Message Mapping:: Java Function issue

we have PI7.1 SPS 07 & JDK version as JDK15.
I am using following program to calculate the Total of payments ( Put constants so it would be easy for others to test in their ESR )-->
BigDecimal sum = new BigDecimal("0.00");
BigDecimal bd = new BigDecimal("144.44");
BigDecimal hund = new BigDecimal("100");
for(int i=0;i<3028;i++)
sum = sum.add(bd);
//sum=sum.divide(hund);
String res=sum.toString();
result.addValue(res);
(Expression) 3028 * 144.44 = (CalculatorResult)437364.32 -
(PI Code result)437364.30
(Expression) 947 * 144.44 = (CalculatorResult)136784.69 -
(PI Code result) 136784.68
With numbers like 1347, 1047 etc I got difference of 1 Cent ( so like to call them as Magic numbers here). But numbers like 1119, 3026, 3027, 3028, 1100 etc give correct results.
One of my friend executed the same code in his Java environment & got correct results with magic numbers too with no 1 cent of difference.
Can you pls. test the same code in your environment & share the result and if it provides correct result then pls. share version of your JAVA environment too.
Thanks

I have to use the ADD function only, as I need to sum the payments made in whole context & queues.
I left the "hund" variable because I even tested following -->
Multiplied the number by 100 to remove the decimal places
Add them together "magic number" times
Multiplied result with 100
But still got the difference of 1 cent.
I will appreciate if you can execute the code given by me in you environment, you have to import java.math.BigDecimal

Concern on Message Mapping - Concat function

Hello Experts,
We have a concern in our message mapping structure. The target field is "Sold-To id" at line level and source filed is "Customer No" which appears in the header node. We are using a series of concat functions while mapping these two fields. Now, the issue is that the second concact function's input queue does not read all the values passed from the first concat function's output queue. We have checked their respective contexts but could not find the cause of this behaviour.
Due to this the mappiing fails and the target field is not populated with the required values.
Kindly advice.
Thanks in advance,
Elizabeth Jacob.

Hi Elizabeth,
You have
1 KUNNR value
2. VTWEG values
2 SPART values
And you wan two output to be generated (1 for each concatenated value of KUNNR, VTWEG and SPART). Is this right??
If yes then use the node function useoneasmany with KUNNR, so that KUNNR get repeated twice(one for each value of VTWEG and SPART)
Your mappign shoudl be like this
KUNNR --------------------------------|
VTWEG (context line)----------------| useoneasmany---------------------------------------| concat -----------------------------------| concat
VTWEG( do not change context) --| VTWEG( do not change context) --| SPART do not change context) --|

Message Mapping - java.util.Map

Hi There
I would like to know if there is any way, using java.util.Map map; to get the "data type" field name in a UDF? Passing a constant with the field name would not be practical.. I'm looking for a object oriented process to use in all my mappings.
Also where could I look for the methods I can use in the map trace object?
Regards,
Jan

But I'm still missing the field name..
Let say I have a message mapping going from Field ACB to Field QAZ and a UDF called CheckLen.
In my UDF I'm looking at the incoming field and if it's length is correct. if not I'm writing an entry into a table stating there was an incorrect field but what I can't get is the the field name so I can write to the table "Invalid length on field ACB" The only way to get this field name value is by passing a constant of "ACB" to the UDF and using that. But we have hundreds of MMs so implementing this would be much more difficult than a OOP way..

Message Mapping Split Function Problem

Hi All,
Could somebody plz help me on this problem of splitting the messege:
Source Field:
-MATMAS
-Idoc
     -EMARAM
       -MTART: 1,
                        2,
                        3
Target Required:
Based on the occurrence of Mtart, the target Idoc should be generated:
-MATMAS
-Idoc
     -EMARAM
       -MTART: 1
-MATMAS
-Idoc
     -EMARAM
       -MTART: 2
-MATMAS
-Idoc
     -EMARAM
       -MTART: 3.
Should I use a User-def function for the same or a split by value is sufficient.
I want to generate several idocs in my target if there are several Emaram segments in a single file in the source...!
Thanks & Regards,

Hi,
You cannot use Multi Mapping as you have the Idoc adapter on the inbound side. There is a work around though.
Use SAP note : 814393 and change the occurence of your IDOC from 1..1 to 0 to unbounded.
Your mapping requirement is notvery clear though. Can you give some more detail?

Message Mapping-Node Function

Dear All,
This is a problem in mapping, we are facing.
Source Structure
Item------Occurance= 1 to Unbounded (Level 1)
 Garment--- Occurance=1 to 1 (Level2)
Target Structure
target_Item--- Occurance = 3 to 5 (Level1)
 target_Garment--- Occurance=1 to 1 (Level2)
Source Data
<Item>
 <Garment> Blazer </Garment>
</Item>
<Item>
 <Garment> Blazer </Garment>
</Item>
<Item>
 <Garment> Blazer </Garment>
</Item>
<Item>
 <Garment> Shirt</Garment>
</Item>
<Item>
 <Garment> Trouser </Garment>
</Item>
Expected Target Data
<target_Item>
 <target_Garment> Blazer </ target_Garment>
</target_Item>
<target_Item>
 <target_Garment> Shirt </target_Garment>
</target_Item>
<target_Item>
 <target_Garment> Trouser</ target_Garment>
</target_Item>
Mapping Done:-
Item -
> target_Item
Garment -
>. Remove Context -
> Split By Value(Value Change) -
> Collapse Context -
> Split By Value(Value Change) -
> target _Garment
But we are getting the following error.
Cannot produce target element /ns0:sdntarget/target_Item[4]/target_Garment. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd
But when we see in DISPLAY QUEUE in the mapping Editor, every thing is showing as desired.
Can some body suggest, where we are wrong.
Regards,
Navneet

Hi,
As correctly said by Swarup change the occurrence.
What u did wrong is:
Item -
> target_Item -this mapping is not correct as from source u r getting four item hence the target_item will be generated 4 times.
Garment -
>. Remove Context -
> Split By Value(Value Change) -
> Collapse Context -
> Split By Value(Value Change) -
> target _Garment - this will generate only 3 times based on ur logic.
because of this u r getting error target_item[4].
use the below logic:
item-target_item
garment->splitbyvalue(value change)->collapse context-> target_item.
garment-target_garment
garment->splitbyvalue(value change)->collapse context->splitbyvalue(eachvalue)->target-garment.

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.

Writing message mapping function in Java in integration repository

Hi XI Pundits,
I am new to XI. I was working on Message mapping in intergration repository.
To map the source messages to target messages, we do graphical kind of mapping like drag and drop.
There are some functions aavilable at the bottom like concatehate, trim and etc. which we use if we need to modify the source message and map to target.
But in case we face a situation when we don't find the function which suits our requirement, I guess we need to write a new function. We can write these new function using Java only.
Can someone throw some light on this ?
What do we do to invoke java editor in integartion reposity to write mapping function in java ?
Can someone give an example of snippet of code ?
Thanks.

How to use standard java functions in a XSLT mapping

Hi All,
I wish to use a standard java function in a XSLT mapping, The issue is either i am giving incorrect namespace which is used to invoke the function or the signature of the function call is incorrect, I have read all the links in http://help.sap.com, and i know one can enhance a XSLT mapping by writing one's own java code and thereby using java standard functions , but the requirement is such that i need to try and use java standard function in XSLT mapping itself.
Please refer to the sample code below:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:javamap="java:java.lang.String">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:variable name="input" select="Title">
<xsl:if test="function-available('javamap:toUpperCase')">
<xsl:value-of select="javamap:toUpperCase($input)"/>
</xsl:if>
Author:<xsl:value-of select="Author"/>
</xsl:template>
</xsl:stylesheet>
error encountered is: Illegal number or type of arguments.
please reply if you have tried a similar scenario in SAP XI.
Thanks & Regards,
Varun

Hi Varun,
 First of all i want to tell you that as per the documentation you can only call the static function inside xslt mapping. Your toUpperCase method is a non static function.
What i am getting is that you have an element called Author and you want to convert its value into uppercase.
you can write your own user defined function which is static.
Signature of your java method :
public static string toUpperCase(String Author,Map inputparam)
try this xslt map.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:javamap="java:JavaProgram">
 <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
 <xsl:param name="Author">
 <xsl:value-of select="//Author_name"/>
 </xsl:param>
 <xsl:param name="inputparam" />
 <xsl:template match="/">
 <Author>
 <xsl:if test="function-available('javamap:toUpperCase')">
 <xsl:value-of select="javamap:toUpperCase($Author,$inputparam)"/>
 </xsl:if>
 </Author>
 </xsl:template>
</xsl:stylesheet>
Hope this will work.
Thanks and Regards

Message Mapping ... ABAP ,XSLT and JAVA

HI Friends
I have a general question ... but it will confuse me a lot ....
my question is we have four types of message mappings
1) GUI ( and UDFs)
2) ABAP
3)XSLT
4) JAVA
when we have plenty of options in GUI (and User defined functions also) to define sender 2 receiver message mapping
then what is need of JAVA,ABAP and XSLT Message Mapping and when we use these message mappings( exactly in which situation) and difference b/w them
Thanks in Advance
Mahesh

Green = recommended
Yellow = Acceptable
Red = not recommended
In my experience.
XSLT mapping: is confotable to convert to another format different to xml(when we do not have a complex logic)
Java Mapping: is to implement complex logics(but the maintainbilityis not good...you need a external tool)
ABAP mapping: I think is the best option when the you have the skills on that technology but take account that is not portable neither good for usability.
Regards
Ivan

How to use Advance java function in graphical mapping in XI 2.0?

Hi,
currently I am using a simple java function to make an RFC call to R3 system.
I want to avoid making connection for each lookup. Instead I want to make a single connection for whole message queue and get the corresponding values in some array or container object.
please suggest a solution.
I think this is possible using Advance java function, but I am not able to find any example on using Advance java function at help.sap.com.
thaks in advance.

Hi!!!
I'm not sure if I understood you well.
Do you want to preload some data into your structures in the memory and keep them there so you don't need to make a new connection during processing the whole message or every message?
In my opinion you can cache some data during processing a message, but it's impossible to cache some data between processing messages.
If you write your java mapping or you use graphical mapping (even with user-defined function), then you have a java class. The problem is that XI 2.0 reloads this class during processing every message, so even if you load some data from your data source into your structures in the memory, this data will be lost after reloading your mapping class.

Andrzej Filusz

Message Mapping: How mapping is handled in ABAP & JAVA STACK

Hi All,
I am interested in knowing how the mapping is hanlded in Background. Is that in ABAP or JAVA Stack.
Whats the architecture behind it?
Any documents related to it.
Thanks in Advance.
Best Regards,
Yaseen M

depends on the mapping technology:
i. Message, Java & XSLT (under Imported Archives) mappings are executed at Java stack;
ii. ABAP & XSLT (in ABAP stack) mappings are executed at ABAP stack.
The Integration Engine that processes the message pipeline (which runs in ABAP stack) will either execute a JCo call (using RFC Dest AI_RUNTIME_JCOSERVER) to the Java Stack to execute the mapping or, in the 2nd case, execute the mapping ABAP function directly.

Henrique.

Petre:
If you want to use standard functions then you try this:
If-->currentdate -OR- Constant(01.02)
currentdate -OR- Constant(02.02) --> OR -->
currentdate -OR- Constant(03.02)
Then give some output
Else give some output
So give the output for the first two conditions to another OR and the result of the third to the same OR. So whenever the condition is true in any of the condition you will get the THEN value else you will get the ELSE value.

Define Inbound Interface for Interface Mapping with Java functions

Hi,
we are developing an R/3-XI-ITK-SBO system. We realized our SOAP component as custom java functions and we installed it on ITK.
We need to import and configure these functionality in XI because we need to reference to it when we define the Message Interface and the Interface Mapping in Integration Builder Design.
Someone is able to tell us how we can import and configure these java function or definition in XI?
Thanks in advance.

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);
