTipFunction="{treeModel.getDisplayName}" allowMultipleSelection="true" click="treeModel.displayItemInWorkingView(tree.selectedItems);"/>
TreeModel has the following variables
        [Bindable]
        public var rootNode:TopoTreeNode = new TopoTreeNode(); // this is the rootNode.
        [Bindable]
        public var rootChild:TopoTreeNode = new TopoTreeNode(); // this is the child of the root node..
While constructing the tree, it is working fine.
But after this when i try to add a node (ie adding a node as child to rootNode), it is getting added to my rootNode object but it is not getting displayed
When i click on the items in the tree or click on the drop menu in the tree it is getting displayed.
But i want it to be shown in the tree without clicking anything.
Could anyone help on this?
Regards
Srini

Off the top of my head, you need to call a refresh of some sort, or executeBindings()... something like that.
You will also need to start at the root node and expand any parent branches down to the new leaf.
If you are still having trouble after looking into that, I can try and dig through some of old code and find my solution.

Move a node and sub-nodes in a hierarchyid

I have a hierarchyid that's roughly like this:
/1/...
/2/
I want to move /1/... so that it and all its children are below /2, so that the new hierarchy table looks like this
/2/1/....
I've followed this example
but it only moves the children of /1 and not /1 itself. I'd like to move /1 itself and all its children. I can't just specify / as the old parent, because that would include /2 and I'm sure it would chuck a huge wobbly anyway!
So, how can I move a node and it's children, and not just the children?
Thanks.

I found the correct example from Microsoft, and it has saved me from digging myself into a deeper hole (as I was, trying to mangle that other example to death!)

Associated nodes and Mutiple nodes type of property

I am looking for the difference between Associated Nodes, Multiple Nodes of property definition.
What I understood they both are different type of property using which we can associate multiple nodes to a node. But do all of them serve exactly the same purpose?
More importantly , after associating the nodes by using any of the property types, how we can access the property values of the associated nodes, be it for export purpose or exposing in DRM UI?
Is only way to get the associated nodes propety values is by taking the array constructed as value of mutiple node property and parsing it using the arary functions?
Do we not have any single function to get the node proerty values for the associated nodes?

Are you good, or is there more?

How to assign ALV for parent node and child node that uses supply method.?

HI Dear friends,
I need to display header details ( VBAK ) and Item details ( VBAP ). I have created two node like HEADER_NODE inside this i have created ITEM_NODE for this item node i use supply function 'GET_ITEMS' any way it is working only when crete two separate table and binding but when i come to work with ALV i am totally confused .. i have created two 'View Controller UI Elements' when i try to map HEADER_NODE it mapped properly but for ITEM_NODE it shows mapping already defined. return status message as 'Action Cancelled' . In result both ViewContainer shows only HEADER_NODE data only.
How to achive ALV for Parent, child node that uses supply function ? ?
Thank you

Delete Mapping is not enabled, that means there is no mapping done yet.
I just tried what you are saying and the application works and i am able to map the header table and item table and also again i could map the tables any number of times.. i didn't get any such message, sorry i couldn't recreate the scenario. might be there is something wrong in the context.
i just did it like this.
Please also move this to Web DynPro Discussion, Hope that would be helpful.
