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.

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.

  • User defined function for getting last string in the line

    Hi Experts,
    I am not java expert, can anyone give me user defined function for getting last string in the line.
    for example if the source field is "NEW ARBOUR SQUARE"  i want to pass to target field only last string that is "SQUARE"
    please help me out of this.
    Kind Regards.

    You don't even need a UDF for this. In the graphical editor look for the standard functions and once you do a scroll over on 'text functions; you will find what you are looking for.
    Just a piece of advice, try keeping UDF's to minimum unless really required or it is complicated without it.

  • Error in User defined function

    I have created a user defined function to make a call to SAP using JCo.
    But I am getting an error "package com.sap.mw.jco does not exist"
    Do we need to install JCo on our server?
    Thanks in advance

    Hallo Vijaya Kumari,
    if you use XI3.0 then you should check csn note 753294: 
    Symptom                                                                         
    A message mapping contains a user-defined function that uses a class            
    from the "com.sap.mw.jco", "sapxmltoolkit" or "com.sap.tc.Logging"              
    library. An error stating that the source code contains syntax errors           
    occurs when you test or activate the message mapping. When you use a            
    class from "com.sap.mw.jco", the system reports, for example, "package          
    com.sap.mw.jco does not exist".                                                 
    This error only occurs in systems containing a Support Package lower            
    than 5.                                                                               
    Solution                                                                        
    Import Support Package 5 or higher.                                             
    You can use the following workaround as a short-term solution: Upload           
    the library that is referenced in the message mapping into the software         
    component of the message mapping as an "imported archive". Do not               
    activate the "imported archive" with the library since it is not needed         
    for the runtime. The only purpose of the archive is to allow the message        
    mapping to be compiled. To avoid version conflicts with newer libraries,        
    you should delete the archive again after you import Support Package 5          
    or higher.
    In your case you will find the relevant jar file in the path
    [sap_j2ee_engine_installaltion_path]\cluster\server0\bin\ext\com.sap.mw.jco\jrfc.jar

  • Java user-defined function for mapping a complex structure

    All,
    Hope one of you can help me with this. I have a structure with over 15 fields and would like to concatenate all the fields into one target field and while I do this, I need to ensure that each field is padded with blanks as defined the data type. Can one of tell me if this is possible with a java user-defined function and if so, what type of logic is needed.
    Input_MT
    Field_1  string len=10 "need"
    Field_2  string len=6 "java"
    Field_3  string len=7 "help"
    Field_4  string len=8  "asap"
    etc,
    Output_MT 
    DataOut string  "need      java  help   asap    "
    (for some reason the exact spaces in between the words disappear in my Preview message)
    I have several fields in the input mt and therefore I find graphical mapping using concatenate and my own user defined function padWithSpace too messy.
    Thank you for you help.

    Hi,
    If your final req is to write all these fields next each other in a file, you can configure this in receiver file adapter by specifying the fixed length for each field.
    If you want the padded string as your MM o/p, you can create a simple user defined funtion with 15 fields as input and 15 constants for their lengths, and find out the length of the each string and pad it with required no of spaces.
    int max_len = 10;
    int actual_len;
    actual_len = a.lengh();
    for(int i=0; i < (max_len-actual_len; i++)
    a = a.append(" ");
    return a;

  • 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.

  • Getting "Unexpected end of formula" error in user-defined function

    I created a user-defined function and registered it successfully in Discoverer Admin (10g), and it shows up in Discoverer Plus. However, when I call the function, I get this error:
    "Error in formula -- unexpected end of formula"
    If I hard-code in parameters, I can successfully run the function as such from Oracle SQL Developer:
    SELECT PAYLINETOT('2324', '111', to_date('01-Sep-2010'), to_date('31-Oct-2010'))
    FROM DUAL;
    But I still get the same error if I enter this in the calculation dialog in Discoverer:
    PAYLINETOT('2324', '111', to_date('01-Sep-2010'), to_date('31-Oct-2010'))
    Any idea what's going on and how to get this to work?

    Michael,
    I tried your suggestion, and this time I got a different error message that said that the function had not been registered with the EUL. I thought I had registered it, but when I checked, the return data type was wrong. I corrected it, and the function is "valid" in Discoverer Admin. Yet, when I go back to Discoverer Plus and attempt to use the function (and yes, I logged out and logged back in), I get the same error message:
    "Error in formula - unexpected end of formula - Error: Function PAYLINETOT has not been registered with the EUL."
    Any idea where the disconnect is? Are these two separate errors? How could Discoverer Admin tell me that the function is registered and Discoverer Plus tell me otherwise? And yes, I've made sure that the "Available in Desktop/Plus" checkbox is checked.

  • User - defined functions for calculating the taxes of state and country

    hi expects,
        how can write user-defined function in message mapping in which i want to calculate the states taxes (2500) and country taxes (5000) and give the result as grand total in output.please help me?

    Hi,
    Activities
    1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
    graphic is explained in the accompanying text), which is located on the lower left-hand side of the
    screen. In the menu, choose Simple Function or Advanced Function.
    2. In the window that appears, specify the attributes of the new function:
    Name
    Technical name of the function. The name is displayed in the function chooser and on the data-flow
    object.
    Description
    Description of how the function is used.
    Cache
    Function type (see above)
    Argument Count
    In this table, you specify the number of input values the function can process, and name them. All
    functions are of type String.
    3. In the window that appears, you can create Java source code:
    a. You can import Java packages to your methods from the Imports input field, by specifying them
    separated by a comma or semi-colon:
    You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
    all message mappings require these packages and therefore import them. You should be able to
    access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
    package under Import. In other words, you do not have to import it as an archive into the Integration
    Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
    SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
    In addition to the standard packages, you can also specify Java packages that you have imported as
    archives and that are located in the same, or in an underlying software component version as the
    message mapping.
    b. Create your Java source text in the editor window or copy source text from another editor.
    4. Confirm with Save and Close.
    5. User-defined functions are limited to the message mapping in which you created the function. To
    save the new function, save the message mapping.
    6. To test the function, use the test environment.
    The new function is now visible in the User-Defined function category. When you select this category,
    a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
    function to the data-flow editor, choose the arrow next to the button and select from the list box
    displayed.

    My requirement is to remove these kind of wrong lines(entire lines to be removed) whenever XI reads the data. For this what is the standard function i can use in mapping. I thought I can create my own function to remove such kind of false data lines. It would be helpful for me if some body provide me the java code.
    Thanks very much.

  • User define function for SQL Server

    Hi all,
    it's possible to write an UDF for SQL Server in Java?
    I know that it is possible with DB2 and Oracle.
    My main goal is to write an UDF that works well with all of these DB.
    Thank's

    Hi all,
    it's possible to write an UDF for SQL Server in
    Java?Okay, JDBC can talk to any database (given you have a driver implementation). Also, JDBC is like a conduit. So the real question is likely, will your database let you do this?
    I know that it is possible with DB2 and Oracle.
    My main goal is to write an UDF that works well with
    all of these DB.I also don't know what a UDF is, but if you ARE talking about stored procedures, then no, it's not possible. All databases are different. On that note, I typically recommend NEVER using stored procedures unless absolutely necessary.
    But it also sounds like you want to do this at runtime. I've seen systems that do this (bind stored procs at runtime dynamically) and it's a freakin nightmare! So be careful.
