Dynamic FileName and Directory - UDF

My scenario is to get Target Directory Name based on part of Filename. How can I do that using UDF. I will select adapter specific parametrs and like to change using UDF. TO achive this I will create a dummy field names in the target structure. Can someone let give me UDF code?.
For Example: Source FileName : SD00123456Prod.csv
Target Directory Should be /Sales/
Target File: Prod.csv
Thanks for any help.

I changed function this time. I took exact coy of Michals Blog.
Function:
public String SourceFileName(Container container){
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;
Now the error when activate message mapping:
Activation of the change list canceled Check result for Message Mapping Source_2_Target | http://test.com: Starting compilation Source code has syntax error: /usr/sap/DPI/DVEBMGS01/j2ee/cluster/server0/./temp/classpath_resolver/Map36d73f104e5e11db977f001125a56eca/source/com/sap/xi/tf/_Source_2_Target_.java:55: cannot resolve symbol symbol : variable conf location: class com.sap.xi.tf._Source_2_Target_ String ourSourceFileName = conf.get(key); ^ 1 error

File Scenario with Dynamice Filename and Directory

Hi All,
we have a requirement that PI has to pickup the file from 2 FTP Server.
First PI has to pickup an XML file from Server1 , this XML file has a details about the Filename and Directory of the second FTP server., then PI should login to the server2 and pickup the file form the directory.
Regards,
Mani

Hi Mani,
Can you try below approach ,
Read file 1 from Server 1 using sender file Communication channel and read 2nd filename and directory details and pass these values to UDF/Java mapping to log in to server 2 and retrieve the data/file2 ?
Thanks

Dynamic File and Directory Name without Mapping

Hello Experts,
We have following requirement:
1) Files will be picked from R/3 AL11 directory and would be placed in corresponding folder in target system.
2) On source side ,there would be only one folder for all types of files(around 20),but on target side,there would be one folder for each kind of file(20 folders)
3) File name should be same on the target side but target directory should be selected based on file name.
I have gone through a number of posts related to similar requirements and hence,sorry for a new post but I am not yet able to find a solution to this.
I could understand,this can be achieved using DynamicConfiguration UDF .
But I have no possibility to have mapping in my scenario.It would just be a pass through scenario.
Can anyone please suggest a solution to this?
Thanks.

Shweta

Hello,
Thanks a lot for suggesting solution to this problem.
I could achieve this using following Java mapping:
import com.sap.aii.mapping.api.*;
import java.io.*;
import java.text.*;
import java.util.*;
public class GetDynamicConfiguration implements StreamTransformation {
    private Map param;
    public void setParameter(Map map1) {
        this.param = map1;
    public void execute(InputStream inputstream, OutputStream outputstream) throws StreamTransformationException {
        try {
               AbstractTrace trace = null;
            // a) Set ouput File name
            String directory=null;
               trace = (AbstractTrace)param.get(StreamTransformationConstants.MAPPING_TRACE );
            param.put(DynamicConfigurationKey.create("http://sap.com/xi/XI/Dynamic", StreamTransformationConstants.DYNAMIC_CONFIGURATION), "");
            DynamicConfiguration conf = (DynamicConfiguration) param.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
            DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
               DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "Directory");
            String filename =conf.get(key);
            conf.put(key, filename);
               trace.addInfo("File name is "+filename);
            if(filename.equals("in.txt"))
            directory = "/home/ftpxi/in";
               if(filename.equals("test.txt"))
               directory = "/home/ftpxi/in/test";
               if(filename.equals("shweta27.txt"))
               directory = "/home/ftpxi/in/test";
               trace.addInfo("Directory name is "+directory);
               conf.put(key1, directory);
            // b) Just copy input file to output file
            byte[] b = new byte[inputstream.available()];
            inputstream.read(b);
            outputstream.write(b);
        } catch (Exception exception) {
            exception.printStackTrace();

Get filename and directory name during runtime

Hi guys,
I am developing a file to file interface without content conversion, just a simple file transfer from one ftp server to another. I have to read the same filename (invent.txt) from multiple folders (mstransfer/M01/IN1, mstransfer/M02/IN1, mstransfer/M03/IN1....) that represent different stores and transfer it as it is with the same name to exactly the same directory name in the target ftp location.
My problem is found inside a dummy mapping that I have created in order to specify the target directory and the name of the file. I am doing the following:
A) A Java UDF to specify the filename
trace = container.getTrace();
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String filename = conf.get(key);
trace.addWarning("filename = "+filename);
conf.put(key, filename);
return "";
//return filename;
B) A Java UDF to specify the directory name
//write your code here
trace = container.getTrace();
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","Directory");
String directory = conf.get(key);
trace.addWarning("directory before = "+directory);
directory = "/usr/sap/trans"+directory;
trace.addWarning("directory after = "+directory);
conf.put(key, directory);
return "";
//return "/usr/sap/trans"+directory;
In receiver file adapter I do not specify neither a filename nor a target directory.
When I am testing it, I always get a mapping runtime error.
Any ideas?
--Evaggelos

Guys,
First of all, I am doing an end to end testing, i.e. I let the FTP adapter pick the file up and another FTP adapter delivers the file to target folder. I am definitely not testing the mapping in mapping editor.
I get the error in Request message mapping (pipeline step, which I can see in SXMB_MONI transaction) which is a dummy mapping between two message types that I have created and are based on two data types with two fields each.
The UDF's that I have created go in-between the source and target fileds of the message types/data types.
The error that I see in the trace section of the XML message in SXMB_MONI is the following:
"<Trace level="1" type="T">RuntimeException during appliction Java mapping com/sap/xi/tf/_MM_G_SRS_FileTransfer_MNS_</Trace>
<Trace level="1" type="T">java.lang.NullPointerException at com.sap.aii.mappingtool.tf3.AMappingProgram.exceptionCaught$(AMappingProgram.java:59) at com.sap.aii.mappingtool.tf3.Transformer.checkParserException(Transformer.java:182) at com.sap.aii.mappingtool.tf3.Transformer.start(Transformer.java:149) at com.sap.aii.mappingtool.tf3.AMappingProgram.execute(AMappingProgram.java:102) at com.sap.aii.ibrun.server.mapping.JavaMapping.executeStep(JavaMapping.java:64) at com.sap.aii.ibrun.server.mapping.Mapping.execute(Mapping.java:91) at com.sap.aii.ibrun.server.mapping.MappingHandler.run(MappingHandler.java:90) at com.sap.aii.ibrun.sbeans.mapping.MappingRequestHandler.handleMappingRequest(MappingRequestHandler.java:95) at"
I have included some trace.addWarning() lines in Java code to help me debug my code, but I cannot see them anywhere inside the trace to be getting executed.
I will try Bhavesh's idea and I will write the code in the Java Section of my message mapping ( either Intialization or Destrcution ) section.

Variable filename and folder in receiver cc

Dear experts,
On PI, I need to create a (text-) file with a variable name and folder. The scenario is as follows:
idoc-> PI -> txt file
In my incoming Idoc I get the following data:
- directory where the txt file should be saved;
- name that the txt file should get.
How can I realise this in PI? Using variable substitution? As I never done this before, I have a hard time getting this to work...
Please help.
Thanks in advance
William

Hi,
Use Dynamic Configuration:
Input will be 2 variables var1, var2.
String Name1 = var1;
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
conf.put(key1, Name1);
String Name2 = var2;
DynamicConfigurationKey key2 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "Directory");
conf.put(key2, Name2);
return "";
Maping:
Var1---
UDF----TargetMessageNode.
Var2---
Under ID: Enable ASMA in file receiver adapter and chk FileName and Directory.
and put * under File name and / underTarget Directory(File receiver).
NOTE: U can alter this UDF according to ur req.
Thanks
Amit

Dynamic FileName based on environment

Hi expert,
I have a proxy to file scenario in which I create dynamic FileName using an UDF. I'm using UDF because filename must contains date with a particular date format (yyDHHmm).
My need is to generate file name prefix based on environment, for example:
In DEV environment FileName must start with T
In QTY FileName must start with Q
In Prod FileName must start with G.
Is possible to catch the environment name in UDF (I think from DynamicConfiguration)?
Which values I have to test in the IF statement?
thanks,
Fabio

Hi Fabio,
Is possible using:
String EnvironmentName = (String) System.getProperty("SAPSYSTEMNAME");
Then, you can use the IF statement and a Concatenate statement:
String output = null;
if (EnvironmentName == 'DEV') {
output = "D" + Filename;
} else if (EnvironmentName == 'QAS') {
output = "Q" + Filename;
} else if (EnvironmentName == 'PRD') {
output = "P" + Filename;

File and directory names with Danish characters

I have installed the Novell Client v2.0 for Linux on my Open Suse 10.3. The Client is connecting to my Netware servers (6.0 & 6.5) without any problems...
There is one problem... Filenames and directory names with the Danish , & (ae, oe & aa), e.g the filename bger.doc (bger = books) is shown as b. and when clicking the file the file disappears from the file list. It seems to be the same problem with the German (umlaub).
What to do?

As far as I know, the Novell Client for Linux expects that file and
directory names use the UTF-8 encoding and does not support a traditional
8-bit encoding like ISO 8859-1. Try changing the encoding of file and
directory names to UTF-8 as described in
SDB:Converting Files or File Names to UTF-8 Encoding - openSUSE

Seems a good hint. When I create a folder or file from within SUSE using an "Umlaut" everything is OK and NCL 2.0 displays them correctly as they are UTF-8 formatted.
The proposed tool is no solution: one cannot convert folders or files that one cannot see (does it work for folders at all?). Maybe a windows tool would work because one could search for all files or folders with "Umlaute" and convert them. Other options?

Dynamic Filename in BPM process (SOAP with attachm. and PayloadSwapBean)

Hello together
I have the following BPM process:
1. IDoc=>WebServiceRequest
2. WebServiceResponse (payload) => IDoc
3. WebServiceResponse (attachment) => File
XI receivs an IDoc an map it to an WebService. The Webservice is called by XI and we receive the WebServiceResponse including a PDF attachment.
The challenge is to store the PDF attachment with a dynamic filename from the payload of WebServiceResponse.
We use the PayloadSwapBean to change the payload to the PDF attachment. But then we are not able to access the required information on the original WebService-XML-Response via variable substitution.
Is there a solution in the standard or have we to use a custom adapter module?
Thx
manuku

Hi Jayasimha,
We can do this by "Adapter Specific Message Properties" of ur comunication channels.
1.If u want to keep the output filename same as input filename, no need to use the UDF. only the 'adapter specific parameters' in both sender n receiver file adapter will do that.
In case if u want to get the filename inside our mapping we have to create a user defined function
which will return the filename and map it to one of our XML tags. 2nd point gives solution 4 that:
2. If u want to generate an output file taking some input from the payload,then u hav to use the UDF.There u hav to populate the name.
Pretty much.... if you set an attribute from the sender side, for example, you can use a UDF and access the particular attribute sent and use it in the mapping. In another example, where no attributes are sent from the sender, you can still actually set a particular attribute, say a filename derived from the payload, using a UDF, and enable the receiver attribute to use it. That's where the UDFs come in - either to get or set particular adapter specific message attributes.
This will be a very helpful blog which solves ur query:

Dynamic File Name and Directory File Sender Adapter

Hello gurus,
I have a question: Is there any way to make the File Name, and Directory Dynamic of a File Sender Communication Channel ?
For example, taking it as a parameter from a Web Service Request.. (I mean, the only way with this would be a ccBPM). I don't exactly know if there is a way, I just thought about this.
Please tell me if someone could make Dynamic these 2 parameters while picking a file.
Regards,
Juan

oops,thought i was replying to the PgP question:)
I think you should be able to achieve this via adapter module but i m not really sure how exactly it will be done .
Thanks

ABAP mapping split messages and dynamic filename

Hello,
i have set up a IDOC to file scenario where the IDOC is split into several files, which works fine. In addition to this it is required to set a dynamic filename out of the ABAP mapping for each file. If only one file is created this works already as well but how do you set the dynamic configuration when the messages are split?
Regards,
Andreas
Edited by: Andreas on Feb 26, 2009 9:09 AM

you cannot do dynamic configuration for message splits. The below is from SAP help.
Adapter-Specific Attributes and Multi-Mappings
In multi-mappings, there are multiple message headers with adapter-specific attributes. The mapping API can only access one message header. This has the following consequences depending on whether there are multiple source or target messages:
u25CF     1:n Transformation
If there are multiple target messages, the header for the adapter-specific attributes is copied for each message. This means that you can only create one header for all adapter-specific attributes, and not individual headers.
u25CF     n:1 Transformation
This variant is only possible for multi-mappings in integration processes. If there is more than one source message, read-access to the adapter-specific attributes of the various message headers is not possible at runtime.
u25CF     m:n Transformation
All afore-mentioned restrictions apply here. Developers can at most write the same adapter-specific attributes for all target messages to the header, without read-access to the attributes of the source messages. m:n transformations are only supported within integration processes.
What i will suggest is to use BPM to have the message split i.e 1:N mapping and then after that have another mapping 1-1 to have the dynamic configuration

How to pass dynamic filename to Receiver JMS channel

Hi experts,
I want to pass the dynamic filename to receiver JMS message Properties.
for example
I am passing directory name via adapter module AF_Modules/DynamicConfigurationBean with key and value combination like below. How to pass dynamic filename value to a dynamic property ( say DCJMSMessageProperty1)
eg.
key.0 - >insert http://sap.com/xi/XI/System/JMS DCJMSMessageProperty0
value.0 - > testdirectory ( which is static value)
Note: Im have not created any ESR object . i just have to bypass the file to a jms queue. I have used AAE integrated configuration scenario ( file to jms )

Already given link for the dynamic configuration code snippet in the earlier reply... Below is the code snippet
Note: Use Adapter Specific Message Attributes for the target Communication Channel(CC).Check the indicator for filename in the advanced tab of CC
//UDF code
String filename="";
String NameSpace = "http:/"+"/sap.com/xi/XI/System/JMS";
try{
      DynamicConfiguration conf = (DynamicConfiguration) param.get(
        StreamTransformationConstants.DYNAMIC_CONFIGURATION);
      DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File",   "FileName");
       // read filename value
       filename = conf.get(key);
      // So far we extracted filename value .. now do your logic something like this...
      DynamicConfigurationKey key2 = DynamicConfigurationKey.create(NameSpace,"yourjmsvalue goes here");
       conf.put(key2,filename);
     } catch(Exception e){

Same Dynamic Filename used multiple times

Hi all,
In PI we would like to use the same dynamically created filename for multiple outputs of the same file in different locations.
Is it possible to create the filename and save it in a Java container (for instance) that can be accessed by other mapping programs?
Many thanks,
Aldo

Just to correct you here... Your requirement is to reuse the file name value in different mappings and NOT to reuse the udf code.
The above blogs say's how to reuse the udf code in different mappings... So make sure what exactly you are looking for...
UDF can only store the value at run time for a particular mapping... once execution is over the value will be lost.
So as suggested by Sunil, you can store the file name into some table and then use the RFCLookup get it into your another mappings...
