Hi All,
We are working on a scenario which does a RFC lookup through the XSLT mapping.
While testing the XSL in he Interface mapping an Exception is generated:

BPM CBS - Exception during process compilation

Hi Experts,
I am developing a BPM process using SAP NWDS 7.2 and a remote NWDI track.
I have the following issue: When I edit my process, I create an activity for submit this changes. Later I try to check-in the activity and everything is okay, but when I try to activate it, the build finished with Errors. This is very unusual because locally I can to build this project without errors, and I can to deploy it directly to the Server without errors.
The summary of error in CBS Build Log is the following:

I checked the file "DCs/*****.**/compose/pre/pr/pm/_comp/src/bpmn/procesoprecontractual mdn.bpmn" and it doesnu2019t have any invalid characters like latin characters "á,é,í,ó,ú,ñ". I donu2019t know what other kind of characters are invalid or what is the exactly error.
Thanks,

Hello,
This issue is resolved now.
The problem was with the file system space on the Unix server(on which portal is installed).
The server administrators and the Basis team extended the disk space and issue got resolved.
Thanks for all your inputs.

Java Error in RFC Lookup in XSLT Mapping usinf Java helper class

The Lookup works fine when called one RFC at a time However my requirement is I want to do 2 Lookups.
Both Lookups works when done individually however when I call both lookups in one mapping I get following error "javax.xml.transform.TransformerException: DOMSource whose Node is null."

My Question: Am I doing anything wrong? Or Is it possible to call multiple lookups in one XSLT?
Thanks and Regards,
Atul

Hi Atul,
I had the same problem like you had.
The main Problem is that with the example code the request variable is created as NodeList object. In XSLT a variable is somekind of a constant and can't be changed. As the request object is empty after the first request the programm fails at the following line:
Source source = new DOMSource(request.item(0));
So I've created a workaround for this problem.
In the call of the template I've put the request as a parameter object at the template call:
<xsl:with-param name="req">
<rfc:PLM_EXPLORE_BILL_OF_MATERIAL xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<APPLICATION>Z001</APPLICATION>
<FLAG_NEW_EXPLOSION>X</FLAG_NEW_EXPLOSION>
<MATERIALNUMBER><xsl:value-of select="value"/></MATERIALNUMBER>
<PLANT>FSD0</PLANT>
<VALIDFROM><xsl:value-of select="//Recordset/Row[name='DTM-031']/value"/></VALIDFROM>
<BOMITEM_DATA/>
</rfc:PLM_EXPLORE_BILL_OF_MATERIAL>
</xsl:with-param>
With this change the request will be provided as a String object and not as a NodeList object.
Afterwards the RfcLookup.java has to be changed to the following:

Then you need to compile and upload this class and it should work.
I hope that this helps you.

RFC Lookup in XSLT Mapping

Hi,
I am trying to do RFC Lookup in XSLT.
I got this excellent mapping tool here at sdn:
RFC Lookup by Thorsten Nordholm Søbirk
But I am having problems when I uses this in a multi-record mapping. (many-to one) with lookup for every element.
Has anyone done IDOC with XSLT and RFC lookup (PI 7.11) ? Can you share the XSLT or experience?
Thx for sharing

Hi @ Fariah Ali
here is the mapping:
Inbound: IDOC HRMD_A07 (from ALE replication)
We only want to have Infotypes IT0001, IT0002, IT0050
Outbound:
<?xml version="1.0" encoding="utf-8"?>
<mt_I004_Time_Stammdaten>
 <Datensatz>
 <PersNr>PERSNR</PersNr>
 <Name>ENAME</Name>
 <Eintrittsdatum>BEGDA</Eintrittsdatum>
 Austrittsdatum>ENDDA</Austrittsdatum>
 <BeschArt/>
 <Gueltigkeitsdatum/>
 </Datensatz>
</mt_I004_Time_Stammdaten>
thx holger

Java RFC lookup from XSLT mapping

I tried to implement a generic Java RFC Lookup class to be called as a Java extension from my XSLT mapping. I found the How-To-Guide "Easy RFC lookup from XSLT mappings using a Java helper class" ([Easy RFC lookup pdf site|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14?quicklink=index&overridelayout=true]) and tailored the source code to my XSLT program. I am getting the error "Variable '$inputparam' has not been bound to a value". Can anyone tell me what I am missing? I am not familiar with java at all, and only moderately familiar with XSLT.

> I am getting the error "Variable '$inputparam' has not been bound to a value". Can anyone tell me what I am missing?
At runtime the variable does not get value. You need to assign value to the variable inputparam. Just curious why dont use the RFC lookup graphical which is very easy and no need to handle java programming. You need to configure just reciever RFC communication channel.

Code Sample: Easy RFC Lookup From XSLT Mappings Using a Java Helper Class

Hi everyone,
This is just a shameless plug for my article: <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14">Easy RFC Lookup From XSLT Mappings Using a Java Helper Class</a>. I hope you're interested in reading it, and I welcome your comments in this thread.
Kind regards,
Thorsten

Hi Stefan. Thanks for your post. I have already done that. It still does not work. As a base for my java helper class I have usesd Thorstens code.
The problem is quite confusing. I will try to ouline both issues here.
First of all, when try to test from within the Operation Mapping, I always get a java error saying it cannot find the communication channel (it is there and working because I have tested it with the RFCLookup in graphical mapping). I have found a way to work around this, and that is to uncheck the "Use SAP XMLToolkit" checkbox --> switch to test tab, enter my ReceiverService in the parameter tab (header parameter) --> switch back to Definition tab, check the "Use SAP XMLToolkit" checkbox --> switch to Test tab and run the test. Then the XSLT and call to java helper class will work. Of course this is not really something you want to do all the time. Maybe there is a bug.
Secondly, it never works when I try to do it "live". I am using a file adapter to pick up one file, convert it and a file adapter to drop the converted file. I get the following error code in SXMB_MONI.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Using an XSLT without a call to a java helper class, works just fine.
I am totally at a loss here. Any more input would be much appreciated.

I am SAP XI 3.0 SP-9

Hello,
I have the same issue as stated above.
At runtime sometimes the mapping fails however when executing the mapping from ESR (test operation mapping) with the same payload it is executed succesfully (lookup is to system that is the senderservice of the scenario).
Anybody a clue.
Also clearing mapping cache etc. did not solve the problem.
Thanks,
Emile

Hi Mahesh,
I have tested the RFC and i have taken the input from the function module...the RFC is working good, the comm channel is good...
below is the error when i tested my mapping... (the output from the function module is also correct)... i need to use hashmap to store the output...

RFC lookup - Error executing simple lookup

Hi guys,
Something weird is happening.
I'm using a RFC lookup to get some parameters and I'm using the same generic UDF that I usually take on different projects.
But this time I'm getting the following error:
com.sap.aii.mappingtool.tf3.MessageMappingException: Runtime exception during processing target field mapping /ns0:Messages/ns0:Message1/MessageStatus/StatusInformation/Status. The message is: Exception:[java.lang.StringIndexOutOfBoundsException] in class com.sap.xi.tf._mmEOrdersRetailRequest_ method SAPRFCLookup$[RFC_Receiver_LookUp_SAP, MARA, MATNR EQ '000000000000000123
' , VPSTA, TST002, com.sap.aii.mappingtool.tf3.rt.Context@1f231f23]
Do you have any idea?
I've commented my RFCLookup code and the error jumps up on the getRfcAccessor line.
 try {
// 1. Determine a channel (Business system, Communication channel)
 com.sap.aii.mapping.lookup.Channel channel = com.sap.aii.mapping.lookup.LookupService.getChannel(BusinessService,CommChannel);
// 2. Get a RFC accessor for a channel.
 accessor = com.sap.aii.mapping.lookup.LookupService.getRfcAccessor(channel);
The channel is well created on the IDirectory, associated with the correct BusinessSystem. I can check on the CommunicationChannel Monitoring that the channel opens the JCO connection correctly..
However if I change this RFCLookup by a JCOLookup everything works smoothly...
I've done this thousand times but now I'm not able to get the problem...
Can you guys help?

Hi Sridevi,
Sorry for the late reply but the problem continues...
We're using Netweaver 7.0 SP 14, patch number 0026
Thanks for your interest.

Urgent: RFC Lookup for BAPI in XI

Hi,
I am trying to call a BAPI that exists in XI system,in the Message Mapping in same XI system.
If I run the BAPI,it is working fine.
But if I call this in XI Message Mapping using RFC lookup,it returns garbage.
I am not getting any RFC error.
Can anyone please tell me what could be the reason for this.
Thanks.
Best Regards,
Shweta

Hi Shwetha,
Please refer the below weblog:
RFC lookup using JCO (without communication channel)

try{
final String SAPRFCNS = "urn:sap-com:document:sap:rfc:functions",

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
factory.setNamespaceAware(false);

RFC LookUps Basics

Dear ALL,
I need some basics on why we need RFC LookUps..
where it is used in real time projects with an example..
and different types of RFC lookUps..with some good example
Regards
Shakif

Hi sakhif,
    SAP provides an API( Application Interface ) for performing lookup or ( data Access) during runtime to enchance mapping by accessing the relevantdata that is useful in validations and present that accessed data that is relevant for the receiver end .It plays very important role in B2B kind of scenarios where in we need to refer the data that is not a part of pay load but still need it to process the payload.
(Ex: During the B2B scenario ,when a purchase order id being sent from source to target ,you see a field called purchase order type and the values in the sencer side contains only (OR or ZZ). but the receiver wants the definition of the particular (OR or ZZ).In this case You apply the look up , get the definitions and make them appear in the receiver data.
so after applying look up the data transforms like this.
SENDER Side       RECEIVER Side
OR       -
> Original (original order)
ZZ        -
> Mutually Defined .
Lookup API for data enrichement in mapping programs.
With the Lookup API you can call remote application systems via adapters during the execution of a mapping program. You can use the Lookup API to read data from the application system or to execute an existing mapping on the application system. The call to the application system is synchronous. Lookups are possible via the central adapter engine. The Lookup API supports the RFC, JDBC, and SOAP adapter.
If you want to use an adapter of a third party vender, then the adapter must fulfil the following preconditions:
The adapter must support synchronous calls.
The adapter must not use information of a Receiver Agreement.
The following link will help you out in understanding more on RFC look up.

RFC Lookup in UDF

hi gurus,
i'm facing a weird problem, i have implmented three scenarios IDOC - > FILE, inside each mapping i created an UDF
that call an RFC function that brings me an accounting value, the rfc call another FM : LAST_DAY_IN_PERIOD_GET.
of course i give the UDF some parameters the BS, the name of CC.
my probleme is in quality environment, randomly in some of those three scenarios, the rfc brings me a null value.
and i dont why and how to solve this issue.
thanx in advance for your help.

this the error
