Empty file handling

Hi All,
I have a scenario, in which there is a possiblity of getting source file to be empty (0 bytes), In this case I need to trigger an email to the user reg the same. Please provide inputs.
Regards,
Nithiyanandam

Hi,
Maybe you can try out these scenario..
In the sender file channel, keep option as process Empty files and in the sender ASMA properties, select options file name and source file size.
Then in your message map, from a UDF, if the file size in ASMA is zero, you can trigger an email to the intended recipient. Search in SDN, you will get the code for triggering email from a UDF.
Another option would be to go for a conditional receiver determination. There the condition would be the file size of the source file.
In the receiver determination, select condition --> Context Object --> SourceFileSize under file namespace.. If this is 0, select a mail recipient as the receiver and send mail using mail adapter.
If file size is not 0, select your original receiver.

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 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.

Empty File Handling : Do Not Create Message

Hi,
I have set this option in Sender CC - file.
Parameters --> Processing.
I dont want to pass file to reciever , when file is empty.
Will the above option "Do Not Create Message" do the trick.
OR do i need to choose something else??
-santosh.

Santosh,
Yes. The trick will work for empty file handling.
When your incoming file is empty then will be no xml message posted to IE and hence receiver will not get any message.
FYI: Also you can use skip empty files which will do the same but here the files will remain in your source directory.

Empty File Handling in SAP XI------Urgent

Hi Frnds,
1) I have one doubt XI will support Empty file processing. Suppose in my scenario
In sender side i am having Empty file i want to process this file , what are necessary steps i need to take.
2) In my scenario XI will support only 10mb file processing at a time, But in sender side i am having 20 mb file. How to transfer the file without splitting.

hi raja
Regarding empty file processing
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.
○       Process Empty Files
XI messages are created with an empty main payload.
The files are processed according to the selected processing mode.
○       Skip Empty Files
No XI messages are created from empty files.
Empty files are skipped and remain in the source directory.

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.
Process Empty Files XI messages are created with an empty main payload.The files are processed according to the selected processing mode.
Skip Empty Files No XI messages are created from empty files.Empty files are skipped and remain in the source directory.

Empty file handling in Receiver File adapter (FCC - Premature end of file)

Hi
My interface is Flat file to Flat File interface with file content conversion which is working fine in SAP PI 7.1 EHP1.
If I want to process the empty file from sender system, PI should place the same empty file in the receiver FTP Location as per my requirement.
I am facing the below error message when PI tries to place the empty file.
Message processing failed. Cause: org.xml.sax.SAXParseException: Premature end of file.
But if I am not using FCC, I am able to get the empty file at the receiver end.
Please suggest on this, If I am using FCC in the receiver side.
Thanks

How to handle empty file using sftp adapter

Hi,
Please explain me how to handle empty files in sftp adapter.
Thanks,
Enivass

Hi Enivaas,
I don't have the seeburger sftp adapter at hand at the moment, but asfar as I remember, this does not specifically have an empty-file handling option like the standard ftp adapter.
So to stop emtyp files from being written, guess would need to handle this at the mapping level. For example, check for target creation criteria in the header node in mapping. If the creation criteria is not met, you can throw an error in mapping.
You may also incorporate this condition in your Receiver determination. In this case, if the condition is not satisfied, no receiver is determined in PI.

Empty file receiver - file adapter

Hello,
Scenario: File->XI->File.
In my scenerio, I am using Java mapping to name the target filename and creating text file that is later sent to FTP, in that way I don't have to use content conversation, to save performance...
I am on PI7.1 version so I have checked the options (Processing Parameters) for empty file handling in Sender/Receiver file communication channels.
Issue:- Though the target file is created but it always contain 1 byte(NULL character). Any ideas??
Thanks
Anshul

> In my scenerio, I am using Java mapping to name the target filename and creating text file that is later sent to FTP, in that way I don't have to use content conversation, to save performance...
>
The java mapping is genarating output as text file,right??have you tested your java mapping in NWDS or eclipse,because when you test in Operation mapping you will get error for text file,because it is not well formed.
if your java mapping genarating text files perfectly then file content conversion not required at all,just give file name in Communication channel.
> I am on PI7.1 version so I have checked the options (Processing Parameters) for empty file handling in Sender/Receiver file communication channels.
>
Why you have selected empty file handling??it is not required.

unselct empty file handling test your interface with real data.

Empty file in sender comm channel

i have issue with the empty files coming from the sender which are getting processed and getting saved in given file location.
Now the problem is,these files donot contain data and rather just gets outputted with header and trailer with some dummy data usually spaces,some zeros,-- like this...,this makes the file size of some 444 bytes or 834 bytes but as it is not having any data,we need to goto SXMB_MONI everyday,check for files,if its empty,needs to cancel them manually because it appears in red flag.
To avoid this,i was thinking of setting the empty file option in processing of communication channel to SKIp messages or delete messages.
Am i right in this approach?
From other thread:
"Currently when a process fails in PI due to an empty file the process needs to be manually set to u201Ccancelledu201D,where to locate in PI,what could be the problem and how it is to be solved.i have asked a similar question and hope that this error will help."
please reply and show me right way of resolving this.
thanks!
cheers!

Hi,
As per ur req, its nt possible in this way.
The empty file handling means the whole file is empty, the size is 0k.
So in ur req, empty file means Header and Trailer present, but no data Records.
we can achive this in following ways also,
1.write an adapter module, to check if at all there is atleast there is 1 Data record, if not throw exception there itself.
2.In the mapping check if at all there is any Data Record. If no Data Records raise exception and also the Alerts.

Empty File at Target Directory

Hi Experts,
I am dealing with file to file scenario, where file is being posted to the target directory depending upon the condition, which is mentioned in Java Mapping. The Java Mapping is tested and is successfull. But, the problem is PI is generating file with 1KB (only one space) ain the alternate folder(where it shouldn't go depending upon the condition).
The folder is having no space constraint and the file size is just 2KB.
Empty file handling mode has been set to ignore. still its being generated
Please suggest.
Thanks & Regards,
Sushama

Hi Suraj,
Here it goes::
for(int b=0;b<itemLineList.getLength();b++){
                         Node itemLineDetails = itemLineList.item(b);
                         NodeList itemLineDetailList = itemLineDetails.getChildNodes();
                         for(int c=0;c<itemLineDetailList.getLength();c++){
                              Node ItemDetailsNode = itemLineDetailList.item(c);
                              if(ItemDetailsNode.getNodeName().equalsIgnoreCase("MetaData")){
                                        NodeList ItemDetailsList = ItemDetailsNode.getChildNodes();
                                        status = checkIteminMDM(ItemDetailsList.item(1).getTextContent());
                                        if (status){
                                             getTrace().addInfo("in update");
                                             populateCreateorUpdateHashMap(ItemDetailsNode,"update");
                                        else{
                                             getTrace().addInfo("in create");
                                             populateCreateorUpdateHashMap(ItemDetailsNode,"create");

Process 0kb empty file and deliver to target directory

Hello Experts,
We had a requirements to process an empty file handling and send it to the receiver/target directory. We had configured to "Process Empty File" Handling and Write Empty File. The 0KB file polling successfully and archived to the directory with empty payload, but the message output was never created/sent to the target directory. In smxi_moni error message displayed:
<?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="">
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="MAPPING">CANNOT_READ_PAYLOAD</SAP:Code>

<SAP:AdditionalText />
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>Unable to read payload from the message object</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Since this is an empty file, there are no mappings involved. Is there a way to that we could check for 0kb file? If it is empty file, we want to pass/place the empty file to the target directory and if it is not empty, we want the message to process in the standard way.

Hi David,
"Since this is an empty file, there are no mappings involved. "
do you mean you didnt do the mapping at all cos it is empty file ?
though it is empty file still you need to do the mapping as usually,but when you check the option process the empty file both in sender and receiver adapter ,then it will process even an empty file comes.if you dont check these options and you get an empty file during the process then the mapping will fail.
in real time you don't know which one is empty file right,but her you know cos you are placing empty file.
I think you got to do all the steps you do in eneral for a scenario and top on that you have to check process empty file in both sender and receiver adapters,but you may not see the payload in SXMB_MONI.
but search in SDn you get lot stuff.
