Local Dictionary Simple Data Types - RFC Model

Hi,
can somebody help out with this error message:
com.sap.tc.webdynpro.services.exceptions.WDTypeNotFoundException: type com.global.wdschulung3.types.String could not be loaded: com.sap.dictionary.runtime.DdException:
     at com.sap.tc.webdynpro.services.datatypes.core.DataTypeBroker.getSimpleType(DataTypeBroker.java:242)
     at com.sap.tc.webdynpro.services.datatypes.core.DataTypeBroker.getDataType(DataTypeBroker.java:205)
is it something to do with the JCO Connection?
I have checked in the WebDynpro Content Admin - and I don't get a green or red Status Symbol - in fact it's just grey - and buttons for "create JCO Connection" ars disabled
thanx for help,
matthias

Hi Bhavik,
thanks for the links - now i configured the sld supplier in visual admin tool and it looks good. Connection test is successful.
Now I was also able to create the JCO Connection in webdynpro content administrator for wd_model_dest and wd_metadata_dest - looks good, and I get a green icon.
Unfortunately testing the jco-connection still fails... I get this error message:
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM  TYPE=B MSHOST=x1t GROUP=SPACE R3NAME=X1T MSSERV=sapmsX1T PCS=1 <b>ERROR       service '?' unknown TIME </b>       Mon Sep 12 14:24:20 2005 RELEASE     640 COMPONENT   NI (network interface) VERSION     37 RC          -3 COUNTER     1
Somebody experienced this before?
thanx once more,

  • Problem with central build of Simple Date Type with Enumeration

    Dear gurus,
    I hope I'm posting this in the correct forum. Please advise if I'm in the wrong forum.
    I have a Web Dynpro DC in which I've created a simple data type with enumeration.  It is used for binding to a radio box. The data type is called DownloadType; the enumeration contains two vales: current and archive. To allow me to access the enumeration values, I turn on the "Generate a class representation of the enumeration" in the data type builder.
    I then reference the enumeration values with code like:
    if (downloadType.equals (DownloadType._CURRENT))
        yada yada yada
    This works fine when building locally and deploying directly. But when the DC is built by CBS (or doing a "Development Component->Build..." in NW Dev Studio), the build fails, stating that the DownloadType._CURRENT symbol cannot be resolved.
    For example:
    C:yadayadayada.java:227: cannot resolve symbol
    symbol  : variable _CURRENT
    location: class yadayadayada.DownloadType
                    equals(DownloadType._CURRENT))  {
    Apparently the central builder is not smart enough to handle the "Generate a class representation" flag.
    Is this a known problem? Are there any workarounds?
    Thanks in advance for any help you can provide.

    P.S. Environment: 2004s

    Hi Kelly,
    works for me using SP10, what SP are you on?
    There's a line in the DC log that says:
         [ddgen] [Info]    Generating datatypes/com/x/x/x/MyEnum.java
    and the java compiler includes the matching path for compilation:

  • Dynamic Drop Down creation using simple data types

    Hi all,
    I have got a requirement in which i have to create an iView which is going to have 6 drop down values and with in that 1 value is going to have sub values which needs to get displayed in the similar drop down fashion.
    I have created a simple data type having enumeration of the 6 values and linked the same to iView with drop down by key which is working successfully. And for the purpose of sub values i have created a similar simple data type with two values and linked the same with a value attribute.
    Well, can any one tell me the further process to proceed ?
    Thanks in advance ...
    Vipin

    Vipin,
    There are quite some steps to achieve what you need. Since you have both your DropDownByKey elements defined and bound to context elements, it may make sense to keep the Second DropDownByKey element invisible and make it visible only when user selects a specified key from first DropDownByKey. To achieve this, follow these steps.
    1. Create an action with a parameter "key" of type string.
    2. Bind this action with onSelect event of your First DropDownByKey UI Element.
    3. Do mapping of parameter "key" in your wdDoModifyView with following code.
      if (firstTime)
             final IWDDropDownByKey dk = (IWDDropDownByKey)view.getElement("DropDownByKey1");
               // Replace DropDownByKey1 with id of your DropDownByKey Element.
             dk.mappingOfOnSelect().addSourceMapping("key", "key");
    4. Create a context attribute of type WDVisibility say "DDVisible" and bind to "visible" property of your second DropDownByKey.
    5. Set DDVisible to NONE in wdInit().
    wdContext.currentContextElement().setDDVisible(WDVisibility.NONE); 
    6. In onSelect action write this code to make second visible
    if(key.equalsIgnoreCase("Two")){
         //Replace "Two" with your required value.
             wdContext.currentContextElement().setDDVisible(WDVisibility.VISIBLE);
           else{
                wdContext.currentContextElement().setDDVisible(WDVisibility.NONE); 
    This should give the desired results.
    Hope this helps.
    Vishwas.

  • Simple Data Type in CAF of SAP NetWeaver DevStudio 7.1 SP3

    Hallo
    Anybody knows about the use of Enumeration for simple Data Type in CAF of SAP NetWeaver DevStudio 7.1 SP3?
    I've defined an attribute "status" for the Entity "Project" with the following values
    0: NEW;
    1: ACTIVE;
    -1: INACTIVE. 
    As you see the data type is short.
    In the program I want to use the following code:
    Project myProject = new Project();
    myProject.setStatus(Status.NEW)
    But I found it out, it is inpossible to to use Status.NEW.
    On the other side I read the article of https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/085098ea-0c01-0010-12a8-80ac838bec85. This article is again not updated with the version 7.1 SP 3.
    I cannot understand about the whole changes. In the previous release we can define a DDIC type and use it as Simple Data type and in the new Release we just use the XSD-Facet to define an enumeration, but the problem is: we can not reference it in the program. I don't see any advantage.  And I tried to find out how I can define the attibute using DDIC type. I didn't get it.
    Thanks for any Hints!
    Kind Regards!

  • Issues in Simple Data Type - Float

    Hi SDN,
    I have created a simple data type of float and assigned to a context attribute. I have mentioned that  the minimum and maximum inclusive value for the float as 0.1 and 29.9. This is assigned to a field aaa. When the page loads for the first time, there appears 0 by default and if I dont edit the field and try saving, it doesnt throw any error message. It accepts the value which was very strange to me. But if I edit the value and put as 0.0, it throws error message saying, the acceptable value for the field is between 0.1 and 29.9.
    What should I do to resolve this issue? Also Can I make the field empty instead of a zero appearing the field?
    Regards,
    Ganesh N

    Hello Ganesh,
    Whatever the value you have provided only that values are allowed in that input field. if the value is 0 or 0.0 you can validate that attribute and throw an error message that "The Value should not be 0".

    Hello,
    I have no definitive idea as to why you are losing the dataypes, though I suspect it has to do with setting the Design Rules under the Tools option.
    The suggestion I want to make is that you generate the DDL from Erwin and and import this and save, all data types should save, they have for me. Also Have found the DDL import to be the most reliable along with importing from Oracle Designer and Oracle database data dictionaries.
    If you have logical objects you want to transfer over then I would advise export Erwin to Oracle Designer and import to SQL Data Modeler.
    If you go through the threads on this forum you are no alone in finding issues with Erwin import.
    Hope that helps.

  • Local Currency - Translation Date Type

    Hi:
    We are on ECC 6.0 with New GL.
    I wanted to check if we can change the Translation Date Type for 1st local currency (10) from Translation date to document date? There are three options in this field - Posting date, document date and translation date. But when we maintain it (under additional local currencies for a company code), local currency has this grey out and comes default to translation date. Not sure where it is defined that local currency can be translated only based on translation date.
    However for 2nd and 3rd currencies this field is open and allow to choose any date type.
    Please advise.
    Thanks,
    Rahul

    Hello Rahul,
    For the local currency, it is hard-coded in the system to
    choose the translation date as the transalation date (type 3). If you
    change this translation date when you enter a document, the system will
    use this new date. However, if you don't change this, the system will
    always use the posting date as translation date for the local currency.
    hope thic clarifies

  • How to reference complex data type when consuming web services in WAS 620?

    In WAS 620, I tried to consume a web service in ABAP. I was successful when the web service returned one or more simple data type. But when the web service is changed to return a complex data type (eg. a structure with 3 elements), the call to the web service did not return anything.

  • AppleScript Call Soap Data types

    I am using AppleScript to issue SOAP requests via built-in the 'call soap' function. The server to which I am connecting uses both simple and complex data types. It's pretty straight forward issuing the basic parameters for simple data types, but if the remote method requires a complex data type, such as a double set of parameters, I can't see how to get it done.
    Anyone have any experience sending SOAP requests with AppleScript that involved complex data types, which include multiple parameters, rather than just simple flat parameter lists?

    Hi,
    not exactly sure what you mean by placeholder data types?
    Surely it would be better to evaluate off a sample employee/departments or predefined database schema if you want to see what the UI / design process is like?
    The design process is very smooth and elegant in JDev 11g if you use the business components from tables wizard in the model and then design pages.

  • GG data type limitation

    Hi experts,
    Source database having below data types , Can you please confirm is there any restrictions in GoldenGate to replicate the below data type data? is the below data types are supported or not supported , please confirm. DB version 11.2.0.2 , OS : Oracle exadata machine , OGG 11.2
    TIMESTAMP(6) WITH LOCAL TIME ZONE
    UROWID
    UNDEFINED
    NVARCHAR2
    RAW
    ROWID

    Hi
    About UNDEFINED data type, do you know what kind of object does it belong to?
    I had the same question but when i queried the database dictionary UNDEFINED data type columns were columns of views with "INVALID" status.
    If this is your case you may prefer to ignore this data type.
    About ROWID columns i have the same concern as you, by now i have experimented with an initial load with 2 databases 11.2.0.3 with identical structure (datafiles, tablespaces), using GoldenGate 11.2.1 and had no problem, the ROWID data type colums loaded correctly.
    I'll continue investigating and if you find out something any feedback would be apreciated.

  • Why need message type when u create data type...

    why need message type when u create data type...

    Hi,
    A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:
    ·        More than one message interface can use the same message type. For example, an asynchronous outbound message interface and an asynchronous inbound message interface can reference the same message type because the request message does not need to be mapped.
    ·        When defining a message mapping you can directly reference message types to map messages from an outbound interface to messages from a receiver interface.
    For technical reasons, a data type is not sufficient to describe the instance of a message. In XML schema, data types are defined as abstract types that are not yet fixed to an element. You can only describe an instance of a message when you have specified a data type as an element type. Therefore, a message type defines the root element of a message.
    A message type does not define the direction of the message exchange, in other words, whether it is a request or a response. In exceptional cases you can use the same message type for both the request and the response message.
    A message type has the following characteristics:
    ·        It comprises exactly one data type, which determines the content of the message to be transferred.
    ·        It is identified by a name and an XML namespace. The name (together with the namespace) of a message type is located in the uppermost tag of the message to be exchanged. This is an element tag.
    You have defined a message type GreetingRes that references a simple data type of type xsd:string. The XML namespace of the message type is http://sap.com/xi/myExample. The corresponding payload might look like this:
    <?xml version="1.0" encoding="utf-8" ?>
    <ns1:GreetingRes xmlns:ns1="http://sap.com/xi/myExample"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
       Hello Mrs. Miller
    </ns1:GreetingRes>
    You can specify how a message type is used in more detail in the description
    hope this will help you.
    regards

  • Accessing data from an abstract data type

    I've been trying to find a way to split up a comma in delimited string PL/SQL, and the following article has helped me do that:
    http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:8861471892664
    Basically, the solution calls for creating a simple data type which looks like this:
    create or replace type myTableType as table of
    numberThis will hold the parsed data, which is populated by calling the str2tbl function. But the article doesn't explain how to access the data inside this table once it's been populated.
    For example, I create the type myTableType and the function str2tbl, and run this query:
    SQL> select str2tbl('4,2,3,4') from dual;
    STR2TBL('4,2,3,4')
    MYTABLETYPE(4, 2, 3, 4)The function returns a table of type myTableType, but I have no idea how access or index the data. I want to be able to access the 4, the 2, the 3, or the 4 of the result that is returned in the above example. Here's what I've tried:
    SQL> select temp(1) from (select str2tbl('4,2,3,4') as temp from dual);
    select temp(1) from (select str2tbl('4,2,3,4') as temp from dual)
    ERROR at line 1:
    ORA-00904: "TEMP": invalid identifierI get the invalid identifier error on pretty much any attempt to get to the data. This seems to be something that's easy to do but I just can't figure it out. Any help would be appreciated, thanks!

  • Converting Resource(Dictionary Simple Type) to Binary Format.

    Hello Experts,
    In my Web Dynpro Application,
    I have a View Context attribute called "FileResource" of type Resource(Dictionary Simple Type) which is bound to the FileUpload UIElement of View.
    When im running the application I am able to Upload the file in my view context attribute successfully,
    Now I need to pass it to the RFC as an Import Parameter which is declared as type "RAW-Uninterpreted Sequence of bytes",
    kindly guide me how to convert the value of the view context attribute "FileResource" of type Resource(Dictionary Simple Type) into BINARY format, so that i can pass it to the RFC as an import parameter.

  • How to use two RFC models in one Data Source for a Interactive Form UI Elem

    Hi
    I want to use two RFC models (two Function Modules from a SAP Backend system) in one context node of a View Controller in order to pass it as the data source to a Interactive Form UI element. Can I use the data binding mechanism directly or have I to copy the data into a Value Node within the view controller.
    Thanks for helping
    René Morel
    SAP (Schweiz) AG

    Rene,
    You can create a local context node in component controller and copy the data from both the RFC's to this node, then bind it to the view controller. Then you can make this view context node as the datasource of the interactive form.

    Anand
