Question about Implement EHP4...

Hi,
I went to the following path -
service.sap.com/swdc and choose "My Companys Application Components" -
SAP ERP SAP ERP ENHANCE PACKAGE -
EHP4 FOR SAP ERP 6.0 / NW7.01.
What is the meaning of "ERP 6.0 / NW7.01"?
Does it mean that NW 7.01 can go straight to EHP4.
I am getting confused with EHP2 for NW 7.00, which is the most current fro NW 7.00.
This EHP4 is strictely for ERP only. Correct?
Please clarify.
Regards,
SC

EHP4 for ERP contains EHP1 for Netweaver (701) and is based on that.
EHP5 for ERP contains EHP2 for Netweaver (702) and is based on that.
Those dependencies are fixed.
You can, however, install EHPs on Netweaver systems alone but not on ERP systems.

  • Question about implementation of a webservice

    Hi
    I have successful implemented a webservice call in my webdnypro application. But I am not sure if I have done this the right way
    Scenario: I have a view which displays data from a business partner. These data can be accessed over a webservice. The webservice requires a parameter with the id of the bussiness partner.
    My solution: I have implemented a method in the component controller (*comp.java).
    public void getBusinessPartnerInfo( java.lang.String businessPartnerCode )  {
        //@@begin getBusinessPartnerInfo()
           service = new BPService();
           Request_GetBPInfo request = new Request_GetBPInfo(service);
           GetBPInfo getBPInfo = new GetBPInfo(service);
           getBPInfo.setCardCode(businessPartnerCode);
           request.setGetBPInfo(getBPInfo);
           try {
                request.execute();
           } catch(WDWSModelExecuteException ex) {
           wdContext.nodeRequest_GetBPInfo().bind(request);
        //@@end
    and I invoke this method from the wdInit method of the same controller.
    public void wdDoInit()
        //@@begin wdDoInit()
           this.getBusinessPartnerInfo("c1000");
        //@@end
    Therefor the data is available when the view is loaded. But I am asking myself if this is the right way to do that? Wouldn't it be better to call this webservice invocation from the init method of the view?
    Additionally I do not know at the moment how to access the environment of the portal for information. E.g. the business partner code c1000 is hard coded at the moment. I would like to read this code from the environment, e.g. the portal. Over which API can I access data from the portal or better say from the ume (where i can map a field to the business partner code)?
    Thanks for your answers,
    Thierry

    Hi,
    As far as your first question is concerned you can access the controller method from the view linked with the controller as follows:
    wdThis.wdGet<Contoller Name>Controller().yourMethod();
    I have no idea that you can store generic information such as BP code specific to a user in EP. Lets see.
    thanks & regards,
    Manoj

  • Question about implementing a clock using a Timer object

    Hello all, I'm not sure if this is the correct forum to post this question but I think so, as it regards a Swing component. I want to add a timer (a clock that starts at 0:00 and keeps track of how long the app is running) to a frame. I am just curious if using a Timer is the proper way to keep track of time, and just repaint() the clock object every second? (or more frequently if desired)... or is there a better way to do this? Thanks in advance for any comments/feedback/help!
    Brian

    Hello,
    Timer is not accurate. You can use Timer to display your component repeteadly, and System.currentTimeMillis() at each call to deduce the elapsed time.

  • Question about implement the transaction in EJB

    Dear Sir
    I try to do some transaction work in EJB,I builded 6 bean blow
    OrderMgr(session bean) control Order(CMP Entity Bean)
    Istock(session bean) control Item(CMP Entity Bean)
    DeliveryMgr(session bean) control delivery(CMP Entity Bean)
    I try to implement the transaction in session bean OrderMgr Like
    public void submitOrder(int id) {
    Try
    Istock.dosomething
    Delivery.dosomething
    Bookorder.dosomething
    catch (Exception ex) {
    sessionContext.setRollbackOnly();
    But not Rollback not work
    Then I change Session Bean OrderMgr to BMT,write the code blow, but rollback still not work
    sessionContext getUserTransaction().beging();
    Try{
    Istock.dosomething
    Delivery.dosomething
    Bookorder.dosomething
    sessionContext.getUserTransaction().commit();
    catch (Exception ex) {
    sessionContext. rollback();
    Could anyone tellme what's wrong with me code?
    &#12288;&#12288;

    If you want to rollback work done by these methods, than you have to make sure that they don't start a new transaction. i.e. they should use tx attribute "required" or "mandatory".
    Istock.dosomething
    Delivery.dosomething
    Bookorder.dosomething

  • Using the RK4 VI, had a question about implementation

    Here's a link to the system I'm approximating:http://i.imgur.com/EXnswBm.png
    The way it's going to be used, it will use current values to calculate values that will be important in the next iteration of a while loop. The values passed into it via the X0 input will be from the last loop iterate, and the values coming out will be sent into a shift register. The length of each iteration varies according to another VI, so it'll be flipping between 5 and 10 minute cycles.
    My question pertains to that max[] that's in the DE for I1(t).
    Since labview isn't a functional language, I know that whatever I put into the F(X,t) array will be interpreted as a string, and not parsed as a function. Since the max operates on one of the variables, I can't simply apply the max[] operation outside and just leave that space as a number, or a dummy variable.
    So is there any way to do this? Even a case structure wouldn't handle it, because it'd have to be applied for every iteration of RK4, and not just to the VI as a whole

    The fundamental issue is that max() is not a differentiable function so the system of equations is not one which RK would be expected to solve.  Any differential equation solver in LabVIEW or a text-based language will need to do something beyond the normal solving process to deal with the discontinuities created by max().
    If I2 is reasonably well behaved near zero, creating two sets of equations for I2 > 0 and I2 < 0 and switching based on the previous value of I2 might work.  It will be much slower because you will need to stop and start the solution process.
    The RK algorithms are documented in a number of references. It might not be too difficult to program your own with the max() function built in.

    The problem really is that there is no distribution for this Jar.... The classes are found in several places, but where they'd be on a Mac, I don't know... They don't come with Java, they come with the browser.
    Of course, one solution I've seen is to use reflection to get a JSObject and it's methods... it's a bit more code, but it doesn't require having the actual classes to build.
    What I did to get my copy of these classes is to find them in the Netscape 4.7 installation's files and pull the netscape.javascript classes out to make a little Jar that I use for development purposes. It's just the classes needed to compile them... I would post that Jar here except that I'm really unsure of any legal issues regarding doing that...
    But if you can get a copy of Netscape 4.7... You could do a search for files containing "JSObject" and you'd find a jar or zip file there.

  • Question about Kurts comments discussing the seperation of AIA & CDP - Test Lab Guide: Deploying an AD CS Two-Tier PKI Hierarchy - Kurt L Hudson MSFT

    Question about the sentence in bold. What is the meaning behind this comment?
    How would you separate the role of the AIA and CDP from a CA subordinate server? I can see where I add a CES and CEP server which has those as well, but I don't completely understand his comment. Because in this second step, (http://technet.microsoft.com/en-us/library/tlg-key-based-renewal.aspx)
    he shows how to implement CES and CEP.
    This is from the guide located at: http://technet.microsoft.com/library/hh831348.aspx
    Step 3: Configure APP1 to distribute certificates and CRLs
    In the extensions of the root CA, it was stated that the CRL from the root CA would be available via http://www.contoso.com/pki. Currently, there is not a PKI virtual directory on APP1, so one must be created.
    In a production environment, you would typically separate the issuing CA role from the role of hosting the AIA and CDP.
    However, this lab combines both in order to reduce the number of resources needed to complete the lab.
    Thanks,
    James

    My concern is, they have a 2-3k base of xp systems, over this year they are migrating them to Windows 7. During this time they will also be upgrading hardware for the existing windows 7 machines. The turnover of certificates are going to be high, which
    from what I've read here, it worries me.
    http://blogs.technet.com/b/askds/archive/2009/06/24/implementing-an-ocsp-responder-part-i-introducing-ocsp.aspx
    The application then can go to those locations to download the CRL. There are, however, some potential issues with this scenario. CRLs over time can get rather large
    depending on the number of certificates issued and revoked. If CRLs grow to a large size, and many clients have to download CRLs, this can have a negative impact on network performance. More importantly, by
    default Windows clients will timeout after 15 seconds while trying to download a CRL. Additionally,
    CRLs have information about every currently valid certificate that has been revoked, which is an excessive amount of data given the fact that an application may only need the revocation status for a few certificates. So,
    aside from downloading the CRL, the application or the OS has to parse the CRL and find a match for the serial number of the certificate that has been revoked.
    With the above limitations, which mostly revolve around scalability, it is clear that there are some drawbacks to using CRLs. Hence, the introduction of Online Certificate
    Status Protocol (OCSP). OCSP reduces the overhead associated with CRLs. There are server/client components to OCSP: The OCSP responder, which is the server component, and the OCSP Client. The OCSP Responder accepts status
    requests from OCSP Clients. When the OCSP Responder receives the request from the client it then needs to determine the status of the certificate using the serial number presented by the client. First the OCSP Responder determines if it has any cached responses
    for the same request. If it does, it can then send that response to the client. If there is no cached response, the OCSP Responder then checks to see if it has the CRL issued by the CA cached locally on the OCSP. If it does, it can check the revocation status
    locally, and send a response to the client stating whether the certificate is valid or revoked. The response is signed by the OCSP Signing Certificate that is selected during installation. If the OCSP does not have the CRL cached locally, the OCSP Responder
    can retrieve the CRL from the CDP locations listed in the certificate. The OCSP Responder then can parse the CRL to determine the revocation status, and send the appropriate response to the client.

  • PL/SQL web service: question about stub

    hello,
    I'm currently learning how to work with PL/SQL Web Services.
    I have a question about stubs. The point is, I can deploy a web service to the OC4J server and it works. It also works when I create a stub following the WSDL I made with creating the PL/SQL web service. If I go to the endpoint in my webbrowser, the functionality is the same, with or without using a stub.
    My question is: what is the function of the stub?

    A stub is leveraged by a client application to communicate with a corresponding server side object (in this case, the web service implementation). If you think back to CORBA or RMI applications they follow a similar pattern.
    In the case of a web service you would use the stub to write a client application that could invoke the methods of the remote service and return the responses as java data types. The methods the stub class offers are the same as the methods of the web service interface. It's a common way for providing RPC like functionality.

  • Questions about CIN tax procedure choice and pricing schemas

    Hi all,
    I have to implement SAP on a Indian company and I'm verifying all particularity about this country (in particular tax procedures and the great number of differents tax conditions used).
    I have two questions about tax procedures and pricing schemas. Every feedback about thse points will be appreciated.
    a) To choose tax procedure TAXINN or TAXINJ which are the elements that I have to consider?
         I have read lot of documentation about CIN implementation and Iu2019m oriented to choose TAXINN schema, but If possible I  would  to understand better which are on behalf of one choice or another.
    b) To define pricing schemas for India, after check with local users and using examples of documents (in particular tax invoice) actually produced, I have understood that taxes have to be applied on amount defined starting from price list, minus discounts recognized to customer plus surcharges eventually to bill (packing, transport,  etc.).
    Itu2019s correct for any type of taxes that tax amount is calculated on u201Cnet valueu201D defined at item level or there are exceptions to this rule?
    Thanks in advance
    Gianpaolo

    hi,
    this is to inform you that,
    a) About point 1 I know the difference between the 2 tax procedures (conditions or formulas). I also have read in others post in the FORUM that TAXINN is preferable. So I would to understand which are the advantages to choose instead TAXINJ. There are particular reasons or it'a only an alternative customizing setting?
    a.a. for give for posting the link : plese give me the advantages of TAXINJ and TAXINN
    CIN - TAXINN and TAXINJ
    b) About point 2, to define which value has to be used as base amount to calculate taxes isn't a choice, but is defined depending by fiscal requirement of the country, in this case India fiscal requirement. I know that, as Lakshmipathi
    write as answer on my question, exception could be, but it was important for me to understand if I have understood correctly the sequence of the pricing condition in the schema in "normal" situation.
    b.b. you can create your own pricing procedure for this and go ahead.
    hope this clears your issue.

  • Question about the programming of a legend

    Hello everybody,
    I have a question about the programming of a waveform's legend. I
    already asked here in this forum about the legend programming (03)
    months ago.
    I went satisfied but I ve just noticed that this code
    (See Code old_legend_test.llb with main.vi as main function) operates a
    little different from my expectances.
    Therefore I have a new question and I want to know if it
    is possible by labview programming to plot and show, on a waveform
    chart, a signal with activ plot superior to zero (0) without to be
    obliged to plot and show a signal with activ plot equal to zero (0) or
    inferior to the desired activ plot.
    I give you an example
    of what I m meaning. I have by example 4 signals (Signal 0, 1, 2 and 3)
    and each signal corresponds respectively to a channel (Chan1, Chan2,
    Chan3, Chan4). I want to control the legend (activ plot, plot name and
    plot color) programmatically. Is it possible with labview to plot signal
    1 or 2 or 3 or (1, 3) or (2,3) or (1,2,3) or other possible combination
    without to active the signal with the corresponding activ plot zero
    (0)?
    Let see the labview attached data
    (new_legend_test.llb with main.vi as main function). When I try to
    control the input selected values again I get them back but I don't
    understand why they have no effect on the legend of my waveform chart.
    Could somebody explain me what I m doing wrong or show me how to get a
    correct legend with desired plots? Thank by advance for your assistance.
    N.B.
    The
    both attached data are saved with labview 2009.

    Hi
    princejack,
    Thanks for
    posting on National Instruments forum.
    The behavior
    you have is completely normal. You can control the number of row displayed in
    the legend and this rows are linked to the data you send to your graph. Thus,
    if you have 3 arrays of data, let say chan1, chan2 and chan3, you can choose
    which data you want to display in your graph using the property node (Active
    plot and visible). But for the legend as you send 3 plots there is an array of
    the plot name [chan1, chan2, chan3] and you can display 0, 1, 2 or 3 rows of
    this array but you cannot control the order in this array! So, to be able to
    change this array you have to only send data you need to you graph. I'm not
    sure my explanations are clear so I have implemented a simple example doing
    that.

  • Question about Logon ticket with user mapping at BI-JAVA environment

    We're implementing BI 7.0 including BI Java and SAP EP for end user
    access.
    I have two question about SSO method when we're using BI Java.
    I know we can simply configure SSO logon ticket with BI-Java(EP
    included) and BI-ABAP through BI template installer and we already
    succeeded in that case.
    But the problem is we want to change it to user mapping SSO method for
    some our internal reason.
    After we configure user mapping SSO, we've got SSO failed error when we
    call BI-Java stuff like BEx Web Application iView.
    After many testing implemented, we found SSO Logon ticket with user
    mapping (using SAP reference system). It seems working now.
    But our question is "Is it no problem when we use SSO logon ticket with
    user mapping?" Is there any restriction or issue?
    One more question is we can ONLY use user base mapping when reference
    system used. How can we assign BI-ABAP users to EP Group?

    Using an SAP Reference system is allright. But if the reason u r going for this is because of different usernames in EP and BI, why dont you go for user mapping.
    Anyways, on restriction of reference syetms is that you can have ONLY ONE reference system defined in portal. In you case you can only have the BI system defined.
    Hope this helps!!

  • A question about compatiblilty of JDBC

    Hi, there,
    I have a question about JDBC 3.0 in JDK1.4.1.
    We build a .jar using JDK1.4.1 and this .jar file
    provides JDBC 3.0 interface.
    I then tried to call the interface under JDK1.3.1
    but it keeps asking me about the getParameterMetaData()
    in PreparedStatement.
    (The error message like this:
    Exception in thread "main" java.lang.NoClassDefFoundError: java/sql/ParameterMetaData dbmaker.sql.JdbcOdbcConnection.prepareStatement(JdbcOdbcConnection.java:257)
    I did implement the getParameterMetaData() method,
    but I didn't call this method in my testing program.
    It's quite strange since when JDK1.2 was release,
    we implemented the getBlob() method in
    ResultSet class and there's no problem when we
    use JDK1.1 run time to call this ResultSet object.
    Could any one tell me why? Is this caused by a
    compatibility problem between JDK1.4 and the
    older versions of JDK?

    Hi, there,
    Let me outline the condition by examples so that maybe you can help me. PLEASE! Could somebody tell us what's wrong?
    - CASE 1:
    In JDK1.2, we implemented a new method getBlob which returns the type of Blob (this is done according to JDBC 2.0 specification.) in ResultSet class. We can use the .jar compiled by jdk1.2 in jdk1.1 environment.
    e.g. We make a xyz.jar by jdk1.2 and the xyz.jar includes new method getBlob in ReaultSet class. Then, one java application including ResultSet class CAN run under jdk1.1 with xyz.jar, if the method ResultSet.getBlob() is not called.
    - CASE 2:
    BUT, the following case which is the same as in the above condition will fail in jdk1.3 environment.
    In JDK 1.4, we implemented a new method getParameterMetaData() which returns the type of ParameterMetaData. (BTW, this is done according to JDBC 3.0 specification.) in PreparedStatement class. We CANNOT use the .jar compiled by jdk1.4 in jdk1.3 environment.
    e.g. We make a ttt.jar by jdk1.4 and ttt.jar includes the new method getParameterMetaData() in PreparedStatement class. Then, one java application including PreparedStatement class CANNOT be run under jdk1.3 with ttt.jar, even when the method PreparedStatement.getParameterMetaData() is not called.

  • EBS 12.1.3: a few questions about cloning

    Hi,
    We have EBS 12.1.3 on AIX 7.1.
    A few questions about cloning from shared application tier environment to non-shared application tier environment. We have been following "Cloning Oracle Applications Release 12 with Rapid Clone [ID 406982.1]"
    Source environment (shared app tier):
    - Two active application nodes and LB
    - One active database and one passive database setup with Oracle Data Guard.
    - SSL termination at the load balancer
    - PCP implemented
    Target environment (non-shared app tier):
    - One active application node
    - One active database node
    - No SSL
    - No PCP
    After the cloning was completed we noticed the following problems in the target system:
    1) Home page cannot be accessed as application tier $CONTEXT_FILE still contains "https" and ssl termination settings.
    Workaround:
    Modify (with text editor) Application Tier $CONTEXT_FILE as follows.
    <webentryurlprotocol oa_var="s_webentryurlprotocol" customized="yes">http</webentryurlprotocol>
    <sslterminator oa_var="s_enable_sslterminator">#</sslterminator>
    <login_page oa_var="s_login_page" customized="yes">http://myhost.mydomain.com:8000/OA_HTML/AppsLogin</login_page>
    <externURL oa_var="s_external_url" customized="yes">http://myhost.mydomain.com:8000</externURL>
    Run AutoConfig and start application tier.
    Is there a better and supported solution for this?
    2) Concurrent managers do not work correctly as they have still old node names (used in PCP in the source system). Workaround used:
    1. Logon to EBS web GUI and remove all nodes from all concurrent managers.
    2. Shutdown application tier. Verify that all concurrent managers have been shutdown. If not, kill the processes manually
    3. As apps user run cmclean.sql
    4. Restart application tier
    Is there a better solution for this?
    3) Database changes from ARCHIVELOG mode to nonarchivelog mode in the target system. Is there anyway to prevent this?
    4) Also, we would like to perform a full clone (app + db tiers) from production without shutting down the application. Is this possible? What would be the best documents to describe this? In Production, we have Oracle Data Guard setup with physical standby as per "Oracle Tech Note: Business Continuity for Oracle E-Business Release 12 Using Oracle 11g Physical Standby Database [ID 1070033.1]". This can be used when performing a hot clone for the database, right? What about the application tier? Steps described in 406982.1 include running AutoConfig in which application tier should be down. Does the application need to be down when running "Maintain Snapshot Information"?
    5) One final question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. E.g. https://myhost.mydomain.com:5501/em gives "Page cannot be displayed". This was working correctly last week. In Firefox, the same link is working fine. Any ideas how to fix this?
    Thanks for your answers in advance.

    3) Database changes from ARCHIVELOG mode to nonarchivelog mode in the target system. Is there anyway to prevent this?By default, Rapid Clone will create the target database in noarchivelog mode.
    4) Also, we would like to perform a full clone (app + db tiers) from production without shutting down the application. Is this possible? What would be the best documents to describe this? In Production, we have Oracle Data Guard setup with physical standby as per "Oracle Tech Note: Business Continuity for Oracle E-Business Release 12 Using Oracle 11g Physical Standby Database [ID 1070033.1]". This can be used when performing a hot clone for the database, right? Correct.
    What about the application tier? Steps described in 406982.1 include running AutoConfig in which application tier should be down. Does the application need to be down when running "Maintain Snapshot Information"?You can copy the application tier node files while the application is up. And, you do not need to shutdown the application to run "Maintain Snapshot Information".
    5) One final question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. E.g. https://myhost.mydomain.com:5501/em gives "Page cannot be displayed". This was working correctly last week. In Firefox, the same link is working fine. Any ideas how to fix this?
    If it is working from one browser, then it should not be an EM issue. Have you tried from a different client and see if this works? Have you changed any setting in your IE browser? Please make sure you add the EM URL to the trusted sites list.
    Thanks,
    Hussein

  • A question about Job schdueling in cluster

    hi all
    I have a weblogic cluster and want to use the build-in commonj support to do some scheduling work.the pdf version document "Timer and Work Manager API (CommonJ) Programmer's Guide" has something like this on page 7,"The Timer Listener class must be pesent in the server system classpath" .does it mean that I should not put it in web-inf/classes?instead, I should jar it and put the jar somewhere inside wls_home/server/lib or ext ?
    thanks a lot :-]

    hi mchellap
    here is another question about timers in the cluster,
    1) I implemented a serializable timerlistener which I want to make it cluster aware
    2) put the JNDI items "timer/MyTimer" in web.xml which is to commonj.timers.TimerManager
    3) I created a datasource on cluster in console with the tables created in db
    after the cluster is started,the job is to print out the "new Date()" in console every 40 second,and it worked very well
    I am expecting something in the db table,but there is nothing,not even a exception ,anything wrong here?
    thanks a lot
