Webdynpro Model import error - missing R3NAME or ASHOST

Hello,
We have a new NWDI setup for our portal development for ESS and MSS components.
(NWDI 7.01 SP 05 and EP 7.01 SP05 and ECC 6.0 )
I am trying to import a WD model (adaptive RFC) into an NWDI project and am getting the following error.
I get this error after searching for the available FMs in the model import wizard, and when I am at the final screen.
However, If I create a local project, I am able to import the model (same FM and same backend system) without any problem.
I guess the problem is with only the NWDI projects and some thing to do with NWDI or SLD connection to the backend system.
The JCo destinations are setup correctly and I have tried using a couple of different logical system names and there is no change.
Does any one have any idea on what I am missing?
Appreciate your response.
Thanks,
Shanti
Here is the error:
[Warning]:     Creating a connection with Metamodel language <de> failed.  Continuing with language <en>

Hey Puneet,
The problem seems to be more weird.
The JCos are fine .... and I am infact using the same JCos in both the cases.
I can not only import the model in a local project but also import the model in an NWDI project for a different DC.
Somehow the problem is with creating the model in only one of the DCs in the ESS SC.(ess/quotas)
Well, I finally went ahead and finished creating the project (ignoring the error I was getting) and the model works fine after import and deployment.
At this point, I am not sure what the problem was but it does not impact my model at runtime. Every thing works fine as expected.
This seems like a bug ... and the error is somehow showing up unnecessarily ...
Thanks,
Shanti

  • Bulk import error - Missing required attribute ‘fullname’

    Folks,
    I am having trouble trying to bulk import some users.
    I have the following file for import (cut down from what I really want to import):
    command,user,waveset.resources,password.password,password.confirmpassword,global.firstname,global.lastname,global.fullname
    Create,”user1”,”myLDAPresourcename”,”passwd”,”passwd”,”myfirstname1”,”mysurname1”,” myfirstname1 mysurname1”This works using “Accounts->Launch Bulk Actions” with Action set to “From Action List” and everything else on that page left at the default value. The correct data appears in IDM and the LDAP resource.
    Now if I try to import the following file, in which the user does not have a first name, I get in to trouble:
    command,user,waveset.resources,password.password,password.confirmpassword,global.firstname,global.lastname,global.fullname
    Create,”user2”,”myldapresourcename”,”passwd”,”passwd”,””,”mysurname2”,”mysurname2”
    The error message is:
    com.waveset.Util.WaveSetException: An error occurred adding user ‘uid=user2,…..’ to resource “myLDAPresourcename”.
    com.waveset.util.WavesetException:  Missing required attribute ‘fullname’Clearly the import file contains a column for ‘fullname’ (column 8) and a value for ‘fullname’ in the only row of data “mysurname2”. As far as I am concerned it is perfectly valid for a user not to have a ‘firstname’; but they must have a ‘fullname’.
    I have tried using an import file without a value for ‘fullname’, but with a ‘firstname’ and ‘lastname’ like this
    command,user,waveset.resources,password.password,password.confirmpassword,global.firstname,global.lastname,global.fullname
    Create,”user3”,”myLDAPresourcename”,”passwd”,”passwd”,”myfirstname3”,”mysurname3”,””This works. The correct data appears in IDM and the LDAP resource and IDM has generated a ‘fullname’ value of “{Firstname} {Surname}”. Trying to leave out the ‘firstname’ and the ‘fullname’ gives the same error as above.
    The configuration of my resource (in summary) is
    objectclasses:
         top
         person
         inetOrgPerson
    Account Attributes:
         accounted     -> uid               [required]
         password     -> userPassword
         firstname     -> givenname
         lastname     -> sn               [required]
         objectClass     -> objectClass
         fullname     -> cn               [required]
    As an experiment I have tried reconfiguring the resource so that ‘fullname’ is not marked as required.
    Importing user1 and user3 still works and still creates the correct data in IDM and the LDAP resource.
    Importing user2 now gives a different error:
    com.waveset.Util.WaveSetException: An error occurred adding user ‘uid=user2,…..’ to resource “myLDAPresourcename”.
    javax.naming.directory.SchemaViolationException: [LDAP: error code 65 – Object Class Violation]I don’t understand why, during the import of a user without a ‘firstname’ IDM will not generate a ‘fullname’ or use the supplied ‘fullname’.
    Can anyone help?
    Regards,
    Gavin

    After further testing it turned out that I couldn't create a user without a firstname from the IDM GUI and this in turn was because of the way fullname was generated by the user form.
    I've got the user form changed and now user creation (from the GUI and via bulk import) is working as hoped.

    With the default Adobe Director installation package you
    cannot import 3DS files.
    You need an additional xtra to make that possible.

  • Failure in Model Create Step: com.sap.mw.jco.JCO$Exception: Missing R3NAME=

    Hi,
    I am running NW04sp10 and am trying to connect my WebDynPro to my R/3 backend app server - am running through the FlightChecking example using DevStudio 2.0.10.
    Have successfully created my meta + app data JCo's, they test and ping OK from the Content Manager.  SLD is fine, connecting happily to the NW and R/3 boxes.  One is message server, one central instance.
    When the 'create model' wizard tries to build the java proxies though, it comes back with this:
    [Fatal]:     com.sap.mw.jco.JCO$Exception: Missing R3NAME=... or ASHOST=... in connect_param in RfcOpenEx
    Can anyone help?
    Cheers guys,
    Andy

    Hi Wael,
    I'm using the tutorial 'Handling Transactions with BAPIs in Web Dynpro' [part of SAP Online Help].
    The BAPI does work in se37, it's just a standard SAP delivered BAPI, and I've tried a few different ones to make sure it wasn't a BAPI specific problem.
    In the content admin I've navigated through the local/FlightChecking/Applications/FlightCheckingComp and then used the wizard to add the 2 JCOs [I've kept the default names for now after your previous advice]
    The data is like this:
    WD_MODELDATA_DEST:
    Name                  WD_MODELDATA_DEST
    Client                800
    J2EE Cluster Name     NW1 on chippy
    USER                  USER1
    Password              <password>
    Application Server    nero
    System ID             00
    WD_RFC_METADATA_DEST:
    Name                  WD_RFC_MODELDATA_DEST
    Client                020
    J2EE Cluster Name     NW1 on chippy
    USER                  USER1
    Password              <password>
    Application Server    chippy
    System name           NW1
    Logon Group           PUBLIC
    My landscape here is of 2 servers:
    'Nero'    SAP r/3 4.7 Application Server System ID ACI
    'Chippy'  SAP WebAS640 NW04 System ID NW1 ABAP+J2EE stack
    The JCOs 'test' and 'ping' successfully.  My WD_RFC_METADATA_DEST connection is to a message server, the WD_MODEL_DEST is to a central instance.
    Here's the full log from the create model wizard [I used a random BAPI for testing, BAPI_GET_PAYSLIP, so don't worry about that]:
    [Warning]:     Creating a connection with Metamodel language <en_GB> failed.  Continuing with language <EN>

    [Info]:     Creating Model Relation: Bapi_Get_Payslip_Input:Output:Bapi_Get_Payslip_Output
    So it seems to actually be able to retrieve the metadata for the BAPIs, but not to make the relevant JCo's.  I've not gone on and completed the tutorial, assuming it won't work until I can sort out the above 'fatal' error.
    Thanks again for all of your good advice.
    Cheers,

  • Error in uploading BDC Models (Server name missing from URL in Property wcfmexURL)

    Hi,
    We are using multiple Dialogue Instances in DUET Enterprise.
    Problem: Before we did the Reverse Proxy Configuration for App Servers, Our BDC Models got imported in SharePoint Successfully (Correct WSS Setup and STS Urls) but After doing the Reverse Proxy Configurations, when we regenerated the BDC Models, apparently Server Name is missing from URL of the Propoerty "wcfmexurl".
    Below is the Error Text:
    [ERROR] The LobSystem (External System) / LobSystemInstance (External System Ins
    tance) Property with Name 'WcfMexDocumentUrl' has an invalid value 'https/sap/bc

    Failed to import model: UserRoles

    Hi Holger,
    Thanks a lot!
    This Error is gone after implementing the Note. Now the generated BDC Models have the correct URL for wcfmexURL property.
    now we have the Following Error:
    [ERROR] Error loading URL 'https://sapbwX.srv.XXX.com/sap/bc/srt/wsdl/bndg_92
    38C550B825080AE1000000AC1F18FD/soap12/wsdl11/allinone/ws_policy/document?sap-cli
    ent=XXX'. This normally happens when URL does not point to a valid discovery doc
    ument, service description, or XSD schema.
        Error was encountered at or just before Line: '48' and Position: '20'.
    Failed to import model: Account
    For this Error, our SharePoint Administrator is checking below Steps.
    1.    1) Open “wcfmexDocumentUrl” URL in the browser and copy all SSL certificates (including Root Certificates) to a file. Then import these certificates in the Trust Relationships section. Then try the import of the BDC Models
    2.   
    2) 2) Verifying Your server uses a virtual hostname and all the configuration (e.g. SSL certificate) is done for this virtual hostname. Also the URLs that are created and used in the BDC model are Same virtual hostnames, but not the ones from the physical server.
    3.  3)Re-verify SAML Authentication type and transport security at SAP.
    4) 4) Browse WSDL at SharePoint Server and verify “WSP:Policy”  and in WSDL make sure that it contains an entry:
    <sp:RequestSecurityTokenTemplate>
    <wst:KeyType>http://docs.oasis-open.org/ws-sx/ws-trust/200512/PublicKey</wst:KeyType>
    <wst:TokenType>http://docs.oasis-open.org/wss/oasis-wss-saml-token-profile-1.1#SAMLV1.1</wst:TokenType>
    </sp:RequestSecurityTokenTemplate>
    I will update the Results after these checks!
    Thanks,

  • Missing R3NAME=... or ASHOST=... in connect_param in RfcOpenEx

    Hi Experts,
    when opening the QueryDesigner i get the following error message after providing logon-data:
    "Missing R3NAME=... or ASHOST=... in connect_param in RfcOpenEx"
    Query Designer does not start after that. Any idea?

    I checked the mentioned services file with a colleague. Both are the same, but he can open BEx and I can not.
    It's just one of many BW systems that does not work. I am thinking about reinstalling SAP GUI.

  • Error: Missing Component

    Hi,
    I'm doing the cross component navigation from the DC A to DC B. I imported DC A into the DC B as "Used WDP Components" and embedded the view of DC A. Build and deployed and everything works fine.
    Then i shut down my PC and launch my NWDS, at WDP Used Component which i inserted DC B, it's now having the <Error: Missing Component>. I'm sure i didnt change anything since then.
    When i try to "Edit Component Usage" and choose the DCA again. An error prompted as below:
    Plgin name: Web Dynpro Project Browser

    How to solve it? Thanks.

    hi
    Remove the DC A from used DCs build and add again to DC B. If not check out DC A, add the Public part again, check in, activate, resync and then add DC A as used DC to DC B. It must work. Hope it helps.

    By running through few posts on SDN a probable solution for this was proposed as: blank the "designtimeWsdlUrl" properties of the model in NWDS and re-deploy the application
    Any help on this would be great.
    Regards,
    Shailesh

    Dear Shailesh,
    Did you try to check the blank the "designtimeWsdlUrl" properties of the model in NWDS and re-deploy the application? please try to check and test.
    Also try to import fresh in new DC and check whether it is working or not.
    Best Regards

  • Import error with MPEG-2 files: Brorsoft Video Converter to Apple Prores.

    Hi,
    The Brorsoft Video Converter software gives me an 'import error' message when I attempt to import files from a folder on my desktop. That folder contains many mpg files (MPEG-2 Video, AC3). Those files in the folder on my desktop came from a Sony video camera.
    I need to convert those mpg files to Apple Prores 422 HQ so I can then edit them in Apple Final Cut Pro X.
    But when I go to import those mpg files into the Brorsoft Video Converter software, it comes up with a message saying: 'import error', indicating that the Brorsoft Video Converter software does not understand the type of file.
    I am on Mac OS X Version 10.6.8.
    I've emailed Brorsoft support but I don't think English is their first language – they've emailed back to me asking for clarification of the problem. And I need the problem fixed as I have to edit this video for someone that has many waiting customers.
    Could something have changed in the files when I copied them from the video camera to the desktop?
    Thanks in advance.
    Cheers,
    Paul

    Hi Tom,
    Thanks for your prompt reply. I was using a friend's video camera – I've just texted him for the exact model of Sony video camera. I didn't yet have the Brorsoft Video Converter software when I had to give the video camera back to my friend. So, I copied the files off the video camera to my desktop.
    It records onto an internal hard drive. And yes you're right, I don't need to go HQ. I also tried plain Apple Pro Res. That didn't work either. It comes up with 'Import error' message, so it seems like it just doesn't understand the file type.
    When I go 'Get Info' on one of the files off the camera, it tells me it is an 'MPEG-2 video, AC3' file.
    I'll try and get MPEG Streamclip like you suggested and see if that works.
    Thanks again.
    Cheers,
    Paul

  • New Business Method in EJB not available in Webdynpro Model

    Hi,
    I am using EJBs for Business Logic in my webdynpro java application. I have added a new Business Method in one of the session bean. But I am not able to see the new method in webdynpro model. I am following the below procedure -
    1. Select the Session bean.
    2. Add New Business Method. It automatically adds the method in Remote and Local Interface.
    3. Implement thie new method.
    4. Build EJB project
    5. Add it to EAR
    6. Build EAR Project
    7. Deploy EAR Project
    After following above steps, when I am trying to create a model in my webdynpro project, it does not reflect the changes (context returned by new business method).
    Can any one help me on this ?
    Thanks in advance,
    Gaurav

    The issue is resolved. This is the case where methods in beans returns collections. For such scenario, relations have to be created manually, it does not come automatically. For details refer the blog at below link --
