Consumption of data model created using Screen Scraping

Dear All,
I have created a GW Data Model for recording a standard SAP transaction and subsequently created its GW Consumption Model in SAP Netweaver Gateway.This will return a REST service.This REST service supports 'CRUD'
(CREATE,READ,UPDATE.DELETE) operations as per the documentation .While using this REST service I am facing two
problems.
Case 1:
I created a GW Comsumption Model by recording transaction 'TZ60' for READ operation,created QUERY operation
and 'TZ90' for UPDATE operation. I can use the READ operation successfully in Dot Net Application but how can I use
the UPDATE operation in Dot Net Application ?
Case 2:
Can wev create Screen Scraping Data Model for complex transactions involving Multiple Screens/Tabstrips and ALVs.
Please reply to this thread as soon as possible.Thankyou.

  • Can SQL Dev Data Modeler be used to reverse engineer Windchill PDMLink

    Does anyone know if SQL Developer Data Modeler be used to reverse engineer Windchill PDMLink Oracle database? I need to get the DDL and ERDs from Windchill PDMLink.
    Can SQL Developer Data Modeler be used to reverse engineer object oriented Oracle databases?

    SQL Developer Data Modeler be used to reverse engineer Windchill PDMLink Oracle databaseprobably you mean Windchill PDMLink tables in Oracle database - yes, it's possible to get the structure of tables.
    Can SQL Developer Data Modeler be used to reverse engineer object oriented Oracle databases?It's not clear for me - you can reverse engineer definition of object and collection types, definitions of tables and views including those that use object and collection types in their definition.
    You can try it.

  • Problem saving data model when using Oracle DB Pivot feature

    I have problem saving a data model - SQL Query that uses the Oracle DB PIVOT feature?
    When I hit save, nothing happends.... have also tried "save as" - nothing is saved
    No error message is shown.
    Is Oracle DB PIVOT not supported by OBIEE?
    The SQL that is causing the problem is this one:
    SELECT * FROM
    SELECT field_name as field,
    CASE
    WHEN col_1 = 'A' THEN 'Name 1'
    WHEN col_1 like 'B_%' THEN 'Name 2'
    END
    as gastype,
    energy
    FROM table_1
    WHERE code = 'K'
    AND trunc(DAYTIME,'YYYY') = trunc(to_date('2012-01-01 00:00:00','YYYY-MM-DD HH24:MI:SS'), 'YYYY')
    AND (col_1 in ('A') or col_1 like 'B_%')
    PIVOT (sum(energy) for (gastype) in ('Name 1' as Name1, 'Name 2' as Name2))
    order by field
    We are using OBIEE 11.1.1.6.7 (Win 2008R2) against Oracle DB 11.2.0.3

    Just a wild guess .. Have you done dbsetup after installing IAS and said you are going to said databases ?

  • SQL Developer Data Modeling-- Creating Image

    Hello,
    you can create sequences and triggers in Oracle physical model - you can find triggers under table node (physical model).
    However it'll be better for you to do development of triggers in SQL Developer. After development of triggers is over you can put your triggers in data modeling physical model.

  • Data modeling , creating dimention

    hi ,
    i have a relational DB in Oracle 11g ,i am going to make a data warehouse using OWB , i want to do data modeling , which tools i can use for data modeling ?

    Analytics Workspace Manager is the administration tool of the OLAP Server (MOLAP) from the Oracle Database.
    You can build an Olap cube with it.
    http://www.oracle.com/technology/obe/11gr1_db/otn_all_db11gr1.html#olap
    But you can also do it with OWB. And you can do with OWB all what you need to build a datawarehouse.
    Try to go through the tutorials. It's the best way to learn.
    If you have problem to define measure and fact (which is a big subject), the best way is that you buy this book :
    http://www.amazon.com/Data-Warehouse-Toolkit-Complete-Dimensional/dp/0471200247/ref=pd_sim_b_3
    You will find on it all what you want with a clear language (It's the bible for modelling)

  • Import option is not showing the Data Source created using ODBC

    Hi all,
    I'm new to OBIEE, just installed OBIEE 10g in my system with the help of some reply from this Forum (thanks to Kalyan for this).
    Now when I tried to create new rpd, the Import option is not showing the Data source I have created. I have created new Datasource in the SystemDSN tab of the ODBC Administrator window,I have tried this by creating the Datasource in the UserDNS tab as well.
    Mine is Windows 7 Ultimate. The new data source which I have created through the ODBC Administrator window is to connect to SQL 2008 (I'm trying to get some table from SQL 2008 database), I don't have Oracle data base.
    While creating the Data source ODBC Administrator is showing only two drives (SQL Server and SQL Server Native Client 10.0 ) , so I have created the Data source using the SQL Server Native Client 10.0 drive.
    Can some one help me to understand the issue and to solve it.
    Thanks,

  • SQL Developer Data Modeler-  Creating super/subtype relationship

    The User's Guide does not tell you how to create super/subtype relationship.
    To create super/subtype relationship in a logical model, you must already have the two candidate entities; one to be the supertype, the other subtype.
    - on the logical model diagram, right click the candidate subtype and select Properties
    - on the Entity Properties dialog box, select the candidate supertype from the Super Entity drop-down list, then OK
    Depending on whether you enable or disable the Box-in-box Presentation on your logical diagram, the subtype would be shown inside or outside its supertype entity, respectively

    Hi Peter,
    When I examine an XML file for a relation converted from version 2.0, the XML elements "nameOnSource" and "nameOnTarget" are missing in the converted 3.0 EA1 versionthey are not loaded during "open" of older design. If you define them they will go into XML file.

  • Data Modeling - Creating a multipling factor for a year

    We have a need on a report to adjust the result by a percent based on the year.  i.e. if the value is 100 and it is in year 2007 we might add 1% making the end result 101.  But if the value is 100 and it is in year 2006 we might want to subtract 2% making the end result 98.
    My first thought was to create this percent as an attribute on 0CALYEAR, but it is not possible to place attributes on time charateristics.  Does anyone have any suggestions for me to consider on how we might model this?
    Thanks,
    Chris

    Hello Chris very simple suggestion for you copy from 'value' field 2 new value  fields in query one for 2006 and filter this with calyear 2006 and multiply with .98 and one for 2007 and filter with calyear 2007 and multiply with 1.01. Show them in columns.
    Don't worry about records for 2006 the 'value 2007' will be 0 and records for 2007 'value 2007' will be 0 
    Simple one

  • Table Data Validation, Created using ViewLink

    Hi All,
    I have two ViewObject SwitchFundFromVO and SwicthFundToVO, these two are linked with ViewLink. Now In the JSPX page i have two table. One is using SwitchFundFromVO and another one using SwitchFundToVO.
    Table: SwitchFundFromVO
    1.) This a pre populated table.
    2.) Its a single selection based row, whenever user clicked one row from this table, he/she can enter value at the SwicthFundToVO table below and can enter any number of rows.
    Use Case:
    So let say, if SwitchFundFromVO has 2 pre populated rows, and user select the first row to switch his fund from. then he goes to SwitchFundToVO table and enter 2 rows where he/she wants to switch the fund.
    And again user select the 2nd row from the SwitchFundFromVo and goes to SwitchFundToVO and enters two rows for this also.
    So now 1 rows of SwitchFundFromVO table is linked with 2 rows of SwitchFundToVO table.
    I have two columns in SwitchFundToVO, one is FundName and another is Percentage, now i want to check that those two rows user added for each of the SwitchFundFromVO should match with 100%. After user clicked Submit Button.
    Hope I am clear here, I am trying this with managed bean, but didnt get how to go about this kind of Validation.
    Thanks,
    Neeraj

    Thanks Arun,
    Will try as u suggested, but still i believe it wont calculate the percentage block by itself, we have to calculate percentage column and throw and error message if the sum is not equal to 100%.
    Anyways i will try and let you know.
    Thanks,
    Neeraj Halder

  • 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 use an existing data model using Business Components in OEPE

    I am a beginner in ADF. I am working on a project with an existing data model that uses Business Components (EO, VO and AM). I know that OEPE does not handle the creation of BC, so if I want to modify them, I will have to do that in JDev. That's fine.
    OEPE can create pages with drag and drop like in JDev. In my eclipse ADF projects, I would like to use the existing BC, to be able to use the bindings with ADF Faces. So far I have nothing in the Data Controls tab.
    How to import the BC into the Data Controls tab?
    JDev 11.1.1.6
    WLS 10.3.6
    Eclipse Kepler

    We currently don't support DataControls based on the ADF BC technology. We will consider such support if there is a strong interest in that use case.
    Independent of the IDE's you use, there are ways to expose services based on ADF BC that can then be consumed by the view layer. A Google search will point you to some of the approaches.
    HTH. Thanks for your interest in OEPE.

  • PowerPivot removed table replicated into the data model on refresh

    Hey
    I am facing the following problem which is absolutely persistent and annoying in nature. I am using a data model created with PowerPivot with connections to three different SQL servers and 25 tables. The bug is that every time I refresh my data, a table
    that was initially added to the data model (and later removed) is replicated in equivalent number of tables that use this connection, which is currently around 12 tables, so I get 12 duplicates of the same unnecessary table on every refresh, named with the
    name of the schema on the SQL server that is followed by a running number. Removing these from the data model on every refresh simply takes too much time on a daily basis. The additional undesired table which is created is what is defined in the SQL query
    of the connection string of this connection.
    I tried to solve this problem by zipping the Excel file and modifying this SQL statement present in the connection string in the connections.xml file in a way that it would not return anything, but this always leads into a corrupted workbook.
    After encountering this I have managed to avoid this problem by making sure that the initial table I'm adding to the data model will remain in the model, but I really don't want to rebuild this current model. Is there any fix for this issue without
    rebuilding the data model?
    Thanks for all the help in advance!

    I am using 64-bit Office 2013 with the recent SP1 upgrade and the included PowerPivot plug-in on a Windows 8.1 machine.
    I always create the connection by using "From SQL server" then fill in the server and log in details and use a ready SQL statement that I have written by using SQL Server Management Studio to import the initial table. For all the preceding tables
    using the same server and schema, I always select it from existing connections and just paste the SQL queries required for any additional tables to the "Write a query that will specify the data to import", rather than using the table import tool.
    I am not sure if it could have any effect that I've been using the type connection "From SQL server" although the database is really running on Azure (there is a possibility to select From Other sources > Microsoft SQL Azure, but the functionality
    seems the same).
    I don't really understand what I should edit from the existing connections section. Just to clarify, apparently the Connection String parameters can be edited from PowerPivot, but not the Command Text which can be viewed from Excel Data > Connections
    > Properties, but is shown in gray with a message "Some properties cannot be changed because this connection was modified using the PowerPivot add-in."
    In the data model I am using two sets of identical tables, but connected to two different servers that are running a database 1:1 in structure. Initially the problem considered only the other of these, but I accidentally reproduced it by, again, editing
    the SQL query in the table that was initially imported when that connection was created (PowerPivot > Design > Table Properties). Now when refreshing I get tables that are structured as in what the "Connection Text" part of the connection would
    produce, which replicated for the equivalent amount of additional tables using the same connection, so now I'm getting 12 tables (the number of tables using the same connection) each named "*schemaname1* Query", "*schemaname1* Query2",
    "*schemaname1* Query3" "*schemaname2* Query" and so on.
    Personally I can definitely see a pattern here. If there isn't a table matching what has been specified in the "Command Text" that was described when the connection was created, then it for some reason runs this query anyway on every table that
    is using the connection.

  • Oracle BI Publisher no columns loaded from data model

    Hello Guys,
    I use Oracle BI Publisher 11g. Have created a data model by using
    the JDBC thin connection to a 11g database. The creation of the data model
    worked fine using a SQL query. Now in the report creation wizard, I select
    the "guide me" option to see how nice the wizard is.
    The problem comes here, on the second window I should select the columns
    but I only read "no columns available". Why is that?

    Hi Metalray
    For BIP report sample XML data is importent. with sample data you cannot generate the BIP reports.
    Follow the below steps, you can achieve your expected BIP output
    After crating data set in the data medel save the data model then click on
    --get XML output option on right side of the top-corner.
    -- then selet no. for the nuber of rows to return dropdown option,
    --then click on Run. Then save the sample data by clicking on Save as sample data option.
    --then it will take you to the data model page, now again save the data model
    --and use it for creating the reports.
    Now you were able to see the available columns in the the second window of guide me option
    please mark if it helps you..

  • Does SQL Developer Data Modeler fit-in??

    Hi Everyone,
    Wish you happy new year 2011.
    Does SQL Developer Data Modeler support conceptual, logical and physical in our modeling or only logical and physical?
    We all use Erwin for modeling. Erwin works without database repository storing models in desktop folders and provide additional reporting. I find some place SQL Developer Data Modeler talked about repository need.
    Does SQL Developer Data Modeler store the models in local/network folders instead of Database server?
    What are the functions need database based repository to work with SQL Developer Data Modeler?
    We are thinking of using SQL Developer Data Modeler for our conceptual, Logical, and data dictionary need. Will it help in our need?
    Do we need to face any surprises on using SQL Developer Data Modeler for our need?
    Thanks in sharing your experience and helping me out.
    RI

    1) Do we need to have Oracle database at back end to work with SQL Developer Data Modeler?No, Data Modeler use Oracle database only if you create reporting repository.
    Data Modeler is free, you need database license only if you want to log service request
    2) Will SQL Developer Data Modeler create any tables (as backend repository ) in Oracle database to store Model details? no
    3) Do we need to create reporting schema in backend oracle database to generate reports of SQL Developer Data Modeler's items such as Entity/attributes etc?no, reports can be created out of current loaded design. However having reporting repository will give you additional benefits - history (reports can be generated for every snapshot of your designs there) and multi-user usage, you can create your own reports
    4) Do we to use SQL Developer Data Modeler reverse engineer from DB2, SqlServer, Terra data etc?Data Modeler has full support for Oracle, DB2/390, DB2/UDB(LUW) and MS SQL Server. Reverse engineering from other databases (including Terra Data) is at generic JDBC level - you'll get some and some will be missing (no check constraints for example).
