XI message mapping clarifications

Dear All
I would like to know if XI message mapping(graphical mapping) can be
used for mapping based on the order of elements given in the XML source
message.
For example I have a source message as below
Source XML:
<Source>
<givenname>Ramesh</givenname>
<givenname>Kumar</givenname>
<givenname>Ganapathy</givenname>
</Source>
semantic is first instance of <givenname> needs to be mapped <firstname> in target,
Second occurance of <givenname> needs to be mapped <secondname>,
Third occurance of <givenname> needs to be mapped <familyname>
Target XML
<Target>
<firstname>Ramesh</firstname>
<secondname>Kumar</secondname>
<familyname>Ganapathy</familyname>
</Target>
As I understand graphical mapping editor works based on Xpath
expressions, Is it possible to achieve such mapping schematics with
graphical mapping and UDF in XI.
Please note I cannot use Java, ABAP or XSLT mapping programme.
Can you provide me some hints on how to do this.
Thanks

Hi Chilla
This is how I am currently handling it. But my problem is
The number of UDF's keeps increasing if I have a fourth, fifth element to handle. I have to create new UDF for every new level added.
Is there a way I can do this with single UDF.
result.addValue(givenname(X));
X- will be the position and I can pass values as an argument to the UDF.
Again the problem here is when I have second argument to specify which value of input to pick up say for example givenname(1) or givenname(2)
The second argument expects an String[] array as argument and not string(when i assign a constant its a string).
So I cannot attach a constant to the second argument and pass the input.
Is there any functions that can return a String[] array as an output taking sting value as input.
Thanks
Satish

Need Clarification on Looping in Message Mapping.

Hi All,
I'm trying to implement the Dynamic emailing as explained in the Michals blog.
/people/michal.krawczyk2/blog/2005/03/07/mail-adapter-xi--how-to-implement-dynamic-mail-address
I have this partially working for the scenario I have.
XI will be receiving a ORDRSP IDoc from an external system and XI needs to do the following.
1) Check the value of <b> E1EDP01-ABGRU </b> equals to Z2. If any of the E1EDP01-ABGRU has a value of Z2, it should do the following
         a) Get the email address from the E1EDKA1-ILNNR and map it to the TO field as shown in the blog.
          b) Get the values of BELNR-E1EDK01, MENEE, VPREI, POSEX, PEINH, ABGRT from the E1EDP01 segment and concatenate them all and map it to the Content tag as explained in Michals blog.
I have this process partially working. The XI interface is only mapping for the first occurrence of E1EDP01 and not the subsequent occurrences of E1EDP01 which matches the criteria ( E1EDP01-ABGRU = Z2)
Any help in getting fixing this problem??
Thanks

Make sure to define multiple target messages in your message and interface mappings, for the mail package message definition (occurrence = 0...unbounded).
Also, in the logic of your message mapping, you need to create a new mail package message only if E1EDP01-ABGRU = 'Z2'. Use it like this:
ABGRU   ---   EqualS   ---   createIf   ---   Mail
Constant[Z2]

Henrique.

Set a variable in Adapter Module and read it during message mapping

Hi guys,
is there any way, how I could set some variable and store its value during the adapter module processing and read back this value in message mapping and use it? Without using a database or files.. I mean, some j2ee storage or something like that..
Thanks for your help,
Olian

Hi guys,
thanks for your answers.. just a clarification, what the problem is.
I need to validate a message in the adapter module, if it's digital signature is valid. If it is, I need to send back to the sender a return code (message) OK, otherwise ERROR. I can't modify the message (or dynamic configuration) as I'm using a WSS in the sender channel. The system doesn't allow me to change anything in the message, so I can't find out in the mapping what the validation result was. I then tried to do the validation directly in the message mapping, but I have some issues there with libraries or what, because the validation code, which works in the adapter module, doesn't work in the mapping java class. So my final thought was maybe I could validate the message in the adapter module and pass the result to the message mapping and then create an appropriate return message (in the mapping). However, I see no way of passing a value there. I'm stuck and have no Idea how to resolve the problem. Any hints guys?
Thanks a lot for your help!

DeletionIndicatior in Message Mapping

Hi Experts,
I have an requirement like i need to suppress the field and its value in the output structure. the file i need to drop at the output is an xml file.
the requirement is to drop a file with variable substitution method with
input file looks like this:
Field0 -- 000001
Field1 -- Sai
Field2 -- Krishna
Field3 -- AppleSystems
Field4 -- Bangalore
all are one to one mapping, in the output fille i require
Field1 -- Sai
Field2 -- Krishna
Field3 -- AppleSystems
Field4 -- Bangalore
Field0 is used for variable substitution for generating the file dynamically, so how could i suppress this field.
I can go with dynamic file naming but i am using multimapping here so i cannot use dynamic configuration i should go ahead with varibale substitution..
Second Clarification :
In the data type decleration we have Deletable Option check box across the field decleration
when we check it, In the message mapping we can see the DeletionIndicator,
May i know the purpose of this option
Your inputs are really appreciated..
Thanks,
--Sai

Sudeep,
Let we try this way. I'm sure you might have some existing mapping objects in IR.
Try to change that object(Description give some name) and activate again the object.
Reply your results whether you are getting the same error.
One sec before changing the object just test the mapping and change the object.

raj.

Error while opening Message Mapping

Hi All,
I have one MM in ESR, IDoc to EDI, it has been developed before, and the interface is working successfully.But when I open this MM in ESR, it given a STOP error with desc as 'For input string: ""'.
and then there is nothing displayed on Screen under Definition,Test and Functions tab of MM.The Signature tab content is visible properly.
I am working on PI 7.1.
Is this issue is because of version comapatibilty or missing object. Please provide your inputs to resolve this issue,
Thanks,
Ruchi

Hi All,
I have checked with my basis team, but they suggested that the patches can not be installed as this problem is happening with single message mapping.
When I open this MM, it gives the same STOP error :For input string: "". and when I click on Message Mapping -> Check button, it prompts a message 'Parameter #ParamName# has the invalid value null'.
Please help me to resolve this.As the mapping itself is not getting loaded, so not getting how to set this parameter value(if it is used in MM).

PI 7.11: IDoc Message mapping

Hi there,
I'm currently working on a graphical message mapping using IDoc HRMD_A06 as source structure (HR master data transferred via PFAL).
In my result structure I have to fill a field CostCenter with the following logic:
If field KOSTL (cost center) is filled in node E1P0315, map this field to CostCenter in result structure, otherwise take KOSTL of node E1P0001.
The end date (ENDDA) has to be '99991231' in each case.
This is how the result structure looks like:
<e>                       [1...1]
<CostCenter>            [1...1]
</e>
This is the simplified source structure:
<E1PLOGI SEGMENT="1">
<E1PITYP SEGMENT="1">                        [0...n]
     <E1P0001 SEGMENT="1">                     [0...n]
       <INFTY>0001</INFTY>                     [0...1]
       <ENDDA>99991231</ENDDA>                 [0...1]
       <KOSTL>0000012345</KOSTL>               [0...1]
    </E1P0001>
</E1PITYP>
<E1PITYP SEGMENT="1">                        [0...n]
    <E1P0315 SEGMENT="1">                      [0...n]
      <INFTY>0315</INFTY>                      [0...1]
      <ENDDA>99991231</ENDDA>                  [0...1]
      <KOSTL>0000024001</KOSTL>                [0...1]
    </E1P0315>
</E1PITYP>
</E1PLOGI>
How can I do the check if field KOSTL of node E1P0315 is null?
I've tried an existence check for the whole node (E1P0315->exists), but then it fails, because all E1PITYP nodes are processed.
I hope my problem is clear to you.
Would it be better to use another mapping type?
As I'm an ABAP developer, I would of course prefer some lines of code to this graphical drag&drop thing.
Thanks in advance!

Cheers, guys!
I did it now like that:
http://www.abload.de/image.php?img=mappingflknz.jpg
Click on the image to enlarge it!
The logic is as following (ABAP Pseudo-code ):
IF 0315_KOSTL and 0315_ENDDA are populated.
IF 0315_ENDDA equals '99991231'.
    map 0315_KOSTL to Cost_Center.
ENDIF.
ELSE.
IF 0001_KOSTL and 0001_ENDDA are populated.
    IF 0001_ENDDA equals '99991231'.
      map 0001_KOSTL to Cost_Center.
    ENDIF.
ENDIF.
ENDIF.
Is that a good way to do that mapping?
Do I also have to use the removeContexts function or is it ok like that?
Could I also do that with an ABAP mapping program?
Thanks in advance!

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..

How do I resolve error message "mapi was unable to load aplzod.dll"? Outlook2010 on Win7

Attempts to open Outlook calendar files (apparently located) on iCloud result in the error message "MAPI was unable to load the information service C:\PROGRA~2\COMMON~1\Apple\Internet Services\APLZOD.dll". Be sure the service is correctly installed and configured."
I am running Outlook 2010 on Windows 7. I have uninstalled and reinstalled iTunes with no apparent effect. Is this a problem with iTunes or Outlook, how do I resolve it?

That's part of my problem - I was getting the error message when I tried to click on iCloud in the Calendar portion of Outlook 2010. I don't know where it was generated (iCloud, iTunes, or as an add-in to Outlook).
After my original post I tried restoring my computer to a date when I knew this worked, the restoration worked, and I can access my calendar. So that problem resolved itself.
I do have another question, but I'll post it separately. Thanks for your response.

How to use the variables used in the message mapping

Hi ,
In the message mapping we can declare variables in the JAVA section , these variables could be used across the mapping .
I have tried using it but I am unable to retrieve the values assigned to the variables in one UDF into the another UDF .
Please guide me how to use the variables declared in the JAVA section in the message mapping .
Thanks
Anita Yadav

Anita,
I have worked on the Global variables and i found no issues. Make sure that the variable is declared in the Declaration Section and then initlaized in the Initialization section.
If you declare a variable in the Declaration Section ,
int i;
then in any udf you can use if directly. No need to re declare the variable in the UDF. If you do this, then it becomes a local variable.

Bhavesh

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.
