Message mapping in sap pi 7.3

Hi all,
I am using SAP PI 7.3. In ESR, I have declared one source data type & message type and one target data type & message type. I have also completed message mapping. But in message mapping, If I do right click on the target message type, I am getting one option "Add variable" in the context.
Can anyone tell me what is the use of it?
Thanks & Regards,
Moumita

Hi Moumita
This is mainly used to store some values in it and then use it later in the same mapping.
For example suppose there is a field which contains amount and it occurs in many times in the source structure.
So we can populate the sum of all this fields into this variable and later used that for populating any target field.
Another example is suppose we want to make an RFC look up in PI to store some data in ECC tables.
In that also we map the RFC look up function to this variable.
This variable will be not present in the map output.

RuntimeException in Message-Mapping (com.sap.aii.utilxi.misc.api.BaseRunti)

HI,
We are facing a very strange problem , during runtime we are facing the below mapping problem ,

But when we have downloaded the XML from SXMB_MONI and tested the mapping it works fine , only in the run time we are facing this problem , funny part is the same scenario worked fine yester day itself (end-to-end).

Hi
please chech whether the data in the input file is according to the format or not.
for this you go to sxmb_moni,take the input payload from the moni and test with that payload and you will come to lnow where is the error.
if you still have the problem please relly me back

Message-Mapping transformation Error(Soap - XI - SAP)

Hi
We have a sceanio
Soap <-> XI <-> SAP
We could see the RFC return message from SAP but while trasforming that message to SOAP response ,we are getting the following error. We have manually run the response mapping program, it is executing fine.
<SAP:Stack>During the application mapping com/sap/xi/tf/_MM_GR_GetTODetails_Response_ a com.sap.aii.utilxi.misc.api.BaseRuntimeException was thrown: RuntimeException in Message-Mapping transformatio~</SAP:Stack>
Could anybody please help us.
Thanks
Ramesh

Hi
Thank you so much for your promt responses. I could get great inputs from your responses.
It is the problem with the RFC return message structure. In one of the segment it was defined mandatory but the RFC is not populating that segment data.
Appreciate your help.

Pls can anybody guide me as to what can be the probable error.

Hi all,
Thanks for ur prompt responses.
I followed the blog and performed testing of the mapping.
The XML with which i tried was as follows:

this gave the following error:
Cannot produce target element /ns:CondRec_MT/ConditionRecord. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd
But when i removed the tag 'RECORDSET', it works fine and output gets genersted.
My datatype has no such field called recordset.
The adapter generates it on its on.
How do i solve this issue.

Hi Deviprasad,
It looks like a mapping error, test your mapping in IR with the payload from SXMB_MONI. You can refer michal's weblog on <a href="/people/michal.krawczyk2/blog/2005/09/16/xi-how-to-test-your-mapping-in-real-life-scenarios to test your mapping (in real life scenarios)</a>
In other words you copy the XML message from monitoring and exectute the mapping in Integration Builder with maximal trace to get the reason.

Hi,
I am not able to see any namespace declaration in your input XML, wheras normally you would have defined an interface mapping using a namespace. But, I don't know whether that is the problem here.
Can you check the TRACE message for more details. The TRACE message normally tells you the steps it has performed and where exactly it has failed.
Warm regards,
Venki.

Beautiful..Thx...
I will try out and let you know Amit
One more request.
I have to do this mapping first and use it in receiver interfaces of ICO using an operation mapping and inbound interface as usual.
Now, I have to add 2 more inbound interfaces in the receiver interfaces and maintain order at Runtime to execute the above mapping first always and then execute the 2 additional inbound interfaces based on some condition.
The condition has to be something like this (source structure <flag> field value dependent condition)
/Material/row/flag = 'N'       call the second inbound interface to execute a operation mapping
/Material/row/flag = 'N'       call the third interface to execute another operation mapping
Now the complexity here is:
If the source structure is like this below
<Material>
<row>    1....unbounded
<Mat_ID>123<Mat_ID>
<Desc><text</Desc>
<uom>EA</uom>
<plant>AB</plant>
<org>XY</org>
<flag>N</flag> -- this is the flag field for the first material
</row>
<row>
<Mat_ID>123<Mat_ID>
<Desc><text</Desc>
<flag>N</flag> -- this is the flag field for the first material again
<uom>ST</uom>
<plant>CD</plant>
<org>FG</org>
</row>
<row>
<Mat_ID>345<Mat_ID>
<Desc><text</Desc>
<flag>N</flag> --this is the flag field for the second material
<uom>XY</uom>
<plant>DE</plant>
<org>ZX</org>
</row>
and so on
</Material>
The target structure for the additional 2 inbound interface are shown below
2nd inbound interface target structure
<Material>
<Mat_ID>123</Mat_ID>
<flag>N</flag> - constant value 'N'
<Mat_ID>345</Mat_ID>
<flag>N</flag> - constant value 'N'
</Material>
3rd inbound interface target structure
<Material>
<Mat_ID>123</Mat_ID>
<flag>Y</flag> - constant value 'Y'
<Mat_ID>345</Mat_ID>
<flag>Y</flag> - constant value 'Y'
</Material>
first question: how do I write a condition for checking the source structure <flag> field value for every unique material ?
second question: what would be the message mapping and operation mapping for the 2nd and 3rd inbound interfaces?
thx
mike

Problem in message Mapping SAP PI 7.1

Hi Experts,
I have a problem in my Message Mapping,
Design: [Design|http://www.life-4-music.de/prob.jpg]
Messagemapping: [MappingTest|http://www.life-4-music.de/probII.jpg]
The Problem is, that ElementC from SourceMessage occours "0 to n" times in Element A, but I need to check every ElementC in ElementA to TargetElementA with a IF Statement.
I tried a lot of things, like change the CONTEXT of the ELEMENT or use SPLIT BY VALUE but without success.
Rgds,
Steffen

Hello, thanks a lot for the fast awnser. I tried this allready to change the Context of the Elements "system" in this Mapping: Changed Context
For Example in one field I check for Entry "ERP" in Source Field "system" , if "ERP" is in the first ELEMENT then it will be mapped correctly: Example ERP works
But If "ERP" is in an element below, then it doesn´t work, so it seems to be, that he only map the first occurrence of the Elements. : Example SCADA don´t work
Here is the View of the QUEUE from the don´t working Example: Show QUEUE of not working Example
maybe u have a tip for me again , because I´m allready desperate
Thanks a lot.
Rgds,

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.

Message Mapping activation error-Source code has syntax errors in UDF

Hi all,
I wrote a small UDF for sum of 2 numbers:

public String getsum(String a, String b, Container container) throws StreamTransformationException{
int c = Integer.parseInt(a);
int d = Integer.parseInt(b);
int e = packageDemo.getSum(c,d);
return e+"";}
In imported archives, i imported pack.jar
In D:\udf , I have packageDemo.java, packageDemo.class, aii_map_api.jar, pack.jar(has the other 3)
packageDemo.java :-
package udf;
public class packageDemo{
    public static int getSum(int a,int b)
        int c= a+b;
        return c;
Did i miss anything?? Icant activate message mapping for 2 errors:-

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,
Durga

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.
