Create a Model

Good Day All,
when I tried to create a model in SAP Netweaver Studio and I got the following error message:
An internal error has ocurred, see error log for more details.
Plugin name: Web Dynpro Model Editor
Plugin ID: com.sap.ide.webdynpro.modeleditor
class: com.sap.ide.webdynpro.modeleditor.ModelEditorCallback
Method: createModel
Message: An error ocurred, see error log for more details.
Exception: java.lang.NullPointerException: null
anyone have any idea what cause that error message?
thanks,

Hi Rami,
It looks like this NPE is coming from the Web Dynpro model plug-in code.
If 'Create Model' was working earlier, then this might be due to metadata corruption. Close the NWDS.
1) Either delete the contents of the metadata folder of your workspace & restart NWDS.
2) Or you can restart NWDS in a fresh workspace.
Please verify that you are providing all the required parameters in the model creation wizard.
If the NWDS installation has gone fine & still the problem persists, this seems to be a bug & you can raise a customer ticket (CSS message on Web Dynpro component)
Kind Regards,
Nitin
PS: If you are using quite old version of NWDS, I would advise you to upgrade to a later version as these very basic things should be working fine.

Issue while creating Data Model in BI Publisher and logging into xmlpserver

Hi All,
We are facing an issue in OBIEE 11.1.1.5.
If we are logging with Non Admin Id (other than weblogic) and select New Data Model, a blank screen is coming. Where as, if we use Admin Id, we are getting screen as usual for creating data model. There were some blogs mentioning to change Priviledges for SOAP access, but that approach is also not working.
Further, we are also not able to open xmlpserver with Non Admin Id.
Any help or pointers would be great.
Regards,

how about pasting the content of your data template here, so that forum members can see what could be the problem.

How to customize Category and Category items list while creating New Model

Hi,
what the most convenient way to customize the Category and Category items list while creating New Model?
This is standard:
Now, what we want to achieve, is to customize this menu, to:
1. Display in the Category window only f.e. two categories:
- EA Diagrams
- BPM Diagrams
2. In the EA Diagrams, we want to have f.e. four copies of City Planning diagram, each of them should have different elements available, f.e. in the first copy, only Architecture Areas shall be made available, in the second one Architecture Areas and Business Functions, in the third on f.e. only Business Functions shall be made available. Additionally, it should behave like a hierarchy ... meaning you can create the second diagram, only as child (related diagram) of the first diagram etc.
I know, excluding the particular diagrams/diagram elements can be configured using the right/profile settings, but how to:
1. Customize the standard New Model menu window
2. Create copies of City Planning Diagrams with different set-ups
3. Set the relationship between diagrams
Is such a configuration change possible?
Thanks a lot for your help!
Regards,
Rafal

Now, what we want to achieve, is to customize this menu, to:
Question #1. Display in the Category window only f.e. two categories:
- EA Diagrams
- BPM Diagrams
Click on Tools => General Options=> Model Creation
Click on Properties => at right of Default category set
Note : Model template does not work as Category. We can't set. An enchancement request has been open to SAP
In the following example I defined a new default (MyNewDefault.mcc). As you can see only BPMN models are available.
To create a new category set with BPMN choice
a) Copy default.mcc in MyNewDefault.mcc file.
    Go to Tools=>General Options=>Model Creation : Select your new category
    Go to Tools=>General Options=>Model Creation : Edit properties and remove all things you does not want keep
or
b) Go to Tools=>General options=>Model Creation : Edit properties and click on Save as button and specify the file name "MyNewDefault".
    Quit the window.
    Select you new category : Go to Tools=>General Options=>Model Creation : "MyNewDefault"
    Edit properties and remove all things you does not want keep.
    Save you new category
Question #2. How to define copies/replicas of existing diagrams
     Wrote an extension
Question #3. How to make sure, particular diagrams can be used (created) only on predefined "levels" and how to set the parent-child relationship, so that PD enforced it directly when creating a new diagram.
     Specify yours conditons in your extension attached to your model
     Example : When the user want create a child diagram : You can display a list of Parent Diagrams to select from.
     You can set in your extension by VBScript parent-child relationship
Question #4 In the EA Diagrams, we want to have f.e. four copies of City Planning diagram, each of them should have different elements available, f.e. in the first copy, only Architecture Areas shall be made available, in the second one Architecture Areas and Business Functions, in the third on f.e. only Business Functions shall be made available.
If I understand well your question. I suggest to take a look in
Repository=>Administration=>Objects Permission Profile
You can specify objects to show, mask, deactivate at model level.
You can specifiy your own metadata.
But I'm not sure you can mask, deactivate functions following diagram selection. It seem to specific.

Program for creating a model is locked by User

Hi Guys,
We have created a process chain to create the Integration Model and to activate the Integration Model using this prg RIMODGEN. So, This prg we have created variants for different location wise. This process chain contains 13 processes For each location, which is running in parallel. Some time we are getting the error message " Program for creating a model is locked by User
Regards

Dear Pullaiah,
Locking happens if there is any overlap of models or duplicate scheduling of jobs with same variant.
See include LCIFIF01
CALL FUNCTION 'ENQUEUE_ECIF_IMOD'
EXPORTING
    mode_cif_imod = 'E'
    modelname      = i_modid
    logsys         = i_logsys
    apoapp         = i_appl
EXCEPTIONS
    foreign_lock   = 1
    system_failure = 2
    OTHERS         = 3.
So this means for you, you get the lockentry if the modelname, logsys and apoapp is the same. So please check again your variants if there is one with the same integrationmodels.
This can be the only reason we you get here this entry in your joblog.
Regards,
Tibor

How to create a Model based on an SQL Server?

Hello,
Can someone please guide me how can I create a Model which takes it's Data from a table in an SQL Server?
Can I make such a Model that will connect directly to a Datasource on the Application Server?

Well Roy,
I was also facing some similar problem, just now got my service displayed in portal. Thanks a lot that you could solve it urself. Anyway, now for using this service from another portal component do the following
1. Add SharingReference value in Deployment Descriptor of the portal app from where u want to access this service
example:
<application-config>
<property name="SharingReference"      value="com.customer.training.MyFirstPortalApp">
</property>
</application-config>
2. Add libraries of the Portal Service (xxxapi.jar)
in your par file u can see one jar file as <servicename>api.jar . extract this to some other location and in the client portal app project add this .jar to its build path.
3. Write code to access the Portal Service
    a. Import package of the Portal Service
    b. Get instance of the Portal Service
    c. Call methods of the Portal Service
example:IPortalRuntimeResources runtimeResources =      PortalRuntime.getRuntimeResources();
IService aService = runtimeResources.getService("com.customer.training.MyFirstPortalApp.MyService");
// OR
IService aService = runtimeResources.getService(IMyService.KEY);
// Cast the Service
IMyService myService = (IMyService)aService;
// call methods of the service
response.write(myService.getWelcomeString(aName));
thats how it should be...

How can I create a model node in SAP Records Management

Product: SAP Records Management
Hi,
I would like to create a model node in a record tree.
I found in the function modul BAPI_RECORD_ADDELEMENT no entry for the creation of a model node. Only the instance and the structure node can create by this function modul.
So, does anyone know a solution to create a model note?
Regards,
Thomas Fanninger

Hi Thomas,
it is not possible with the BAPI due to the piece of coding:
case myElementType.
        when glob_const_elem_type_instance.
          myRecordElement->Type_Set( if_srm_sp_record_element=>type_instance ).
          myRecordInstanceElement ?= myRecordElement.
          loop at element_sp_poid into myElementSpPoidWa.
            mySpPoidWa-id = myElementSpPoidWa-name.
            mySpPoidWa-value = myElementSpPoidWa-value.
            insert mySpPoidWa into table myElementSpPoidTab.
          endloop.
          myElementSpsId = sps_id.
          myElementPoid = myClientService->poid_get_instance( im_rms_id = myRmsId
            im_sps_id = myElementSpsId im_sp_poid = myElementSpPoidTab ).
          myService->check_sp_connection( myElementPoid ).
          myRecordInstanceElement->poid_set( myElementPoid ).
        when glob_const_elem_type_folder.
          myRecordElement->Type_Set( if_srm_sp_record_element=>type_folder ).
        when others.
          perform set_error using '852' return.
          return.
      endcase.
But you can do that by using directly the Records API. How to use this is demonstrated in the report 'SRM_RECORD_API_HOWTO'. Search there for the subroutine 'fillrecordelement'. There a record element for insert is created and its type is set. You can set the type there to 'IF_SRM_SP_RECORD_ELEMENT~TYPE_MODEL'. Of course your POID then may not be an instance POID.
Best regards,
Thomas

Issue while creating a model

Hi,
I am creating an model expression to calculate value at leaf level for one of the member.
my expresssion is like this
type_calcparent = type_postcogs + type_postrev + type_-1
Model is not accepting "type_-1" value and taking type_ and -1 as different values thus giving error saying "type_" value do not exists in the dimension.
Also type_-1 exists in dimension.
Any solution to this problem.
Thanks in advance.
Thanks
Brijesh

Brijesh,
When using dimension values containing characters that have special meaning (calc operators, spaces, etc.) you will need to refer to these dimension values using quoted dimension values. Your calculation need to be written like this
type_calcparent = type_postcogs + type_postrev + 'type_-1'
Note: Most likely the dimension value will be in capitals, since quoted dimension values are used the value needs to be an exact match, so most likely it would need to be
type_calcparent = type_postcogs + type_postrev + 'TYPE_-1'
Best practice is to avoid these kind of dimension values.
Regards,
Frank

Problem in creating DATA Model from SQL SERVER 2008 in BI PUBLISHER

Dear Team,
I connect BI Publisher with SQL SERVER 2008 But On creating Report on BI,when we create data model...dataset,
i select the tables but when i click on RESULT i am geting this error.
error--
[Hyperion][SQLServer JDBC Driver][SQLServer]Invalid object name 'DBNAME.DBO.TABLE'.
please resolve this problem...
Thanks,

Hi David,
The things I said are not a fix for this problem.
If your RCU installation worked, then you do not have to worry about modifying the createfr.sql.
Edit:
I've just tracked the problem. It appears that when using the query builder, BI forgets to add the " sign.
For example:
This query will give the hyperion error.
select     "table"."field"
from     "database.user"."table"
To correct it write it like this:
select     "table"."field"
from     "database"."user"."table"

Error when creating data model - Internal Server Error

When trying to create a new Data Model in BI Publisher (11.1.1), we are getting a “Internal Server Error” message and the page to create data models wont display. We are able to login to BIP with any user, but we cant do anything else… (seems due to a null pointer exception, as shown in this message):

Unable to Create Entity Model from existing oracle database

Hi,
I am using Visual Studio 2013, .net framework 4.5, entity framework 5.0 and oracle 11g database.
Issue Description: I need to develop WCF service to exposing the account information which needs to get the data from 20 oracle tables. Trying to create entity model from existing oracle database. first i tried creating just two tables it
was created but it took more than 30 minutes. then i selected remaining few tables it took more than a days but nothing created just showing spinning the wheel. then i tried with fresh project and selected all the tables but same issue nothing created and
also there is no error. during this process i checked database query monitoring there is a big sql statement collection tables metadata. i don't know what was wrong the query taking too much time to complete the process.
we tried multiple machine and different oracle database all are same issue.
Sql server database -looks good no issues.
Any help/tips/ideas welcome to overcome this issue.

Hi Sakthimp,
Welcome to MSDN forum.
Your issue is out of support range of VS General Question forum which mainly discusses the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Because your issue only occurred with oracle database, moreover Oracle developed the Entity Framework for Oracle itself, I suggest that you can consult your issue on Oracle forum/community:
you will get better solution and support there.

Can't create a model

Hi,
I have an usable SLD server.
Now, I have to configure NDS on my local workstation.
I have changed the windows hosts and services files and inscribed the SLD server as group in my SAP Gui Frontend.
Now, if I want to Create a model in my Webdynpro application, I don't see the message server in the combobox "System" of the register card "Load Balancing".
I know that the SLD is working correctly, but I can't use him.
Can it be a problem, that I have installed the NDS before I have installed the SAP Frontend Gui?
regards,
Dennis

hi,
the NDS doesn't use the SLD for these settings.
you have to enter your message server manually.

How to create a model and JCO connection

Hi all,
The Userid and Password given while creating new model at Singleserver/Load balancing tab should be same as the userid and password given while creating JCO connection. i.e in JCO creation while mapping modeldata to Application data and Metadata to metadata we will give some userid and password.
will those 2 userids and passwords should be same.
the error which i am getting is
com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException: Error connecting using JCO.Client: null
Regards
Padma N

2 userids and passwords need not be same
i got similar problem and this is how i resolved
this is because jco connections are Using SSO and the user who is accessing that webdynpro application is not present in the backend system.
please make sure user is there in the backend system from which you are getting data

Creating a model in pages

Hi Everyone,
I have created a model in Pages composed of text boxes and shapes. I find the that the model formating becomes skewed when the pages file is converted into a word document. I thought I could overcome this by creating the model in Keynote, exporting it as a PDF and then inserting it into the Pages file. The only issue is that I can not resize it accordingly once it is in Pages.
So I have 2 questions:
1. What is the best way of making my proposed model in Pages?
2. How can I ensure that the model is not out of format when converted to a Word file?
Any assistance would be greatly appreciated! Thank you.

study the chapter 13 entitled: *Designing Your Own Document Templates* in the Pages User Guide.
2. How can I ensure that the model is not out of format when converted to a Word file?
The only way is to check that what you designed is correctly converted.
Often it will not, and it is perfectly normal!
To be sure to get a clone, use the original !
