PI 7.1 using FTPS as File Sender Adapter: Problem connecting to Server!

Hi
We are using SAP PI 7.1 and I am trying to connect to an FTPS Server, but always get the following Error in the log: "Channel FileReceiver: Error connecting to ftp server 'hostname': com.sap.aii.adapter.file.ftp.FTPEx: The control connection to the FTP server hostname timed out while reading the server reply."
I checked all the parameters and they seem to be ok! When I am using the same parameters with a WS_FTP Client Tool on the same server, I can establish the connection! Hostname, Port, User, Pass, etc must be ok ... I also imported the CA Certificate into the "TrustedCAs" KeyStore ...
We also checked if on FTPS Server side we can see anything in the logfiles, but it seems that PI (Fiel Adapter) does not send anything to the FTPS Server. On OS Level we see that a TCP Connection is established tho the Server on the correct Port and we also used a tool to analize if data is sent over the established connection, but there was no data :-o
Can anybody help me?
Thanks
Christoph

Hi Pavan
Access rights are ok ... how do I check if my PI Sysem supports FTPS? We have installed the crypto extensions and I also can select the FTPS Option on the file adapter. Is there anything else that must be enabled or configured?

Christoph

Cant do a file get from external server using file sender adapter with ftp

Hi all,
Up until now our company has only used the file sender adapter with ftp protocol to get a file from our XI server for processing and input the file into an integration process
I have a requirement to do an ftp file get from an external server
From our XI development server I can ftp directly to the external server and view the required directory using the command window via a DOS prompt (FTP open ...). So all firewall issues and communications are fine
Unfortunately I cannot currently pull files from the external server using the XI file adapter with ftp protocol from the XI development server AWB017
FTP Connection Parameters: External server name using port 21, Data Connection is Passive, No security, I supply a userid and password
Processing Parameters: Processing Mode is Archive (I tried test but this did not work either)
No messages appear in the RWB
Is there something else that I need to set up in order for the external ftp get to work via the XI file adapter?
Regards,
Mike

Thanks for your responses.
I have found the error messages in the File Adapter Monitor
Scenario 1
When I prefix the source directory with a forward slash, eg /Folder/Subfolder the error message is as follows
EST: Error: Error connecting to ftp server 'ip address': FTPEx: /Folder/Subfolder: The system cannot find the path specified
Scenario 2
When I DO NOT prefix the source directory with a forward slash, eg Folder/Subfolder a different error message is returned
Error: Retrieving file 'FILENAME.XML' failed unexpectedly: FTPEx: Folder/Subfolder: The system cannot find the path specified
At least in this scenario the adapter has been able to identify the file on the external FTP site but cannot retrieve it
Questions
I thought that the backslash prefix for the source directory was mandatory but I am receiving an error in each scenario
I receive the same error message whether the Processing Mode is 'Archive' or 'Test'
The logs on the external ftp server seem to indicate that I am simply connecting, sending username and password then quiting straight away. I am not issuing any commands that they can see
I thought that being a Sender adapter it would inherently execute a Pull or Get command
To recap, from our XI development server I can ftp directly to the external server and view the required directory using the command window via a DOS prompt (FTP open ...). So all firewall issues, communications, userid and password are fine
Has anyone experienced these issues?
Please advise on next course of action?
Regards,
Mike

Need help to Configure FTPS connection for File Sender Adapter

Hi,
I want to Configure, FTPS connection (Secured Connection) for File Sender Adapter. Could anyone please guide me, what Information I require to configure. I just want to know what Information should I request the team inorder the configure FTPS so that it can be deployed properly.
I have checked with [SAP Help Link|http://help.sap.com/saphelp_nw04/helpdata/EN/e3/94007075cae04f930cc4c034e411e1/content.htm] and while configuring the communication channel found that I need Keystore and the X.509 Certificate and Private Key. which needs to be deployed on the J2EE server by using the Visual Administrator.
Is there anything else, I need to configure.
Any help would be appreciated in this regard.
Thanks & Regards,
Varun.K

The basic things are Certificate/Keys which you already know. Usually it is enough for running a sceanrio.
However, if you have additional requirements, like FTPS for "Connection Security" for encryption, then you may need additional details like commands. Rest all settings are same as FTP.

File sender adapter (FTP) - processing mode "Archive"

Hello all
We're polling files from an external FTP server. For this I created a scenario on XI according to this thread:
When setting processing mode to "Archive" in the file sender adapter (ftp) it polls the file, stores it to the archive directory I specified and then tries to delete the file on the FTP server side. This returns me an error because we're not allowed to delete the retrieved files on the FTP server!
Because of this error the file adapter stops further processing and does not poll all the other files.
How can I disable this deletion mechanism while keeping processing mode to "Archive"?!?!?
We do not want to use processing mode "Delete" or "Test" and we don't see other options to influence this behaviour.
Thanks for any guideance on this one in advance!
Kind regards,
Renaud

Hi Bhavesh
Sorry for the late answer. Unfortunately I can't ask the application system to provide file names containing a timestamp within. The files are provided by an external partner and are retrieved by several others as well.
In the meantime I managed to achieve this:
In repository I created dummy data types, message types and message interfaces. No mapping programs and interface mappings!
In configuration I created the necessary communication channels (1 ftp sender, 1 file receiver) and the required receiver and interface determinations as well as the sender and receiver agreements.
The result of this is:
I'm able to poll some specific files via ftp from remote host. The file names are file1.arj, file2.arj, file3.arj and file4.arj. All 4 files have the same SourceFileTimestamp (e.g. "20060727T053900Z").
I'm able to store those 4 files 1:1 in a target directory with the same file names. Until here I did NOT need to follow this blog: <a href="/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14: The same filename from a sender to a receiver file adapter - SP14</a>.
As of this blog it is possible to access adapter specific attributes and make them available in message mapping using user defined functions. This way I'm able to get the SourceFileTimestamp from the polled files and use it in a message mapping. This way I'm also able to use it in variable substitution on file receiver adapter (syntax = "payload:root,1,fileTS,1") in order to dynamically create a directory with this syntax: YYYYMMDD.
So far so good... but the only remaining BIG problem now is, that as soon as the mapping is activated and assigned in the interface determination, the created files contain the XML payload instead of the original binary content. Where has it gone? How should the target message type look like so that it can carry over the original binary file content?
BTW: isn't it possible to post screenshots? Would be much more easier to explain things... so sorry to anyone if I wasn't clear enough!
TIA and best regards,
Renaud

Error Archiving File in File Sender Adapter using AF_Modules/PayloadZipBean

Hi everybody.
I have to pick a zip file up from ftp server, unzip an convert the file in xml.
Im using this modules in file sender adapter:
AF_Modules/PayloadZipBean --> To unzip de file
AF_Modules/MessageTransformBean --> file to xml
The problem is when I try to archive de file. Im getting this error and I dont know why (This path exists /out/ProcesadosSinError/)
Could not archive file 'test.zip' as '/out/ProcesadosSinError/20100518-091029-155_test.zip' after processing: java.io.FileNotFoundException: /out/ProcesadosSinError/20100518-091029-155_test.zip (A file or directory in the path name does not exist.)
Could it be that is not possible to archive with AF_Modules/PayloadZipBean?
Thank u so much

Hi Stefan.
Absolutely. This path exists. It's an absolute path from root. I can´t understand the error!!!!
Thanks!!!

File Sender Adapter with FTP protocol

Hi,
I implementet a file sender adapter with FTP protocol. There is a problem: the sender processes the files even if they're in use by another application.
I.E. If another application put files (via ftp) in the sender work directory (that is on ftp), the sender processes those files before their transfer is completed.
I don't want that this sender in a communication channel in PI 7.1, imports files in the system when they aren't completed yet.
There are some ways to block sender before it processes incompleted files (in an ftp)?
Thanks
Matteo

Hi,
File sender adapter provides a check for NFS mode
+Check this
To specify additional parameters in the adapter configuration, set the Advanced Modeindicator.
● Msecs to Wait Before Modification Check
Enter the number of milliseconds that the adapter must wait before it checks whether the files have been changed.
This parameter is not available if you have selected File Content Conversion as the Message Protocoland then made an entry under Recordsets per Message that splits an input file into several messages.
This parameter is applicable only for the File adapter. If you enter a value in this field when configuring the sender FTP adapter, it will have no effect.+
Other approach can be to apply OS level checks

Using subdirectories in file sender

Hi there
Is is possible to search in all subdirectories in your file sender adapter's source directory? I know you can specify the different directories using the Advance Selection for Source File but i'd like to know if you can specify somehow to have it search the source directory and all it's subdirectories?
Thanks,
Jan

There is no standard way to do this. You may however have some OS script to perform this. The script may search the file and copy it at one location from where PI can pick it up.

Prateek

File sender adapter: trigger mail if file is not there

Hi,
I have an scenario where I have a file sender adapter, and I need to look for a file in a specific folder from a specific FTP site.
If the file is not present there, I need to trigger an alert to let some people know that the file was not found.
Is this possible? If so, how should I do it?
Thanks!

You could also write an abap in your PI system to call the function 'EPS_GET_DIRECTORY_LISTING' against the FTP site/folder/filename(s) at a required interval if you don't want to use a BPM. This abap could also send an email if you so desired.
The general theory should be that if you can do something a simpler way then don't use BPM's if you can avoid them.

File sender adapter is not working

Hello All,
We are facing a problems with file sender adapter. Communication channel is not picking the files from the directory, but the status in RWB for that channel is 'Functioning'. We are not sure whether the channel is locked or any other problewm with adapter. (In Alternate option, we have created copy of that channel and when it is activated, it picked the file )
Can anyone help us how to identify whether channel is locked and any other solutions in this case.
Regards,
Sreenvias.

Hi Srinivas,
The file adapter ( The respective channel) is definitely locked in PI . Ideally for each polling interval a lock is being created and once the processing is over , the lock should be released/deleted automatically to allow further polling interval. If the lock is not released by the system automatically,further polling will not happen as expected. ( This may affect all sender file adapters as well. I would recommend to do a check in al sender file communication channels)
You can see/delete the locks in Visual admin.
Go to Server>Services->Locking adapter and click refresh
The entries for file adapter ( with name $XIAFFileAdapter) should be deleted by selecting those particilar entries and click delete selected locks.
If you have more than one node, then same should be done in all server nodes.
The temprory solution would be creating/copy the existing channel in ID with same properties and assign it into particular sender agreement.
But, the lock may be created again which potentailly stops all your file based interfaces. Hence i would suggest to use Timeout parameter avialable in file sender adapter which termiates FTP session as you defined, This should solve your issue permanently.
The FTP server do have thier own time out settings but if you don't defne any particulat time out in PI, the FTP server forcefully disconnects the FTP sessions which created locks in PI.
Hope this solves your issue.
PS: The same bahaviour would expected for all sender JDBC adapter as well

File Sender Adapter - Multiple Source Directory

Hi all,
I have the following file to IDoc Scenaraio:
The source file might be in any of 3 directories in source system and so created file sender adapter as follows:
File access parameters:
Source Directory : Directory1
File Name         : Filename*.XML
Addiontal Directory:
Directory2    Filename*.XML
Directory3    Filename*.XML
The porblem we are facing is the file adapter is picking the file from Directory1& 2 and not from Directory3.
If the change Directory Order in adapter as follows:
File access parameters:
Source Directory : Directory3
File Name         : Filename*.XML
Addiontal Directory:
Directory2    Filename*.XML
Directory1    Filename*.XML
... then file from Directory 2 & 3 is getting processed and not from Directory1.
Any thoughts on this will be greatly appreciated.
Thanks
Sarat.

Why use BPM for this?
Instead write an abap program to pick from any of 3 directories in source directory and place it in the shared XI folder and configure your file adapter pointing to XI shared folder...shecdule the abap report for every 5 min..
Wanna know more /people/sravya.talanki2/blog/2005/08/23/sender-xi-ftp-adapter-with-regular-path-expression-150-abap
Or write OS level scripts for doing same.

Semantics File Sender Adapter to determine which files to retrieve

Hallo,
does anybody has experience with this semantic?
Thanks in advance,
Frank
From the FAQ-List of file-adapter(Note 821267 , Question 27).
Q: Which semantics does the File Sender Adapter apply to determine which files to retrieve from an FTP server?
A: Up to and including SP13 the File Adapter will issue an NLST command (see RFC 959) with the configured source file name scheme as first parameter to the FTP server. It will try to retrieve any of the files returned by the FTP server in response to this command.
Starting with SP14, the File Adapter will issue a LIST command with the configured source file name scheme as first parameter to the FTP server. If it is able to parse the returned result (which is the case for UNIX- and Windows-style directory listings), it will retrieve any of the returned files. If it cannot parse the result, it will fall back to the pre-SP14 implementation and use the NLST command as described above.

Frank
We are on SP12 and have had problems with this and specifically, the FTP server on Solaris, not being fully RFC959 compliant.
We've had to get a different FTP Server as we were returned *.xml no file or folder found instead of 550 *.xml no file or folder found.
This increased the polling to the server, and filled up the ftp logging file, which intern filled up the partition and crasehd the server.
We got round this by installing http://www.proftpd.org/

Scheduling File Sender Adapter

Hai expertise,
 We need to send image files from different local PC's (whose IP address is dynamic) to Document Storage System through XI.
1) we have to use HTTP sender (Java program which pick current IP address of system and file names from folder to XI in XML format).
2) XI has to pick the files and depends on response from BAPI files has to be moved to other folders in local machine (from where XI has picked the files)
 Is there any way to pick the payload value to one feild of File sender adapter?
 will it work through Adapter Specific Message Attributes?
 But ASMA is for dynamic folders and dynamic filenames we need to set dynamic FTP IP address to FTP Server name of File Sender adapter.
 Is this functionality be achieved without adapter module creation?
 One more approach we though is that "XI will get XML data of IP address where file resides and file names in the form of XML, which we are polled by server proxy and using that IP address in proxy can we use do FTP copy and moving files from one folder to other depends on BAPI response". Will this work as the BAPI as to execute in backgroung to get files from local windows based machine to sever for FTP copy????
File sender adapter has to be triggered, when HTTP sender sends the data to XI, Is this possible???
Can we use File Sender adapter, when HTTP sender sends the data to XI in the same interface?
Picking files from static folders, filenames but dynamic FTP Servers, is this possible through standard File Sender Adapter?
Please advice.. its urgent...

File Sender Adapter - File overwritting in the Archiving folder

Hello Experts,
I am doing File sender to proxy Receiver Async Scenario.
In File Sender adapter, i am using the Archiving option by spacifying the
Archiving path.
Files are picked up and archiving happen successfully.
Problem is: - once the File is picked up and archivied into the Archiving location
If end user again rectifies some data in the same file and place it in the source directory
then i am getting the following error in RWB Commu. channel monitoring.
Failed to archive file 'File1.TXT' as '/Input File location/File1.TXT' after processing. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 550 File not renamed. File already exists. You may delete the existing file and then rename.u2019 For details, contact your FTP server vendor.
I know this is because of File sender adapter is trying to archive the file with the same name(File1.txt) in the archiving location.
My Question: - Is there any option to allow the File sender Adapter for overwritting the
File in the archiving location.
Thanks & Regards
Jagesh

check if there is proper rights to over write files in the archive folder.
The problem seems to be that the rights/authorization is not there. Else the adapter usually overwrites files in the archive folder unless you use the timestamp option.
Archive
Files that have been successfully processed are moved to an archive directory.
u25A0       To add a time stamp to a file name, select the Add Time Stamp indicator.
The time stamp has the format yyyMMdd-hhMMss-SSS. The time stamp ensures that the archived files are not overwritten and it enables you to sort them according to the time that they were received.
u25A0       Under Archive Directory, enter the name of the archive directory.
u25A0       If you want to archive the files on the FTP server, set the Archive Files on FTP Server indicator. If you do not set the indicator, the files are archived in the Adapter Engine file system.

How to handle flat file with variable delimiters in the file sender adapter

Hi friends,
I have some flat files in the ftp server and hope to poll them into XI, but before processing in XI, I hope to do some content conversion in the file sender adapter, according to the general solution, I just need to specify the field names, field seperator, end seperator, etc. But the questions is:
The fileds in the test data may have different amount of delimiters (,), for example:
ORD01,,,Z4XS,6100001746,,,,,2,1
OBJ01,,,,,,,,,,4,3
Some fileds only have 1 ',' as the delimiter, but some of them have multiple ','.
How can I handle it in the content conversion?
Regards,
Bean

File sender adapter: archiving not possible with transp.prot "filesystem,

Hi XI gurus,
in my FILE sender adapter I want to archive the processed files to a separate sub-directory of the "in" directory.
It works if I use transport protocoll "FTP" with a specific user
but it don't works when I use transport protocoll "file system (NFS)".
the xi user has all permission on the directories.
file system is on a UNIX machine.
Has anybody an idea why archiving only works with transf.protocoll FTP ?
Thanx very much in advance
regards
Hans
