Hi Rajesh,
I cleared this certification last year. Go through the syllabus mentioned. In our time there were 13 different sections e.g NWDI, EJBs, WD etc which had multiple choice qs and u need to click on the radio button for that.
How to prepare.
Go through the topics and course books mentioned in the syllabus well. U should be clear with all the basics especially EJBs and NWDI, lot many qs asked from these. WedDynpro qs are basically easy.if u dnt have books chk sdn and help site fot the topics.Qs chk your understanding of the content. They come from syllabus but are not direct and multiple choice make it difficult to answer.
How to answer the questions.
Chk every option in case of mutiple choice. Mark only those options which u are full confident and den if more than 50% confident bcoz we heard there were -ve markings although not sure how they calculated marks.
Is any sample test program is there?
There are no sample test program for this.
All D Best for the certification.
Regards
Priyanka

    Intel Core Duo is a 32-bit processor, so the latest Mac OS X version you can install is Mac OS X Snow Leopard -> http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
    You are running Mac OS X 10.6.8, so you are already running the most recent Mac OS X version for your computer.

  • Can we join Ztables with SAP std. tables in SQVI ?

    Dear All,
    Can we join Ztables with SAP std. tables in SQVI ?
    How to use "left outer join" in SQVI ?
    What r the rules/steps to be followed for creating right SQVI/query ?
    Sometimes it gives error / we do not get any output ....
    Pl' give examples.

    hi
    good
    1- Yes
    3-Check this example for SQVI Query.
    It is possible to generate a complete list of purchase document releases with the purchase document number (requisitions and orders), releaser, release date and release time.
    First, create an Infoset using transaction SQ02 directly reading from table CDPOS and create an additional table: CDHDR. If you are releasing purchase requsitions at the item level, it is convenient to create an additional field (PURPS LIKE EBAN-BNFPO) to capture the item number. Once the field is defined add the following code to it:
    PURPS = CDPOS-TABKEY+14(5).
    Once created, make sure to assign your Infoset to the user groups.
    Second, create an SAP Query (SQ00) or QuickViewer (SQVI) based on the Infoset you created previously. Set CDPOS-OBJECTID, PURPS (additional field), CDHDR-USERNAME, CDHDR-UDATE & CDHDR-UTIME, CDPOS-TCODE, CDPOS-VALUE_NEW, and CDPOS-VALUE_OLD as list fields (display screen).
    Set CDPOS-OBJECTCLAS, CDPOS-OBJECTID, CDPOS-TABNAME, CDPOS-FNAME, CDPOS-CHANGIND, CDHDR-USERNAME, CDHDR-UDATE & CDHDR-UTIME as the selection fields (selection screen).
    Finally, execute your query. For filtering purchase requisition releases set:
    Object class='BANF'
    Table Name='EBAN'
    Field Name='FRGKZ'
    Change type='U'
    For filtering purchase order releases set:
    Object class='EINKBELEG'
    Table Name='EKKO'
    Field Name='FRGKE'
    Change type='U'
    Make sure to specify username, dates or purchase document number (object value) in order to reduce run times.

  • 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.

  • Best Practice to start with SAP NetWeaver BI (BW) to become a BI consultant

    Hi there,
    I have one Question. As consultant for SAP NetWeaver Portal (Development/Java), I would like to start with SAP NetWeaver BI (System Configuration, Customizing and Development with ABAP/ABAP OO) through e-learning and/or with (e)books.
    A system for making practice is available.
    Can someone give me a helpful guide how to start and become a BI Consultant for system administration and development within the next 12 months?
    Some Questions I have noticed are:
    1) The system (application) environment of BI (what is integrated in it - e. g. within the portal, there is a storage for unstructured information like documents or virtual rooms for collaboration between departments - and what does it make)
    2) How does development in BI works (development environment, coding, debugging, building, deployment and test) and what is used stronger (ABAP or ABAP OO)? Here, I don't mean how to write ABAP or ABAP OO programs, only the infrastructure from development to transport to a target system
    3) How is a BI system to configure as default after installation?
    4) Good guides (e/books) to learn ABAP and ABAP OO (as far as possible oriented on the practive)
    Of course, these are only a few Question and far from complete. Details and other important points will be appreciated.
    Many thanks,
    Cengiz

    Hi,
    1) The system (application) environment of BI (what is integrated in it - e. g. within the portal, there is a storage for unstructured information like documents or virtual rooms for collaboration between departments - and what does it make)
    Document management from RSA1 transaction of BI helps to attach any unstructured documents at specific level in BI.
    2) How does development in BI works (development environment, coding, debugging, building, deployment and test) and what is used stronger (ABAP or ABAP OO)? Here, I don't mean how to write ABAP or ABAP OO programs, only the infrastructure from development to transport to a target system
    BI has got  a separate tool and GUI to perform all the Extract, Transform and load related activities. ABAP is part of BI but you don't need much extensive ABAP learning. Basic ABAP is sufficient to write routines and extractors.
    3) How is a BI system to configure as default after installation?
    May be a BASIS person can help you out here about the configuration but this is not the job of BI person.
    4) Good guides (e/books) to learn ABAP and ABAP OO (as far as possible oriented on the practive)
    You can search for SAM Series learn ABAP in 24 days book. This book is sufficient to learn the ABAP required for working in BI.
    But except ABAP you will have to completly learn the BI system to work efficiently.

    Durgesh.

  • Problem connectivity of Web Dympro with SAP Netweaver

    Hi guys,
    I've a problem connectivity of Web Dympro with SAP Netweaver
    I installed Sap NW in a machine on the local network with IP 192.168.x.y, and I can connect to it without problems; I can use the portal and implement jobs in Visual Composer.  
    After installing Sap Developer Studio, I connected it successfully to the NW through the menu "Preferences->SAP j2EE engine" selecting the option "SAP J2EE is installed on remote hosts" and inserting IP address of the machine with NW (192.168.x.y) and port 3900.
    Using these parameters the logon works, in fact I can see the tab "J2EE engine".  
    The problem is that when I try to make the deploy, Web Dynpro asks me the SDM password  (that I'm sure I've inserted correctly) but it returns the following error to me:
    Deployment aborted
    Settings
    SDM host : SVR-NW
    SDM port : 50118
    URL to deploy : file:/C:/DOCUME1/Michele/IMPOST1/Temp/temp59548Welcome.ear
    Result
    => deployment aborted : file:/C:/DOCUME1/Michele/IMPOST1/Temp/temp59548Welcome.ear
    Aborted: development component 'Welcome'/'local'/'LOKAL'/'0.2010.09.01.07.31.29':
    Caught exception while checking the login credentials for SAP J2EE Engine. Check whether the SAP J2EE Engine is up and running.

    (message ID: com.sap.sdm.serverext.servertype.inqmy.extern.EngineApplOnlineDeployerImpl.checkLoginCredentials.DMEXC)
    Deployment exception : The deployment of at least one item aborted
    I want to add that  I use Win XP Prof, and I set the same credentials (user "Administrator" and the correct password) I used on the machine where SAP NW is installed.

    Hi Michele,
    There were 2 cases I explained, and the second was the one in case your SDM was blocked. Did you try the first one?
    Anyways, here is something more that you can try to get it working. In case the SDM password is valid, did you log into the portal as the Administrator? If yes, then you must have been asked to change the password. If you did change the password there, login to the remoteGUI using the Master password (abcd1234) and change the password there also to the same password you use for Administrator on the Portal. Now try again.
    In case the above doesnt work, start the configtool.bat from \usr\sap\J2E\JC01\j2ee\configtool and go to secure store. Here define the J2E passwords again (the same new password you gave for the Administrator in the portal), save and restart the server. I think it would work then
    Hope that helps you out!
    Bye,
    Sameer
    P.S - the main thing is that the error you got was Authentication failure using the Administrator username. Thats why you have to make sure that the password for the SDM is the same as what you gave for the Administrator login in the portal. So after you login into the remoteGUI, CHANGE the password to what you have for the Administrator(just like the one in the portal).

  • Best practices of integration with SAP Netweaver

    Hi All,
    I'm totally new to SAP Netweaver but I have a task to integrate our system with SAP ECC (R/3). We are using SAP Netweaver 6.4. The goal of integration is to provide for user list of available modules (Sales and Distribution, Human Resource, Payroll, etc) and when user selected for example Payroll we need to display list of available BAPIs. In general weare able to create Enterprise Web Service for some BAPI and consume it. But the problem is that everytime when administrator changed BAPI process (for example added new field to Business Object) we need to regenerate wsdl and change our client application. Does Netweaver provide some Web Service which can retrieve list of applications, list of BAPI processes and can retrieve meta data of some BAPI? Something like Partner Web Service interface?
    We are looking for best practices of integration with SAP Netweaver. We are trying to develop something like adapter which will be able to pull data into SAP ECC system is there any generic way to develop this adapter?
    Thanks in advance for your help.
    Yura.

    Hi Yura !!
    As far as I know, this is not possible yet. Using SAP Netweaver XI/PI, although it adds value to the webservice scenario exposing BAPI functionality, it also needs to maintain a refreshed version of the BAPI definition in its repository. Depeding the complexity of the change in the BAPI structure, maybe PI may allow you to continue working without changes.
    Maybe a good practice is not to make too much changes to a production BAPI, instead make a review in development environment, and once it is stable, use it in production. Other good practice is to keep older versions of BAPIs and add the changed ones as new versions to have back-compatibility
    Regards,
    Matias.

  • SAP certified professional - ABAP system interfaces with SAP netweaver 7.0

    Hi,
    I have one and half years experience in ABAP. I want to do "SAP CERTIFIED DEVELOPMENT PROFESSIONAL - ABAP SYSTEM INTERFACES WITH SAP NETWEAVER 7.0".
    I am currently in U.S and would like to do the certification here. Whom do I need to contact and what are the documents I need to furnish. Please throw some light on the process.
    Thanks,
    Poonam.

    Dear Poonam,
    the "Professional"-Certification is very very hard - during my last Certifcation Exam, all candidates with the Pro-Exam failed (I was so glad I chose the normal certification...)
    Here's how to book your exam:
    Go to [http://www.sap.com/services/education/certification/index.epx|http://www.sap.com/services/education/certification/index.epx] and follow the instructions ("visit the local SAP Education Web site for the country").
    Figure out the exam code for your certification. Example: For the US, there is a downloadable list (PDF) of exams available, called "list of the available certification exams".
    Schedule the exam according to the rules of your region - here is the link for the US:
