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)

How to call User Define Function

Hi,
I need a help....
In my Project I have Login.jspx page in which there is a textbox Username.
I have second success.jspx page which has its success.java bean class in which i have define a method "display()".Now i want to cal display() in my success.jspx page.
can anyone help me out what is the way to do this.
Thanks in advance...
Thanks,
Nehal

Hi Abhijit,
Sure i can give you more details on the same:
I have written a displayVal method in ForgotPassword.java bean class
public String displayVal() {
String txtVal = AdfFacesContext.getCurrentInstance().getPageFlowScope().get("testValue").toString();
nameID.setValue(txtVal);
return txtVal;
Now in ForgotPassword.jspx page i have one input text box named "nameID" in which i want to display some value from the user-define method called displayVal()
now i am trying to call my user-define method in my ForgotPassword.jspx page:
<af:inputText label="Name"
binding="#{backingBeanScope.backing_FrgtPwd.nameID}"
id="nameID"
value="#{backingBeanScope.backing_FrgtPwd.displayVal}">
</af:inputText>
but is is showing an error that: backingBeanScope.backing_FrgtPwd.displayVal is not a property as this a method.
So now my query is : Is there any way by which i can call my user-define method on the jspx page from the bean class of the same page.

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 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.

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.

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.

Bhavesh

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 copy head to line 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
