Connection to SAP R/3 46B through EP

Hi All
I installed following products but don't know how to connect SAP R/3 system through webdynpro.
EP : 6.0 SP10 (Only Java instance)
OS : Windows 2000
DB : Oracle 9i
R3 : Version 46B BASIS SUPPORT PACK 30
OS : Solaris 8
DB : Informix 7.31 fd2x9
Am new to NETWEAVER programming my desire is to connect
SAP and fetch data from SAP pl guide me.
Thanks in advance
Sanjay

...and for "classical" portal development (i.e. PAR files), first create a system object in system administration --> system configuration --> system landscape and set all configuration parameters for your R/3 system accordingly there.
Next decide on you you like to implement SSO to this system (user mapping or SAP logon tickets). For the latter one, some additional steps need to be performed on the R/3 side. Please check service.sap.com/securityguide for this or do a search on the SDM forums on "sap logon tickets". There also are various nice weblogs on this, e.g. Quick Guide for setting up SSO between EP and R/3
Now for the "data fetching" part. This will require doing an RFC call from EP to your R/3 system. For this, you usually utilize SPA Java Connector (JCo) through JCA. This archive https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/jca on ep6 building portal applications.zip
contains all neccessary information.
Hope this helps, if so please do not forget rewarding points.
Regards,
Dominik

  • SAP DB Connection from SAP BI on HP UNIX to MS SQL External Database

    Dear All,
    Greetings!
    I have a scenario to configure a SAP DB Connection from SAP BI System on HP UNIX 11i to the external legacy system MS SQL 2000 Enterprise for data upload. I am interested in connecting the SQL server as a Source System to the BI System.
    I read through documents mentioning about installation of a Client driver in the SAP BI System, I also downloaded the JDBC client software and tried installing the same, but the steps as mentioned Setting the CLASSPATH or connecting to the server did not work.
    Please help me in connecting the SQL Server as Source System, I would like to know in detail about the same - so kindly help me with the links to documents and guides about the same.
    Thank you
    Regards,
    Vineeth Damodar

    Short answer: this does not work.
    Long answer: To connect directly to the database you need
    - a database client for the source system
    - a database interface library for the source system
    Both of them are not available for HP-UX if the target database is SQL server --> doesn't work.
    What you can do is: add a Windows application server to your  BI system (heterogeneous installations work and are supported) and add there the database client and the database interface library.

  • RSA1 DB Connection from SAP BW to external SQL Server databas.

    Hello,
    I am trying to connect our SAP BW system with SQL Server Source System through DB Connect in transaction RSA1.
    Our BW system is running on Windows and MaxDB platform, therefore have I already added the latest dbmssslib.dll library to the kernel for SQL Server.
    But the connection does not work anyhow, I recieve the error "Database error -1 at CON > [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does > exist or access denied." and I am quite sure that my input parameters are correct.
    Therefore I wonder if someone has run into a similar problem and what the problem could be?
    Best Regards,
    Niklas Sandstedt

    Hi,
    I am sorry that my case was assigned to wrong forum.
    That should now have been corrected, however my problem still remains unsolved in one of our systems.
    I found note 178949, which fixed the problem in one system. But even though the system setup seems to be identical, the two systems appears different.
    The following has been done for both systems:
    1. Upgraded kernel to 701 version 111 and added dbmssslib.dll and dbmssslib.pdb files
    2. Created Logical system in BD54.
    3. Tried to create DB connection in transaction DBACOCKPIT.
    In the third step, the setup fails and I receive the following error message when I test the connection:
    Database error -1 at CON > [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not > exist or access denied.
    Database error -1
    All profile parameters AL11-directories also seems to be correct in both systems, so both should find the dbmssslib.dll file.
    One issue that I see is in DBACOCKPIT, the checkbox for "SAP Systems with basis release" is unchangeble and marked. This however, I think was changed in the other system automatically when the connection was established successfully.
    Has anyone run into the same problem?
    Best Regards,
    Niklas Sandstedt

  • BO 4.0 - Database error: Unable to connect to SAP BW Incomplete logon data

    Hello Experts,
    I have enabled a 'SSO to database' between SAP BW and Business objects by referencing to the documents related to below link.
    [http://wiki.sdn.sap.com/wiki/display/BOBJ/HowtosetupSSOagainstSAPBWinSBOBI4.0forLDAPusers]
    I have created a universe connection with option 'use single sign on when refreshing reports at view time' and have created a universe on top of my BEx query by log-in to the universe designer tools using my LDAP account.
    Now when I run the report with either SAP account or LDAP - I am able to run a adhoc webi report on this universe and get data either through the webi rich client or via BO 4.0 Info-view/Launch Pad.
    But the issue is that when other users are trying to run webi queries on this universe either through Info-view/launch pad or rich client by log-in via LDAP Authentication - they get the below error: I have given SAP_ALL to this user for time being and also have done the necessary configuration for 'simple user format' in CMC so these user has 1 account with 3 alias definitions: Enterprise, SAP, R/3.
    Database error: Unable to connect to SAP BW server Incomplete logon data -
    If the user logs on into the BO 4.0 Info-view/launch pad or webi rich client using his SAP authentication than he is able to run and retrieve data.
    I also get a dump in the SAP BW system - I analyzed the dump in SAP BW using st22 tcode and it gives the error short text as - Incomplete logon data and run-time error -  CALL_FUNCTION_SIGNON_INCOMPL
    Desired outcome:
    I want the users to log-in to webi rich client or BO 4.0 Launch pad/Info-view using their 'LDAP'  authentication and run reports against the universe on SAP BW/BEx query without any errors or additional username/password requirements.
    Can someone please tell me if I am missing any steps/configuration and guide me to achieve the above mentioned desired result ?
    Any help in this matter would be greatly appreciated.
    Thanks & regards,
    CD.

    Hi Simone,
    Thank you for the reply.
    Here are the things done by me.
    1. Generated the keystore file and imported it in BI 4.0 CMC on  SAP Authentication Option tab
        ([http://wiki.sdn.sap.com/wiki/display/BOBJ/GeneratekeystoreandcertificateforSAPBO+BI4.0])
        ([http://wiki.sdn.sap.com/wiki/display/BOBJ/SetupofSAPSSOServiceinSAPBOBI4.0+CMC])
    2. Generate the certificate file cert.der and this cert is imported in SAP BW with STRUSTSSO2 transaction.
        ([http://wiki.sdn.sap.com/wiki/display/BOBJ/ImportSAPBOBI4.0certificateintoSAP+BW])
    3. BW Roles/Users have been imported into CMC.
    4. SAP Users and LDAP users are mapped/aliased with each other using the registry key method
        ([http://wiki.sdn.sap.com/wiki/display/BOBJ/HowtomapSAPusersandLDAPusersinSBOBI4.0+CMC])
    I haven't explicitly configured STS (Security token service) as STS is a part of Adaptive processing server (APS) and I have verified that by going to servers in CMC and then to analysis services.
    I have searched for SAP OSS notes related to my issue but couldn't find any note related to SAP BW SSO with Business objects 4.0. Most of the notes are relevant for BO XI 3.1 environments.
    Thanks & regards,
    CD.

    Whether your problem is solved?
    We have the same problem in BO Mobile.

  • BO Analysis for Excel – How to connect to SAP BW

    Hi Gurus,
    We recently upgrade to BO 4.1 (from 3.1).  And want to start to use Analysis for Excel.
    We are little unclear how to connect from Analysis for Excel to SAP BW 7,3.
    From Analysis select “Select Data Source” Then get a pop-up “Logon to SAP BussinessObjects BI Platform” with User, Password and Web Service URL.  All those are blank.  For the Web Service URL there is a message “Error while checking availability of SAP BussinessObjects BI Platform system”
    If choose “Skip” then get SAP Logonpad and can log on to BW.  From there I can choose the BW queries directly.
    What is the best practice to connect from Analysis for Excel to SAP BW?
    Is it not possible to connect to the BO server?  And choose OLAP connection from there to connect to BW?
    If so, is something missing in our setup?
    Regards,
    Reynir

    Yes you need to define an OLAP connection of you are connecting to BW through the BIP - see tutorial http://scn.sap.com/docs/DOC-20625
    You can also connect directly to BW without going through BIP
    I also recommend searching before you post per SCN rules - there are many posts about creating OLAP connections

  • URL Reporting connecting to SAP R/3

    Hello,
    We have Crystal Reports that connect to ABAP Function Modules in our R/3 4.7 system as the data source. To minimize the number of user prompts, we use URL Reporting to pass all the required parameters for the report. The one thing we have not been able to do is specify data connection information in the URL. We currently get around this by setting the data connection information (SAP server, system #, client #, etc.) in the Database Configuration for the report in the CMC. The downside to this is that the report is now limited to running against a single SAP client.
    Is there a way to specify the SAP connection information (server, system #, client #, etc) in the URL Reporting string? I know it can be done for SQL data sources through the USER- and PASSWORD- commands on the URL, but is there a similar way to specify SAP connection information?
    Our reporting environment is BOBJ Enteprise XI 3.1, reports are developed in Crystal Reports 2008.
    Thanks,
    Byron Clairoux

    Hi,
    that is not possible. the connection is part of the report.

  • Connect to SAP gateway failed Connect_PM  TYPE=B

    Hi experts,
    I get the following error when i ping through JCO destinations on portals.
    com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM  TYPE=B MSHOST=imtsapdev01 GROUP=CLUST R3NAME=DMI MSSERV=sapmsDMI PCS=1 LOCATION    CPIC (TCP/IP) on local host with Unicode ERROR       partner '127.0.0.1:3310' not reached TIME        Tue Jan 27 16:39:54 2009 RELEASE     700 COMPONENT   NI (network interface) VERSION     38 RC          -10 MODULE      nixxi.cpp LINE        2823 DETAIL      NiPConnect2 SYSTEM CALL connect ERRNO       10061 ERRNO TEXT  WSAECONNREFUSED: Connection refused COUNTER     1
    However my JCO destinations were working perfectly until recently. I checked on the logon group. I have one called CLUST, which i use for this purpose.
    I have also checked both service files and they have the following for the ECC server im connecting to.
    3610 because its system number 10 i am connecting to.
    sapmsDMI 3610/tcp
    From the JCE destinations screen i cannot even ping the server. I can though when i log on to the server through remote desktop.
    thanks and regards

    as a reply to nishants posts.
    goto rz70
    give hostname -->
    service --> sapgw00 (sapgw(instance number)
    execute it
    click on yes
    check rfc call (success or failed)
    I have done this. i left hostname as "blank" gave service as "sapgw10"
    The following is what i  got as the output.

    so i guess its not successful. when i look at rz70 of a server where this works correctly its not succsessful either
    if it is success then technical system name will be in sld
    to restart sld --> /sld --> administration --> stop server --> restart server
    or check in VA --> SLD data supplier value --> Runtime
    I checked this and i do not see aa problem. you have configuration status as valid and send reult as Success
    Services file is locted on OS level of R3 system--> Goto --> Start --> Run -> (type)Drivers(enter) --> etc -> (here is services file)
    check ur r/3 server entry is there or not,
    I have the followng in the service file for the server
    sapmsDMI 3610/tcp
    if not add it

    Hi Experts,
    when ilook at the remote gateway properties in SMGW this is what i see on the R/3 server. ive looked at my other system which i can connect to and there isnt much of a difference in the parameters. How can test this to see if it works?

    I know it has something to do with the entries in the services and hosts files of the portal server. Please guide me on links from help.sap.com on this.

    HI Dagfinn,
    Very helpful answer. Thanks.
    When you say :
    4. Normally, the sap system should be registered in DNS, and you should need any. --- How do I check if my SAP system is registerd in the DNS? Is there some detail explaination on this.
    Also,
    I have these observations :
    1. I checked the services file on my portal server and the entry for "sapgw00 3300/tcp" is maintained there.
    2. There is no entry of my SAP ECC box in the  hosts file of my portal server.
    3. The group PUBLIC is not maintained in SMLG transaction.

    Hi Lakshmi ,
    As rightly mentioned by Ganesh, this is supposed to be handlled by Basis+hardware support team.
    What you can do as temporary solution, use RSRT for Query Monitor.
    And use query display as BEx/HTML, this way you can atleast see the result of query.
    Hope it helps.

    Hi Aligan,
    Thant's correct, you have to develop a service on your EP and then you can change the UME persistence (user creation etc).
    Now you can write a J2EE app which will call your service to cater your requirement.
