Regarding Message Mapping

Hi All,
The problem is I have created 2 Message Mappings and Two Message Interfaces
Two Messages Mappings and Message Interfaces are activated successfully, my question is which Message Mapping will execute among them(Message Mapping). If it Executes latest one Message Mapping ok, if I want to Execute Old one how can I execute that. I dont know whether we can create more than one Message Mapping, if it is possible here then can I Execute any one among all these Message Mapping help me in this problem.
Thanks & Regards,
Ashok.

hi,
in your scenarios your mappings
are executed on the basis of the interface mappings
one interface mapping can have a few message mappings
that will all be executed :
/people/michal.krawczyk2/blog/2005/11/01/xi-xml-node-into-a-string-with-graphical-mapping
you always use interface mappings (in directory)
so you need to check how which message mappings
are included in your interface mapping
to find out which will be used in your scenarios

michal

Regarding Message Mapping in JDBC Scenario

Hello Experts,
I got struct up in message mapping. In message mapping we can able to see different types of Functions. So I need some clarifications on it. Functions are available like...
Conversions
Boolean
Node Functions
Constants
Date

Regarding Message Mapping Logic ...!

Hi Experts ,
I am working on the the below requirement JDBC to IDoc scenarion in the mapping i need the below logic
based on the existence of the Transaciton ID . the idoc followed by the segments should be created . for ex
If Interface_Trasaction_ID= 456 THEN Idoc 1 followed by Segments and line items
 E1BPACHE09,
 E1BPACCR09
 E1BPACCR09,
 E1PACEXTC .
 Field value=456
If Interface_Transaction_ID =457 THEN Idoc 2 followed by Segments and line items
 E1BPACHE09,
 E1BPACCR09
 E1BPACCR09,
 E1PACEXTC .
 Field value=457
To satisfy the above logic i have mapped Transaction id > SplitByValue->CollapseContext--->Idoc
But the same Mapping Logic is not working when Sender payload is triggred having Repeated Transcation_Id value ias given below if Transaction ID= 456 ,
 Transaction ID= 457,
 Transaction ID= 457,
 Transaction ID= 456 .
then output should have only 2 Idoc Followed by segments where Field Value will be 456, 457
I have mapped Transaction id -->Field Value .
let me know how can achive the above logic ...!!

Hi Aziz,
you can use UDF
Transaction IDRemoveContext-->sortUDF- SplitByValue->CollapseContext--->Idoc
public void removeDuplicate(String[] Value, ResultList result, Container container) throws StreamTransformationException{
String temp = Value[0];
result.addValue(Value[0]);
for(int i=0;i<Value.length;i++)
 if(!(Value.equals(temp)))
 result.addValue(Value);
 temp=Value;

Message Mapping- 3 problems

Hi,
1)I need some information regarding Message Mapping. I need to map the field TDLINE of segment E1EDKT2 of IDOC ORDERS05 to the target fields. But based upon the index number of the record of this segment, I must map it to different fields (eg.E1EDKT2[10], E1EDKT2[3]). How can I incorporate this in Message Mapping?
2)And one more scenario is as follows.Use PARTN if exists or use LIFNR to map to target and it must satisfythe conidtion PARVW = AG. Should we need Java code or can we achieve this using two 'If' conditions.
3)We are looping at a source segment and it has multiple occurances.How to create multiple segments in target based on condition.
Can anyone help me.
Thanks,
Srinivas

You can use the index function (with SP13):
E1EDKT2* - index
                  equalS
    constant(10) /
                         ifWithoutElse - target
TDLINE - removeContexts /
check the correct context

Sure you can chain if statements:
        PARVW
              equalS
constant(AG) /
                     ifWithoutElse
              PARTN /
                   PARTN - exist - if - target
                              LIFNR
This mapping assumes, that PARVW = AG is available, when PARTN is available.
> 3)We are looping at a source segment and it has

Here is a pattern:
condition - createIf - target
condition has to be a queue of true and false with the same occurrency as source.
All sub nodes of source are now arranged correctly under the target node.

Message Mapping for multiple item levels

Hi,
My query is regarding message mapping
Example of source data structure & Target data structure
Source data Structure
<item>
 --<no>1</no>
 --<address/>
 --<ITEMS>
 ----<item>
 ------<Name>a</Name>
 ----<item>
 ------<Name>b</Name>
<item>
 --<no>2</no>
 --<address/>
 --<ITEMS>
 ----<item>
 ------<Name>c</Name>
 ----<item>
 ------<Name>d</Name>
Expected Target data structure
<Item>
-- <no>1</no>
-- <name>a</name>
<Item>
-- <no>1</no>
-- <name>b</name>
<Item>
-- <no>2</no>
-- <name>c</name>
<Item>
-- <no>2</no>
-- <name>d</name>
How I can map the '<no>' field to target '<no>' field to repeat value until to second sub item level occurance complete ?
Thank you
Sateesh

Hi Sateesh,
Please see the solution below.
The are 2 contect changes you need to do on field level. Right click and go to context and select your context you need.
Context on ITEMS - Should be on Root Structure(In my mapping it is MT_Multiple_Item_Level_Source)
Context on Name - Should be on Item (The first Item Tag)
Good Luck.

Jannus Botha

Query Regarding Multi-Message Mapping in Interface Mapping.

Hi All,
I've a query that can we use Multi-Message Mapping in Interface Mapping if:
One mapping structure is simple one-2-one mapping and
Second mapping is calling a stored procedure.
Please give me some links if the answer is YES.
Thanks in Advance.
Regards,
Sreedhar.
Edited by: Sreedhar Av on Oct 12, 2009 1:26 PM

Hi,
Your question not clear buddy..what i understood is..
If you want execute multiple message mappings in Interface mapping we can ,just add two mapping programs in interface mapping.first mapping program output is input to the second mapping program.
If first mapping program is very simple,if you want to execute stored procedure in second level mapping write used defned fun ction to conect to data base or create JDMC receiver communication channel ,cal the communictaion channel in udf.write stored procedure in UDF.
SEARCH for more info in sdn how to perform DBLOOKUPS.

Regarding nodes shown in red colour in message mapping under test (tab)

hi all.
i just want to confrom one thing.
i just created a file to rfc scenario and when i was tested and look in sxmb_moni its showing like the message was sucess but when i ltested in message mapping in design there were some nodes in sender Message type which were displayed in red colour.
and when i look in runtime workbench the message is showing like system error.
so can you guys tell me what could be the reason for this.
waiting for your response.
bye.
regards.
seeta ram.

hi rinku .
i think you havent understand my problem.
here the message in moni was showing as succes but when i tested the same message which was in moni in message mapping (design) there were some nodes which were in red colour and these nodes are not populated to reciever message type .but it was in sxmb_moni with all the nodes .
what could be the reason for this.
can u tell me fast and i case if u still havent understand the Q u can ask me.
waiting for your response.

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.
Best regards,
raj.

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

To get exception value in Message Mapping

Hi folks,
I would like catch bpm step exception in one message mapping, for example:
I have create on ccBPM using one block, in block i have createad "ex" exception variable and set ex in all step (send and transformation), i have created one exception branch in block using "ex" exception.
How can i get "ex" value and pass for one message mapping ?
In MM how can i get text values from excpetion ocurred in ccBPM ?
Im am trying using Global Variables but not found any parameter of exceptions.
Can anybody help me, please?

hi,

Regards,

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.

Additional message mapping in the operation mapping-use

Hi Friends,
I could find the option for adding more than one message mappings in the operation mapping(Interface mapping). What is the actual purpose of it. when it is used. If there is any blogs regarding the same. refer any link for the same.
Regards
Prem

Hi Prem
Refer the blog provided by Sarvesh
What is the actual purpose of it. when it is used. If there is any blogs regarding the same
You can use more than one mapping programs for requirement where your message mapping cannot generate the desired structure you want or you want to do some transformations in a sequence for meeting your requirement.
Example: You want to generate a excel sheet as a mail attachment but you have to read a flat file. What you can do here is you can read the Flat file in a single string variable itself. Use XSLT mapping1. Now in a sequence using XSLT Map2/Java mapping program to convert to excel and send as attachment over email

Error while forming Structur in Message Mapping.

Hi ,
I have taken source payload from Moni and tried to test the Message mapping.
When i paste the Pay load in Test tab,under XML, my structure is getting well formed., But 3 feilds from structure is showing in Red color.
Please advice
Regards
Dinesh

Hi Dinesh,
Please cross check with filling the values into the test tab and display it in source xml format and copy in notepad and compare with the payload data there must be some tag problem.
Thanks!
