Defing user defined function in message mapping

hi experts of xi.
i want to create UDF for counting no of records in body and checking with trailer countinfo and adding all contract account amounts in file body and checking with trailer sum.
if these 2 comparings r not matched then we have to set flag field 'N' else we have to set as Y'.
waiting for ur answer.
regards.
seeta ram.

Hi,
pretty easy if you want to count number of lines (records)
two inputs (trailer and line segment)
and you can just compare it inside
then you can just return Y or N

User-defined function in message mappings

Hi experts,
I'm a senior c++ programmer, but I never write program by abap/java.
I want to create a user-defined function for mapping. Who can give me some instruction?
Many thanks.

SDN can. A simple search on SDN could provide you the steps and code as well. Try a search and come up with more specific doubts. I am sure most of the doubts would be gone.

How to migrate User Define Function to another mapping in other namespace

Hi Everybody
I have define many User Define Functions in mapping
How can i use them in other mapping
Thank you in advance

Hi,
I tried to explain the steps.
1. Take the JAVA code of your User-Defined Functions
2. Go to a JAVA editor (e.g NWDS, Eclipse, etc...)
2.1. create a Java project
2.2. create a Java class
2.3. inside your Java class, put each JAVA code of your User-Defined Function inside a Method
2.4. Export your Java class to a JAR file (e.g my_tools.jar)
3. Go to IR
3.1 create an Imported Archive (IA) and upload your JAR file.
3.2 in this IA, you see your Java class which contains all your methods.
4. inside your mapping,
4.1 create a User-Defined Function and import your class
4.2 use your method.
So, you define in only one place your code (thanks to a IA) and you will be able to use it inside several mappings.
I hope I don't forget steps...
Advantage: if tomorrow, you want to create a new function, just add a new method to your Java class and re-import your JAR file
Oh, I missed: your IA must be created inside a specific Software Component (SC__TOOLS) and this one must be linked with the others by a "Usage dependency", else your IA will be recognise only in one Software Component (and maybe only in one namespace)

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.

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.

Acces to XI R/3 table into user-defined function. Is possible?

Hi experts.
We want to do a user defined function in message mapping that reads a value in R/3 table. R/3 table is created in XI r/3.
It´s possible?. How i can do it?.
Thanks for all.

HI Julian
For your scenario, u need to create an rfc in the R/3 system and call that RFC from a user-defined function in XI by using the RFC Lookup facility..
Check out this following code...
com.sap.mw.jco.*;
public String Get_Customerl(String a,String b,Container container){
   //write your code here
JCO.Repository mRepository;
// Change the logon information to your own system/user
    JCO.Client mConnection = JCO.createClient(
            "300",         // SAP client
            "XYZ" ,       // userid
            "XYZ",       // password
            "EN",          // language
            "66.248.225.116",        // 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("ZGET_MATERIAL");
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters
input.setValue( a , "CUSTOMER" );
input.setValue( b , "NAME" );
mConnection.execute( function );
String ret = function.getExportParameterList().getString( "CUST");
mConnection.disconnect();
return ret;
This takes the customer number and name as input and the rfc maps these values in the table and returns the customer number if it exists in the database...
Hope u find it useful
Regards,
Hari

Abt user-define function

Hi all,
I need to add 3 nodes in an user-defined function in message mapping using java code.The nodes r like EmpFirstName,EmpMiddleName,EmpLastName.I am writing one user-defined function like "ADD".How can i call these field names into "ADD" Function.
Thanks,
Gopi.

Hi,
If you want to add the nodes to the input , then just add import parameters to the UDF.
If you want to create the multiple diff target nodes along with the values , then this would not be possible using an UDF.
it is possible to pass multiple values out of your UDF by writing an Advanced UDF , but, it would not be poissible to create multiple target nodes using an UDF.

Need user define function for the message mapping structure

Hi All
I am new to XI.I need the java code for Udf for the following structure.
i have two input and one out put as error.
order_nos----
user define function-------error message
order_details----
num of orders---- i.e. 10
order_details------ i.e. whole order records details
1.i have to compare the 1st input with 2nd one means if the ist input contain 10 means there are 10 orders in 2nd input.if not then i have to give error message .
2.then i have to check the fields in 2nd input has no null values.if no values the output will be error message.

User defined functions

hi,
i am using UDF(user defined functions) in my mapping.i defined the function in my mapping,but i want to use the same function in my other mappings.
here it is not visible in the new message mapping. i need o re-define same function for every nw mapping?
is there any other way ?

hi,
you can do this in SAP XI 7.1 latest version.there is facility to make the UDF as global function by putting it into global library.
then the same UDF can use in any Mapping that u define in future
but this facility is not there in lower versions of XI

User defined function in java for message mapping

I wrote the following user defined function in java for message mapping and mapped vendor with this. The aim of this function is to write a error file at defined path when i send empty Vendor value from File to RFC-Function module BAPI_PO_CREATE. The "err.txt" error file is not written when i execute in TEST but the value "ERROR" is returned to destination Vendor Field.
public String validation(String a, Container container) {
//write your code here
if (a.equals("")) {
try {
String source = "Vendor cannot be empty";
char buffer[] = new char[source.length()];
source.getChars(0, source.length(), buffer, 0);
for (int i = 0; i < buffer.length; i +=2)
f0.write(buffer);
f0.close();
FileWriter f1 = new FileWriter("/10.10.0.55/sapmnt/trans/edixiin/err.txt");
f1.write(buffer);
f1.close();
catch (IOException e) {}
return "ERROR";

Hi Senthil,
Check these things :
1) Whether you have permission to create a file in that directory.
2) try giving this
10.10.0.55
sapmnt
trans
edixiin
err.txt
3) Also check for permissions.
Hope this will help you.

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

User defined function during Mapping.

Hi,
I am trying to retrieve filename using user defined function.
The payload is simple.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:FTPTOFTP_MT_OB xmlns:ns0="urn://ftptoftp.com">
 <RECORD>
 <ROW>
 <EMPNO>723</EMPNO>
 <NAME>Jack</NAME>
 </ROW>
 </RECORD>
</ns0:FTPTOFTP_MT_OB>
the code for user defined function is
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;
now during message mapping ...
do I have to have extra xml tag in the destination
message which is now having
<?xml version="1.0" encoding="UTF-8"?>
<ns0:FTPTOFTP_MT_IB xmlns:ns0="urn://ftptoftp.com">
 <RECORD>
 <ROW>
 <EMPNO>723</EMPNO>
 <NAME>Jack</NAME>
 </ROW>
 </RECORD>
</ns0:FTPTOFTP_MT_IB>.
If yes ...
Then how to graphically map this extra xml tag.

Hi Deepak,
If u want to display the source file name in ur output, then ur output XML structure there should be an extra tag for displaying the file name.
In message mapping, select the user defined function which u have already created and map it to the tag for storing the file name in the target message XML format.
There is a editor present to write the user defined function on the bottom left corner of the message mapping screen.
For this function u need to select the Simple Function Tab.

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

Making a User Defined Function for Mapping in XI

Hi folks..
I knw how to make User defined Function in XI,
i was wondering about can we have any room for making a function for Initializing Purpose, which intializes few fields in source Message to some Global variables, and later we can use these Global Variables to set the the Target field
My Doubt is this...
i have Source & target Structure like this Structure like this....
SOURCE TEST DATA IS...
Parentsrc
 child1src a
 child2src b
 child3src c
 child4src hi
 child4src hello
 child4src hey
(On the basis of instances of child4src the istance of the Parentdst will be generated)
TARGET DATA SHUD BE LIKE THIS....
Parentdst
 child1dst a
 child2dst b
 child3dst c
 child4dst hi
Parentdst
 child1dst a
 child2dst b
 child3dst c
 child4dst hello
Parentdst
 child1dst a
 child2dst b
 child3dst c
 child4dst hey

Hi
You have to modify your target structure:
Source
Parentsrc
child1src a
child2src b
child3src c
child4src hi
child4src hello
child4src hey
Target
root
Parentdst
child1dst a
child2dst b
child3dst c
child4dst hi
Parentdst
child1dst a
child2dst b
child3dst c
child4dst hello
Parentdst
child1dst a
child2dst b
child3dst c
child4dst hey
</root>
Now map like this:
child4src -
Parentdst
child1src--|
child4src--| UseOneAsMany -- Splitbyvalue --- child1dst
child4src--|
child2src--|
child4src--|UseOneAsMany --Splitbyvalue --- child2dst
child4src--|
child3src--|
child4src--| UseOneAsMany -- Splitbyvalue --- child3dst
child4src--|
child4src -- SplitbyValue -- child4src.

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;
