FTP to external system

Hi,
I am try to establish a connection to the external system. I am using the FM "FTP_CONNECT" for connection in my ABAP program. But somehow I am not able to connect.
I am getting an error message saying "Attempting to connect to (HOSTname) fail".
I have checked user authorization and it seems everything is fine.
Do I need to pass gateway parameters in this FM as this is the external system (They are optional)? Currently I am not passing anything in all three gateway information.
CALL FUNCTION 'FTP_CONNECT'
     EXPORTING USER = USER
               PWD = PASSWORD
               ACCT = ACCOUNT HOST = HOST
               TRACE = FTP_TRACE
               GUSER = ''
               GPWD = ''
               GHOST = ''
     IMPORTING HANDLE = HANDLE
               ERROR = CERROR
     EXCEPTIONS SYSTEM_FAILURE = 1
                COMMUNICATION_FAILURE = 2.
Appreciate your early response.
Thanks,
Samay

Hi Samay,
You need to setup RFC Destination (SM59). If you don't have authorization, please ask BASIS to help you. Otherwise please follow this steps.
When you define an RFC server program (usually an executable on a server) as RFC destination, you choose either 'START' or 'Registration'. 'Start' means the SAP application sending anything to this destination will trigger this program, while registration means this program will already be running (like a service) and have already registered itself to SAP server.
Once you have defined your RFC destination as of type 'registration', you should execute this exe with the syntax
"pgmname.exe -a<ProgramID>
-g<Gateway Host>
-x<Gateway Service>
" where programID shall be the same as the RFC destination name (I think) and gateway host and service is from the app server where you are registering this destination,
to have it started as a service and registered as the destination to the SAP server (which you can afterwards see in SMGW txn).
If you want this program to be started when something is sent to this RFC destination from SAP, make it of type 'START'.
Hope this will help.

  • Sender File Adapter  not able to get file via FTP from an external system

    Hi,
    I have a Sender File Adapter using FTP which polls a server every 10 seconds looking for a file ".xml".  The adapter will connect and pick up the waiting file, but sometimes the adapter not able to get file via FTP from an external system. The file is on the server, but despite the polling, the adapter does not pick up it. There is no return error.
    The connect mode is Permanently and the transfer mode is Binary.
    Can you help me?
    Thanks.
    T.

    Hi Teresa,
    does this case appears with a file size higher the others?
    Personally, I do not recommend to have a polling under 1min.
    10s could be too just, if the file is not small and/or if the file server is far (several kilometers) to where the Adapter Engine is, and/or this file server is beside a firewall. Do not forget also that, with previous points, you could have like a conflict, betwen the 1st polling and the 2nd polling, if in less 10s PI adapter has not enough time: to connect to the FTP server (several Km), find the file (perhaps among 100 other files in the directory), go back to the file to Adapter Engine server (several Km again), convert your file to XML message (with a complex Content Conversion), then check the XML structure, and when all that is done, return back to FTP server (several Km), to archive the source file... Well It's my understanding of a FTP exchange with FILE adapter...
    If you really need a 10s polling, that's mean your have a pseudo real time interface. In that case, in my mind file should not be used! but we should use a Web service, JDBC JMS (any exchange without a physical object like a file). For me, it's a non-sens to have a file in that case.

  • FTP file on Appserver to an external system from ABAP

    Hi,
    I am trying to FTP a file that my program writes to the APPSERVER directory. I used FTP_CONNECT, FTP_COMMAND and FTP_DISCONNECT.
    I am able to connect to the external system and change to the directory where I have to write the file using cd. The problem arises when I use lcd command to switch the local directory. Although, i specify the path, lcd /usr/sap/icomm/iface/outbound/, on execution of this command, the system points to my C:\Documents and Settings\rkademani\SapWorkDir.
    How can I make it point to my appserver?
    Further, this program will be scheduled as a background job in Production. I have tried to schedule this as a background job, even then it gives me the same error.
    Please help. Thanks in advance.

  • External system to SRM

    Hi SRM specialist
    <u>Scenario:External system --> SRM</u>
    Now we are examining how to do the Interface.
    Firstly PO data is created in External system and this data will be needed to transfer to SRM.
    <u>Question</u>
    What can we do when we will do the Interface from External system to SRM?
    (IDOC? XML? FTP?)
    Please tell me about it.

    Hi,
    As far as I know if ur talking with SAP with SAP system than connection would be RFC and the communication in the ALE IDOC right.
    But if ur talking with SAP with NON SAP system than the connection would be through some middleware like XI.
    Note:- But in some case u can pass your SAP IDOC into XML format to the other NON SAP System provided that the system should be in programmed in such a formate that it can understand and mapped the details as per the business requirement.
    See IDOC can be send in different format right like.
    1) Files Formate,
    2) TRFC Formate,
    3) XML File,
    4) XML Http,
    5) CPI-C,
    6) ABAP-PI
    Is this is the ans ur looking for please revert.

  • How to distribute Modelview to external system such as Webmethods

    Hi All,
    I have a scenario like this 
    I  have to send Delivery idoc to two external systems
                       Triggered through
    SAP               output 'ZEXA'.
    system        -> DESADV ->     External system (A)
                        Triggered through
    SAP               output 'ZEXB'.
    system        -> DESADV ->     External system (B)
    The distirbution model allows me to add only one external system as the receiver at a time for the message type DESADV,  I cannot distribute the model view also ...
    How can i achieve this, I dont want to create any Z-message types.. Your suggestions will be higlhy appreciated.
    Regards,
    Krishnakumar

    Hi KrishnaKumar
    As far SAP distribution model (ALE ) is concerned SAP does not identify any system as SAP system or External system. It only identifies the system as logical system. And when the distribution model distributes the idoc using RFC and port setting, at that time it actually identifies the system as SAP or External.
    So as far as distribution model is concerned you can add external systems also but these should be present as logical system in SAP tables.
    And as Shital said there must be some middleware in your design, it could be PI also as well as some FTP server.

  • Read/Open a file in SAP DMS from an external system

    Hello Sap Gurus,
    I want to read/open a file in SAP DMS from an external system . External system is basically a non-sap system.
    Can this be achieved through an RFC..
    Does anyone know of any BAPI's/FM's that can be called from an external system (non-sap system) through RFC which will open a document which is stored in SAP DMS.
    Regards,
    Madan Shetty.

    Hi Madan,
    If you want to view documents from an external system, there are many ways of achieving this.
    It depends on the solution that you are approaching.
    Few methods that I have come across are, OData services, Custom RFC Function  Modules, to retrieve document attachments.
    FTP is also a possible solution.
    Please let us know your exact requirement.

  • Scenario: Idoc - XI - external system (Idoc)

    Hello,
    I am trying to send an idoc from an sap 4.6c system to an external system. The external system is supporting idcos with trfc. This scenario is currently working with ALE. Now i have to set XI between these two systems.
    My problem is to set up the communication channel in the integration builder (configuration) for the external system. The idoc is waitung in XI to transport. So the step XI-> external system causing problems.
    My settings are:
    adapter type: idoc
    transport protocol: idoc
    message protocol: idoc
    adapter engine: integration engine
    rfc destination: xyz (is working fine)
    interface version: sap release 4.0 or higher
    port: ??
    sap release 46c
    My problem is the port. should i set up a port in idx1? But the external system is not an sap system and so i dont have a client.
    In XI i have defined a port in transaction we21 (transactional rfc) for the external system with rfc destination xyz. But if i enter that port in communication channel i got error messages.
    Thanks for any help.

    Hi christian,
    i'm also working in IDOC scenario between ECC to XI to MDM, if u have any document or snapshot then pls fwd it to me.

  • HUGE amount of data in flat file every day to external system

    Hello,
    i have to develop several programs to export all tables data in a flat file for external system ( EG. WEB).
    I have some worries like if is possible by SAP export all KNA1 data that contains a lot of data in a flat file using the extraction:
    SELECT * FROM KNA1 ITO TABLE TB_KNA1.
    I need some advices about these kind of huge extractions.
    I also have to extract from some tables, only the data changes, new record, and deleted records; to do this I thought of developing a program that every day extract all data from MARA and save the extraction in a custom table like MARA; the next day when the programs runs compare all data of the new extraction with the old extraction in the ZMARA table to understand the datachanges, new records or deleted record.. It's a righ approach? Can have problems with performance? Do you now other methods?
    Thanks a lot!
    Bye

    you should not have a problem with this simple approach, transferring each row to the output file rather than reading all data into an internal table first:
    open dataset <file> ...
    select * from kna1 into wa_kna1
      transfer wa_kna1 to <file>
    endselect
    close dataset <file>

  • Is it possible to integrate LSO 600 with an external system without SAP PI?

    Hi,
    as asked in the title, i am wondering if it is possible to integrate LSO 600 with an external (non-SAP) system without using SAP PI/XI. The external system is a middleware application which can handle RFC functions, IDocs besides the usual web service communications.
    However, i don't know how LSO and SAP PI are integrated so i wonder if their interfaces are such that instead of SAP PI another middleware could be used.

    Web Services are used. If you were to implement the services in your 3rd party middleware and configure SAP to call it, I suppose it is possible. The external course catalog can be used for CourseEnrollment and LearningProgress. See the application help for details. Don't expect to receive support from SAP with such a setup however.

  • Integration of Financials with external systems

    Hi,
    I am strugling with an implementation where the client is not sure if Oracle Financials suits his business processes
    Overview of situation on Hand:
    We do not have the product installed as yet at the client site
    Products of Oracle Financials to be used :General Ledger, Account Receivable, Account Payable, Fixed Assets,India Localization Patch
    Products of Oracle Applications NOT available for use :
    Purchasing, Inventory, Order Management
    (All these areas are being covered by developing a customized Bespoke system)
    1.     Is it possible to use Oracle India Localizations (with regards to the excise functionality, for e.g. claiming of ModVat, the various excise registers that are to be maintained for e.g. RG23 A, RG23C,etc ) in the above situation (without implementing Purchasing, Inventory, and Order Management?).
    2.     Further, while passing the Vendor’s Bills (in Oracle Payables), one of the criteria for PO Matching is to check if the ModVat has been claimed. Is this functionality available in Payables with the India localization patch?
    3.     Does Oracle India localization cater for VAT requirements?
    4.     Is an Open Interface available to transfer Purchase Order data from external systems to Oracle Purchasing tables (which are shared by Oracle Payables the names being PO_HEADERS, PO_LINES, PO_LINES_LOCATIONS, PO_DISTRIBUTIONS, PO_DISTRIBUTIONS_AP_V (VIEW OF PO_DISTRIBUTIONS), PO_RELEASES (Blanket Purchase Orders), PO_LOOKUP_CODES) at transactional frequency? However, if the oracle purchasing module is not being used, can the interface tables of Purchasing be used?
    5.     An open interface (Payables Open Interface) is available in Oracle Payables to import the Invoices from external systems. While importing these invoices, does the system expect to have the Purchase Order data in the PO tables mentioned in the point above?
    6.     Is an Open Interface available to transfer Quantity Received/Accepted data from external systems to PO_line_locations table to enable carrying out of 2/3/4 way matching of Purchase orders with invoices? Can the 4 way mathcing be carried out in AP by just importing Purchase Order data??
    7.     Can the Credit Card Transaction Interface be used for uploading employee expenses / advances settlement (not carried out via credit card) directly from feeder system?
    8.     Is it possible to use Open Item interface (including import concurrent program) even though Inventory module is not being installed ? If yes, then we would like to use this interface for updating Item master from bespoke system..
    9.     Can Auto Invoice API be used to import invoices from feeder system / legacy system (via RA interface Tables) into the Oracle receivable invoice tables? Is order number as column a prerequisite for successful completion of Auto Invoice API?
    10. Where should the Masters be kept....OF of Bespoke
    eg. Employee master, Inventory Item Master etc.
    11. What is the best strategy for keeping the data in Bepoke and OF related to Masters in sync?
    I have got various answers to these questions .....but some seem to contradict each other.

  • Calling a web service in external system from SRM

    Hi folks,
    A web service is created in the external system and I need to access this web service from a BADI. Can you tell me how can I call this web service (the external system is giving me a URL) and how I'll get a return. Please let me know in detail.
    Thanks,
    Prem

    Prem,
    Hi. You can call the service via HTTP protocol. Pass them values (SET_DATA), and receive a response (GET_DATA), via xml/html.
    In your code you would need to create the xml data to pass them, and evaluate the returned xml.
    Process...
    Data setup
    1) Create the XML to send them
    Working with the external service
    2) Open the HTTP connection
    2a) cl_http_client=>create_by_url (IF_HTTP_CLIENT)
    2b) lr_client->authenticate
    3) Call the to send them the XML
    3a) lr_client->request->set_data
    3b) lr_client->send
    4) Call the lr_client->receive to return the response
    5) Close the connection lr_client->close
    Data evaluate
    6) Evaluation the returned XML and process.

  • Cannot "Complete" Service Desk Messages in External System

    Hello Solution Manager Experts!
    I have an issue where we had two Solution Manager Service Desks and needed to consolidate into one.  As part of that exercise, we set up an external service desk relationship between the old service desk (call it SID OLD) and the new service desk (call it SID NEW).  When sending the service desk messages from OLD to NEW via the action (Send to External Service Desk) we can only set the status to "Accepted", and the status "Completed" is grayed out for the service desk message that resides in the NEW system.  In the NEW system, under the Transaction Details-->Transaction Analysis there an error indicating that the message can only be closed by the external system (OLD).  However, in the OLD system, the original message is already set to "Complete", and I am no longer able to do anything with the original service desk message.  Even if I make another copy of the message in the OLD system and resend the copy to the NEW system (as status "new"), I still cannot mark the service desk message "Complete".  In the OLD system, even of this copy of the service desk message is something other then Complete, I cannot mark it complete and synchronize with the new system.  I get an error in the old system that says that "The problem message is locked in external system SM_NEWCLNT030_SERVDESK", which is obviously a reference to the RFC destination for the new external service desk.
    How can I go back into the NEW system and change the message to "Complete"?  Additionally, even if I could close the message in OLD and synchronize with NEW, I am curious how I would get around this issue if the OLD Solution Manager service desk needed to be decommissioned, and was no longer available, this would still be an issue of closing out service desk messages to a status of "Complete".  Is there some kind of program I can run agains certain service desk message numbers which will "break" that relationship with the OLD service desk so I can set those messages that originated in OLD to be "Complete" in NEW?
    Any service desk messages that are created directly in NEW can be closed out to "Completed".  This is an issue that is only a problem with  messages that originated in OLD.  I hope this makes sense. 
    Your input is greatly appreciated.
    Thanks!

    I found a workaround by going into the status profile in the NEW system, double clicking on the CONF status, changed "To be distributed"  to "allowed" and "set".  Then I backed up one screen so I could see all my status's; and then in the last column of the CONF status in the column labled "Trans.", I set it to RELE instead of FINI.
    This enables me to set the "completed" messages from my legacy (OLD) system to "completed" in my (NEW) system.  Once I have all the status's set, I'll set the status profile entry for CONF back to the way it was.

  • Create Support Message from external system

    HI experts,
    I would like to change the Create Support Message screen(Menu->Help->Create Support Message) and add three fields namely: Category, Subject and Solution Number because currently these fields are not populated in the Service desk if I create message in this way unlike in using NOTIF_CREATE tcode where there are selection fields for these.
    Also, I'm creating the support message from an external SAP system and the messsage is sent to the Solution Manager system. The NOTIF_CREATE tcode does not exist in the external system as well as the whole package DSWP.
    Please let me know you rthoughts on this.
    Thanks
    Eric

    Hi guys,
    Thanks for your answers... But is it possible to call transaction NOTIF_CREATE from an external system?
    I have done something already so that those 3 fields will be automatically populated for a message sent from an external system.
    I changed the screen and called FM BAPI_NOTIFICATION_CREATE(a remote enabled FM which is the one being used by transaction NOTIF_CREATE to create a message) inside FM BCOS_SEND_MSG.
    I populated the category, subject and solution in the FM export parameters as well as the solution number in the sap data table. I put a destination also..
    This FM calls another FM DNO_OW_CREATE_NOTIFICATION which is the one being used from the external system but do not cater the functionality to send the 3 fields that we need.
    As you will notice, there are lots of standard objects that I've changed. =)
    My problem now is that the system data sent is the same with the system data if you create the message using NOTIF_CREATE. Some system that were sent when a message is sent from an external system is missing but at least the sap system and client ID is sent. There is no external reference number also. But hopefullly, the users will accept it. Can't find any other solution to this.
    Thanks,

Before testing we have uploaded the external server certificate in PI system. it was working fine with * HTTP 200 OK* message. since 2 days we are facing the ICM_HTTP_SSL_ERROR while testing the connection. when we telnet from PI to the external system using the port no.443, its getting connected.
    so any idea why it started giving the error.
    We have check out this forums but of no help.
    [ICM_HTTP_SSL_ERROR|ICM_HTTP_SSL_ERROR;
    The trace file dev_icm says

    Hareen,
    We checked the the note 1318906 and followed the steps but error persists.
    Could you please advice more on this.
    Rahul,
    The note you mentioned is for different error "ICM_HTTP_INTERNAL_ERROR".
