Recursive node error in ESR

Check result for Data Type: PriceDerivationType | http://alfuttaim.com/xi/storeConnectivity:
Data type Data Type PriceDerivationType | http://alfuttaim.com/xi/storeConnectivity points to itself
Hi Experts ,
I have a datatype part of sap standard content which has a recursive node ( poniting to itself).
I have to copy it to a local name space and use it . When i try to copy it and activate it i am getting this
error .
"Check result for Data Type: PriceDerivationType | http://alfuttaim.com/xi/storeConnectivity:
Data type Data Type PriceDerivationType | http://alfuttaim.com/xi/storeConnectivity points to itself"
Please let me know how do i go abt activating this object.
Thanks in advance and best regards,
Anil

Hi Anil,
When you copy it local namespace, verify the namespace is local or the one which is poiting to itself.
If this is pointing itself, manually you change the namespace which you want and activate it.
Hope this helps.

Recursive node in xsd

Hello PI people.
I have a problem reguarding to a XSD file (standard DSML found here: [DSMLv2|http://www.oasis-open.org/committees/dsml/docs/DSMLv2.xsd]).
When I Import it as external definition to PI Integration builder it all works fine but if I undfold the message "Filter" the there is problem with the defintions for "not" and after one more fold on "and" or "or" the same problem is shown. It looks like PI understands the XSD but it just not permit recursive nodes?
Is it the XSD that dosent meet the PI standard or is it a internal thing in PI that needs to be activated to handle recursive nodes i XSD?
(When a message is mapped with this DSML all the error prone nodes are stripped..)
// Jesper

Hello Jesper,
You can refer to this document for supported XSD and WSDL:
http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/00a9a425-1769-2a10-9196-bd8eeed72e4c
Once you open this excel document go to row 94 for Recursive Data Structures, it says it is supported but there is a reference to row 143 which says
Recursive data structure must be expanded in design-time manually to the desired depth
If what you are thinking is dynamic recursion, then it is not possible. You have to use Java Mapping/XSLT for that. Now as for the nodes not displaying, right-click on the node and then select expand recursive structure.
Hope this helps,
Mark

Recursive Node In WebDyn Pro

Hi........
Like I am not Able to Create Recursive Node. it is giving Error. Type Comfortable.
Please Tell Me solution ...

You may have to explain lot more than this,so that we can understand and help you effective.
What you do exactly? from where you are trying to do ? explain it in step step what you have done so for and also post the exact message.
You must be making somewhere a mistake. This is not a kind of error i hear often.

[Tree] item and node order ! (Recursive Node)

I made a wd4a has organizatonal structure tree. but I have some problem with the org tree.
I want to have a tree(org structure) in item(person) and node(organization) order.
Root                                            Root
|- Person 1                                    |- Head Dept
|- Person 2                                    |        |-Person 3
|-Head Dept                        ->        |        |-Person 4
|       |- Person 3                             |-Sales
|       |- Person 4                             |- Person 1
|-Sales                                          |- Person 2
( to be displayed)                                 (current displayed)
Whiat's the problem?
Although the both of them have a same contents, I really want to display in person and org order .
Plz. help.

I solved this problem myself and it makes me very so tired.
I guess that Recursive node tree have some bugs.
If a node have one recursive node and one sub-node and some kinds of attributes,
we have to make a decision on how to display and sort them(sub-node and attributes)
There is a example below as I really want to sort them.
C_Drive Folder
- file 1
- file 2
- Folder 1
- file3
- Folder 1-1
- Folder 2
Context
    |-Folder Node
    |      |-File Node
    |      |       |-File Name attribute
    |      |-Folder Name attribute
    |      |-Folder_Content             -> Recursive Node
When you meet this situation,you must implement the context nodes and
the names of context node and recursive node must be in alphabet order you want to display.
I am sorry for my crumsy writting English.

Internal error in R-tree processing: [Recursive fetch error]

Hello,
I seem to be getting an error when using any type of SDO function (SDO_RELATE, SDO_FILTER, SDO_ NN, ... ) on my spatially indexed data. The error I'm getting is this:
ERROR at line 1:
ORA-29903: error in executing ODCIIndexFetch() routine
ORA-13236: internal error in R-tree processing: []
ORA-13236: internal error in R-tree processing: [Recursive fetch error]
The interesting part of this is that I only get this error if I insert more than 31 entries into the table. All the relevant code is posted below, what I do is create the table, then create the metadata from the sqlplus interface. After that I run a java program that does Clear() then Insert() then Create_Indices(). All these run just fine (at least run without telling me about any errors). But as soon as that is all done and I do an SDO query on the data, for example:
SELECT location stop_range_poly_area
FROM stops
WHERE SDO_FILTER
location,
SDO_GEOMETRY
2003, null, null,
SDO_ELEM_INFO_ARRAY(1,1003,1),
SDO_ORDINATE_ARRAY(300,300, 600,300, 600,600, 300,600, 300,300)
) = 'TRUE';
I get the above mentioned error. But if I change my data so that it doesn't have more than 31 entries (doesn't matter which 31 entries, just so long as it doesn't exceed that number) that query (and all of my other SDO test queries on the stops table) seems to work just fine.
Thanks for looking at this,
Brad

Hi,
Thanks for trying but changing those items for the specific failing queries didn't seem to help. Though you do seem to be right about the internal/external polygon problem, so I changed it all my other queries to see if they would fail (that way things would at least be consistent), but it doesn't seem to make a difference. All my old failing quries still fail and my working ones still work. I also changed the co-ordinates as you specified and still have no changes (unless of course the results changed, but right now I'm just looking for queries that compile and run, the results don't matter yet).
Maybe this will help, I'll give you guys both sets of data, one that works and one that doesn't and maybe you can see a problem in the data that I'm just missing or too ignorant to see. The data is simply comma seperated values that I parse into the required fields in the order (id, description, x, y).
So far, the only reason I've been able to find that the non-working data doesn't work is because there are more than 31 rows. I started taking records out of the stops table in a binary search sort of pattern. If I take out stops 100-115 (resulting 29 records) all the queries work, if I take out stops 100-107 (resulting in 36 records) it doesn't work. If I take out 109-115 (resulting in 35 records) it doesn't work. If I take out 1-11 (resulting in 32 records) it doesn't work. If I take out 1-12 (resulting in 31 records) it does work. Here's a table
Take out Stops ---- records left -- Works?
s1-s11 ------------ 32 ------------ No
s1-s12 ------------ 31 ------------ Yes
s100-s115 --------- 29 ------------ Yes
s100-s107 --------- 36 ------------ No
s109-s115 --------- 35 ------------ No

Brad

How to get current node element for recursive node.

Hello Xperts,
I have a requirement where I need to find the current node element of the recursive node.
I was trying following code for the same
Data:
selected_elem type ref to if_wd_context_element.
selected_elem = WDEVENT->GET_CONTEXT_ELEMENT( NAME = 'CONTEXT_ELEMENT' ).
selected_elem ->get_static_attributes(
    IMPORTING
      static_attributes = sel_attri ).
But it does not work for me and I always get 1st node value.
Please help me in this issue.
-Ashutosh

Hello ,
         If you implementing a simple tree ( not table tree ) and you want the selected element for
OnLoadChildren event .
Then create an importing parameter CONTEXT_ELEMENT of type IF_WD_CONTEXT_ELEMENT
in the event handler of onLoadChildren .
Webdynpro framework automatically filled up the context element with the current node in the tree .
I tried it , It really worked for me .
If you have a table tree then you need to create an importing parameter PATH of type String in tha event handler .
Webdynpro frame automatically fills the PATH .
the use can use the following method to get the element from the PATH .
wd_context->path_get_element( path ).
I tried it , It also worked for me .
Regards
Vivek
PS : please provide the points if answer is helpful .

Reading and modifying data in a recursive node

Hi All,
I am using a TreeByNesting column in a table UI element of my component.
For this purpose I have created a node in the context - ('TREE') which contains a recursive node - ('RECURSIVE_TREE').
What would be the simplest way to read the data from this node ? And how do I go about changing a single line of information
within the node ?
Thanks,
Fathima

What would be the simplest way to read the data from this node?
Reading data from a recursive node is no different to reading any normal node. It's just that you have a very simple way of holding the same structure.
Once you have a reference to the element of a node (a single line of data), then updating it is no different to updating a line of a table.
More issues are associated with making and setting lead selections for an element (all parent elements also need to be lead selected and no child elements). Searching through the hierarchy, etc.
Where I have used this functionality I have often set up search tables with the key data that I want to search in a flat table and a reference to the corresponding element - much easier to search then - without having to resort to recursive coding!
Could you elaborate a little on what exactly you are having an issue with?
Cheers,
Chris

WD ABAP: Lead selection on a recursive node

Hi,
I would like to know if lead selection is permitted on a recursive node in WD ABAP.
As of now, methods 'set_lead_selection_index' or 'set_lead_selection' do not cause lead selection to change in my view, and the lead selection rests only with the first row in my table..(I have set the rowSelectable property to YES for my table.)
Also, method call 'set_selected' performed on my target element does not solve the problem.
Any help much appreciated!
Best Regards.

Hi Adithya,
Yes, you can have a leadSelection on a recursive node and it can be changed by the same methods that are used for non-recursive ones.
Best regards,
Thomas

WD ABAP: Recursion Nodes that Repeat Tree Nodes with Embedded Tables ???

At Rich H's suggestion, I'm posting this here as well as in the blogs.
Suppose you've got a tree context with a node that has a table embedded under it. (For example, the TREE_WITH_TABLE view of WDR_TEST_EVNT has this kind of context substructure.) Call this node "NODE_WITH_TABLE."
You now define a recursion node underneath "NODE_WITH_TABLE" and specify "NODE_WITH_TABLE" as the repeated node for this recursion node. Call this recurion node "RECURSION_NODE".
Lo and behold - the table fills properly when you're on any instance of "NODE_WITH_TABLE", but not when you're on an instance of "RECURSION_NODE".
I'm hoping that:
a) I'm doing something wrong;
OR
b) There's an easy work-around/alternative I'm not seeing
OR
c) SAP will give recursion nodes enough memory to carry any table(s) embedded in the nodes they're repeating.
'Cause I sure don't want to have to define "n" levels of tree-nodes that have different copies of the same table(s) embedded in them.

Maybe you might want to back out your weblog as it is not really a place to ask these types of questions. Think of it this way, if you are allowed to do this type of weblog, what is stopping any other weblogger. Hence the weblogs would just be another forum, which I don't think anyone wants.

I've written a program to control the angular position by using PID control algorithm.
The program works fine but after certain amount of time. The system hanged and need to shut down the LabVIEW and restart.
The warning message pop up is showing in the attached file.
One more question, is it the PCI-6221 M-series card can used for real-time application.
Just for your information, I'm using:
- LabVIEW 7.1
- PCI-6035E
The program is attached to the message "Call Library node error [2]"

Recursive node and Non Recursive node

Hi,
What is the difference between Recursive node and Non Recursive node ?
Thanks,
Teja

Hi Teja
Recursive node
If you wish to represent a recursive data structure within the context, a recursive node is the correct node to use. The simplest example of recursive data within a hierarchical structure is a file system. A dictionary can contain either files or subdirectories. This definition is then repeated for each subdirectory level down the hierarchy.
Within the context, a recursive node is a special node that has only two properties: name and repeatedNode. As with any context node, a recursive node must itself name, but the repeatedNode property is where the recursion is defined. This property holds a reference to some parent node and indicates that, at runtime, the location of the recursive node will be occupied by a node of the type indicated in the repeatedNode property.
You should think of a recursive node as a design time placeholder used to indicate a node will be created at this location at runtime, and will be of the type named in the repeatedNode property.
The node name identified by repeatedNode must lie on the direct path back to the context root node.
When a recursive node is created at runtime it always created as a non-singleton node. This is a hard-coded feature and cannot be changed.
Non recursive node is opposite to recursive node

Ruturaj

Hi
Recursive Node is used when depth of child nodes under a given context while not be known untill at runtime.
Recursive Node have two properties : Name and repeated Node
