Calling the function NUMBER_GET_NEXT from an XI User Defined Function

Hi there,
A number range object has been created on our XI server, called, ZBC_BKSTMT.
I need to call the function NUMBER_GET_NEXT (standard SAP function for number range objects) with the parameters:
NR_RANGE_NR = 01
OBJECT = ZBC_BKSTMT
Calling the NUMBER_GET_NEXT function will return a unique integer. However, i need to call it from a User Defined Function because I need to make use of the returned integer in my message mapping.
Thanks,

Hello,
If you have SP13, SAP provides a RFC API which can be called during the mapping. Refer to this document:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/xi-code-samples/xi%20mapping%20lookups%20rfc%20api.pdf

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?

Matias.

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.

Can we call proxy communication channel of type XI in user defined function

HI ,
can any body tell whether we call proxy communication (type xi) in an user defined function
regards
sandeep

Hi,
The Proxy is an abap coding only.
Hence it can be called from anywhere in R/3 region.
But we need to ensure that the SPROXY settings and proper linking between XI & R/3 are established.
I think, we can get more clarity on this from the Netweaver forum rather in R/3 ABAP.

How to Use Sequence Object Inside User-defined Function In SQL Server

I'm trying to call sequence object inside SQL Server user-defined function. I used
Next Value for dbo.mySequence to call the next value for my sequence created. But I'm getting an error like below.
"NEXT VALUE FOR function is not allowed in check constraints, default objects, computed columns, views, user-defined functions, user-defined aggregates, user-defined table types, sub-queries, common table expressions, or derived tables."
Is there any standard way to call sequence inside a function?
I would really appreciate your response.
Thanks!

The NEXT
VALUE FOR function cannot be used for User Defined function. It's one of the limitation.

What are you trying to do? Can you give us an example and required output?

How to use StreamTransformationException in user-defined function?

Hi,
I'm doing a DBLookup (using Java pgm in one of my Imported Java archives) for populating one of the fields in message mapping. If the DB connection fails, I want to terminate the mapping by throwing a StreamTransformationException from within a user-defined function.
I require urgent help in this regard.
Thanks in advance.
Regards,
Sridhar Rajan N

Hi,
I had the same problem. I failed to find the way how to throw a StreamTransformationException in my user-defined function. But I used another exception: NullPointerException. Yes, I know, this is not an elegant solution...

Message Mapping (user-defined function)

Hi all,
Is there anyway to determine the XML message ID using an user-defined function in Message Mapping? When I go to SXI_MONITOR I see that all messages have an unique ID, but I'm having some difficulties to understand if there is any way to get that ID in a message mapping and pass it to a target structure? I see that it is possible to use constants like "Sender" and "Receiver", but I haven't found anything for the message ID.
Can you please help me?
Thanks in advance.
Regards,
Ricardo Inácio

Try this code..
Create an UDF and do not pass any arguments to it..
java.util.Map map;
// get runtime constant map
map = container.getTransformationParameters();
// get value of header field by using variable key
String msgid = (String) map.get(StreamTransformationConstants.MESSAGE_ID);
return msgid;
Now map this udf to your target field. Now test it....
P.s. Since message id is run time property therefore in mapping test tab it will not work. Try it at runtime.

Sarvesh

How to check empty idoc fields in user defined function

Dear All,
I am working on an IDOC to file scenario. In my user defined function, I want to check whether a particular field of the idoc is populated. I can perform this test in message mapping by comparing the field with an empty constant.
How can I do the same test in an advanced user defined function? I have tried all the following, but none has worked so far
If (a.length == 0) .
If (a[0].length == 0)
If (a[0] == )
If (a[0] == )
Am I doing something wrong?
Thx/Farshad

To check whether an element is not available:
if (a.length == 0)
but you have to set cache to context. If you set cache to queue, it will not work, as in this case the context changes are part of the array a.
To check whether an element is empty:
if (a[0].equals(""))

Stefan

Determine Element maxLenght in User-Defined Function

Hi,
I have the problem, that I have to fill up several fields with leading 0. I wrote a User-Defined Function for this. But the function doesn't know how long this element is, so I have to give the function the length of the element.
Is it possible to determine the length of the current element in an extended User-Defined Function
Yours
Thomas

Hi,
>use a simple user defined function with the desired
>source element as input and give the following code...
>int k = a.length();
>String len = Integer.toString(k);
>return len;
That function will only give me the actual lenght of the input element, what I need is the max lenght of the target element...
>You can also use the built-in FormatNumber function to
>insert leading 0s.
How can I use this function to add leading zeros?
"'000'#" ? But there I have to do this for every element
>I think an easy solution for this is, just have a
>simple function with two arguments. The first is the
>element, the second is a constant, where you put the
>length.
Well I have this function. But I am looking for way to the safe the second argument ;o)
Thank you all for your help

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 distinguish the User-Defined-Function from Oracle Build-In function

Hi Friends,
I could get the function list form all_objects table by the SQL:
select * from all_objects where object_type = 'FUNCTION'
but there is no column in all_objects specify the function is build-in or user-defined.
But I found in SQL Server there is a column "is_ms_shipped" in the sys.all_objects table. This column will specify the object is build-in or user-defined. I want to get the equivalent column in Oracle but failed.
Could anyone tell me how to solve this problem?
Thanks,
Ricky

Thanks Pavan.
But if an user connects to database using "conn /as sysdba" syntax and creates a function. This user-defined funtion goes into the "SYS" schema also. I know it is not the best practise to create objects using sys user so I think your solution is right.

Ricky
