File Adapter - Check file exist before performing read

Is there a feature in the file adapter or invoke activity for SOA 11.1.1.5 that performs a check to see if a specific file exists before it performs a read function? If file does not exist then move onto to next step, if it does then read it.
I am trying to do this in 1 step instead of performing a listing of the directory first before perfomring the read.

Hi,
When you read a file, using the synchronous read file, you have to point to a file (file name, directory...). That way, when you are executing the invoke activity, followed by a FileAdapter, it's either the file exists, and you read it, or it's not exist and you don't read it.

Sender File Adapter with file conversion

Hi guys,
Im using a Sender File adapter with file conversion. The message to be processed has a structure with fixed lengths and in your content are some values that needs to be ignored.
An example:
value1 value2 value3
I want to ignore value 2 but I cant find a parameter for that! Do I need to define dummy fields on my data type and ignore those fields during mapping? Or there is a specific parameter for that?
Thanks in advance,
Ricardo.

hi,
there always is another way:)
you can import the whole line to one field
and cut it inside the adapter module
(then you can define start and stop of the substring that you need to use)
but of course it's not standard even though it's quite easy to achieve in java

Error in Receiver File adapter using File content Conversion

Hi,
I am getting the following error in the receiver file adapter.
Conversion initialization failed: java.lang.Exception: java.lang.Exception: Error(s) in XML conversion parameters found: Parameter 'statement.fieldFixedLengths' or 'statement.fieldSeparator' is missing
I am using the below parameters for FCC:

Please let me know where i am going wrong.
Thanks,

Hi Aparna,
I feel the problem in your content conversion parameters is with
statement.fieldNames and ignoreRecordsetName
When you are confirguring receiver file adapter for file content conversion the above one is not required. Please refer below link for details on configuring content conversion in file adapter

XI30 File Adapter - check for (NOT) incoming file

Hi!
We use XI30 SPS15 and have the following challenge: We expect every
week on a certain day a file coming from a customer. So far so good.
But now we want to check whether such a file has really come within a
given period of time and if not, we want to take some action (e.g.
trigger Alert or s.th. like that).
Business Background is: If the customer does not send the file or he
sends it too late, we cannot bill him in time, thus increasing our DSO.
Is there any mechanism within the XI to check things like these and to
trigger an alert? I've read the File Adapter Documentation as well as
the BPM documentation but I could not find any hint.
Any help would be great. Thanx!
Regards,
Volker kolberg

hi volker,
this is not supported in standard but...
you can do it very easily with standard ABAP job scheduling
- you schedule a job (every week, day etc.)
which starts a raport that send a RFC (or abap proxy call to the XI)
- then the RFC starts a BPM and inside it triggers a
java proxy that checks for a file
- if the proxy finds the file then if copies it to some other folder (which is monitored by another flow)
- if it doesn't find the file it triggers an error - sends mail or anything
the only thing you need to code is a few lines in java
to check the existance of a file + copying nothing else:)
this is the easiest way I believe till now <= Sp15

michal

File adapter validate file checking directory for files

Hi Gurus,
We have requirement. There are 3 directories (Processing, Error and Archive)in the Source side.SAP PI need to pick up a file called "abc.txt" from the processing tab.
But there is a condition.
1. If "abc.txt" file exists in the "Error" directory then Not process the interface.
2. If there is no "abc.txt" file in the "Error" directory then validate the file "abc.txt" in the "Processing" directory. If the file is not according to the validation rule then move the "abc.txt" file to the "Error" directory and then stop the processing.
3. if the above two conditions are ok then move the "abc.txt" file to "archive" directory and send the file to PI.
Please help me to achive this requirement.

Hi Kevin,
You need to use the option of "advanced selection for source file" in the source tab of sender comm. channel.

File adapter(write files with same extension as we read them)

Hello
I am trying to read file as an attachment using file adapter (it can be of any extension .pdf,.txt,.xml)
I want to write this file using file adapter with the same extension i.e. whatever is read as it is....I am least bothered for reading the content inside the file so am reading it as an attachment..
Please if anyone knows the answer..reply....

I ran into a similar issue. As a workaround we ended up just using java to write the files out. When the File Adapter attempts to write out a file it first writes that file to a temp file and then copies that to the appropriate directory.
I believe that when two or more threads were attempting to write at the same time the write was failing for one (but appearing to work in the console logs). I think a race condition may be created when two threads attempt to write using the File Adapter for access to the temp file. I contacted my oracle rep about it but they are always pretty worthless so I havent ever heard anything back concerning the issue.

OSB File Transfer check file status

Hi,
I have to read a file from a directory using a proxy service (file protocol).
Sometimes the proxy takes the file before it is finalized. It can be very big and take a long time to complete its writing.
Is there any way to check the status of the file?

the process which generates the file should use an extension NOT polled by OSB while writing the file, and once completed it should rename the file to the extension polled by OSB
otherwise you can use a file trigger pattern, which is supported by the JCA File Adapter

XI Receiver file adapter : Dyanmic File PATH

Hi,
Appreciate if someone could help me on the issue below:
I have a receiver File adapter with a dynamic target directory as per below:
Target directory: /test/YYYY/MM/DD
the value for YYYY (Year) , MM (Month) and DD (Date) will be the date when the file being transfered from the sender.
Appreciate if someone could help me to achieve this. I know we can use the variable substitution however it doesn't allow us to set a systems field such as sy-datum.
Cheers,
ZAB

Hi,
Populate this value in your payload , and then use Dynamic File Name concept of File Adapter.
The dynamic filename generation concept is as follows.
In your filename field. just give a variable with % symbols. (eg: %file% ).
Now, under the option Variable Name Substitution, you can give how the value has to be created.
It can be your interface name, sender service name, etc or it can be some value dynamically from your payload.
For the former, your give
message:interface_name ,etc
and for the payload part you give,
Payload: "your element root which u wanna acecss"
Just check this link out,
http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/content.htm
And read the contents under variable substitution and it will help you understand the concepts better.
If you have any clarifications, do get back,

One file Adapter NXSD file dynamic

Hi all,
I will get different inputs based on the input request ID i have to do write the file using file adapter .
so the question is if i have 10 files is it necessary to create 10 File adapters or can i achieve this using a single File adapter and multiple NXD or XSD files in a folder .
select the xsd or NXSD at runtime based on the input request ID.
The best thing with this approach is even for a new transformation request i will just add the xsd or NXSD in the folder and update the DB no need to create a file adapter from scratch.
Thanks
Phani

Hi,
You cannot change the XSD for a file adapter at runtime....u can choose to write an opaque file with an native format is not required option checked.

File adapter input file format

Here the communication scenario is as follows: read a file and send a message via XI to an inbound interface.
A file adapter service has been defined. Message protocol 'file content conversion' has been chosen for the file adapter service. Next the file format has to be defined in communiction channel settings.
Is it possible to define the input record structure in the file to be red itself?
The first line will list all column names. The data records will follow in line two up till end of file.
Regards
Klaus

Now I can add some more information to the facts.
In XI 2.0 the adapter engine was used to connect the integration engine to external systems. The adapter engine converted input file contents to a XML message. The structure of the records in the input file has to be defined. There was one option to read this structure from the first line of the file itself. This option was called 'fromFile'.
Now the current situation in XI 3.0 is that the integration engine reads the input file. Conversion of file contents is still available but the option to read the record structure from the input file doesn't exist anymore.
Does anybody know whether I am right and this functionality isn't available anymore or how to achieve the desired system function in XI 3.0.
Regards
Klaus

File Adapter - Create File Name from Payload

Hello,
I have a scenario where I'm sending deductions to external vendors (wage types) following a payroll run, via XI. Part of the message payload includes a data element 'Vendor Name' (e.g. Zurich Insurance). When the XI File Adapter creates the file, I want to create the files as /usr/file/xi/<Vendor Name>.csv
How to I pick up the 'Vendor Name' from the message payload and pass this into the "File Name:" field of the "File Access Parameters in the File Adapter communication channel configured?

CONFIGURE FILE ADAPTER ,get files one by one.

HI, I have cinfigure one system of FILE ADAPTER TO JDBC ADAPTER, is working OK, but I need to Know how configure The FIle adapter to get files one by one from the folder , I have the channel configure between 30 seconds, but when come to look for the files has them all ... I need to get one by one the files.
Help me... RGRDS.

Hi ,
What is the operating system of your PI server sytem? If its unix/linux you can achieve this using shell scripts, for windows systems you need batch files. The script/batch file would run in background continuously. It will check how many files are present in a directory (say xyz) . Then one by one transfer the files to directory(say abc) from where PI picks up files at regular interval. you need to use "sleep()" command in script so that the script puts files after some time interval say 90 seconds. The polling interval of comm channel in PI should be set less than sleep time interval of the script.In file sender adpater configuration please set the Processing Parameters -> Processing Mode-> Delete/archive. The script before putting a file in "abc " checks presence of any files. If there are some files it goes to sleep mode for few seconds and continues checking unless "abc" is empty. Then the script moves(as we do cut and paste in windows) file in "abc" directory.

Anupam

File Adapter - Large file

Hi there,
I am using a 6.5 MB file and the file adapter is not picking up the file. The status is still green in the adapter monitoring and says process started.
Any insights into this issue.
[email protected]

HI,
It should pick 6.5 MB etc.. Check the read/write etc permission of the file/folder
Are you getting any error ? Anyway , just check the Read-Only option in the file adapter configuration.
Also look into log from Visual admin for the File adapter
