WebDynpro ABAP : Error when calling ME23N with URL

Hi all,
I have some problem with my WDA. I have an ALV in web dynpro and it displays Document number for Purchase Order.
When a user clicks on it, we call SAP WEBGUI using ITS and I create dynamically URL to display the document.
But I can't set the PO number when I call the ME23N while i passed the PO number in parameter of my URL.
My URL has this content : http://xxxxxxx/sap/bc/gui/sap/its/webgui/?sap-client=&~transaction=ME23N&MEPO_TOPLINE-EBELN=xxxxx
But the Po display isn't the same. I don't found any solutions for this problem
Anybody has an idea ?
Thanks in advance for your feedback.
Regards
Ludovic Bento

Hello,
I found the correct way to open ME23N in WebDynpro:
*Create URL
    CONCATENATE 'http://' host ':' port
                '/sap/bc/gui/sap/its/webgui/?sap-client=&~transaction='
                'ME23N' '&~OKCODE=MECHOB&%20MEPO_SELECT-EBELN=' lv_ebeln
                '&%20MEPO_SELECT-BSTYP_F=X&%20~OKCODE=MEOK'
                INTO url.

  • Abap error when entering PO with a different currency

    We are a Mexican company so all our prices and po are made in pesos.
    Today one of our salespersons entered a PO in US Dollars and when he try to save it in VA01 the following error text came up:
    Error execution time:   SAPSQL_INVALID_FIELDNAME
    Exception:  CX_SY_DYNAMIC_OSQL_SEMANTICS
    Text: One of the field names in the SELECT clause was not reconized
    The current ABAP program "SAPLV61Z" had to be terminated because one of the statements could not be executed
    Sadly he did not send me the rest of the message so I will go now to find out if he still gets the error to add it here.
    Thanks in advance.

    Check any of the following notes whether it could be of helpful to you

  • Error when calling method with a return of double in j2me

    hello all,
    i have following problem with a j2me program:
    if i call a method with a return of double, then i get following error
    message:
    ERROR: floating-point constants should not appear
    Error preverifying class test.hallo
    what i'm doing wrong
    thanks in regard
    ----------------example----------------------------
    double yourValue(int y, int m, int d)
    double v = 0.10;
    v = 3.39 y m *d
    return v;
    public void startApp()
    int td;
    int y =2;
    int m =2;
    int d =2;
    td = yourValue(y,m,d);
    return(td);

    It's true for MIDP 1.0.
    But you can always use implementation of the float
    point arithmetic which was written by independent
    developers. For example see J2ME section of my
    homepage http://henson.newmail.ru
    anyway, double is reserved word in java, the way you wrote the source code in your example neither the preverifier nor the compiler will recognize that you intend to use your own types for double and float. maybe with Double or Float it would be different ...
    further question: you declare a void function, in the body, however, you try to return some value. something wrong with this function??

  • Error when calling a Webservice's public method in Forms10g

    Hi,
    I'm getting the following error when calling a webservice's public method, i'm using Forms10g 10.1.2.3
    java.rmi.RemoteException; nested exception is: HTTP transport error javax.xml.soap.SOAPException
    java.security.PrivilegedActionException javax.xml.soap.SOAPException
    Message send failed javax.net.ssl.SSLException SSL handshake failed X509CertChI have added the Jar containing the client proxy in both Classpaths(system variable and default.env), the jar has been made with jdk 1.4
    I also have tested the client proxy from jDeveloper and it's working there, but in Forms i'm getting this error.
    I guess my problem might be that i'm calling a webservice that is secured since the url starts with https
    what should i do to fix this ??
    Regards
    Carlos

    I understand, so i have a doubt, why the webservice works on jDeveloper ??Not just JDeveloper even soapUI and Neatbeans have a way of working without a client certificate installed.
    I do not know how they achieve it. I know that they work without a client DC.
    Cheers,
    PS: See this http://stackoverflow.com/questions/8887434/webservices-ssl-https, it offers a clue.
    The java programs run unhindered when one-way authentication is being used. These products ship with a digital certificate that is in the path of most popular CAs.
    Corollary, if the Web Server is configured for mutual authentication then you need to install and configure the client certificate in the tools.

  • 401 Unauthorized Error When calling a SharePoint REST web service from SharePoint 2013 Workflow

    We have our Workflow Manger installed on the same server as our SharePoint 2013 WFE development environment. When creating a SharePoint 2013 Workflow all Calls to a SharePoint 2013 REST web service results in a 401 Unauthorized error.
    As an example I created a simple workflow that should return a JSON result. The REST Url returns the results in the browser without error.
    Set Variable:webServiceUrl to https://<hostnamedsitecollection>/_vti_bin/client.svc/web/lists/getbytitle('ISR%20Approvers')/Items?$select=Title&$filter=Title%20eq%20%27General%27
    then Build{...} Dictionary (Output to Variable:requestHeaders)
    then Call [%Variable:webServiceUrl%] HTTP web service with request (ResponseContent to Variable:responseContent |ResponseHeaders to responseHeaders | ResponseStatusCode to Variable:responseCode)
    The RequestHeader is set to the requestHeaders variable though the web service call properties
    then Log Variable:responseCode to the workflow history list
    After manually running the workflow in SharePoint on a list item in the ISR Approvers list it Logs "Unauthorized" in the Workflow History Log. It does this with every SharePoint REST web service call that I have tried through the workflow.
    It doesn't have anything to do with the Workflow Manger being installed on the same machine as the SharePoint WFE does it?
    Thank You for any insight

    Hi,
    According to your post, my understanding is that you had 401 Unauthorized Error when calling a SharePoint REST web service from SharePoint 2013 Workflow.
    Please make sure you use the ‘Call HTTP Web Service’ correctly.
    You can enter the URL into the brower to check whether it is correctly.
    You need to
    create the Request header requestHeaders
    using a Dictionary:
    Accept : application/json;odata=verbose
    Content-Type : application/json;odata=verbose
    To associate the
    requestHeaders variable, select the Call action
    property, set the RequestHeaders property to
    requestHeaders.
    Please refer to the following articles:
    Working with Web Services in SharePoint 2013 Workflows using SharePoint Designer 2013
    Calling the SharePoint 2013 Rest API from a SharePoint Designer
    Workflow
    In addtion, you need to make sure you install the workflow manager correctly.

  • Error when extracting data with extractor 2lis_04_matnr - NEED HELP ASAP !!

    Hi experts!
    Got an error when extracting data with extractor 2lis_04_matnr.
    System says (short dump):
    DUMP TEXT START----
    Runtime error:    CONNE_IMPORT_WRONG_COMP_TYPE
    Exception:   CX_SY_IMPORT_MISMATCH_ERROR
    Error when attempting to import object "MC04P_0MAT_TAB".
    The current ABAP program "SAPLMCEX" had to be terminated because one of the statements could not be executed. This is probably due to an error in the ABAP program. When attempting to import data, it was discovered that the data type of the stored data was not the same as that specified in the program.
    An exception occurred. This exception is dealt with in more detail below. The exception, which is assigned to the class 'CX_SY_IMPORT_MISMATCH_ERROR', was neither caught nor passed along using a RAISING clause, in the procedure  "MCEX_BW_LO_API" "(FUNCTION)".                                                                             
    Since the caller of the procedure could not have expected this exception      
    to occur, the running program was terminated.                                
    The reason for the exception is:  When importing the object "MC04P_0MAT_TAB", the component no. 5 in the dataset has a different type from the corresponding component of the target object in the program "SAPLMCEX". <b>The data type is "D" in the dataset, but "C" in the program.</b>
    DUMP TEXT END----
    Please, can someone explain me how to solve it? 
    Really need help ASAP!

  • ORA-03115 error when calling a Stored Procedure

    Hi All,
    I'm in the process of porting a Pro/C app from NT to Linux. I've installed 8.1.5 on our Linux box and patched it up to 8.1.5.02.
    It all kind of works ok, except that I'm sometimes getting ORA-03115 errors when the app calls a stored procedure. The call in question looks like this:
    EXEC SQL BEGIN DECLARE SECTION;
    VARCHAR resprows[50][3998];
    int numret = 0;
    int numrows= 50;
    int done= 0;
    unsigned long resp_id = 0;
    EXEC SQL END DECLARE SECTION;
    EXEC SQL AT DB_NAME EXECUTE
    BEGIN pkg_something.getdata(
    :resp_id, /* IN */
    :numrows, /* IN */
    :done, /* OUT */
    :resprows, /* OUT */
    :numret /* OUT */
    END;
    END-EXEC;
    The stored procedure basically uses the resp_id value to select rows from a table;
    in each row there is a VARCHAR2(4000) column which it copies into the hostarray resprows.
    There may be anything from 1 to numrows returned from the SP.
    Initially, the resprows rows were defined to be size [4000]. Unfortunately, this caused ORA-02005 errors - I then changed the size to [3998], which seemed to fix the 02005's (although I'm unclear as to the reasons why).
    Now I'm getting the 03115 errors when calling the SP. The oracle manual is not very helpful on what this error means.
    This all works chipper on NT.
    Any ideas?
    Thanks in advance,
    Nigel.
    PS: The database the app is talking to is still hosted on NT.

    Marcel,
    JDeveloper will not run out of the box with JDK 1.4. There is a help topic 'Configuring Support for JDK 1.4.0.01 in JDeveloper' that gives you some information.
    But you also need to verify the compatability of all the frameworks you use with JKD 1.4, including BC4J, MVC and UIX. E.g. the classes12.jar we normally use for a JHeadstart application only works with JKD 1.2/1.3.
    Having found out which versions of the frameworks you need, the next step is to validate whether the JHeadstart runtime classes will work with these versions. We have no experience ourself in this respect.
    If it is an option for you, you might consider to downgrade to JKD 1.3.

    1) If for example, there are 50,000 idocs that are being sent and the first 1000 contains an error, will it still process the 49,000 idocs left through RFC client?
    2) what are the possible errors of an idoc which causes the RFC client to be down (having the error above)? is it the format of the idoc? or the idoc_type itself?
    3) another instance would be, if they are resending the idocs again, the RFC will be up eventually and we'll be able to receive the idocs. what are the causes for this?
    4) are there any ways to track these idocs (which contains the error) in BODI or in SAP?
    5) what are the alternative ways of processing the idocs that contains an error?

    I think there is a misspelling in your IDOC type (in header of IDOC probably)
    or the IDOC type does not exist on your SAP system
    you call function IDOCTYPE_READ_COMPLETE remotely on SAP server and this falls into error with exception 1 (OBJECT_UNKNOWN)

  • JAX-WS client error when calling web method

    My JAX-WS client is getting the following error when calling a web method:
    Exception in thread "main" javax.xml.ws.WebServiceException:
    No Content-type in the header!
    I'm using Eclipse as my development environment. I use the CXF facet to generate a WSDL from Java code. I then use the New -> Web Service Client to generate client side code from the WSDL.
    The following fully describes my environment:
    Windows XP
    JDK 1.6.0_22
    Java EE 6
    Eclipse Helios
    Apache CXF 2.3.0 (runtime)
    Tomcat 6.0
    I have found several post on the net that describe this problem and a solution for JBoss, but I have been unable to find anything that addresses this error on Tomcat.
    I can provide source code if needed. The app is a simple Hello World web service. I'm using it to try and get familiar with developing web services with all the components listed above.
    Thanks

    Hi Anders,
    The resolution of the crossdomain problem is not to store an cross-domain-policy file at the [SAP] webservice side; but instead it needs to be done at the (every...) webservice client. In case the client is an IIS based webapplication (and thus the ultimate end-users are accessing it via their browser), this is not such an issue. It there is sufficient to put an crossdomain.xml policy file in the IIS main virtual root of your 'client' .net webapplication (c:\inetpub\wwwroot). It also can be required or at least helpful to put a clientaccesspolicy.xml file; both at the main virtual root and in the virtual root of the specific webapplication
    In case of SharePoint application, the crossdomain.xml file must be stored in the WSS virtual root of that site; c:\inetpub\wwwroot\wss\virtualdirectories\<your SharePoint webapp>
    Best regards, William.

  • IGS error (: Error When Calling Up IGS (ListenerRfc: unknown error))

    Hi,
      We have recently upgraded to NW04S.
      Most of our BW reports( SAP delivered or custom, web template or not ) work fine with the IGS, while some reports don't, We receive a message from the Enterprise Portal ( Error When Calling Up IGS (ListenerRfc: unknown error)). No other details are available
      We have checked and found out the related web templates are actually activates properly. From the same business content, we find some repports work and some don't, all however use web template.
      Has anybody expoerienced the same? Please help.
       Thanks

    Hi AHP,
       1> BW_IGS_ADMIN when executed showed me some charts with some statictics and status etc. However as mentioned the other report BW_IGS_CHART_TEST just shows me a blank screen.
        2> SM59 connection test for the IGS RFC  IGS_RFC_DEST is successful
        3> Ping on the Gateway Host( for the RFS dest) works fine as well.
        4> Also as I mentioned earlier, some of the reports using web teamplate works fine where some are not.
        5> when I do the RFC trace  ( since I get an "Error When Calling Up IGS (ListenerRfc: unknown error) ) via ST01 for the query , in the BI sysatem, I get an error 'Prog:CL_IGS_CHART==================CPRow:'.
       Please let me know how do I proceed further.
    Thanks

  • Error when calling up IGS(listenerrfc: unknown error)

    Hello,
    We have integrated IGS 640.2 running on os windows 2003 64 bit(BW 3.5) .When i call the IGS chart from the EP portal i am getting the following error messge
    Error when calling up IGS(listenerrfc: unknown error)
    When i run the report GRAPHICS_IGS_ADMIN i am getting a blank screen.
    This is in the case of production server.
    I am getting the graph when i run report GRAPHICS_IGS_ADMIN in my BW quality server ( with same version IGS 640.2 os windows 2003 32 bit).
    I have followed the below stpes for re-constructionin BW prod:
    Followed the Snote 458731
    1. Checked the Rfc destination 'GFW_ITS_RFC_DEST' amd 'IGS_RFC_DEST'
    2. I can see the monitoring page when i run http://IGSHOST:LISTENERHTTPPORT
    3. Program id and gateway is properly maintained
    4. It is not generating any dumps when i set the dump status to  "dump_on"
    but in BW quality - dump file is getting generated
    I can't switch on trace because it requires resatrt of teh server which is not possible in production.
    I can see service called SAP IGS in BW qualitybut it is missing BW production.
    Apart from that evrything looks similar in both quality and production server.
    Can anyone advice me on how to fix this issue.
    Appreciate your response.
    Thanks in advance.

    Check the following Note : 454042
    In rz20 you can find the IGS as the Internet Graphics Server in the monitor set SAP CCMS Monitors for Optional Components.
    When you double-click on this entry a hierarchy with performance values should be displayed. If no hierarchy is displayed, even though the IGS is running, call transaction se38 and execute the program graphics_igs_admin. Choose Environment  ® Switch on CCMS to activate the IGS display in rz20.
