SFTP adapter

Hi Experts,
I have SFTP to FILE adapter without ESR objects scenario.
I just need pick file from remote location and drop in to receiver side with same file name.
In this what ever I am picking up source files via SFTP adapter need to generate the same file name in receiver side.
When I have choose ASMA in SFTP adapter it is failing receiver side (File) . File name is not found like .
I have put file name is XYZ_*.* in source in SFTP adapter and Target side *.* in File adapter
this configuration is not working getting error in receiver side.
Can you please suggest to me any alternate solution for this scenario.
Regards
Tahir

Hi Tahir,
SFTP Sender Adapter :
File name : In case of .txt file give the filename as ".+\\*.txt",in case of .csv file give the filename as ".+\\*.csv" and in case of any other file format give the filename as " ".+\\*".

How to acheive this in Sender SFTP adapter ?
Kindly guide me
Renu

Hi Renu,
Unfortunately as of latest release of SFTP adapter. Arching is not possible :(. really dont know why :).
as a work around what you can do is create a scenario as 1 sender and 2 reicever.
here: 1 sender: will be the sender fileadapter which will pick the file from souce.
1st receiver: will be a receiver file channel which will palce back the file in the source Archive folder.
2ed Receiver: this will be the actual receiver to which the data has to be given.
Or write a Module in Sender adapter which will archive the files in new location.
Note: Here i am assuming that each time the source creates a new file with same name which contains new data in it everytime.

Picking file in sequence/Queuing   in sender SFTP adapter.

Hi Experts,
I am using SFTP adapter in sender side, it has no option of quality of service ( EOIO) and queue name as we have in FTP adapter configuration .Is there any predefined module provided by Sap which i use in the modules Tab in communication channel configuration to get the functionality of queuing ? just like we use strictXMlto plain bean etc.
I have 3 files which needs to proccess in a sequence one after another in order.I CANT USE BPM or Even FTP because of Security reasons.
please share you ideas.
Regards,
Anika

Hi all,
I have tried using AF_Modules/DynamicConfigurationBean in module tab present is the sender SFTP adapter with the attribute qualityOfService.
parameter name                  Parameter value
     key.0                         insert http://sap.com/xi/XI/System/Messaging qualityOfService
    value.0                        ExactlyOnceInOrder
But in Moni i dont see the 3 messages didnt go in the same queue.But when i double click and open the dynamic configuration present in the soap header section i can see the values which i given in the module parameter.
Is there any way i can change the quality of service to EOIO at runtime ? how to change the default EO to EOIO.

Sender sFTP Adapter - SSH Key

Hi All,
I have a small doubt regarding Sender sFTP Adapter. This is what we have done to connect with one of Vendor
1.     Basis created a SSH key in NWA for Vendor and sent to them.
2.     They linked the SSH key with user name and asked me to use the same.
3.     We got the firewalls openepd b/w PI and Vendor
4.     I provided the same detail in sFTP adapter, but I am not able to connect,
I am getting below error:
Error: Cannot connect to SFTP server. Host=########, port=22, username=#####. Private key store=########, private key alias=piPKCS12. Timeout=300000 msecs. Absolute home directory=.: KeyStoreException in Method: getPrivateKey( KeyStore, String, String ). The requested keystore type is not available in the default provider package or any of the other provider packages that were searched. (Software version: 3.0.14.2)
Please provide your inputs.
Regards,
Sachin Dhingra

Hi,
The first thing you have to do is use the same userid and the pwd and try to connect to the vendor system from your application layer and see if this is connecting or not. If there is a problem in connection then there are few steps that you have to follow. Below are the steps you need to follow:
1. Open the port from your Vendor side as well as open the port from your XI system(there might be two ports)
2. Generate the key of your vendor system and one you started login to the system then it will ask to instal the key , so acept it.
the IS people can help you out over here.
3. Try to push the one dummy file in that location manually using the command in application layer.
4. check the authorization in the target directory and try to provide the proper authorization,, 777 is used for full authorization.
5. use the same useid and the pwd and then try from your xi system processign a dummy file.
hope this helps.
cheers,
jay

How to configure SFTP Adapter in XI?

Hi All,
How to configure SFTP adapter in XI?, It would be great if anyone sends a step-by-step documentation on the same.
Thanks in advance

Hi,
About SFTP .
1) SFTP (Secure File Transfer Protocol)
"SSH File Transfer Protocol" or SFTP is a network protocol that provides file transfer and manipulation functionality over any reliable data stream. It is typically used with the SSH-2 protocol to provide secure file transfer. SFTP encrypts the session, preventing the casual detection of username, password or anything that is being transmitted. One key benefit to SFTP is its ability to handle multiple secure file transfers over a single encrypted pipe. By using a single encrypted pipe, there are fewer holes in the corporate firewall.
SFTP:
As per the latest SAP PI/XI support pack, it does not support SFTP via File Adapter.
So alternative approach to cater this requirement from XI is to make use of Unix Script at OS level to transfer the files from/to third-party systems.
Inbound Interface - i.e. third-party system ->XI->SAP:
File is transferred to a folder in SAP XI landscape from the third-party legacy system using UNIX Script with secured protocol. Once the file is ready in the XI landscape, File Adapter will poll this directory and file is picked up by NFS protocol.
Outbound Interface i.e. SAP->XI->third-party system:
XI is responsible for writing a file into a folder in the XI landscape. These files are transferred to the third-party system by executing UNIX scripts with secured protocol i.e. via sFTP.
Pre-Requisites:
Public key should be exchanged between external systems and the PI system.
UNIX shell script has to be developed and scheduled.
Advantages:
Highly Secured.
Ability to handle multiple secure file transfers over a single encrypted pipe .By using a single encrypted pipe, there are fewer holes in the corporate firewall.
Disadvantages:
Two-Step process i.e. XI>Temporary folder>External System and vice-versa
Files have to be temporarily stored in XI server.
Multiple failure points i.e. XI and Unix script execution
Maintenance of an external UNIX script.
Difficulty in monitoring the execution of the shell script as it cannot be monitored thru XI.
Need to generate keys and install it in the SFTP site as a pre-requisite i.e. SFTP clients must install keys on the server.
SFTP uses keys rather than certificates. This means that it can't take advantage of the "chains of trust" paradigm facilitated through Certificate Authorities.
Files from the XI server should be deleted/archived in a periodic manner to increase the disc space so that it will increase the performance.
Note: UNIX shell Script can be executed as a background job or' can be triggered from SAP XI through OS command at File adapter level.
Check the links.

Query regarding sftp adapter

Hi
Is there any way we can use dynamic configuration with sftp adapter ?
Requirement is that I need to retrieve input file name and use that somewhere
but for sftp sender I could not locate adapter specific message attributes.
Does that mean its impossible to retrieve file name during runtime?

Hi Akhil
have a look on this links
Standrad File adapter shipped with XI does not support SFTP. You can may be consider using FTPS ( File Transfer Protocol using SSL/TLS ).
Check this link for further info,
http://help.sap.com/saphelp_nw04/helpdata/en/0b/9a50465ccf84479e39a6d50c90fb3f/content.htm
For HTTPS and FTPS, you need to define if your communication will have certificate authentication, user authentication, none or both. User/password you enter in the adapter parameters, it's simple. For certificates, you need to import (load) it on Key Storage service, service_ssl view, on Visual Administrator (or create the key pair certificate on XI and then sign then on some Certification Authority, on the same service). Check http://help.sap.com/saphelp_nw04/helpdata/en/f1/2de3be0382df45a398d3f9fb86a36a/frameset.htm for further information.

Receiver SAP SFTP adapter-errorlog on SFTP server

Experts,
I am using receiver SAP SFTP adapter to connect to an SFTP server and send files.Receiver SFTP server is a VMS system.I could able to write the files to home directory of the user that has been given,but apart from writing the files I am seeing warning log file in the the target folder on SFTP server like below description.I am giving dot(.) in the file path to write the files to the default directory that has been assigned to the user given by receiver SFTP server team.
WARNING: ssh_file_server_receive_proc: platform cannot stat() filename /home/dir1/dir2 ./TestFile(TestFile is my file name) .
Just to test,we placed files in the receiver SFTP server using same user and password as the PI recv SFTP channel with command line and winsCP client tool,but we don't see any error logs on the server with WinSCP tool or command line transfer of the files.Log file with above warning is generating only when we place files on the server using SAP SFTP adapter in the recv channel of PI.
Please let me know,if you have any insight or seen similar issue.
Thank you,

Hi Poonam - Blogs on SFTP : Just search for SFTP and filter by blogs/documents.. you can find many..

http://scn.sap.com/docs/DOC-35572
I read in some of the SDN forum that SFTP adapter doesnt have the capability to read the files from multiple directories. So, if we get any requirement to read the files from multiple directories using sftP, why could be a possible solution for this requirement?
>>> Yes. It is only possible with NFS.
You have to define multiple channels/interfaces...

Dynamic directory for Sender SFTP adapter

Hi All,
Hope everybody is doing fine.
I need urgent help for below requirement for SFTP adapter ,client requirement is
We have deployed the SAP security Add ons (PGP-SFTP) for one of the requirements in our PI system (PI 7.11 SPS 11).
The SFTP adapter is configured to read files from the source system.As per the guidelines from the source system , we need to determine the source directory dynamically and then poll the files.
The source folder structure looks something like this :
\Archive\FROM_System\<yyyy>\<mm>\<dd>\Interface1
\Archive\FROM_System\<yyyy>\<mm>\<dd>\Interface2
That is we need to pick up the file every day from a new folder, say, for 24th July 2013 - \Archive\FROM_System\2013\07\24\Interface1
25 July - \Archive\FROM_System\2013\07\25\Interface2
Will the PI SFTP adapter support this kind of requirement? As this is sftp sender adapter Operating system level command option is also not available.
Do we have any standard module/Bean to dynamically change directory name in the sender SFTP adapter?
i will really appreciate your quick help.
Thanks
Monica

Hi Monica,
Yes it should work. Did you check this thread:
http://scn.sap.com/thread/3376137
Also refer to the following documentation link for the SFTP sender adapter (scroll down to the adapter specific message attributes):

Seeburger SFTP adapter

Hi
I want to transfer the file from one location to another locatoin through Seeburger SFTP adapter, is it possible?, If yes could you please suggest how to do and provide any documents/links.
By using File adapter we can send the data
/people/william.li/blog/2006/09/08/how-to-send-any-data-even-binary-through-xi-without-using-the-integration-repository
Like this i want to send the data through SFTP.
Thanks
Ramesh

I had a same question long time back.
The way to do this is - Exchange the server keys ( Your admin can generate it)
Install the keys ( server keys ) from the target system in your source server ( where you have SFTP adapter installed). If you have user id and password you can choose in the drop down of the SFTP adapter.
Yes, FIle adapter is configured to pick the file and virual receiver.
Another pointer was - there are some fields which are mandatory like mapping where you can use DUMMY.
To send to the target - configure the receiver adapter.
Make sure your fire wall is open for the port needed for SFTP.

Sending empty files using SFTP Adapter

I am trying to send empty files using SFTP adapter. The interface has to send the file whether its empty file or containing data using SFTP adapter. I am using BizTalk Server 2013 R2. Is it a bug or the hotfix is already there for this issue.

The issue here is not your SFTP not able to send 0KB files, but the file receive adapter that is receiving the file. The file adapter deletes 0 KB files and doest not transmit it further.
If u have a ftp receive for example you should be able to send 0KB files.
If u have a custom file receive adapter , is it handling 0KB files ?
