Question in User Defined Functions....

Hi,
Can I develop new User Defined functions in ABAP programming language rather than in Java? If Yes, how and if not why?
Sorry, if this is a petty question as I am in the process of learning XI.
Thanks,
Monica

Hi,
yes it's a stantard function module
which you can call from abap mapping
there's no possibility to create user defined function
that you could use in graphical mapping in abap
take a look at this document on how to do abap mapping:

Questions about user-defined functions

Hello all,
I've got some questions about user-defined function in a message mapping:
1) How can I get the current date/time in format yyyy-mm-dd hh:mm:ss ? What is the java code for this?
2) I want to use the StreamTransformation constant TIME_SENT, only this is not in the right time-zone.
It is GMT and it should be CET (1 hour difference). How can I convert this in Java?
Can somebody help me with this?
Thanks in advance.
Kind regards,
Marco van Iersel

Hi Marco,
If the date format is fixed as you have mentioned,please use this:
                                String test = "2009-03-27 23:15:30";
          String test1 = test.substring(11,13);
          if(!test1.equals("23"))
          int a = Integer.parseInt(test1);
          int b = a+1;
          System.out.println("b"+b);
          String c = Integer.toString(b);
                                test = test.substring(0,10)+" " + c + test.substring(13,19);
                                return test;
          if(test1.equals("23"))
          test = test.substring(0,10)+ " 00" + test.substring(13,19);
          return test;
                                else return "";
Kindly let me know if this works.
Thanks.

Multi mapping question using user defined function

Hi,
I have a message with multiple occuring nodes (i.e. one message with multiple orders (header + detail)) that I need to map to a idoc. I need to filter out of the source based on order type (in header) from creating an idoc.. How do I do it using user defined function + message mappping ?
mad

All - Thanks much.. Here is my requirement that is no solved by regular mapping
<Root>
<Recordset>
<Ordheader>
    <ord>
    <ord_type>
</Ordheader>
   <Ord_line>
     <ord>
     <Linnum>
   </Ord_line>
</Recordset>
<Recordset>
<Ordheader>
    <ord>
    <ord_type>
</Ordheader>
   <Ord_line>
     <ord>
     <Linnum>
   </Ord_line>
</Recordset>
<Root>
As you see above, each recordset has order transaction. One Root message can contain multiple of these. So, when I map to the IDOC, I want to filter out any ord_type <> XX.
If I use regular graphical map, it only looks at first recordset and accepts all or rejects all.
I need to use UDF. In the UDF, what comes in as input ? Resultset is output -correct ? Now how do I usse graphical mapping with UDF to generate the correct target info

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.

User Defined Function (Part 2)

Hi,
István Korös has finally solved my problem on User Defined Function.
See
My objective was to write a simple UDF to represent the following formula which Gordon Du gave me:
(DATEADD (s, -1,
DATEADD (mm, (DATEDIFF (m,0,@refdtzz ) + @mthnumber), 0)))
However, the solution proposed by István, although it works perfectly, leaves me scratching my head. Let's see why?
The only difference between my solution and that proposed by István is that István enclosed the UDF name between .
I wonder how this can make the vital difference between a (simple query!) that works well and one that gets blocked.
I tried several combinations of and am in for a few surprises, listed below. Can anybody explain what's going on?
Solution proposed by István:
CREATE FUNCTION [dbo].[udf_EndOfMonth]
and executed as:
select [dbo].udf_EndOfMonth (@refdt1 , 1)
Remarks: works perfectly
If I execute the UDF with exaclly the same name as in CREATE, it does not work
CREATE FUNCTION [dbo].[udf_EndOfMonth]
and executed as:
select [dbo].[udf_EndOfMonth] (@refdt1 , 1)
Error Msg: Must specify table to select from
If I don't put the , the function is created, but the execution of the calling query returns error
CREATE FUNCTION dbo.udf_EndOfMonth
Remarks : Creation OK
and executed as:
select dbo.udf_EndOfMonth (@refdt1 , 1)
Error Msg: Must specify table to select from
It seems that the only combination that works is that provided by István.
This is surely a simple UDF.
I don't know what to do if I attack a more complicated UDF.
Grateful if anybody could help light my way.
Thanks
Leon Lai

Hi Leon,
As István has already pointed out, there is no documentation for those small differences to make the SQL work or not. He must be tested quite a few times to find the actual working code. This question can only be answered by the developer who made this part for B1.
Thanks,
Gordon

Error in User defined function for dynamic file naming

Hi,
While creating User Defined function with this following code for dynamic fieldname
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
which options should i select for cache Value, Context, Queue
for Augument , what name shd i mention.
Regards,
Varun

Hi Varun,
I guess I have answered a similar question just a few minutes before on very similar post from you. Just pasting the same here .................
Are you trying to access the ASMA values from the SOAP header of the XI message for the source file name?
First of all you need to Set the Sender File Adapter for Set ASMA and then file name. So it will work fine when you actually run the scenario end to end.
But in the mapping tool when you test the mapping - there is not message header updated with the actual source filename - and whenever you try to read the FileName attribute in the message header from the UDF - it cannot find the object and returns a NullPointerException.
I would suuggest for your mapping tool testing to be successful, have a check in the java code for null values,
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
If (ourSourceFileName != null)
Return ourSourceFileName;
Return "NoFileName.txt";
Let us know if this works.

Suddha

Java class within user defined function

Hi all,
in order to have a JDBC-lookup java function "globally" in XI i created a java class and imported it to XI as an imported Archive (i have to do the lookup within a mapping). I then can include the class to a user defined function. However the problem is now that this works fine within one Software Component Version but when i want to use it in several SWCV i have to import the jar to every SWCV. My question is therefore if anybody has already had this problem and if there is another possible solution - maybe deploying the class to XI using SDM?
Thank you for your thoughts.
Mathias

hi Markus,
>>>>My question is therefore if anybody has already had this problem and if there is another possible solution - maybe deploying the class to XI using SDM?
if you do that then you'll have to remember about it
every time you import a new SP or upgreade your XI
this is not standard so SAP may always overwrite it
and your interfaces will stop working
consider importing it for every SWCV

10g - cache, report contains oracle user defined function

hi, experts,
from http://obiee101.blogspot.com/2008/07/obiee-cache-management.html
Reasons Why a Query is Not Added to the Cache:
•Non-cacheable SQL element. If a SQL request contains Current_Timestamp, Current_Time, Rand, Populate, or a parameter marker then it is not added to the cache.
•Non-cacheable table. Physical tables in the Oracle BI Server repository can be marked 'noncacheable'. If a query references any non-cacheable table then the query results will not be added to the cache.
•Cache hit. In general, if the query gets a cache hit on a previously cached query, then the results of the current query are not added to the cache. The exception is query hits that are aggregate roll-up hits.
•Result set is too big.
Query is cancelled. This can happen by explicit cancellation from Oracle BI Presentation Services or the Administration Tool, or implicitly through timeout.
•Oracle BI Server is clustered. Queries that fall into the ‘cache seeding’ family are propagated throughout the cluster. Other queries continue to be stored locally. Therefore, even though a query may be put into the cache on Oracle BI Server node 1, it may not be on Oracle BI Server node 2.
I would like to know
if the request (report on dashboard) calls an oracle user defined function, can the cache be created and saved for this report?
thank you very much!

Hi stephen,
if the request (report on dashboard) calls an oracle user defined function, can the cache be created and saved for this report?Yes,it is cached.....function defined in database is called in OBIEE is cached and saved.
More information and example can be found here http://oraclebizint.wordpress.com/2007/09/10/oracle-bi-ee-10133-support-for-native-database-functions-and-aggregates/
Hope it helps you.Check all other questions you posted are answered?

SQL User Defined Functions for performing statistical calculations

Hi!
   I hope you can help. I just wasn’t sure where to go with this question, so I’m hoping you can at least point me in the right direction.
   I’m writing a SQL Server stored procedure that returns information for a facility-wide scorecard-type report. The row and columns are going to be displayed in a SQL Server Reporting Services report.
   Each row of information contains “Current Month” and “Previous Month” numbers and a variance column. Some rows may compare percentages, others whole numbers, others ratios, depending on the metric they’re measuring. For each row/metric the company has specified whether they want to see a t-test or a chi-squared statistical test to determine whether or not there was a statistically significant difference between the current month and the previous month.
   My question is this: Do you know where I can find a set of already-written user defined functions to perform statistical calculations beyond the basic ones provided in SQL Server 2005? I’m not using Analysis Services, so what I’m looking for are real SQL User Defined Functions where I can just pass my data to the function and have it return the result within a stored procedure.
   I’m aware that there may be some third-party statistical packages out there we could purchase, but that’s not what I’m looking for. And I’m not able to do anything like call Excel’s analysis pack functions from within my stored procedure. I’ve asked. They won’t let me do that.   I just need to perform the calculation within the stored procedure and return the result.
   Any suggestions? Is there a site where people are posting their SQL Server UDF’s to perform statistical functions? Or are you perhaps aware of something like a free add-in for SQL that will add statistical functions to those available in SQL? I just don’t want to have to write my own t-test function or my own chi-squared function if someone has already done it.
Thanks for your help in advance! Oh, and please let me know if this should have been posted in the TSQL forum instead.  I wasn't entirely sure.

HRMS user defined functions

Hello, I have a function I've defined (From the Define Function window). It uses context and normal parameter values. My question is, after defining a function, should I always bounce the server because from what I'm seeing, I'm getting an error each time I try to use the function in my formula. I've setup my function as a "User Defined Function" not "External" function.
Also, how do I know if a function can accept context parameters. I want to use the ASSIGNMENT_ID context for a formula I'm defining for Appraisal Competency Line Scoring to calculate a competency score and I was wondering if ASSIGNMENT_ID was ok as a context.
Thanks.

If you create a function and call it from a fast formula, make sure the parameters you pass from the FF to the function are in the same sequence.
Make sure that the return value TYPE from the function corresponds to the return variable in the FF.
Also, compile the FF again, after you have created the function.
Regards
Tim

User define Function at Mapping Time

Hello Everyone,
My requirement is I input the one value to the user define function (at mapping time). That function calls the RFC to R/3 system and return the 3 output values. Now my question is how can I return 3-output value from the user define function.
What is the other possibility to solve this type of problem?
Where we have one input parameter and more than one output parameter.
If any one did this kind of job. Please give me the idea how can I solve this.
Regards,
Gaurav Jain

Hello Richard,
Are you talking about <b>copy head to line</b> example given in MappingFunctionality.pdf.
In my scenario:
Input - NULL
Output - OP1, OP2, RESULT
And I write my Advance user define function as
import com.sap.mw.jco.*;
public void Lookupfunction(ResultList result, Container container){
JCO.Repository mRepository;
// Change the logon information to your own system/user
JCO.Client mConnection = JCO.createClient(
    "100", // SAP client
    "user", // userid
    "pass", // password
    "EN", // language
    "hostid", // host name
    "00" ); // system number
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "SAPLookup", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("ZTEST2");
function = ft.getFunction();
mConnection.execute( function );
result.addValue( function.getExportParameterList().getString( "OP1" ) );
result.addValue(function.getExportParameterList().getString( "OP2" ) );
result.addValue(function.getExportParameterList().getString( "RESULT" ) );
mConnection.disconnect();
But it shows me only one field as output in mapping icon.
so as per the mapping document i attach splitbyvalue over that but in the example only one field at the output side where i have three field.
How can i solve the problem?
Even i check in XI 2.0 System it doesn't show output at all.
Thanks & Regards,
Gaurav Jain

Access to whole payload in user defined function

Hi,
is there a way to access the whole XML payload in a user defined function or is it necessary to employ a Java mapping?

Accessing a Cache From an Oracle CQL User-Defined Function

According to the docs ...
I am to use the following element to set the cache property in my bean...
<wlevs:property name="cache" ref="cache-id"/>
However, when I set it, the assembly does not validate.
If I use <property>, I get a NullPointerException on each request when my processor runs.
Using the same CQL code..
Without the <property> tag, the call to the user-defined function works (but I don't have the cache attribute set obviously).
Here is the excerpt from my assembly...
<bean id="cacheFunction" class="ou.cep.function.CacheFunction">
<property name="cache" ref="myCache"/>
</bean>

<wlevs:processor id="myProcessor">
<wlevs:listener ref="CacheChannel"/>
<wlevs:function ref="cacheFunction" function-name="isValidID" exec-method="isValidID">
</wlevs:function>
</wlevs:processor>
To repeat, with the same CQL with the user-defined function call, if I remove the property element from the bean definition, I can call the function successfully (it just doesn't do what I need it to do). In this case, I am still using the ref=cacheFunction for the wlevs:function within the processor.
What am I doing wrong?
Edited by: fl0at on Oct 5, 2010 12:22 PM
Edited by: fl0at on Oct 5, 2010 12:28 PM

The case is solved, not sure I could explain why, but...
This implementation of the user-defined function was a migration from an implementation using the same cache in the join. So, when I removed the cache reference in the source stream (where I am now executing a function that accesses the cache), the problem went away and everything is working.
I can explain further if there are questions.
If anyone has thoughts on this, please advise.
As always, thanks for the help.

Regarding sqlserver user defined functions

Hi,
How to write user defined functions dynamically?
Please help me in any situation

Hi Bellam,
You post same question 2 times. Please avoid this practice on Forum, I
have merged the same thread into this thread.
As other post, dynamic SQL is not allowed in user defined functions (UDF), however, you can execute dynamic SQL store procedure with parameter. A user-defined function takes zero or more input parameters and returns either a scalar value or a table. There
is different between user-defined stored procedures and
user-defined function. User-defined functions do not support output parameters.
For more information, you can review the article about User-Defined Functions(UDF).

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

Question in User Defined Functions....
