UDF or Adapter?

XI Geeks,
we have a scenario IDOC to file.
can create file at OS level using UDF with no Receiver & Sender agreements.
when UDF can serve the purpose of an adapter what else we need,just need configuration part in identifying the right UDF thorugh reciever and interface determination.
my question is in what way UDF can command over Adapter performance factor for the above scenario.
Thanks & Regards,
Rama Krishna

HI Rama,
Please can you be more clarified about usag of your UDFs to download or upload the file.
Adapters are used to communicate with FTP server. PRobably with UDFs you may have restricted only to NFS protocol.
You have not required sender and receiver agreement coz, you have downloaded or uploaded the fiel on XI server only and its in XML format.
But for any conversions youhave to go for File adapter.
Even from the security perceptive (FTPS/SFTP) you have to go for adapters.
Thanks

Java Mapping (not UDF) and Adapter-Specific Message Attributes

Hello everybody,
is it possible to create an Adapter-Specific Message Attributes in a java Mapping?
I found in the SAP Help that the API com.sap.aii.mapping.api.DynamicConfiguration allows only to read, change or delete the attributes.
best regards.

File to File with no mapping (different filename)

I have a requirement to change the name of the filename in a file-to-file scenario. The prefix of the file will stay the same, but the target file needs to have a date format replace main part of the file. The date format is also specific YYYYMM. Below are the two examples of the source and target filenames. We are not doing a message mapping with this scenario.
Source: CA_MONTHLY_REPORT.txt Target: CA_200901_01.txt
Source: US_MONTHLY_REPORT.txt Target: US_200901_01.txt
The date needs to be calculated off a date function for current month and year.
Is this possible to do?
Thanks

With mapping (UDF) it is easy. But I guess you're not allowed to use mapping, you would need to introduce adapter module.
I think with the standard configuration, you can not archive it. You have to use either UDF or adapter module.

Missing Message Attributes: URL/HTTP Destination

Hello,
following scenario:
There is a sync. interface between SAP PI ante the Paypal API within the HTTP adapter calling a dynamic URL.
The dynamic URL is created as mentioned in this blog: http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/7264. [original link is broken]
Also the HTTP adapter is configured as described (Adapter Specific Message Attributes and URL are flagged).
Following error occours when testing the call:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
<SAP:Category>XIAdapter</SAP:Category>
<SAP:Code area="PLAINHTTP_ADAPTER">ATTRIBUTE_MISSING_URL</SAP:Code>
<SAP:P1 />
<SAP:P2 />

<SAP:P4 />
<SAP:AdditionalText />
<SAP:Stack>Dynamic Header - Missing Message Attributes: URL/HTTP Destination</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Is there sth. special I have to consider in the HTTP Adapter?
Thanks in advance,
André

Hi Michal,
I´m passing the URL to the attribut "TargetURL" by using a UDF in my mapping.
In the adapter I have flagged "URL".
So the value of TargetURL set in mapping shoul be used as destination in the adapter.
Please have a look onto my UDF used in MM:
http://img408.imageshack.us/i/udf.jpg/
Adapter settings:
http://img691.imageshack.us/i/adaptersetting1.jpg/
http://img339.imageshack.us/i/adaptersetting2.jpg/
How can I check that the TargetURL is successfully set as a dynamic parameter?
Thanks,
André

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

Serialize IDOCs PI to SAP Backend

HI,
I need to serialize IDocs thats PI send to a sap backend system.
rigth now we have one CC with max connection = 1 but it is not enough.
but something is not clear at all for me.
I need to send IDocs with QoS EOIO so, i asume that checking the parameter "Queue Processing" in the IDoc Receiver Channel the IDocs will sen them to SAP in EOIO, but that means --> One queue will be defined(in backend) for each IDoc that use this Channel?.
If i set this functionality could i increase the parameter max connection to 10( for example) and the channel should know which queue was defined for each IDoc in the backend or it is not possible and I am thinking crazy things.
Is it possible also to configure the transaction IDXQUEUE in SAP Backend?
Best Regards.

Searching for othar alternatives y found that is possible to change the QoS or the Queue id values in a Messager Mapping.
Change Queue name in Message mapping
http://help.sap.com/saphelp_nw04/helpdata/en/6e/ff0bf75772457b863ef5d99bc92404/frameset.htm
but as i can see, there is not possible to access the variables QUEUE_ID and QUALITY_OF_SERVICE since those are ReliableMessaging's variables(help.sap link above)
so i can access all Main's variables like SENDER_SERVICE, MESSAGE_ID, etc etc)
How can i get access to this ReliableMessaging's variables from UDF or Adapter Module?
In the thread above someone mentions that was not able to modify those values in a UDF but in a Adapter Module (i asume using the same code below) what could be the difference accessing frmo UDF o Adapter Module?
UDF Code
java.util.Map map;
DynamicConfiguration conf = (DynamicConfiguration)container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey qos = DynamicConfigurationKey.create("http://sap.com/xi/XI/System","QUALITY_OF_SERVICE");
conf.put(qos,"EOIO");
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System","QUEUE_ID");
conf.put(key,queueName);
return "";

Tools to Learn Java!

Hi,
Can anybody mention some freeware tools which we can download to learn core Java for UDF and adapter modules.

Hi,
First you download eclipse from http://www.eclipse.org/ or NWDS from http://www.sdn.sap.com/irj/scn/downloads?rid=/library/uuid/d04ac7ef-0fe7-2c10-efb1-d27b38d730b3.
You can refer any e-book or e-material to start from the begining if you are very new to java.
For SAP related APIs in java, you can refer - http://help.sap.com/javadocs/pi/SP3/xpi/index.html. Here you will find all APIs which are used for any Java Development in PI.

Error in while calling a Soap Adapter using the UDF

hi,
i am trying to make a call to Soap Adapter using a UDF.
The code of the UDF is as follows :
InputStream isPayloadStream = null;
AbstractTrace trace= container.getTrace();
String sService="Business Component";
String sChannelName="Soap Channel(Sender)";
SystemAccessor accessor=null;
trace.addInfo("entered UDF");
StringBuffer sb = new StringBuffer(" ");
trace.addInfo("creating the reference file");
sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");
sb.append("<ns0:MT_123082_UDF xmlns:ns0=\"http//infosys.com/pi/projects/png/n1\">\n");
sb.append("<INTERCHANGECONTRLNOS>" + var1 + "</INTERCHANGECONTRLNOS>");
sb.append("<PGPARTNERID>"var2"</PGPARTNERID>""\n""</ns0:MT_123082_UDF>");
trace.addInfo("trigerring the SOAP channel ");
try{
Channel channel = LookupService.getChannel(sService,sChannelName);
accessor = LookupService.getSystemAccessor(channel);
isPayloadStream = new ByteArrayInputStream((sb.toString()).getBytes());
trace.addInfo("creating the xml payload ");
XmlPayload payload = LookupService.getXmlPayload(isPayloadStream);
Payload result=accessor.call(payload);
catch (Exception e){
trace.addInfo(e.getMessage());
finally{
if ( accessor !=null) {
accessor.close();
return " ";
The above code is throwing an error while end to end testing.
the scenario is such,while graphical mapping a UDF will be used, which will create an Xml payload, and send this payload to another SOAP to file scenario.
The error in the sxmb_moni is: "Error when calling an adapter by using the communication channel CC_123085_UDF_SOAP_OUT (Party: , Service: BC_123082_REMADV_D96A, Object ID: fa9c6ee15efc30c68ec34b08034d87d1) XI AF API call failed.

UDF to get the filename for File Sender Adapter

Hi,
I had an requirement to get the the Filename and map to the target payload.
I had configured the File Sender Adapter settings in the ID
This is the following UDF i got from SDN.
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
But when iam using this UDF iam getting an error
RuntimeException in Message-Mapping transformation: Exception:[java.lang.NullPointerException] in class com.sap.xi.tf._MM_ORDER_CRS_OB_SAP_PROXY_IB_ method Filename$[com.sap.aii.mappingtool.tf3.rt.Context@54e154e1]
Please help me in correcting the error.
Thanks
Srinivas

Hi Jayson,
actually, in the interface mapping, it doesn't give exception.
The DynamicConfiguration is a constant retrieved from the container object, so it will never be returned as null (given that the container object was instantiated).
Just the retrieved value will be null (since it was not previously set), but no exception occurs.
In the message mapping, the container object is never instantiated, and that's the reason for the NullPointerException.

Henrique.

Is it possible to call mail adapter in a UDF

Hi,
In my mapping if I find that, a field length is more than 50 I need to mail this field in the body of a mail. Can I call the receiver mail adapter in a UDF similar to RFC/JDBC adapter?
Thanks.

Is your scenario contains mapping apart from this?
If not then you can use mailadapter message type provided by SAP.
i dont think you have mapping other than as you want to pass this directly to content right?
Its possible to access body in UDF.

XI Alerts from UDF using file adapter.

I need to send alerts from XI message mapping. I have the file ---> file scenario but don't want he stop the process if any failures in the mapping. If I find any failures, I need to catch the those failures and send as alerts/email report. As per the link /people/bhavesh.kantilal/blog/2006/07/25/triggering-xi-alerts-from-a-user-defined-function, I am not sure whether I can use LookupService for file adapter or not. Can anyone give me some idea on how to send the alerts from UDF using he file adapter ?

Try this...
public String Mail_Test(String input,Container container){
      // Recipient's email ID needs to be mentioned.
      String to = "<Recipient mail ID>";
        // Sender's email ID needs to be mentioned
      String from = "<Sender mail ID>";
       // Assuming you are sending email from localhost
       String host = "<Hostname of the SMTP server>";
       // Get system properties
       Properties properties = System.getProperties();
      // Setup mail server
      properties.setProperty("mail.smtp.host", host);
      // Get the default Session object.
      Session session = Session.getDefaultInstance(properties);
       try{
             // Create a default MimeMessage object.
            MimeMessage message = new MimeMessage(session);
             // Set From: header field of the header.
             message.setFrom(new InternetAddress(from));
             // Set To: header field of the header.
             message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
             // Set Subject: header field
             message.setSubject("Check the problem dude...");
             // Now set the actual message
             message.setText("You did blunder correct that...");
             // Send message
             Transport.send(message);
             System.out.println("Sent message successfully....");

FileName in Sender File Adapter Module

Hi Folks,
In my sender file adapter have written a module to read the picked file name. The protocol used is NFS.
Notice that the file name read in the module has the absolute path, including the directory path. E.g The file name xyz has to be picked from source directory
XIServer\Outbound. In the module when I retrieve the file name, it comes up as
XIServer\Outbound\xyz. Is this expected behaviour?
I was expecting just the file name<xyz> to be retrieved.
Thanks,
Anand

HI,
Create an UDF and write this code.
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key =
DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
in Adapter u will have Adapter specific parameters check the file name check box.
Using this UDF u will get the file name at target side.
Regards,
Phani.
