Problem of getting user defined element

Hello collegues !
I have following problem
I need to check, if my element was creanted on form or not
For this i do following :
if(oOrderForm.Items.Item("myItem")!=null)
but this give me an exception
are there another ways to check, if element exists or was not created yet ?
Best regards

there are two ways:
1. clear way
dim oitem as sapbouicom.item
for each oitem in oOrderForm.Items
..check the item id
next
or
2. quick way
try
dim oitem as sapbouicom.item
oitem = oOrderForm.Items.Item("myItem")
catch ex as exception
... doesnt exists
end try

Using a user-defined element in ASO cube.

I have an ASO cube to which I'm adding a new hierarchy/dim containing a single user-defined element as a member. This dim is set to dynamic at dimension level, since I'm going to add additional members with formulas.
My issue is that as soon as I add this new hierarchy to my cube, all my fact values double! What could cause this and how should I fix this? The user-defined element in this new dim is not connect to the rest of my data in any way, i.e. it is not in any table of my minischema. So why should it have any impact on my data values? Should I be adding a filter of some kind on this user-defined element?
Fyi- I'm using Essbase Studio (EPM 11.1.2) for cube building and data loading.
Appreciate any help.
thanks,
Axe

A colleague suggested a reason that SDO_GEOMETRY works is that it is granted to PUBLIC with GRANT OPTION. PUBLIC is not a proper role, somewhere between a user and a role and the issue of having to receive permissions on the type explicitly do not apply.
If I GRANT EXECUTE ON XTYPE TO PUBLIC WITH GRANT OPTION; it works!
Thanks for the replies.

Problem with the user-defined message search in PI 7.3.1

Hi, all
I having been trying out the new user-defined message search in PI 7.3.1(with TREX). I am stuck on creating the search critera section and could not move forward. Here is how I define the filter:
Here is a sample payload:
<?xml version="1.0" encoding="utf-8" ?>
<ns:JOB_MT xmlns:ns="urn:peoplesoft:batch:job_r:message">
    <MsgData>
      <JOB>
         <ACTION_FLAG>NewPerson</ACTION_FLAG>
         <EMPLID>XXXXX</EMPLID>
         <REG_NO />
         <LAST_NAME>XXXX</LAST_NAME>
         <FIRST_NAME>XXXX</FIRST_NAME>
      </JOB>
    </MsgData>
</ns:JOB_MT>
I have tried the xpatch search criteria as the following:
/ns:JOB_MT/MsgData/JOB/EMPLID
/ns:JOB_MT xmlns:ns="urn:peoplesoft:batch:job_r:message"/MsgData/JOB/EMPLID
Both failed to return the emplid field when I clicked on the "test search criteria" against a PI message. Can you advise what I did wrong?
Thanks,
Jonathan.

Problem after uploading user defined characterstic schema in product catalo

Hi friends,
We were using SRM 5.0 and CCM 2.0, we were uploaded Master catalog through .CSV file, Product catalog schema through .XML and user defined characteristic schema through .XML file separately. System given message catalog updated successfully. But when I observed in product catalog user defined characteristics are removed from the product catalog the content of these fields is also wiped out from the items. Once the catalog was in this state, I mapped it to the Master Catalog and all the user defined characteristics show up in error. What could be the cause?? can any body Help (Urgent)
Thanks in advance

Problems with getting user input

Hi All,
I want to get user input from a command line and i am NOT using a GUI.
The user can still see their password when they are typing it in.
Is there anyway to show '******' when they type in their password??
This is what I have so far..
public static void getPassword() {
System.out.print("Enter password-->");
DataInputStream input = new DataInputStream(System.in);
try{
password = input.readLine();
catch (IOException e){
System.out.println("ERROR " + e);
Any help would be greatly appreciated.
Thanks
Kal.

Kal,
I'm pretty sure you're going to need some kind of GUI (either a Java window or an HTML page) to get the desired effect. There might be a way to set the echo character in the command line, but I'm not sure.

How to get user defined class in java client of a bpel prcoess?

I have written a simple bpel process which returns a bean class namely employee which has three String fields(name,id and email). From java client when I am invoking the prcoess the prcoess instance is starting and completing properly. From Bpel console when I check the audit of the instance, it shows everything as expected. But in client class instead of three strings I am getting only first string i.e email in response. I checked the mapping and all WSDL files but could not find a proper reason. I am attaching the wsdls of bpel prcoess and the client code:

Hi Abdul,
From the document, we know that CONSTRAINED flag is used to reduce the risk of injection attacks via the specified string. If a string is provided that is not directly resolvable to qualified
or unqualified member names, the following error appears: "The restrictions imposed by the CONSTRAINED flag in the STRTOSET function were violated."
So you need to make sure the members are passed properly to the STRTOSET function. For more details, please see the following links:
http://ch1n2.wordpress.com/2010/02/21/the-restrictions-imposed-by-the-constrained-flag-in-the-strtoset-function-were-violated/
http://www.bp-msbi.com/2010/04/passing-unconstrained-set-and-member-parameters-between-reports-in-reporting-services/
Hope this helps.
Thanks,

Hello,
It is possible to create user fields using SDK on anykind of table but, sometimes in some Tables, adding them causes integrity problems and B1 cannot create the document of the Table, you can try that, but if there's an error when adding the bank statement you should erase it from the OBNK table using SDK again.
I've tried this on MRV1 (Inventory Revaluation Lines) and IPF2 (Landed Costs, Costs), when I tried to add the document (Inventory Revaluation or Landed Costs) appeared an error and B1 could not create the document, so i had to remove them with SDK again and the error was solved.
Best Regards hope it'll help you

Problem with creating User Defined Fields

Hello,
I have a big problem on one customers db. Everytime when user logs in SBO, he got immediatley after login message, that db structure was modified and user must click OK to continue (close all form - in this case is still no form opened).
I tried to uninstall all addons to be sure that its not addon related but when is only clean SBO there, the message still pops up. It seems that somewhere in db is stored that this message must pops up.
When I copied this db localy from custromer, the message still occurs.
Is here someone who met this prolem and solved it?
Thanks
Petr

Hi Petr,
Just to remind that if you send a message to SAP based on Suda's answer belows:
Petr,
This is very unusual, Please check SAP Notes and also send a message to support. This should not be happening.
Madhan: Just FYI - Petr is one of the Senior Implementation and SDK consultants who has spent a long time on the product and I am 100% sure that he knows the basics you are pointing to very well.
Suda
you must really make sure that you have performed support level 1 and level 2. If not, the SAP support will be happy to bill the message about 80 euro.
Rgds,

How do you have JList display user defined element

How do you have JList display the element you define???
I tried:
list.setSelectedIndex( 1 );
list.ensureIndexIsVisible(1);
because I want the element at index[1] in the list to be displayed when the GUI opens. It always defaults to element [0] (1st element).
So if I have
String[] colors = {blue, red, yellow};
when the GUI opens, I want "red" to appear in the JList, but blue is always displayed...

Sorry, that must've been cut off, here it is...
What I want it to do is open and I want "green" to be the only element showing in the JList...

Problem related with User Defined search

Hi all,
In service type marketing doc.i added three UDF at row level.
1)Item code
2)Item Desc.
3)Quantity
i need to design a formatted search which will multiply Quantity with unit price and will update result in Total field in row level.
please suggest me Formatted search.
TIA

Chetan,
In addition to Suda's reply, we have also created 3 UDFs in the service type document of purchase order but there is no item code. it is okay you use item code UDF but actually it won't give effect if you use the 3 udfs in the purchase or sales order documents, although actually we assigned the following FMS I will give. Why I said this because user always asks how to make automatic movement of 3 UDFs to the next documents (GRPO service and A/P invoice service). I suggest to assign the 3 UDFs you made to invoice directly.
Try to use this another code to make Total (LC) become automatic update after you fill the qty and unit price;
declare @m as money
declare @n as nvarchar(40)
declare @o as varchar(40)
declare @p as money
declare @q as varchar(40)
declare @r as money
declare @total as money
declare @ntotal as varchar(40)
set @n = $[$39.5.0]
set @n = substring(@n,4,(len(@n)))
set @m = cast(@n as money)
set @o = $[$39.U_QTY.0]
set @p = cast(@o as money)
set @total=@m*@p
set @ntotal=cast(@total as nvarchar(40))
select @ntotal
Assigned the query FMS above using display saved values.
You just need to replace this following:
$[$39.U_QTY.0]
to be UDF code of quantity you have made
Rgds,

Problem when getting array's elements in JSF

Using Struts/EJB/JSF.
Here is the code:
Action servlets code:
request.setAttribute("colSellers", (List<SellerDTO>) List );JSF part:
<c:out value="${colSellers[projectForm.client].id}"/>Error message:
*[ServletException in:/html/forms/project/read.jsp] The "[]" operator was supplied with an index value of type "java.lang.String" to be applied to a List or array, but that value cannot be converted to an integer.'*
But it works when i use real integer values....like
<c:out value="${colSellers['2'].id}"/>

Sorry, but this doesn't look like JSF, it looks like a combination of servlets, JSP EL and JSF. It will all work alot better if you choose your poison.
Put the array in a managed bean and use a JSF component like h:datagrid or t:datalist to display the elements. If that seems too restrictive, do what I did and switch to Spring MVC.

Problems using user defined activitys in Process Flows

Hi everybody,
i have problems using an user defined activity in my owb process flow.
I did the following according to https://blogs.oracle.com/warehousebuilder/entry/how_to_use_user_defined_activity_in_owb_process_flow.
1. create a script in /tmp called test.sh
2. chmod +x on the script so it can be executed
3. Changed the Runtime.properties file under ORACLE_HOME/owb/bin/admin
property.RuntimePlatform.0.NativeExecution.FTP.security_constraint = NATIVE_JAVA
property.RuntimePlatform.0.NativeExecution.Shell.security_constraint = NATIVE_JAVA
property.RuntimePlatform.0.NativeExecution.SQLPlus.security_constraint = NATIVE_JAVA
property.RuntimePlatform.0.NativeExecution.OMBPlus.security_constraint = NATIVE_JAVA
4. Creating an Process Flow with just the user defined activity
5. Deploying the Process flow was successfull
But everytime i execute the pf i get the following error in my Job Details.
TEST_PF:USER_DEFINED
Parameters
Log file is available. Click Information button to view.
It says Log file is available. But i can't find this file. Also i don't know what the problem is.
Can anybody help me out of this?
Thanks a lot

Hi,
solved the problem by myself.
I had problems with my script. So i insert set -x into the script an executed the pf again. Know i can see whats happening in a log. You can find this log in the job detail window by pressing the blue ! Button when the whole PF (the first entry) is marked.
Greetings

User Defined Field Print Layout Designer print problem

I am having a problem with a user defined field in the Business Partner - Addresses table. The user defined field is a "directions" text field that is intended to print on packing slips generated from the sales order. When I use the PLD to add the UDF in the header or in the table, all data lines in the body of the report repeat.
Please advise if others are seeing this and what work around or SAP plans exist to resolve.

Hi Glen,
I am facing the same problem.
I need to add UDFs in Business Partners - Addresses at row level. The field will be used for some Taxation Nos. like CST, LST, VAT. I have tried to add. the fields are added and data saved too.
But when I am going to PLD of Invoice and tried to get, the Business Partners - Addresses Table not showing in the list.
Shell I have your help to resolve this.
Thanks a lot.
With Warm Regards,

Oracle 11g AQ : problem enqueue user-defined type with varchar2 attribute

Hello.
I have a problem enqueuing a user-defined type to the queue on Oracle 10g.
I'm using jdbc driver (ojdbc5.jar, version 11.1.0.6.0) as they provide oracle.jdbc.aq package.
The type is following:
CREATE OR REPLACE TYPE FIXED_T5 AS OBJECT
(id integer,
label varchar2(100),
code integer,
today date
)I have created a java class for this type with jpub utility supplied with oracle 11g client package:
jpub -user=scott/tger -url=jdbc:oracle:thin:@host:sid-sql=FIXED_T5:ru.invito.FixedType -compile=falseIt generated FixedType.java and FixedTypeRef.java files. Don't understand why i need the latter (FixedTypeRef).
Then in test app:

Could anyone tell me what is wrong with the setup/code?
Why 'label' not saved in queue, though i saw it is not empty in STRUCT?

Thank you for the reply!

FixedType data = new FixedType();
// hack: proper initialization for 'label' field
data._struct.setNChar(1);
data.setId(ID);
data.setLabel(label);
data.setCode(1);
Date today = new Date();
data.setToday(new Timestamp(today.getTime()));
Datum d = data.toDatum(connection);
STRUCT s = (STRUCT) d;
logger.debug(s + ".debugString(): " + s.debugString());
logger.debug(s + ".dump(): " + s.dump());and if i comment line (data._struct.setNChar(1);) the debug messages for created STRUCT also shows empty value for label.
But if i explicitly call data._struct.setNChar(1) then debug contains the label i defined in call to the setLabel method.
