How to Connect EP6 to Legacy Systems like RPG, DB2, AS 400 ?

Hi All,
Being new to portal, have a requirement to build an application in EP6 which requires pulling data from Legacy systems like RPG,DB2,AS 400.
Is there any innovative way to accomplish this in EP6.
Thanks,
DK

Hi Deepak,
portal can connect to DB2 atleast - not sure about the others. For connecting to DB2 you will require the JAR file which would give you the API to create the connection and execute the queries of your application. Like other database Jar files - the DB2 jar file is also located in <drive>:\usr\sap\<sys id>\<instance id>\j2ee\cluster\server0\bin\ext\com.sap.datadirect folder with the name P9db2.jar. I guess you can create a DataSource with the following JARs from this folder in the Visual Admin. The JAR files required would be:
P9db2.jar, P9base.jar & P9util.jar.
Once the datasource is created you can use that in your java code for creating connection and firing queries.

Shubhadip

    Hi Everyone ,
    We are integrating SAP EP and BOE . We are facing SSO problem ,as there are 2 system in same environment .
    Suppose we have XX1 and XX2 as BW backend system . IF Default entry on server is kept blank then we get :
    "u2022  Account information not recognized: No SAP system was passed as part of the user name and there was no default system defined. User credential validation cannot continue. " error.
    Whereas if we give XX1 as defaut system on server , then SSO is not happening we as are XX2 users .
    Anyone has any idea on how to connect to multiple backend system in the same environment .

  • How to transfer data from legacy system  to SAP

    Hi ,
    Conversion of legacy data into SAP can be uploaded using a standard SAP Tool called LSMW ( TCode:LSMW).
    the below link gives a brief explanation of the LSMW tool
    http://tutorialsap.com/abap/sap-lsmw-tutorial-with-steps-to-create.html
    There are various methods to upload data within LSMW. If the number of records are very high like Article Master or  Conditions for Retail the IDOC method must be used.
    Standard IDocs
    1. Article Master - ARTMAS
    2. Conditions - COND_A
    3. Source list - SRCLST
    4. Customer Master or WRF3/WRF6 tables - DEBMAS
    5. Vendor master- CREMAS
    Etc. Use transaction code WE60 to see the structure of each of the idocs. New enhancements can be done for the idocs if the required field is not available.

  • How to connect SAP R/3- System with SAP NetWeaver Portal (2004s)?

    Hello to all,
    sorry, can someone help me? How can I connect SAP R/3- System with SAP NetWeaver Portal (2004s)?
    Thanks and regards,
    Galyna

    Hi,
    In previous link contain this info
    This describes how to connect an SAP R/3 system to SAP NetWeaver Portal using an iView
    1)      Go to System Administration
    2)      Go to System Configuration
    3)      Go to Portal Content (Right Side Panel), open that folder.
    4)      Right Click on Portal Content, a Panel is displayed select "System (from Template)".
    5)      That will display a new view on right side, now select "SAP system using dedicated application server" from
    the existing templates. (Other templates are possible - for example, load balanced or through a SAProuter connection string).
    For this exercise, we'll use the simplest type.
    6)      Choose next
    7)      Give the System Name and System Id (which are mandatory fields) incase you want to give any brief notes
    about the system then give them in the "Description" field.
    8)      Open the Newly Created System.
    9)      Now when you want to create a New System, you have to fill four Properties they are:
    "Connector" - contains basic connectivty details
    "Internet transaction Server (ITS) - if you wish to use SAPGUI for HTML and/or IACs",
    "Web Application Server" - if you wish to access BSPs and/or Web Dynpro for ABAP and
    "User Management".
    You also need at least one "System Alias" has to be defined from the Display drop down menu.
    Make sure you have set end user access in the Permissions drop down menu to all users who need to access the system
    10)  Select "Connector" property, now fill the required fields such as:
    a)      Application Host (should be fully qualified hostname) - Give the R/3 "Application Name",
    which can be obtained from the SAP Logon Pad (check what R/3 system you are using, right click on it , go to the properties,
    it will open a window which has the Application Server Name.
    b)      Logical System Name - Give the logical name as defined in the backend system
    c)      SAP Client - Check the Client in the backend system and give the appropriate number (3 digits)
    d)      SAP System ID(SID)* - Check the R/3 properties and give the check for System ID
    e)      System Type* - Since we are connecting to R/3, select SAP_R3 system.
    f)       System Number - This is a two digit number that you can find in the SAP Logon Pad
    11)  Select "Internet transaction Server (ITS)" property, now fill the required fields like
    a)      ITS Description à Give some Description
    b)      ITS Host Name - Same as "Application Host" of R/3 (when integrated ITS) and should be attached with the
    port number of ITS Server (to get port number detailed description is given below). ex: hostname : port number
    c)      ITS Path - To get the path along with the port number you have to Log on to R/3 system. Use the
    Transaction Code "SICF", it opens a new window go to:
          default_host -> sap -> bc -> gui -> sap -> its -> webgui -> SAP GUI for HTML -> right click on
    that and click "Test Service'. This will open a new window, on the address bar you will find the "port number", and
    the path something like (/sap/bc/gui/sap/its/webgui). Use the path after the port number.
    d)      ITS Protocol - There are two protocols "http" & "https", select the appropriate protocol which is
    visible when you opened "Test Service" window.
    12)  Select "Web Application Server" property , now fill the required fields like
    a)      Web AS Description -> Give some Description
    b)      Web AS Host Name - same as ITS Host Name
    c)      Web AS Path - usually /sap/bc/bsp/sapd)*    
    Web AS Protocol - should be same as the ITS Protocol.
    13)   Select "User Management" property, now fill the required fields like
    a)      Authentication Ticket Type - Since we are not using SSO leave the field
    empty i.e. put in select mode. (Please note that longer term you will probably want to use SSO)
    b)      Logon Method - Select UIDPW.
    c)      User Mapping Type - In case you have administration rights then you choose "admin" or in case you
    just have user rights then choose "user", better go for "admin/user".
    14)   Since all the required fields are filled appropriately now create a System Alias name, this can be done by following steps:
    a) go to Display -> Select "System Aliases" give some Alias Name, let's call it "SAP_R/3"
    15)  Now that System is created we have to create a iView which will display the given Transaction Code.
    16)  Go To "Content Administration".
    17)  Go To "Portal Content".
    18)  Go to Portal Content (Right Side Panel), open that folder
    19)  Right Click on Portal Content, a Panel is displayed select "New" -> iView
    20)  Select iView template, click next
    21)  Select "SAP Transaction iView" from the list of templates available. Click next.
    22)  Give the iView name and iView ID. Incase you want to give any brief notes about the iView then give it in "Description" field. Click next
    23)   Select "SAP GUI for HTML" radio button. Click next
    24)  Now select the system which you have create "SAP_R/3", give some Transaction Code, say SE12 (Dictionary Display). Click next and Finish.
    25)  Now Preview the iView
    26)  You will see a new Window where in SE12 Dictionary Display window is displayed.

  • How to Connect Backend R/3 system to EP 2004S

    Hi Friends - I am new in the EP field. We have installed EP.
    We want to connect to backend R/3 system from EP.
    I have created a system for the backend R3 ECC system. But the connection test is failing.
    "Test Connection with Connector
    Results
    Retrieval of default alias successful
    Connection failed. Make sure user mapping is set correctly and all connection properties are correct."
    Also the ITS and WAS tests are also failing.
    "SAP Web AS Connection
    Results
    1. The system ID is valid
    2. Retrieval of the system was successful
    3. The system object represents an SAP system
    4. The following parameters are valid: WAS Protocol (http) WAS Host Name (mb1es1005.idcsap.com:8001)
    5. HTTP/S connection failed"
    Can you pls guide me on how to configure the same?
    1. What are the step wise configurations I have to do?
    2. Is there any configuration I have to do in the R3 system? ike RFC connections and other settings?
    3. What are the settings I have to do in the EP system?
    Pls guide me on the same.
    Thanks in advance and warm regards
    Purnendu

    Hi Maiti,
    first thing is, first try with user mapping, if you succed in this then only go for login tickets method. both are different ways to connect to R/3 systems under SSO.
    create system by selecting template for "sap system using dedicated application server".
    then add the follo parameters:
    Application host: ur FQDN for R/3 system
    Gateway host: same as Application host
    Gateway service: sapgw00
    Logon method: select Uid/PW
    Remote host type:select 3
    SAP client: enter ur SAP client (001 generally)
    SAP SID: ur SID
    SAP Sys number:00 (or 01 )
    server port: 3200
    System type: select R/3
    user mapping type: select admin/user
    validate connection: no
    (no need to set ITS and other properties they are optioal).
    this much settings are enough. Then add a system alias for your system, by going in properties and select System Aliases.
    now go in user admin, search for your current user, click on modify, click on user mappings..select your system, provide login id and password for your R/3 system.
    save it.
    Go ahead and create iVIew (Transaction iView) even though your connection test fails, it works. it will connect to ur backend R/3 system via iView without any error.
    hope this helps you...

  • How to connect 2 SAP BW systems to one SAP BO?

    Hi
    Two companies from the group I'm working for wants to connect their BW system to corporate BO system.
    BW system are independent of each other. My concern is about SSO authentication.
    Will it be any problem to configure SSO between BO and BW if 2 BW systems are defined there?
    Does any one face this kind of lanscape challenge before?
    Any other issue should I be aware of?
    Thanks

    There are different possibilities.
    Since you are saying that you already have a connection with SWIFTNet (Make sure you also have a Swift Alliance Gateway account without which you will not be able to post messages to SWIFTNet.), I assume that you also have the SAP BCM in place.
    Now if you want to place a message via FIN/FileAct, you can write a custom program to create a file that is in line with the Swift standards. You can find the details of the file formats, etc.. from the SWIFT site. For FileAct, additionally you will have to create a .par file along with the .FTA file. This is for the FTA to understand the parameters.
    Once that is done, you can place the files in a folder and configure the FTA to pick up these files. This is for FileAct.
    For posting messages via FIN, you can have another program to post these files to SAG (SAG supports web services) via SOAP.
    Hope this helps.

    Please help.
    Thanks.

    Hi,
    If u want to know that legacy system has received the message or not. then it wil be two step process.
    One is ur actual process and other process is the ack from legacy system.
    Once the data is received by Legacy system then ask legacy system to send the Response message to XI saying that message is received. if legacy system is down then in that case there wil not be a Ack response hence u will come to know that message is not reached to legacy system.
    Thnx
