Recursive Data types

Hi all,
There have been some threads about mapping of a message that has some recursive structures.
I am wondering how to define recursive structures.
Eg
<Persons>
 <Person>
 <Name>
 <Height>
 <Father>
 <Name>
 <Height>
 <Father>
 <Name>
 <Height>
 <Father>
Can someone please explain me?

Get image of Data Type of wire

Hello,
I know how to return the image of a front panel or diagram using VI server however I'm looking to be able to return the same image as displayed within the 'Data Type of Wire' information in the Context Help window when I hover my mouse over a wire. I thought this may be achieveable by returning a reference wire to a Front Panel Control and then maniulpate the methods/properties of that to try and return it but I can't find anything that will do the job. . .
Im asking because I have an object that stores another set of differenet objects and hovering over the highest most class returns a good diagram to show all of the data memebers within the system.
Any ideas on how to get programatic access to that image?
Cheers
Tom

I think you guys missed the point of the original poster.
When you hover over an LVclass wire, you see the content of the class cluster in the context help window. If the class includes other instances of other classes in its cluster, those classes are also displayed in the context help window.
Tom wants to get that picture. The problem is that what you're seeing is not a preset picture. It's probably a tree which is dynamically generated when you hover over the wire and is probably done in the C code with no visible interface in LabVIEW (definitely not a public one).
I can think of a couple of option:
1. The easy one is probably to programmatically open the CH window, position the mouse over a wire of your class (will require some access to private properties. Look at LAVA forums scripting forum to see how you can access these), and then capture the entire screen and cut out the part of the image which has the CH window.
2. The somewhat harder one is to rebuild this yourself. There's a class API in the LAVA forums code repository which should return the structure of the class. You can use that to recursively parse the cluster and build a tree of all the elements.
Why do you want to do this?

Binding of Tree to recursive data from web service

Hi,
I can't figure out how to bind a Tree component to recursive data from a web service.
I have a folders structure, where Folder consists of ID, label and array of subfolders (of type Folder).
Imported model structure shows that recursion, as I repeatedly expand class tree to arbitrary level.
However, when I try to create service controller for that web service, the recursive node for subFolders is not created - all that shows is ID and label. I was trying to create the recursive node in controller context manually, but it didn't work - the tree is still flat (with only first level visible), altough web service returns full tree with all levels.
How can I make it work? I was searching forums and Internet, but found only references to artificial example from documentation, where context data are created in code on web dynpro side.
Thanks for any help!

Questions on Merging Dis-similar Data Types...

I am using Web-I version 11.5.8.834 (We do not use the Crystal Reports module, all of our reports are built with Web-I).
I have two questions:
Question 1: First I am attempting to create a report from two different universes and need to merge a dimension from each universe. The two dimensions have similar data, but one is set up as a "string", and the other universe has the same data set up as a "number". Our IT department creates and maintains the universes and I have requested that one of the dimension data type be changed to match the other, but I am told that other users have already set up reports using these dimensions and to change them at this point might cause a problem with their reports. So my first question is: Can two separate dimensions be setup within a single universe, using the same data field, each having different data types (e.g., a field with numeric data be set up as a "string" and a second dimension be setup as a "number")? If this works, I can make a recommendation to our IT department to do this and I will not have to resort to Question 2. but just in case, here is Question 2:
Question 2: I have two other dimensions that I might be able to use, but it requires creating a variable and "trimming" data off of each of the fields. The first universe is a part number with three alpha characters followed by four numeric characters (PRT1234). The second universe has a serial number, in which the first four characters match the last four characters of the other universe (1234-00111). If I trim off the first three characters from the first universe using a variable (=right([Part_Number];4), and trim off the last six characters from the second universe using a variable (=left([Serial_Number],4), the variables will have matching data. The second question is: Can variables be merged? I've tried, but it isn't working so far. If so, can someone give me some hints on how to do it?

Edited by: Charles Norman on Aug 8, 2008 11:43 AM

Charles,
Can variables be merged?
No, local variables cannot be merged. The manipulation must be performed at the database level via Designer before the data comes across to the report. As an aside, your IT deparatment can create "new" objects just for you, placed in the list under a separate sub-class that manipulates the data to your liking and will not upset other users who already built reports using the original columns of data. I guess my point is that you can have multiple objects placed in your universe that derive from the same column in a given table -- user A has it per their flavor and user B has it per his flavor.
Thanks,
John

Error while transporting a data type

Hello all SAP PI Experts,
I'm trying to transport a data type but I'm getting the below mentioned error.
This is happening even when I gave the proper name of SWCV that contains this data type.
Please suggest how this problem can be solved.
Thanks,
Ajeya G V

Hi Ajeya,
An easy trick is to open the DataType on your Enterprise Service Builder, and once it is opened, (not edit, just open) go to Tools --Export Design Object
The correct SC will be filled as default.

What are the corresponding Data Types of some MDM Data Types

Hi Guys,
The MDM ABAP API involves creation of a DDIC structure in SRM. This structure should have the same fields with the MDM table fields. We would like to ask the corresponding ABAP Data Types for the following MDM Data Types.
MDM SRM
1. Look up (flat)
2. Look up (taxonomy)
3. Look up (heirarchy)
4. Look up (qualified flat look up)
Any significant inputs on this?
Thanks and regards,
RE

Hi,
Refer the below link. This is from the MDM Reference guide and contains the sample source code as well for almost all the things like creating repository, creating tables and fields etc. It would be helpful to you.

In the above wsdl the collection of fintObjInst if of type xs:anytype. From the wsdl, I do not see the xsd mapping for AccountIC which includes Name and Desc. Due to which, when invoking the web service from a different client like c#(by creating proxy business service), I am unable to set the parameters for AccountIC. I am using JAX-WS stack and WLS 10.3. I have already looked at blog http://weblogs.java.net/blog/kohlert/archive/2006/10/jaxws_and_type.html but unable to solve this issue. However, at run time using a tool like SoapUI, when this wsdl is imported, I am able to see all the params related to AccountIC class.
Can some one help me with this.
Thanks,
Sudha.

Did you try adding the the XmlSeeAlso annotation to the webservice
@XmlSeeAlso({<package.name>.AccountIC.class})
This will add the schema for the data type (AccountIC) to the WSDL.
Hope this helps.

Any idea what this errorr means? the data type of the reference does not match the data type of the variable

I am using Veristand 2014, Scan Engine and EtherCat Custom Device. I have not had this error before, but I was trying to deploy my System Definition File (run) to the Target (cRio 9024 with 6 modules) and it failed. It wouldn't even try to communicate with the target. I get the 'connection refused' error.
I created a new Veristand project
I added the Scan Engine and EtherCat custom device.
I changed the IP address and auto-detected my modules
i noticed tat Veristand didn't find one of my modules that was there earlier. (this week)
So, i went to NiMax to make sure software was installed and even reinstalled Scan Engine and Veristand just to make sure.
Now, it finds the module, but when i go to deploy it getsto the last step of deploying the code to the target, and then it fails.
Any thoughts?

Can you deploy if you only have the two 9401 modules in the chassis (no other modules) and in the sysdef? I meant to ask if you could attach your system definition file to the forum post so we can see it as well (sorry for the confusion).
Are you using any of the specialty configurations for the 9401 modules? (ex: counter, PWM, quadrature, etc)
You will probably want to post this on the support page for the Scan Engine/EtherCAT Custom Device: https://decibel.ni.com/content/thread/8671
Custom devices aren't officially supported by NI, so technical questions and issues are handled on the above page.

Need to determine data type of free characteristic in multiprovider

Hi,
I need to determine the data type (e.g. numeric vs alpha numberic) of a free characteristic in a multiprovider. Can this be accomplished in BEx Query Designer?
If not, can it be accomplished in RSA1? How?
Thanks,
Kevin

its not possible via Query designer..
give that object name if it is infoobject then you can get via RSD1

IDOC - XI - IDOC scenario. I can't import XSD to Data Type

Helo!
I have some problem with creating data tape. I have to create data type similar to IDOC structure which i imported from SAP system. Similar becouse in this DT I need to add some more elements. Becouse the IDOC structure is large I wont to import IDOC structure to this DT automaticly. I try to eksport XSD structure of my IDOC and then import to data type but i can read the monit:
The tag <element> is not allowed at <<xsd:schema><xsd:element><xsd:element>>.
I'm beginer in XSD so I don't now how to change this file.
Can somebody help me on that or explain whot I can do to make this DT.
Thanks for answer!

Hi,
U can import the IDoc XSD to External defination and use it in your Message Mapping and Interfacing Mapping.
There is no need to create a data type of message type for IDoc.
External Defination
External Definition enables you to import a local WSDL, XSD, or DTD file to the Integration Repository and specify which parts of the schema to be used as a description for a message.
U can use this ED as
1.Inbound/Outbound in the Message Interface.
2.Source/Target structure for the Message Mapping.
In a scenario If there is a necessitity for changing the Occurance of some segment of the IDOC steps u perform is.
1.Import the IDoc to XI.
2.Export the IDoc(i.e XSD format) and save it to the local machine.
3.Make changes to the IDoc structure by modifying the XSD file in the local machine.
4.Save it as an XSD file Itself.
5.Import the XSD file in the IR under the External Defination.
6.Use this XSD in your Message Interface/Mapping which is same as IDoc structure but with some changes that u have made.
Go Thru this Blog <a href="/people/michal.krawczyk2/blog/2005/12/04/xi-idoc-bundling--the-trick-with-the-occurance-change Bundling - Trick without BPM</a> BY Michal Krawczyk where the Occurance of the IDoc is changed to 1...Unbounded from 1...999999999 by using the XSD.

SharePoint 2013 List - Multiple Data Types in the Same List

In the same SharePoint 2013 list in Data Sheet View, I want to have one column where my end users enter inputs for KPIs. There are 3 groups of KPIs (A, B and C) and they each have different data types (A-string, B-decimal, C-percentage) and I want to be
able to base their input options off of the KPI type
Does anyone have any suggestions on how I can leverage my parent-child relationships so when an end user...
1. Picks KPI type A, they can select from a choice filed (Green, Yellow, Red)
2. Picks KPI Type B, they can enter a decimal (-1.000 to 2.000)
3. Picks KPI Type C, they can enter a percentage (-100.00% to 100.00%
I'm using if I want to keep this in one list, one column and in data sheet view that the out of the box solutions won't meet my requirements. I was looking at some solutions from Bamboo (Lookup Selector Column) but don't think that applies here.
Thanks!
Johnny

Hi Johnny, you can accomplish this using cascading lookups in InfoPath if that program is available to you. Otherwise, if you want a 3rd party product, we use the Kwiz cascading lookup and it's worked wonders for us:

Dear All,
We are building Meta data in planning using HAL 9.2 ...while construction of accounts we were able to assign "Currency" Data Type ,but were unable to add the "Non Currency" data types to account members.
We have mentioned "Non Currency" in the the Data Type Field.
Thanks in Advance.

Hi Guys my issue is resolved..... just wanted to let you know that you will need to write "Non-Currency" in the field name in the csv for marking accounts as Non currency data type.

my problem is, for each job_id there is many users. Oh that's something completlty different...
I Strongly Recommand to_

2.*create a relation between them* 1 to many to get for each job more than a user that's the way that Must be -- execuse me the bad design of the db pulled u into this trap -
3.then u can deal with it normally no need to a sample code but just a form with Jobs as (Master) and Users as (detail) with a relation and with a simple query u can display each job_id is for many users.
no null values no commas r needed.
Hope this helps...

JDBC MS Access--- cannot extract entry with null value with data type Meta

I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexception

The question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception.
