Handling of empty file

Hi
my Scenario is Proxy to .CSV ,
when there is data proxy is trggering and genarating the .csv file this is working fine. but when i trigger proxy without data it should create a empty file, but this empty file creating with special charecter.
FCC parameter i have used are
Record.fieldSeparator ,
Record.endSeparator <nl>
I would appreciate your timely help.
Regards
Chandra

Hi Chandra,
Instead of using File Content Conversion to convert the file structure, try using the standard module StrictXML2PlainBean instead. The problem is File Content Conversion doesn't identify an empty payload, even if you don't pass anything from the proxy. It doesn't return an empty message to the file adapter.
StrictXML2PlainBean or MessageTransformBean will do the trick for you.
Don't forget to set the empty message handling to Write Empty File.

Problem with „Empty-File Handling" in PI 7.11

Hi,
Iu2019m working in PI 7.11 with file adapter, Sender CC, option: Empty-File Handling: Process Empty Files.
What I want to do is giving target file the system-date, if the source file is empty.
But I always get a mapping error in RTWB: Premature end of file.
It seems that the payload is empty.
Any idea?
Thanks a lot in advance!

What I want to do is giving target file the system-date, if the source file is empty.
The error you are getting makes sense. You should do a check in the mapping, if the payload is empty then use brute force to pass the system date.

Empty File handling and raise alert.

Hi,
We have requirement where we are doing file pass through. But client wants PI to raise alert when it receives 0 byte file.
How can we achieve this using File/FTP/SFTP adapter when we are not reading the actual payload and doing only pass thru?
Thanks,
Vertika

Hi Vertika,
AFAIK - there is no standard way for pass through interface to raise alert (for empty file). so you need to develop adapter module to raise the alert for empty file.
Please refer the help page
Configuring the Sender File Adapter - Advanced Adapter Engine - SAP Library
Under Handling of Empty Files, specify how empty files (length 0 bytes) are to be handled:
Do Not Create Message No XI messages are created from empty files.The files are processed according to the selected processing mode.For example, if the processing mode is Delete, empty files are deleted in the source directory.

Skip Empty Files No XI messages are created from empty files.Empty files are skipped and remain in the source directory.

How to Process an Empty File and deliver to the receiver channel

Hello Gurus,
We had a requirements to process an empty file and send it to the receiver channel . We had successfully configured and polling an empty file, but the message output of the empty file was never sent to the receiver channel. Is there any solution to process an empty file and move it to the receiver directory.
XI 7.0 with latest sp
Thanks so much in advanced,
dn

Thanks guys for a quick response!
As mentioned above, we had already configured to handling "Process empty files" and were able to have the files polling successfully. The problem that we are facing is that, the output file were never created or delivered to the receiver directory. We want all files to process and deliver to the recipients even though it is an empty file.
Thanks,
David

Create a message with empty file in Service pack 9

Hello.
I have the Service pack 9, and when PI read an emtpy file delete it inmediately.
Is there any way to create the message with an empty file? How?

Look into empty file handling in the file adapter. Below is from the sap help documentation for the file adapter.

Receiver file adapter creates empty files, Empty-Message Handling SP19

Hello,
We have just upgraded the system to SP19.
One of the new features is that it should be possible to determine how XI messages with an empty main payload are to be handled in the receiver file adapter.
If the parameter Empty-Message Handling is set to 'Ignore' no file should be created if the main payload is empty. In our case an empty file (size 0 kb) is still created even though the main payload is empty and the flag is set to 'Ignore'.
Has anybody experienced the same problem?
// Best regards Hans

This should work:
Use your own adapter module that parses incoming message and checks if it has any record sets in the document. If it does not have any record sets, then set the message to empty and then give this modified message to File receiver.
For example, see the example code below:
Module imports..
Audit log import..
DOM imports/SAX imports..
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          try {
               // get the XI message from the environment
               Message msg = (Message) inputModuleData.getPrincipalData();
               AuditMessageKey amk = new AuditMessageKey(msg.getMessageId(),AuditDirection.INBOUND);
               Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"RemoveRootTag: Module called");
               XMLPayload payLoad = msg.getDocument();
               Document doc = parseXmlFile(payLoad.getInputStream());
               if(doc != null){
                    if(!doc.getDocumentElement().hasChildNodes()){
                         Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Document is empty!!");
                         payLoad.setContent("".getBytes());
                         msg.setDocument(payLoad);
               // provide the XI message for returning
               inputModuleData.setPrincipalData(msg);
               } catch (Exception e) {
               // raise exception, when an error occurred
               ModuleException me = new ModuleException(e);
               throw me;
               // return XI message
          return inputModuleData;
     private Document parseXmlFile(InputStream xmlpayload) {
          try {
               DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
               factory.setValidating(false);
               //        Create the builder and parse the file
               Document doc = factory.newDocumentBuilder().parse(xmlpayload);
               return doc;
          } catch (SAXException e) {
          } catch (ParserConfigurationException e) {
          } catch(IOException e){
          return null;

Empty File Handling in xLink adapter

Helloo Experts
I am doing a scenario, which creates an empty file(when some mapping condition doesnt satisfy).
I dont want to write this empty file in the target directory.
This can be handled if a file adapter is used, but I am using a SOAP AXIS adapter, so I dont know how to handle this here.
I alaso tried using the StrictXml2PlainBean to avoid the creation, it creates 0 documents and a 0kb empty file.
Can anyone please let me know how this can be solved????
Also if some one has done this empty file handling in J2SE file adapter...can you tell how it was done.
Thanks a lot!!!!!!
Regards
Shobha

Hi Gabriel,
You can write a simple script to copy a file from source folder to target in case the fiel size is ZERO bytes. The script will not copy the file if the filesize is more than zero bytes, This will be processed normally by PI server. You can call the script from sender communication channel parameter : "RUN OS command before message processing". Could you please specify the Operating System (OS) you are using in your PI server.
