Sending a table to remote RFC in Java UDF

Hello,
 
We use the API "com.sap.aii.mapping.lookup" often to make RFC calls from a UDF and return data. We typically create an import parameter in the Function Module and pass the value into the RFC. We now need to send in an unlimited number of values so we understand that instead of the import paramter we need to use a table. The problem is we get an error when we build the XML in our UDF and try to call the RFC. We tried wrapping the values in item nodes and several other approaches but we are not sure if we can populate a table via XML and make the RFC call.
 
Example of what we tried:
 
String sRfcxml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns0:ZCAE_MX_CONTRACT_ROUTING xmlns:ns0=\"urn:sap-com:document:sap:rfc:functions\"><E_ZCAE_COCODE><item>0445</item></E_ZCAE_COCODE></ns0:ZCAE_MX_CONTRACT_ROUTING>";
 
Regardless of what we try we get the following error during the call:
 
error of "RuntimeException in Message-Mapping transformation: Exception:[java.lang.RuntimeException: com.sap.aii.mapping.lookup.LookupException: Exception during processing the payload.Problem when calling an adapter by using communication channel RFC_RCV_ORGDATA (Party: , Service: ValidateXIData_BusiServ, Object ID: d5401e52ad1039df96f02bde53b23c06) XI AF API call failed.

Now if we do not pass any data or use an import versus table parameter in the function module it works just fine.
 
We know we can work around this by using an import parameter and stringing the values together with a delimiter and then breaking this apart in ABAP but we are looking for a cleaner solution.
 
Any thoughts?

Not sure what's wrong, but are you sure your "stringed" XML document matches the expected RFC structure ? Btw, I'd replace (though it could be considered as a cosmetic change) to replace "ns0" with "rfc" in your namespaces declaration, it's what you'll see in all imported RFC objects in XI/PI

Error importing RFC / idoc despite following note 769356

We have been experiencing a number of problems where we cannot import RFC / idocs in the integration repository. The BASIS team have followed note 769356 and originally this solved the problem but meant that we reverted back to old screens in the Integration Builder and some German texts in the Integration Repository.
Current patch version is Support Stack 4
To get to this point the following steps were followed:
Undeployed com.sap.xi.repository
Deployed the install version of com.sap.xi.repository.
In order to correct the problems with the incorrect screens etc.. The following steps were carried out:
Undeployed com.sap.xi.repository
Deployed the Support Stack 4 version of XITOOLS (includes com.sap.xi.repository)
Applied Support Stack 5 for the Abap kernel
Applied SAPXIAFC04P_1-20000272 and SAPXITOOL04P_1-20000274 via SDM
This fixed all of the problems with German texts etc.. but now we cannot import RFC / idocs again. In the Java Web Start Log (attached) we still get the error message
mentioned in note 769356. We have deleted the Web Start Cache on the client hosts (several restarts of the machine and deletions of the cache). The BASIS guys are going to undeploy and redeploy the repository again but failing that we are running out of ideas.
Does anyone have any suggestions?
Here is the entry in the log file:
java.lang.AbstractMethodError: com.sap.aii.ibrep.sbeans.upload.UploadServiceRemote_Stub.openSAPSource(Lcom/sap/aii/utilxi/misc/r3Connect/SAPConnectionData;Lcom/sap/aii/utilxi/misc/r3Connect/SAPLoginData;Lcom/sap/aii/ib/bom/gen/VersionContext;)Lcom/sap/aii/ibrep/sbeans/upload/SourceID;at com.sap.aii.ibrep.clsif.upload.RemoteUploadClient$ConnectionImpl.connectBean(RemoteUploadClient.java:107)at com.sap.aii.ibrep.clsif.upload.RemoteUploadClient$ConnectionImpl.<init>(RemoteUploadClient.java:91)at com.sap.aii.ibrep.clsif.upload.RemoteUploadClient.getSAPUploadConnection(RemoteUploadClient.java:66)at com.sap.aii.ibrep.gui.tools.r3import.wizard.SAPLogonPage.connect(SAPLogonPage.java:94)at com.sap.aii.ibrep.gui.tools.r3import.wizard.R3ImportWizard$LoginTask.run(R3ImportWizard.java:456)at com.sap.aii.utilxi.misc.thread.ThreadPool$ThreadPoolThread.run(ThreadPool.java:321)

Dan,
you are almost there!
If you religiously follow note 769356, you should not have this problem.
Just do the following as the note suggests:
- From SDM, undeploy only the com.sap.xi.repository
- Unzip SAPXITOOL04P_1-20000274.SCA.zip
- The file ExchangeRepository.sda will be one of the extracted files
- Only import the ExchangeRepository.sda. Do not import the entire ZIP package.
- Restart the J2EE engine.
- Delete Webstart Cache
- From the XI admin page:
http://XIhost:50000/rep/support/admin/status.html
Re-Initialize the Jars for resigning.
- Wait for 5 minutes for the jar signing to finish. Sometimes, the jar signing gets interrupted, you have to let it finish.
The above steps worked for me.
thanks,
Manish

Import RFC Model

All,
I'm using Sneak preview full java version. When I try to call SAP Function module from webdynpro Java via RFC Model, it's asking me to specify the SAP Server detail logon information.
Can anyone help me what information i should give becos im using Sneak preview Java version...
Thanks..

Hi Bharathi
If u want to import Adaptive RFC Models from ABAP backend u have two ways for importing the model
1) single server : where u need to specify ABAP system creditials such as Application server name,client,system number for ABAP system available in ur Local Area Network
2) Load Balancing : Here DropDown List is automatically populated with list of ABAP servers which are defined in ur SAP LOGON PAD . Actually NWDS picks up names of these servers from saplogon.ini file which stores all ABAP servers defined in ur SAP LOGON PAD
so if u have entry for the required ABAP backend in ur SAP LOGON PAD then u can go for Load Balancing method in which most of the entries will be automatically populated from saplogon.ini file
If u donot have SAP LOGON PAD or saplogon.ini file doesnot have entry for the ABAP server then u should go for single server mode for Importing RFC models
Hope u Got the difference between the two methods now

Import Statement in Java

I have one question about import of packages and classes. If I import java.awt.** why can't all the packages starting with java.awt get imported.For example java.awt.color.* or java.awt.font doesn't get imported. I didn't get why so and if so then why these classes were prefixed with java.awt. Same case happened to me when I imported java.util.* and didn't find java.util.concurrent.locks.Lock get imported. There must be some reason behind this. But I don't know. Can anyone please let me know ?

Import statement in .java files and .jsp files ..correction

Guys I have few mysteries about this import statement.
Please correct me if I am wrong.
1)Suppose if I have a folder c:\SourceFolder it has one.java and two.java files.If I compile one.java then one.class files is created in c:\ClassFolder .Now two.java uses one of the method of one.java,and without using import statement in two.java I am able to compile two.java, and two.class file is created in c:\ClassFolder.I assume that the path of one.class was taken from the CLASSPATH environment variable,hence I there was no need for import statement .........am i right ?
BUT... in My.jsp,which is in C:\JspFolder, if I want to use one.class,then I have to specifically import one.class in My.jsp .That is i have to say
<%@page import="one"%>
in My.jsp.
and since the classpath is C:\ClassFolder ,it finds one.class in the C:\ClassFolder and MyJsp is compiled sucessfully.(Note that My.class is created in a folder different from c:\ClassFolder )
But I am wondering why was there no need for me to import one.class in two.java.
(Note I am using JDeveloper and Apache server)
Please help.

It has to do with packages. Most java classes are in a package, the name of which must conform to its place on the filesystem relative to the classpath. By that I mean that if you have com.mystuff.One.java, it must be in a folder com/mystuff where com is located somewhere in the classpath.
What you've done is a little different. I'm assuming a couple of things:
1. you have no package declaration at the top of one.java or two.java
2. you have the current directory "." in your classpath.
Java has the concept of the "default package", which covers classes without a declared package, and in your case is the current directory.
So when you're in c:\sourcefolder and run the compiler, then "."="c:\sourcefolder", and that directory is part of the default package. No import statements are necessary for classes that are in the same package. This is why two.java can call methods in one.java without an import statement.
When you run your jsp, the "current directory" part of your classpath is not c:\sourcefolder, but some other value (probably the directory you start your jsp engine from) You will have to import all non-java-library classes because the jsp itself becomes a java class, with a package that is determined by the jsp engine.

Problem in mapping xml data with imported RFC parameters

I am currently working on a senario in which a flat file is generated by an RFID server and placed in FTP server.
The flat file is picked up from the FTP server using XI and the contents are mapped to the corresponding imported RFC parameters.
The content of the file which is in text format is successfully converted in XML at the XI side.
File contains records of 2 fields Functional location and RFID equipment number . In the R/3 side these fields
are used as Functional location and equipment number of PM module .
The structure of the FTP message is as follows
<ns:RFID_MSG_TYPE xmlns:ns="urn://sisl:rfiddemo">
<RecordSet>
<Row>
 <FL1>"f1</FL1>
 <FL2>01</FL2>
 <FL3>01</FL3>
 <RFID_NUM>I001"</RFID_NUM>
</Row>
</RecordSet>
</ns:RFID_MSG_TYPE>
After the mapping program which maps the above structure to the imported RFC is executed the following payload document is generated
<ns:ZRFID_EQUIP xmlns:ns="urn:sap-com:document:sap:rfc:functions">
<RECORDS>
<item>
 <FLOC>f1-01-01</FLOC>
 <RFID_NO>I001</RFID_NO>
</item>
</RECORDS>
</ns:ZRFID_EQUIP>
The size of FLOC is 30 of type string and RFID_NO is also a string with size 18.
When the data is brought in R/3 both the fields FLOC and RFID_NO gets mapped in FLOC which is of type char30.

Hi Naveen,
In sxmb_moni the content transmitted to the adapter(RFC)is as follows
<?xml version="1.0" encoding="UTF-8" ?>
- <ns:ZRFID_EQUIP xmlns:ns="urn:sap-com:document:sap:rfc:functions">
- <RECORDS>
- <item>
<FLOC>f1-01-01</FLOC>
<RFID_NO>I006</RFID_NO>
</item>
- <item>
<FLOC>f1-01-02</FLOC>
<RFID_NO>I002</RFID_NO>
</item>
- <item>
<FLOC>f1-01-03</FLOC>
<RFID_NO>I003</RFID_NO>
</item>
- <item>
<FLOC>f1-01-04</FLOC>
<RFID_NO>I004</RFID_NO>
</item>
- <item>
<FLOC>f1-01-05</FLOC>
<RFID_NO>I005</RFID_NO>
</item>
- <item>
<FLOC>f1-01-06</FLOC>
<RFID_NO>I001</RFID_NO>
</item>
</RECORDS>
</ns:ZRFID_EQUIP>
At r/3 side the field floc and rfid_no gets mapped to floc which is of char30
eg floc=f1-01-01I006
 rfid_no=

Importing RFC from R/3 3.1i PI 7.0

Hi,
The scenario is picking a file from third party FTP sever and posting an Idoc into SAP R/3 3.1i using PI 7.0. In between we call an RFC from R/3 3.1i from PI 7.0 for converting values. The problem here is, where we tried to import RFC from R/3 3.1i into PI 7.0, its is not allowing to import.It says unauthorized access, even though i had permissions to do that.
1:) Is this a compatible issue?
2:) Can we import RFC from 3.1i into Pi 7.0? Then why i am not able to?
3:) Is there any other way to use that function module in mapping?

Hello
1:) Is this a compatible issue?
- yes
2:) Can we import RFC from 3.1i into Pi 7.0? Then why i am not able to?
- No, this is not supported. The import of RFCs and IDocs is supported from SAP Release 4.0 and higher.
3:) Is there any other way to use that function module in mapping?
- If the RFC is not too complex, just created the objects in the ESR. Or import from a system which is > 4.0.
Check the KBA #1535964 How to import an IDoc/RFC into the ESR, for further details.

Imported RFC with problem in converting to XML

Hello,
another nice issue:
I have an aRFC with this import parameter from ABAP:
data: p_data type tab512 occurs 0.
Call function.......
Tables
DATA = p_data
This is the XML source from the mapping test in Int.Rep.
<?xml version="1.0" encoding="UTF-8"?>
<ns:Z_BI_SEND_DATA_512 xmlns:ns="urn:sap-com:document:sap:rfc:functions">
<SYSID_HOME>AAA</SYSID_HOME>
<TARGETSYS>BBB</TARGETSYS>
<DATA>
 <item>test1</item>
 <item>test2</item>
 <item>test3</item>
</DATA>
</ns:Z_BI_SEND_DATA_512>
This is the payload from SXMB_MONI:
<?xml version="1.0" encoding="UTF-8" ?>
- <rfc:Z_BI_SEND_DATA_512 xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<SYSID_HOME>AAA</SYSID_HOME>
<TARGETSYS>BBB</TARGETSYS>
- <DATA>
- <item>
<WA>test1</WA>
</item>
- <item>
<WA>test2</WA>
</item>
- <item>
<WA>test3</WA>
</item>
</DATA>
</rfc:Z_BI_SEND_DATA_512>
Looks like there is a difference (imported RFC in mapping does not show the work area WA)(so: mapping requires
<DATA>
 <item>test1</item>
but RFC generates
- <DATA>
- <item>
<WA>test1</WA>
which hinders the mapping from moving the item lines into the destination file because in mapping the WA area cannot be linked as it is not recognized in mapping.
Any ideas are welcome!
Regards
Dirk

Hi everyone
My problem is related to Dirk's one in that I am using an RFC to send XML data from CRM to XI.
I am trying to send the following string:
<TEST>GREG</TEST>
However on XI the payload looks like this:
<xml version="1.0" encoding="UTF-8"?>
<rfc:_-MARS_-CPE_IMPORT_CRM_CATALOG xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<IV_CATALOG><TEST>GREG</TEST></IV_CATALOG></rfc:_-MARS_-CPE_IMPORT_CRM_CATALOG>
As you can see < is converted into <
Where and how do I specify that the content of the parameter must not be interpreted?
Thanks
Greg

Problem importing RFC/IDOC

Hi All,
While importing RFC/IDOC, there are 3 steps
1. Logon
2. Choose Objects
3. Execute imports
After giving the reqd info in logon, I can go to the next step, but here when I click on RFC or IDOC, I am not able to see the RFCs or IDOCS, IR is not responding, the screen goes blank and I have to close the application(IR).
Any help is appreciated.
Thanks,
Jai Shankar

>>wasn't it 3 that felt like 15 ?
No i guess it is a 15 actually.
>>do you have many Zidoc - ZRFC ?
Yes. This is a IDES system I am connectin to. So lot of them.
Thanks,

Hi Sudheer,
Kindly check the user having all authorizations which you are try to importing the RFC's from ECQ to XIQ, check with your basis team and try to provide the required authorizations for that particular user.
Then you can able to import RFC's and do the design by activating the objects.

RFC - XI - Java Proxy HTTP_RESP_STATUS_CODE_NOT_OK

Hi all,
I need to work on RFC->XI-> Java proxy.
While excuting, i am getting an error :
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="INTERNAL">HTTP_RESP_STATUS_CODE_NOT_OK</SAP:Code>
<SAP:P1>400</SAP:P1>
<SAP:P2>Bad Request</SAP:P2>
Can any body please guide?
Regards,
Kulwant

Hi Kulwanth,
Plz do check the mentioned possibilities for your error one by one:
1.Did you maintain Client, userid, password, and lang information in SICF transaction -> sap/xi/engine? Double click on service and check whether you have entered correct information.
2.Then you might check the roles of the XIISUSER in SU01. In some case there are some double roles, i.e., two times the role SAP_XI_IS_SERV_USER assigned. One might have the date of the last update, the other one might have apparently the older version. Delete the older roles manually and the error should disappear.
3.to send messages to xi you need a service id / pwd which is specific to your landscape usually its xiappluser. Contact your basis group for password.
4.
Activated all services on the r3 system.
Create HTTP connection to XI from r3
sm59-> http connetons to r3
let us say you have created a HTTP connection in the integrationserver_XI, make sure in its settings the prefix path is set to /sap/xi/engine?type=entry. Also check its log on credentials, you can use xiappluser.
IN Integration builder, receiver communication channel make sure you have entered proper
host service number
path = /sap/xi/enigne?type = receiver.
5. It might also be that you have authorization problems with your XISUPER. In the visual administrator and in ABAP SU01, make your XISUPER has all the necessary(SAP_SLD* and SAP_XI*) roles assigned to it. If not, try to assign these and see if this can be of any help.
6. can you also try the following;
Visual Admin -> start the service,
"com.sap.aii.af.ms.app".
Please go through the followings links also :

** Not able to Import RFC - RFC to RFC scenario

Hi Friends,
I have created one technical system in SLD which is already configured with XI system. I have created one business system for this technical system.
I have created one SWCV and one namespace. Now, I have tried to import one RFC under 'Imported Objects' in this SWCV by giving proper logon details in the SWCV and Import Objects dialog box. But, the system throws the following error.
Unable to establish connection to R/3 system computer8 (system=00, client=800) Troubleshooting tips:
Is the target system online?
Check the connection data (note that server names and groups are case-sensitive)
Tips for administrators (see the configuration guide for more details):
Does the user have the required authorizations in the target system?
Is the target system configured correctly in "etc/services"?
I have checked the login password, host name, etc. everything is correct.
What could be the problem?
Friends, Kindly help me to solve this issue.
Thanking you.
Kind Regards,
Jegatheeswaran P.

Hi jega,
go to R/3 system and check your Function module weather it is activate or not.
save and activate it.
Also check the connection between XI and R/3.
