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
Errorcom.sap.aii.mapping.lookup.LookupException: Problem when calling an adapter by using communication channel CC_RFC_FM_Out_3 (Party: , Service: BS_FP_QR0_210, Object ID: b790616ffd613ba9ad31f8ac8a610754) XI AF API call failed.

Cannot resovle the Symbol error in UDF - Java mapping - RFC Lookup ?

Hi Friends ,
We are working on Java mapping - UDF for RFC Lookup . It is giving the Cannot resolve Symbol for all imported archive java class files even if we give again all imported files in import section of UDF we are still getting the same cannot resolve error .
We are using SP 12 of XI 3.0 . What could be the reason ?
Thanks.,
V.Rangarajan

Hi,
Can you try to open imported archive in IR and check if the path(folder structure like com.abc.xyz.etc) for classes is same as in import statement in UDF.Since we had experienced the same problem.
Thanks.

Issue with Jar files in UDF for RFC LookUp

Hi,
I am writing a UDF for RFC LookUp.
In the import statement of UDF, I used the JAR File : com.sap.aii.mapping.lookup.*;
The code inside the UDF uses LookupService.getChannel.
When I test the UDF, It shows an error ( ^ ) at LookupService.getChannel.
Could you please help me in understanding why Am I getting this error at all?
Thanks In Advance.

RFC lookup error

Hi all,
I am doing an RFC lookup to increment counter. I am facing a problem.
I followed the code written by Michael. https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a03e7b02-eea4-2910-089f-8214c6d1b439

The problem i am facing is that, i am not able to pass the IM_V_MSGID parameter to the function module.
The other 2 parameters i can pass. that is IM_V_FILENAME and IM_V_WRNO.
i am able to extract the message ID using
java.util.Map param = container.getTransformationParameters();
String MSGID = (String) param.get (StreamTransformationConstants.MESSAGE_ID);
and displayed it in SXI_MONITOR trace also using importanttrace.addWarning("Input value is "+m);
i got the correct MSGID in the trace.But the problem is that this value is not getting passed to the FM. Cos the table is supposed to increment the counter whenever the MSGID value changes.
I tried hardcoding the MSGID value to 'abc' or '123' like values but the same thing happended. The counter will not increment. The FM is working perfectly when i run it and change the MSGID values manually.
Thanks

Hi,
We have done this by creating an FM in XI ABAP stack:
FUNCTION Z_ZBXI_GET_PRE_MSG_ID.
""Local Interface:
*" IMPORTING
*"     VALUE(I_CURRMSGID) TYPE CHAR40
*" EXPORTING
*"     VALUE(E_PREMSGID) TYPE CHAR40
DATA: lv_currmsgid type SXMSPMAST-MSGGUID,
      lv_parentmsgid LIKE SXMSPMAST-PARENTMSG,
      lv_premsgid LIKE SXMSPMAST-MSGGUID.
lv_currmsgid = i_currmsgid.
select single PARENTMSG from SXMSPMAST into lv_parentmsgid where MSGGUID = lv_currmsgid.
e_premsgid = lv_parentmsgid.
ENDFUNCTION.
You need to call this FM through RFC lookup UDF in your mapping.
Let me know if it works for you.

PI 7.1 EHP1 RFC Lookup- Issue

Friends,
I'm seeing one strange issue in RFC Lookup behavior in my PI 7.1 EHP1 . Please give me some ideas for the same
Please see the below image for what I have done and what I'm seeing in the display queue.
http://www.flickr.com/photos/8764045@N06/4642237515/sizes/o/
To make it more simple - When I click on the Display queue on RFC lookup, I can see some 20 values with context changed. I removed my context and passed it to the UDF. When I check the input length in the UDF it's always giving 1, even though the display queue gives me 20 values.
Any ideas?
-Raj.

Exception in RFC Lookup

Hi Experts,
I have a query in Graphical RFC Lookup function.
I am working on Pi 7.1 and scenario is File to Idoc.
In the file, material number is coming, and I have to find out the corresponding Customer number from ECC table using RFC Lookup.
I know how to use RFC lookup.
But here issue is, if Customer Number is not maintained in the ECC table for the incoming material number, then exception should be thrown and processing should be stopped at that moment.
Please tell me how to throw this exception and hence fail the mapping.
-Supriya.

Hi ,
I guess you want to fail the message transformation at Message mapping level with Red Error in Monitoring , If LOOKUP return Nothing ...
What You can Do Is , Instead of RFC LOOKUP Function , Use UDF Based RFC LOOKUP , and Inside UDF you can easily raise exception.
Or
In Grapphical Message mapping pass the result from RFCLOOKUP To a 1..1 Target , if during transfermation if 1..1 node will not get any value , so mapping will get failed automatoicaly ..
hope the idea Helps
regards
PS

Message-Mapping: Use same RFC lookup for different target fields

Hello,
I need to apply an RFC Lookup which delivers a boolean flag back (true or false). This RFC lookup should be used for different target fields.
Is there a way to execute the RFC lookup just once and then store the result in an internediate variable that I can use for all futher checks for different target fields?
If this is not possible and I have to apply the RFC lookup for all necessary target fields is it then executed for each target field ? This is exactly what I want to avoid in order not to slow down performance.
The input parameter (=source field value) would be the same.
Thank you for your advice!

Exactly.
Here is a UDF example I have that you could adapt to your needs.
Set
public String setCounter(String a,String b,Container container){
/* Store values in global datacontainer
a: mapping value and return valueparameter
b: name for stored value parameter
GlobalContainer myGlobalContainer;
myGlobalContainer = container.getGlobalContainer();
myGlobalContainer.setParameter(b.toUpperCase(), a);
return a;
Get
public String getCounter(String a,Container container){
//write your code here
GlobalContainer gc = container.getGlobalContainer();
if (gc.getParameter(a) != null) {
return String.valueOf(gc.getParameter(a));
} else {
return "1";

SALERT_CREATE RFC in PI Mapping (RFC LookUps) to triggering Alerts:

Hi
I got a questions on using SALERT_CREATE RFC in PI Mapping (RFC LookUps) to triggering Alerts:
1) Should I import RFC (SAP PI server) into SAP PI ESB?
2) Should I maintain the details of SAP PI in the RFC receiver channel ?
3) Can I use this RFC for RFC Lookups like any other RFC (ECC)?
I really appreciate for your help on this
Thanks
Vasu

>>Should I import RFC (SAP PI server) into SAP PI ESB?
No, this is not required, in your UDF, you just need to build the same structure as the RFC expects so to make it easier, you can import the RFC and see how its structure looks like but the real RFC is not used in RFC Lookup.
>>Should I maintain the details of SAP PI in the RFC receiver channel ?
In general,you need to maintain the details of the SAP system where the RFC is stored, it could be PI/ECC or any other system.
Since you specify Alert information in this RFC lookup, the details will be of PI system.
>>Can I use this RFC for RFC Lookups like any other RFC (ECC)?
This RFC is used only to build the structure in UDF, it is not used in anything else.
Note: Since you have mentioned writing UDF, i am assuming you are using PI 7.0. If you are on PI 7.1, you don't need to write UDF for it. There is already a standard function for RFC Lookup.
Thanks

Multiple Fields in RFC call in UDF

In my Message Mapping I am calling a RFC using a UDF, this works fine but only for 1 field. Like in my BAPI I have 1 Field in the Input parameters. Does anyone know how to import more than 1 parameter? Here is some sample code from my UDF:
Calling the RFC, I specify this: <?xml version=\"1.0\" encoding=\"UTF-8\"?><p2:ZTEST xmlns:p2=\"urn:sap-com:document:sap:rfc:functions\"><INPUT_VALUE>4500014790</INPUT_VALUE></p2:ZTEST>
Where ZTEST is my BAPI name and INPUT_Value is my import parameter. My question is how would I specify more than 1 import parameter in my xml string? I tried <INPUT_VALUE1>4500014790</INPUT_VALUE1><INPUT_VALUE2>33</INPUT_VALUE3> but then it does not return anything..
String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace();
// filling the string with our RFC-XML (with values)
String m = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><p2:ZTEST xmlns:p2=\"urn:sap-com:document:sap:rfc:functions\"><INPUT_VALUE>4500014790</INPUT_VALUE></p2:ZTEST>";
RfcAccessor accessor = null;
ByteArrayOutputStream out = null;
try
// 1. Determine a channel (Business system, Communication channel)
Channel channel = LookupService.getChannel("ECDCLNT999","CC_ECD999_RFC");
// 2. Get a RFC accessor for a channel.
accessor = LookupService.getRfcAccessor(channel);
// 3. Create a xml input stream representing the function module request message.
InputStream inputStream = new ByteArrayInputStream(m.getBytes());
// 4. Create xml payload
XmlPayload payload = LookupService.getXmlPayload(inputStream);
// 5. Execute lookup.
Payload result = accessor.call(payload);
InputStream in = result.getContent();
out = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
for (int read = in.read(buffer); read > 0; read = in.read(buffer)) {
out.write(buffer, 0, read);
content = out.toString();
catch(LookupException e)
importanttrace.addWarning("Error while lookup " + e.getMessage() );
catch(IOException e)
importanttrace.addWarning("Error " + e.getMessage() );
finally
if (out!=null) {
try {
out.close();
} catch (IOException e) {

Hi Jan de Lange ,
Can you send the UDF code for the above. Even I was having the same problem ie., sending multiple values in the input file.
I want to send three PO numbers.
String m = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><p2:ZXI_GET_PO_DETAILS xmlns:p2=\"urn:sap-com:document:sap:rfc:functions\">
<PO_NUM>4500000005</PO_NUM>
<PO_NUM>4500000020</PO_NUM>
<PO_NUM>4500000021</PO_NUM></p2:ZXI_GET_PO_DETAILS>";

I am not aware of java coding so kindly make necessary modifications.
Kindly suggest what changes i need to do to execute perfectly.
Your help will be greatly apprecited.

Hi Venkat,
     If you use the JCO connection to get the value from RFC, it would be a problem in futherly like when you move this interface DEV to Q, then you need to change the connection parameters to establish the JCO connection.Same in Production environment too.It is not advisable to do JCO lookup. Go for RFC lookup as the link given by Farooq.
Create Reciever RFC communication channel and take the XML signature of u r RFC by importing that RFC under imported objects.Create an UDF, for this see the sample code which is exisitng in document to pass the Export parameter to RFC.
In this way u r RFC channel establish the connection to R3 and your RFC will execute and return the value.U just need to change the Reciever RFC channel parameters respective of environment.
Cheers

RFC Lookup error after moving to Quality from Development

Hi All,
For a scenario,I am using the RFC Lookup in message mapping.
I am not using it in a UDF but for directly for an target element....
The scenario was wrkng properly in development... but in quality it's not wrkng giving the following error....
RuntimeException during appliction Java mapping com/sap/xi/tf/_ABC_DEF_GHI_JKL_ Thrown: com.sap.aii.utilxi.misc.api.BaseRuntimeException: com.sap.aii.mapping.api.UndefinedParameterException: The input-parameter ISU_RFC_Receiver does not exist. at com.sap.aii.mappingtool.tf7.Transformer.start(Transformer.java:148) at com.sap.aii.mappingtool.tf7.AMappingProgram.transform(AMappingProgram.java:620) at

1.Message mapping-->Parameters (given the CC Name)
2.Operation mapping-->Binding (The binding parameters is specified)
3.In the interface determination.... choosen the Parameter for Operation mapping...
But still i am getting the above error..
Did any1 face the same prblm ever??? If yes may i know how u resolved???
Any inputs or suggestions is appreciated...

HI Michal,
I checked it thtz fine the same objects are transported to Quality without any modification...
But Still i am getting the same proble..

Hi all,
Below is the error when displaying the queue of the UDF.
RuntimeException in Message-Mapping transformation: Exception:[java.lang.RuntimeException: Error during MEI RFC Lookup] in class com.sap.xi.tf._MM_COND_A03_TO_MT_PRICELIST_ method callRFC$[com.sap.aii.mappingtool.tf3.CBufIter@32523252, com.sap.aii.mappingtool.tf3.CBufIter@32c732c7, com.sap.aii.mappingtool.tf3.CBufIter@333c333c, com.sap.aii.mappingtool.tf3.CBufIter@33c133c1, com.sap.aii.mappingtool.tf3.CBufIter@4bb84bb8, com.sap.aii.mappingtool.tf3.CBufIter@50ef50ef, com.sap.aii.mappingtool.tf3.CBufIter@51645164, com.sap.aii.mappingtool.tf3.CBufIter@51d951d9]
But when i test the mapping by passing input parameters the UDF responses with the output parameters and with the following error

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.

RFC lookup issue

Dear experts,
i have a file to file scenario where in the graphical mapping i have to write a RFC lookup to get some data from R3 system ...
i have written the following RFC lookup and it is working fine....
java.lang.;java.util.;com.sap.aii.mapping.lookup.;java.lang.reflect.;com.sap.mw.jco.;java.io.;
JCO.Repository mRepository;
// Change the logon information to your own system/user
JCO.Client mConnection = JCO.createClient(
    "500", // SAP client
    "test", // userid
    "temp", // password
    "EN", // language
    "gadrp700", // host name
    "03" ); // system number
// connect to SAP
mConnection.connect();
// create repository
mRepository = new JCO.Repository( "SAPLookup", mConnection );
// Create function
JCO.Function function = null;
IFunctionTemplate ft = mRepository.getFunctionTemplate("Zlookup_test");
function = ft.getFunction();
// Obtain parameter list for function
JCO.ParameterList input = function.getImportParameterList();
// Pass function parameters
input.setValue( a , "REC" );
mConnection.execute( function );
String ret = function.getExportParameterList().getString( "PAR" );
mConnection.disconnect();
return ret;
only problem is i have to hardcode the system details user id and pwd...i know that i can create a business service and RFC communication channel which i have done ...but i do not know what addition needs to be done in the code...can you pls help me regarding what addition needs to be done in code...
my business service name is : BS_test
RFC channels name is : RFC_channel.

Hi Ravi,
You are doing a RFC lookup using JCO connection. It is very old. So please see this help and do accordingly. In this you dont need to hardcode anything. For business system, you can do a UDF for getting the system name. So based upon the system name do a Fix Values. Only thing you need to maintain is the communication channel when you transport.
