User Define Function issue

Hi all
 i am doing Idoc to file Scenario.my problem is in message mapping..
sometime at (IDOC) source one segment get repeated 2 times.
like
 E1IDPUK2 (a,b,c)
 E1IDPUK2 (a,b,c)... but i want the particularfield value which comes from 2nd segment..in above case take "a".
the segment occurances can be 2....many.. and so want the particular field value from last segment
the particular field (ex="a") is populated for every repetition of segment but i want
the last repeated segment ,"a" field value...
can any body share me the java code...
note : a,b,c are taken as example fields of the segment.
Thanks & Regards,
Ajay..

Hi,
it's pretty easy:
you need to use UDF of type queue
inside it:
check how many segment are there
and choose the last one
and you will have this field
I also presented such mapping exercises (with E1EDKA1 - partner segment) in my book:

User Defined Function Issue with Inbound Node

Hello Guys,
I have some doubts to do the some code with a UDF.
I do a call to an RFC to get some data of R/3 from PI. In the return I have:
<item>
<field1>
<field2>
</item>
The item is 0 to unbounded, and I have to do a loop at the item and take the values of field1 and field2 of the last item.
I have created a UDF with context queue, but how can I take the values
It is correct if I have?
public void calculate(String[] var1, ResultList result, Container container) throws StreamTransformationException
String a = "";
String b = "";
String result = "";
for ( int i = 0; i < var1.length; i++ )
 a = var1.??
 b = var1.??
if ( a.equals( '' ) and b.equals( 'DELE' ) )
 result = a.
else
 result = "";
 result.addValue ( result)
I want to take the values of the las item for field1 and field2 in strings a and b, and after do a check of the values to put the result.
What I don't know hot to do is to take these values.
Could you help me please?
Many thanks in advance.
Regards,
Xavi.

Use removeContext just after the RFC lookup result & before the UDF. That would give you all the field values( field1 & field2) values in one context. Then use this UDF:
for(i=0;i<var1.length;i++)
if(i = var1.length - 1)
 result.addValue(var1 ) ;
Use this same UDF for both the fields seperately.
Hope it helps.

User Defined Function Error - Can't find function

Hi All,
Version: 11.1.1.4
I created a user defined function and added it to one of my BPEL Processes. I can see the function in JDeveloper and can compile the project without issue. We placed the jar file out on the SOA Server following the oracle user defined function examples. After placing the file out on weblogic I was able to successfully deploy the project.
Oracle Deployment Steps:
To deploy user-defined functions to runtime:
1. Copy the user-defined function JAR files to BEA_Home/user_projects/domains/domain_name/lib or a subdirectory of lib. Where domain_name is the name of the Oracle WebLogic Server domain (for example, soainfra).
2. Restart the Oracle WebLogic Server.However, when I try to run the composite application I get the below error. I am not really sure why it can't find the Function? The jar is out on the server and the jar was added to the project?
Error:
Non Recoverable System Fault :
<bpelFault><faultType>0</faultType><subLanguageExecutionFault xmlns="http://schemas.oracle.com/bpel/extension"><part name="summary"><summary>XPath expression failed to execute.

Check the detailed root cause described in the exception message text and verify that the XPath query is correct. </summary></part><part name="code"><code>XPathExecutionError</code></part></subLanguageExecutionFault></bpelFault>Any suggestions would be greatly appreciated!
Thanks,

try putting the jar location explicitly in weblogic server's classpath i.e. add BEA_Home/user_projects/domains/domain_name/lib to wls classpath and restart server.

Error Using imported .JAR in user-defined function

Hi All,
I am trying to use jar files provided to me in user defined function as follows:
DataEncryption temp = new DataEncryption();
String ret = new String();
ret = temp.getEncryptedData(a);
return ret;
All jar files working perfectly in java software, But when i am trying to test the mappings by using above user-defined function.
I am catching the error and put in target field then, I am getting following message in target field:
"An error occured in getEncryptedData method : java.lang.SecurityException: The provider SunJCE may not be signed by a trusted party"
Please help in finding the error.
Regards

Check if the XI Server JRE is the same as the client machine on which you have compiled your JAR.
1.4 has had this issue and i remember seeing it in a few forums.The problem should not occure in 1.5

BUG in DB XML? (when dealing with modules, user-defined functions)

Hi,
this post can be related to Different results for the semantically the same queries but here examples are even simpler.
I have the module with one user-defined function:
module namespace tnt = "http://tntbase.mathweb.org/ns";
declare function tnt:filter-path($docs as document-node()*, $path as xs:string) as document-node()*{
$docs[dbxml:metadata('tnt:path') = $path]
};Then I have a query:
import module namespace tnt = 'http://tntbase.mathweb.org/ns' at 'file:/path/to/module/user-func.xq';
(: this variable is IMPORTANT in the query:)
declare variable $len := 3;
(: here goes the same function as in the module, but with different name :)
declare function tnt:filter-path2($docs as document-node()*, $path as xs:string) as document-node()*{
$docs[dbxml:metadata('tnt:path') = $path]
(:the query itself :)
tnt:filter-path(collection("xml_content.dbxml"), substring("a:/doc.xml", $len)) If I execute the query I get *0* results, if I use function tnt:filter-path2 (instead of module's tnt:filter-path) then I get the expected *1* result.
Also I experimented a bit with a query and got the following observations (independent from each other):
1) If I substitute $len by value *3* or *3.0*, then I get right results in both cases, i.e. if the query itself looks:
tnt:filter-path(collection("xml_content.dbxml"), substring("a:/doc.xml", 3)) 2) If I change the module's function so that it uses value comparison instead of general comparison, then I get the right results in both cases as well:
module namespace tnt = "http://tntbase.mathweb.org/ns";
declare function tnt:filter-path($docs as document-node()*, $path as xs:string) as document-node()*{
$docs[dbxml:metadata('tnt:path') eq $path]
};Please, help me out! I'm pretty sure it's a problem of DB XML and I'm struggling with it for a long time in this or that shape.
Thanks a lot in advance,
Vyacheslav

I upgraded from 2.5.13 to 2.5.16 and the bug disappeared. The reason why I didn't do it before was that I hadn't seen any relevant for me fixes in the release notes of 2.5.16 comparing to 2.4.13 (Actually I already have had two patches for two relevant issues in the 2.5.13 version)
Sorry for the false alarm.

User defined function to set a default value of a column

Hi All
Can we use user defined function to set a default value of a column ??
for example:
create or replace function test1 return number is
begin
return 10;
end;
create table testt
(id as test1,
name varchar2(20));
error:
ORA-02000: missing ( keywordThanks

MichaelS for showing example to use function in table ddl , otherwise i was thinking we cannot use function in table ddl as per error I received.That was an example of a virtual column.
ORA-04044: procedure, function, package, or type is not allowed hereUsing PL/SQL code like that raises 2 basic problems. If that PL/SQL code for the calculating the column default breaks, what happens to the SQL insert statements against that table. These will need to fail as the table definition depends on the PL/SQL code. This is problematic as this dependency simply increases the complexity of the SQL object.
The 2nd issue is performance. PL/SQL code needs to be executed by the PL/SQL engine. This means a context switch from the SQL engine to the PL/SQL engine in order to determine the default value for that column. Context switching is a performance overhead.
So even if it was possible to use a PL/SQL function as parameter for the SQL default clause, I would not be that keen to use it.

Calling ORACLE Store Procedure with parameters in user define function

Hi everybody,
We have a scenario connecting Oracle DB thru JDBC adapter.
We have to call store procedure with input parameter and output parameter to retrieve data from DB. The implementation was made using JDBC adapter by building the correct XML message with EXECUTE action, and it works fine.
Now we need to use DB lookup within mapping. I wrote users define function with SELECT statement (using the JDBC adapter) and it works fine but I need to call store procedure in ORACLE instead of SELECT statement.
I found lot of examples concerning DB lookup but none of them explained how to write UDF calling store procedure in ORACLE with input and output parameters.
I am looking for an example.
Thanks in advance,
Gigi

I agree with you, but issue is we have lots of existing store procedure, which we need to call where damn required. I am sure those will be few but still i need to find out.
If you think you are going to get existing MS Stored Procedures or Oracle Packages that had nothing to do with the ORM previously to work that are not geared to do simple CRUD operations with the ORM and the database tables, you have a rude awakening
coming that's for sure. You had better look into using ADO.NET and Oracle Command objects and call those Oracle Packages by those means and use a datareader.
You could use the EF backdoor, call Oracle Command object and use the Packages, if that's even possible, just like you can use MS SQL Server Stored Procedures or in-line T-SQL via the EF backdoor.
That's about your best shot.

Calling PL/SQL user defined functions from ODI Constraints

Hi All,
We are trying to call user defined PL/SQL functions from ODI. We are able to call them from ODI's User functions. But when we are trying to call them from ODI Constraints under Models, it is throwing an error 'ORA-00920 invalid relational operator'. Kindly let me know if anyone has faced the same issue and got the resolution for the same. Thanks in Advance.
Regards,
Abhishek Sharma

Hi Ace,
Thanks for the response, the same error was coming in operator also.
I am able to call PL?SQL user defined functions from ODI Constraints. We have to first call ODI User functions from the ODI constraints as we cant call PL/SQL function (compiled in database) directly.
From the ODI User functions, we can then call the PL/SQL functions.
Please reach out to me if you need further details reg this.

How to migrate sql server 2000 user defined function returns table

Hi,
How do I capture the SQL Server 200 user defined function that returns table? Is this supported in the current version of Oracle Migration Workbench? I am using the latest version - Release 9.2.0.1.0 with SQL SERVER 2000 plug-in.
I was able to capture the SQL Server 2000 user defined function that returns string and smalldatetime but not the functions return table during the migrate data source stage.
Thanks in Advance,
Susan

Susan,
This is not currently supported. The next release of the Oracle Migration Workbench (due very soon), will do a better job of catching this mad reporting an error. We are looking into a suitable mapping and have created bug # 2355073 - TABLE DEFINITIONS NOT ACCEPTED FOR TABLE FUNCTIONS to track this issue.
Once possible solution we are looking into is using the object type to emulate. Here is an example from the bug:
Original table
SQL> create table tabela (a number, b number, c number, d number);
SQL> insert some values...
SQL> select * from tabela;
A B C D
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
SQL Server 2000 code
CREATE FUNCTION FUNCRETORNATABELA()
RETURNS TABLE
AS
RETURN SELECT A,B,C,D FROM TABELA
SELECT A,B,C,D
FROM FUNCRETORNATABELA()
ORDER BY A
Oracle code (workaround)
SQL> create or replace type MyObjType as object (
2 a number, b number, c number, d number);

SQL> create or replace type MyTabType as table of MyObjType;
2 /

Error in conditional map using User Defined Function

All,
In my mapping I basically have a user defined function that returns the filename of my inbound file from the adapter-specific message attributes (file adapter). I know this is coded properly because if I simply assign this function to my destination field I can see the filename in the payload XML.
However if I conditionally check that returned value using if,then,else I get an error message stating:
"During the application mapping com/sap/xi/tf/_MaterialData2ZcustProdMastMulti_ a com.sap.aii.utilxi.misc.api.BaseRuntimeException was thrown: RuntimeException in Message-Mapping transformation"
Essentially in my if I'm checking if the value returned by my user defined function is equal to the constant "SOMECONSTANT" then I'm setting my destination field to some other constant value. Otherwise it's equal to a different constant value.
Any thoughts?

Claus,
Thanks for the help. I actually had figured the problem out on my own. Sorry for not updating the thread sooner. What happened was this (as I suspected it wasn't related to my user defined function). For the newbies out there (of which I'm one) the problem was I was comparing strings in the graphical mapping tool using the Boolean "EQUALS" rather than the Text "EQUALSS".
Can you give yourself points for solving

How can I use Seeburger java functions on SAP XI's user defined functions?

Hi All,
As my title implies; how can I use Seeburger java functions on SAP XI's user defined functions? I've tried searching over the net in tutorials regarding this topic but I failed to find one; can someone provide me information regarding my question? thanks very much.
best regards,
Mike

Hi Mike !
You should check your documentation about which java classes you need to reference in the "import" section of your UDF. And also deploy the java classes into the java stack or include them as a imported archive in integration repository...it should be stated in the seeburger documentation.
What kind of functions are you trying to use?
Regards,
Matias.
