Message mapping/UDF help..

Hi experts,
Can someone let me know whether there is a chance to fulfill the below requirement:
Input file:
In the Input CSV file, there is a fixed length field with length 9 char and has leading zeroes (ex: 000000650)
Output file:
In the O/p XML file, the corresponding value should be displayed as "6.50" (Have to remove the leading zeroes, right justified and the last two digits should be allocated for decimals)
Can anyone let me know if we can handle in Message mapping or should we write a UDF? If so can you please provide the code..
Any help would be highly appreciated !!
Thnx
- Ravi

Hi Ravi,
UDF:
Create a function zerosuppress and take the cache as value and take one argument input. Then put the code below:
//Put this code
String output = input.replaceFirst("^0+","");
return output;
With this function your leading zeros will remove.
Then map like this:
source field --> zerosuppress (udf) --> divide by 100 --> target field.
This should solve your issue.

Export parameter in Message mapping UDF

Hi, I use PI7.1.
I defined an Export parameter in Message mapping "Signature" tab.
And as http://help.sap.com/saphelp_nwpi71/helpdata/en/43/c3e1fa6c31599ee10000000a1553f6/frameset.htm,
I wrote in my UDF as follows:
public String myudf(int var1) {
String str="test";
if(exists("MY_PARA") == true) {
getOutputParameters.setString("MY_PARA", str);
return str;
However when I ran the test, it said there is "syntax error".
I guess the reason is not found the method exitst() or getOutputParameters. Anybody can help? thanks

Message mapping logic help

Hi All
I have a source structure like this below. It's a big structure actually. I'm just pasting the relevant structure where I need your help.
</root>
     <storage>
         <id>AB</id>
         <Type>TY</storType>
         <Temp>100</Temp>
    </storage>
----</root>
My requirement is to check the value coming in <Type> and if it is TY, then the target structure will be the exactly the same
If it is XY, then the target structure will have one more field <celsius> and will look like this below.
</root>
     <storage>
         <id>AB</id>
         <Type>TY</storType>
         <Temp>100</Temp>
         <celsius>922</celsius>
    </storage>
----</root>
The <storage> complex element with elements can repeat as many times in the source XML. But the values of <Type> will be either TY or XY and I have to create the target structure accordingly. Pls help. I am using graphical message mapping

Message mapping : UDF parameter string type versus default UTF-8 encoding

Hi,
I'm facing an issue with character encoding when using an UDF to transform into base64 encoding.
While thinking about the subject, I'm not 100% sure if it's possible to get it to work corerctly :
Given :
-The input XML is encoded UTF-8 ( with a special characeter )
-The UDF is generated with java parameter type 'string' ( = set of 16bit unicode characters )
Doubts :
-What is supposed to happen when a node content ( of message encoded in UTF-8 ) is used as input for the UDF string type parameter ? Is the node content decoded/encoded correctly by PI automatically ( at input/output versus the internal 16bit unicode character string ) ?
( I would assume yes )
-Is the default charset of the underlying JVM relevant ? Or does pi always use explicit charsets when encoding/decoding ?
( I would assume it's not relevant )
The UDF java code considers the string as a array of chars while processing them. It uses methods .length and .charat on the input string.
The result is that I have a ISO-8859 encoded string ! ( after decoding it back from the base64 )
What could cause this ?
regards
Dirk
PS If I simply use default functions ( concat etc..) then the resulting xml stays correctly encoded...

Hi,
But that would mean that an UTF-8 encoded byte array would be passed unconverted to the UTF-16 unicode string parameter ?
Shouldn't that trigger an exception ?
I'm going to make some tests and see if it enlights my knowledge ( empirical )
Keep you updated,
thanks
dirk

Message Mapping UDF

Hi Guys,
For the UDF functions for messagemapping,Its a pain to code it using the dataflow editor provided in the repository.
We are having the XI version 3.0(SP 20).
So I decided to use eclipse for coding and debugging the functions and then copy it to the UDF editor for usage.
Have downloaded the Eclipse-SDK 3.0.02 Version and is going to use the the JDK version(1.4.12)
Is that Okay?(I mean is it compatible with the XI version).
I have the aii_map_api.jar already with me.
What is the above ".jar" for and what do they contain?
Have read somewhere that I need the aii_mt_rt.jar and aii_utilxi_misc.jar as well.
What are they for and what do they contain?
If I need the above said jars,Is there any java plug-in available.
Thanks
P

Hi P,
For writing UDF's you dont need all these jar file!!!! they are required either for java mapping or module creation..
BTW you can use any java ide to write this simple piece of java codes (even notepad will do )

Export Parameters in Parameterized Message Mapping does not work.

Hello, XI-Gurus!
I have a question: how to use an EXPORT parameter in Parameterized Message Mapping? seems it does not work...
(I use XI / PI 7.1)
For example, I have a follow scenario: a large message comes to XI from one BS (message contains a lot of rows), then this large message splits to some small messages (something about 1000 rows in one small message), and send small messaeg one by one from XI to second BS. So, after receive step I use a transformation step with Parameterized Message Mapping to get a total amount of rows in large message (it needs for making condition for loop in IP, for example). I want to use an EXPORT parameter to pass this number from Parameterized Message Mapping to Integration Process. How can I do it?
Of course, I know the way to how to make this scenario without any parameterizing, but I want to use exactly "Parameterized Message Mapping" like it writes in this help:
http://help.sap.com/saphelp_nwpi71/helpdata/en/43/c3e1fa6c31599ee10000000a1553f6/frameset.htm
This topic contains something about procedure how to use an EXPORT parameter, but this procedure does not work. I don't understand how to write this UserDefined Function, which I can set any export parameters.
I read this blog:
/people/jin.shin/blog/2008/02/14/sap-pi-71-mapping-enhancements-series-parameterized-message-mappings
this blog has NO solutions about EXPORT parameters. about IMPORT parameters - everything OK.

Hi Rudolf,
It still does not works.
Great thanks for all your answers! If your advice works on your PI-server, it means that my problem not in UDF.
Step by step:
1) I create in "Signature" tab two parameters: FILE_NAME, FILE_TYPE (of course, they both Export and xsd:string type)
2) Then, I goes to "Functions" tab and create new function "testUDF" with one argument var1.
3) In body of this UDF insert 2 strings:
getOutputParameters.setString("FILE_NAME" , "Order");
getOutputParameters.setString("FILE_TYPE" , "PDF");
4) in "Definition" tab I bind function "Local.testUDF" with one field in my input message and goes to "Test" tab for testing.
5) And then I have a message window "Problems While Testing":

Fauver,
Just to narrow down the problem first remove the first udf and only use the 2nd user defined function. Also in the 2nd udf you have to change this line:
try{
// 1. Determine a channel.
Channel channel = LookupService.getChannel(Sender, "R_RFC_ERP");
In the above line instead of Sender you use the business service or business system where R_RFC_ERP RFC communication channel is created in Integration Directory. So you are hardcoding it first.
Once you have done this changes do save and test it once again. If this works then you can change back to original and your first udf needs to be checked.

How to Alert RFC connection failure via message mapping? Kindly Help!

Hi Experts,
    I have a JMS - XI - RFC scenario.
JMS receives the Rosattenet PIP contents and sends it to RFC function module in remote SAP R/3 system.
   I have a requirement where I have to monitor RFC connection failure because of the remote R/3 system being down. I have to send a email alert where the subject contains the PIP number to understand for which PIP the connection failed.
The PIP number exists in the PIP content at the interface.
If I use the Alert configuration in the runtime workbench for monitoring then I cannot dynamically pass the PIP number.
Only way I think of triggering alert is in the message mapping via a Java UDF.
But I am not sure how can I do this? How do I check in the UDF if RFC connection has failed? Is this the correct approach?
How to acheive my requirement? Note that my email subject content is dynamic bacause if PIP number.
Please help!
Thanks
Gopal

Hi Gopal,
what version/sps of XI are u running?
The easiest way to do what u want inside a UDF is to
1. use JCo to try estabilish a connection to the remote SAP System
2. if that fails, use JavaMail to send an email message
Let your UDF work on the PIP number, accepting it as input, and (maybe) returning it as output if everything goes ok. Otherwise break the mapping execution as described by Michal in one of his last weblog (using Dynamic Configuration).
Note that the above method doesn't guarantee that the message will be actually delivered, as some seconds could last between your check and the real RFC delivery operated by the Adapter Engine...
I am evaluating a way to do the same with Alert Framework. I will let you know the result!
Cheers,
Alex

GlobalContainer object values acessed among UDF's in message mapping ?

hi
i have scenario where i am using globalContainer variable functionality in my message mapping.
in edit java section
String usr;
Container container ;
GlobalContainer globalContainer ;
intialize usr = "";
in First UDF
String inlogin_sess = " ashutosh test value" ;
globalContainer.setParameter(usr,inlogin_sess);
return any value :
now if i create another 2nd UDF and use :
String out =globalContainer.getParameter(usr);
return out ;
now 2nd UDF is giving null pointer exception...
for testing the code functionality..
IF i use the SET and GET in 1st UDF :
globalContainer.getParameter(usr);   in 1st UDF than it is working sucessfully...
globalContainer.setParameter(usr,inlogin_sess);
String out = globalContainer.getParameter(usr);
return out ;
in help.sap it is mentioned that Globalcontainer objects values can be fetched   among UDF's in one message mapping....
[http://help.sap.com/saphelp_nw04/helpdata/en/0f/80243b4a66ae0ce10000000a11402f/frameset.htm]
i have gone a lot of thread in sdn where Global container are used like sequence no creation etc, but every where the
GET and SET are used in SAME UDF...
any clue where is leak..
Regards,
ashutosh R

Hi Abhishek
Your point is legimate, but for my their is no such issue..
even i try to use it as :see image..
[http://www.screenshots.cc/show.php/14137_GlobalVariable.JPG.html]
UDF1 :
globalContainer.setParameter(usr,inlogin_sess);
return any value :
and in UDF2
String out = globalContainer.getParameter(usr);
return out ;
mainting the sequence
My concern is object globalContainer is local in UDF1, so it will through nullpointer ,if we try to access in UDF2.
if we declare globalContainer   in edit jave -GlobalVariables also, still it is having the error..

UDF works in Message Mapping but not in Interface Mapping

Hello,
I have encountered a very strange problem. I use a simple UDF in a message mappings which imports a class that has been imported as "imported archive".
This works perfectly fine when testing the message mapping itself.
However when I execute the message mapping within a interface mapping I get a Java Error indicating that resources are missing (com.sap.aii.ib.core.mapping.ResourceNotFoundException) This error refers to a missing class.
How can this be? Message mapping works but not when using it in a interface mapping.
Do you have any idea?

Hello,
this is what I have already tried, with the same result. But now I have come to a conclusion. It is a little bit tricky, but maybe also helpful for others:
A method of a class (part of the imported archived) itself calls a class which throws an exception. This exception however is handled by the method itself and does not affect the overall outcome.
In the message mapping itself you do not see the error message, only in the interface mapping. Result however is the same.
Maybe the trace level is set different for mesage and interface mapping.....

Edited by: NagaDurga Nannapaneni on Oct 16, 2008 1:07 PM

Hi ,
Think the error is coming because the content in imported archive is not being taken into message mapping at all...so package, class, method ..nothing is identified.
Can anyone suggest the solution..
Thanks,

UDF in message mapping instead of Java Mapping. Pls advice urgent

Hi All,
My scenario
CRM --- XI -- CRM
In XI I have to open socket connection.
Pls refer link:
/people/saravanakumar.kuppusamy2/blog/2005/12/15/socket-integration-with-xi
Can Java Mapping code given in above link for socket connection can be used in Message Mapping (CRM -- CRM)UDF?
Pls advice urgent
Regards

Hi Henry,
I understood your requirement.
But as per the architecture of XI/PI some message has to trigger your scenario.
In this case there is no adapter where you can directly communicate with CRM system.
Do one thing configure a dummy scenario on the sender side.
Use File adapter for simplicity. once it pools the file with some dummy data in the file it comes to Interface mapping(message mapping) of the PIPELINE steps. Now use the code as you mentioned above(within UDF) for opening socket to CRM system and implement you business logic within that program and write the response to target interface which will infact talk with CRM system.
Dont forget to do the coding in an infinite loop with some delay (if required). Other wise every time you have to put a message for File Adapter for triggering purposes.
You can also acheive the same if you use Java Mapping instead of Graphical mapping with UDF(code for Opening socket and business logic). I suggest you to use Java Mapping.
I dont know how you will comunicate with CRM system on receiver side.?
Thanks,
Gujjeti
