Local lookup in message mapping

Hi all,
I've a table on the SAP PI system filled with data. From my message mapping, I want to do a lookup.
What's the best way to perform this lookup.
Again, this is a local table. So not a table residing on the SAP ECC system.
Thanks a lot.
Dimitri

Hi,
>>>I've a table on the SAP PI system filled with data. From my message mapping, I want to do a lookup.
What's the best way to perform this lookup.
the best/easiest way would be to use ABAP mapping (right after your message mapping - as in interface
determination you can have many mappings)
just to do the lookup in XI table (in abap mapping you juse use a select to get this data)
so map the data in message mapping
then do the lookup in abap mapping just for this one field

Raising exceptions in database lookups in message mapping

Hi
We have been able to successfully do a database lookup from within a message mapping - thanks to weblogs already existing out there. However, we have requirement that states that - if the lookup fails ( failure to connect to DB / data retrieved is null ) , then the mapping should fail - and an exception raised.
How can we go about doing this from within the java code - of the mapping lookup ?
Any correct pointers /solutions to achieve this will be rewarded rightaway. Thanks in advance for your time.

Hi,
you can use Alessandro's way:

Soap lookup in PI7.31 message mapping

Hi All,
I have a soap lookup created in UDF in PI message mapping
I am taking material id from the source structure and use it as input parameter for the lookup webservice
Here is the UDF code which takes material number and returns the internal id
AbstractTrace trace = container.getTrace();
String matintid = "";
try {
//instance the channel to invoke the service.
Channel channel = LookupService.getChannel("BS_Bus","CC_SearchLookup");
SystemAccessor accessor = LookupService.getSystemAccessor(channel);
// The Request message in XML. THIS IS THE LOOKUP SERVICE
String SOAPxml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><searchTM_MATERIAL>xmlns:ns0=\"MDM_MAT_Search_MDM"><query><criteria><fTX_MATERIAL><constraint><value>"
+a
+ "</value><expressionOperator>equals</expressionOperator></constraint></fTX_MATERIAL></criteria></query><reposInfo><repositoryName>REP_MATERIALS</repositoryName><serverName>mdm6765</serverName></reposInfo></searchTM_MATERIAL>";
InputStream inputStream =new ByteArrayInputStream(SOAPxml.getBytes());
XmlPayload payload = LookupService.getXmlPayload(inputStream);
Payload SOAPOutPayload = null;
//The response will be a Payload. Parse this to get the response field out.
SOAPOutPayload = accessor.call(payload);
/* Parse the SOAPPayload to get the SOAP Response back. */
InputStream inp = SOAPOutPayload.getContent();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
/* Create DOM structure from input XML */
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(inp);
NodeList matlist = document.getElementsByTagName("tM_MATERIAL");
Element material = (Element) matlist.item(0);
NodeList recidlist = material.getElementsByTagName("recordIdentification");
Element recidnode = (Element)recidlist.item(0);
matintid = recidnode.getNodeValue();
trace.addInfo("matnid is" + matintid);
} catch (Exception e) {
trace.addWarning("Error" + e); }
trace.addInfo("Service XXX success executed");
return matintid;
This is giving a java null point error
Errorjava.lang.NullPointerException: while trying to invoke the method org.w3c.dom.Element.getElementsByTagName(java.lang.String) of a null object loaded from a local variable at slot 16
Any idea whats going on? I am able to get response for the webservice using SOAP UI

Hi Mike,
What I suspect is, you get a null pointer exception because the XML tag name which you are trying to retrieve, has a namespace. Could you please instead try to use:
getElementsByTagNameNS(java.lang.String namespaceURI, java.lang.String localName)
 Returns a NodeList of all the Elements with a given local name and namespace URI in document order.
Let us know if it works.

Data lookup in R/3 database from message mapping

Can somebody help in rectifying the problem?

Hi,
can u post the java code which u have used in mapping.
There is a doc in XI-Articles. "How to Perform SAP Data Lookups Within XI Mappings" By Jerome Delune 16 October, 2003. Try looking at this article and do ur mapping.
Hope this helps you.

Lookup value mapping table through message mapping.

Hello All,
I am working on a graphical mapping (message mapping). When trying to map the source message to the target message, I need to find out it a particular key exists in the value mapping table. Depending on the result, I need to map different source fields to the target field.
Is there any inbuilt function which will allow me to do a lookup on a value mapping table, or is it possible to lookup a value mapping table from a UDF?
Please help!
Warm Regards,
Keerti

RFC Lookup's in message mapping fail with RuntimeException for no reason

Hi guys,
We have developed interfaces that execute a lot of RFC's from Message Mapping, by making use of RFC Lookup API.
In ID, in the corresponding RFC Receiver Communication Channel we have set the number of maximum connections to 100.
However, when a big number of Idocs with lots of items is sent to XI some messages fail in XI because mapping fails with a runtime exception that is not correct, since there is a return value found from the execution of the RFC function. And when I am testing the mapping in Test mode of XI IR, the mapping is executed successfully.
Do you think that by increasing the maximum number of connections in Communication Channel, it will take effect?

Lookup into R/3 table during Message Mapping

Hi all,
I have a field in my source message that I need to convert. The corresponding values are stored in an R/3 table. I could use a 2:1 mapping in a BPM to merge an RFC call reading the table with my mapping, but I was told that this can be done without using BPM.
Can anyone describe me this ?
Thanks in advance.
Best regards,
Julien

Hi Julien,
Starting SP13 you can perform RFC lookups within your mapping using standard RFC API.
Check this michal's document for the same...

SOAP lookups from withing message mapping

Hi
 We are doing a call to a webservice from within a udf in a message mapping using the SOAP API described in one of the blogs in SDN. We are using a soap receiver communication channel to make this webservice call -
We see activity on the communication channel monitoring - indicating that there is a call going out and a response coming back from the webservice. But there are no details shown on the payload in communication channel monitoring. We do not see this webservice lookup as a message on the adapter engine either ?
Is there any place from within XI runtime environment we can get a hold of the message going out to webservice call and the return from webservice ? We are facing problems in the webservice not doing the required action desired and hence this question on visibility of the call to the webservice.
Thanks in advance for your time.

My udf is basically makes a call to the webserservice lookup method ( line - CallCentralMonitoring.LogToCentralMonitoring( "IN130.10", "COMPLETED"); ) - the definition of CallCentralMonitoring class is given below after the udf

Graphical message mapping examples for JDBC and RFC lookup

hi, can any body provide me graphical message mapping examples for the "JDBC Lookup" function and "RFC Lookup" function?
I'm now studying the graphical message mapping and want to try those 2 functions. thank you.
I expect the examples to be simple enoung, not need to set up much.

When I open IB, it display a screen titled with "Configuration: Intergation Builder", I did not find "software component version" node on the left tree.

The Prerequisites state:
The JDBC channel to be used for the lookup must be configured and activated in the Integration Directory.
The definition of the table used for the lookup must already be imported into the ES Repository as an external definition
But I don't know how to create a JDBC channel and define the table.

Message Mapping fails because of RFC

Guys,
1) I have some messages failed in SXMB_MONI because message mapping for those interfaces was not executed successfully. In trace I can see the following:
"com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=A ASHOST=121.12.2.15 SYSNR=02 GWHOST=121.12.2.15 GWSERV=sapgw02 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner not reached (host ?, service ?) TIME Wed Jul 11 07:20:27 2007 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -10 COUNTER 1024</Trace>"
I realize it is a network connection problem, but..
Any ideas?
2) Actually, in my mapping programs I have to perform many RFC's to both XI and target/source SAP systems, in order to get some information. The techique that I am using for RFC's is through Java's com.sap.mw.jco.* package. And I connect to systems by giving the IP address, system number, username and password of the systems and then I execute the remote enabled function modules.
However. when I have many RFC's some of them fail, maybe because the maximum number is reached. And then I have to manually restart them from SXMB_MONI and they are successfully processed.
Any ideas?

But you said you call many RFCs inside XI, right?
The proper way of doing it is not using JCo directly, but using Mapping Lookup API instead. In this way, you won't need to maintain the connection details inside the code, but in the communication channels.
Check this out: https://help.sap.com/javadocs/NW04S/current/pi/index.html (lookup api).
There are some code examples within the classes (for example, RfcAcessor).
I think there is also a SDN documentation by Michal Krawczyk regarding RFC Lookups.
Just search for it.

Henrique.

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.

Message Mapping error in UDF

I am receiving errors when trying to activate my MM. I believe the issues are in one of two UDF's. These UDF's do work in another MM without error. Below are the error's and UDF's.

Any help is appreciated.

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.
