Data Model Layout (crossing lines)

Hi Everybody,
I downloaded the SQL Data Model and doing some modeling. It is doing a good job.
How can I adjust the crossing lines in the diagram. I am not able to bend the relationship lines.
Are there any hidden (undocumented) shortcut KEYS to do that?
Where can I find those defined shortcut KEYS?
Do we have an auto layout option to adjust the Entities and relationships in a page?
Thanks in sharing your experience.

Hi,
you need to switch "Auto route" off and you'll be able to position manually the lines.
Do we have an auto layout option to adjust the Entities and relationships in a page?There is limited "auto layout" functionality in relational model but it's not page oriented.

How to make use of a different data model for a line chart?

I have a datamodel which is a sql query. I have a line chart on my template which is using some "Start Time" field as X-Axis. There is a chance that "Start Time" is null. In such cases the plotted point doesn't appear with x-coordinate. But I can't change the X_Axis field to some other not-null attribute due to business requirement.
I am thinking to create another datamodel which filters all "Start Time"s which are nulls and use that datamodel for the line chart that has "Start Time" as X-axis. But I don't know how to do this as whenever I try to insert a line chart from BIPublisher menu in MS_Word, I am not prompted to select the datamodel.
Can anybody tell me what I am trying is possible? If so how? If not, how do I have "Start Time" as X-axis without hassles?
Thanks,
-Vijay-

Are you able to extract the data based on the new data model in an XML file? If so, in BI publisher desktop, are you able to load the XML data via Add-Ins ->Data -> Load XML Data?
If you have been able to load the data successfully, then you need to Select Chart from the Insert Menu. When you do that, you should be able to see the Data layout on the left side of the chart dialog box. Then you should be able to drag and drop fields as necessary to create the chart. Are you having issues doing this part?
You will not be prompted to select the data model. Hope I haven't misunderstood your question.
Thanks!

SQL Data Modeler adds blank line to UK Constraints

Oracle SQL Developer Data Modeler Version: 2.0.0 Build: 584
I'm migrating my schema designs from Oracle Designer to SQL Developer Data Modeler. When I get to the point of generating SQL files I consistently get an extra blank line added to every unique constraint. My primary key constraints are defined the same way, but they do not have the blank line. See below for an example of the SQL output:
ALTER TABLE ALIAS
ADD CONSTRAINT ALIAS_PK PRIMARY KEY ( ALIAS_NO )
USING INDEX TABLESPACE INDEX1
NOLOGGING
NOSORT
ALTER TABLE ALIAS
ADD CONSTRAINT ALIAS_UK UNIQUE ( ALIAS_NAME )
USING INDEX TABLESPACE INDEX1
NOLOGGING
NOSORT
This blank line causes errors when I execute the SQL script so I have to edit it before using. Did I forget to something or is this a bug?
Thanks,

One data model - different user-defined layouts

I want to develop a report where the user can change
the layout model herself/himself, but can not change the
data model.
The best would be:
Generating a XML-File with Report Runtime and
having an XSL-Stylesheet example report for the
XML-File.
The user should get an "easy to use" tool to
change the given xsl-stylesheet report example (perhaps
possible with MS(C) Word ?)
Has anyone experiences or ideas?
[email protected]

I suggest you make a standard report and let you user make use of runtime customize feature to alter report layout properties. In this case you can not change the layout completely but can do some customization for each user with the same report.
Thanks

Crossed line in SmartForm Layout

Hi All,
There is a requirement in my project, One form should be developed with crossed line.
How we are dividing a square in to two equal Triangles by using a crossed line, Like that I should design in my layout.
How Can I print ?
Advance Thanks to Helpful answers.
Regards,
Suresh

Hi,
Only option I could think of is creating a black and white image with the cross feed line. The image size should be the same as your page size. Then import the bitmap image in Application server using SE78. Then use Background Picture tab in the page options in SMARTFORMS to use the same as background. This would give your page a look of Cross Feed lined page.
Thanks.

Data Modeler - How to move relationship lines?

I can't figure out how to move the relationship lines on the data modeler.
Tried a bunch of things that have worked in all the other modelers I've used, but no luck. Couldn't find anything in the help text about it, either.
Edited by: David Wendelken on Nov 14, 2008 4:07 PM

Hi Jim, David,
AutoRoute (on/off) can be managed at diagram level - use right mouse click on empty space.
In current published release (AutoRoute off) - straight lines (only two connection points) cannot be moved. You need intermediate points (at least one) for better arranging. Points (Elbows ) are created using Ctrl+mouse click.
Connection points also can be moved in next EA release.

2) In options to manage the Table report (Reports -> Manage). Currently I can only remove a heading (like Descriptions Notes ,columns,column comments.). Is there is any way to customize the report in such a way that I can remove some columns (mostly the empty ones) from the report and add the column comments along with the column table than a new column comments table.
Please let me know ,is there is an option to customize the report .
Note: I even tried generating the report using the search then report , but it doesn't give a complete report (i was only able to generate a report on column or table name or constraints , not all together.)
Thanks,

Thanks for the immediate reply.
I checked on the DM again, the report comes good for the one which has the data type . But now all my data type changed to UNKNOWN and lokks like ,due to this my table report is coming without the "Data Type".

I know how to disaply vertical & horizontal lines.
I've to display a cross line, which resembles " / ".
Any body can help me out

Hi raja,
1. Intersection of vertical and horizontal line
   = criss/cross line
   eg + (plus sign)
2. I don't think (i could n't find)
any ascii character
which could be used in abap for printing puropse.
3. At the most +
   is there, but it won't MIX/MATCH with

Cross line in Ekbe

Hi friends
I have 2 question.
P.S. I am using OO ALV please give me your response in OO ALV because I cann't convert Reuse_alv... codes into OO ALV
1- I am creating a variant it is sorting ebeln and calculate ebelp column in subtotal line. Can I display only subtotal line? I don't want display items in the list. (It is an option. If user want display only totals I want show only totals.)
2- Some users adding items in ekbe table after that they cross line this item. Meaning
    ..... 120,21
    ..... -120,21
How can I block this cross lines in my application? Do you have any technique?
1000000004 10     1 2006 5000000312 E     101     950,000
1000000004 10     1 2006 5000003501 E     101     1.064,000
1000000004 10     1 2006 5000003593 E     102     1.064,000
1000000004 10     1 2006 5000004238 E     101     1.064,000
This lines from my ekbe table. When I select this data I want give only first and last lines. Becuase 2 and 3 lines are cross lined. (They have reference field their reference field is same)
How can I modify my select statement.
Select * from Ekbe Where Ebeln = p_ebeln and ebelp ? p_ebelp and bewtp = 'E'.
Sorry for my poor english

Hello Mehmet,
To display only subtotals lines, do as follows. I will give you an example using program BCALV_GRID_DEMO, which is an example program for ALV grid.
Run the program to display the data. Select the column Airfare and select the total/aggregation button (the green sigma sign). This produces totals on Airfare.
Now select on the ID column, and click the subtotal button (next to the total button). This produces subtotals by the ID column.
Finally, use the dropdown on the subtotal button, and select the Drilldown Sum Lvl option. Choose the level 1 item (which represents the subtotal for Airline ID). The list now only shows the subtotal items.
This should answer the first part of your question. You can also programatically create layout variants like this to do the same. (There is documentation in the online help).
I am not sure what you mean with the second part of the question.
Regards,
Martin

SQL Developer Data Modeler Information Flow descriptions

Hello
I am new to SQL Developer Data Modeler. Is there a way to display on the Data Flow Diagram the descriptions on the Information Flow lines.
Regards
Ade

1) Is there a cross reference report so that I can check my information structures on the DFD diagram with the attributes defined at Logical Model diagram?you can use "File>Export>To Reporting Schema" functionality to export your design into Oracle database. Two tables there give usage of attributes/entities in processes - DMRS_PROCESS_ATTRIBUTES and DMRS_PROCESS_ENTITIES. look for "reports\Reporting Schema diagrams" directory under installation of Data Modeler - there are PDF files with diagrams of reporting schema tables.
2) How can I create a copy (synonym) for any of my information stores or external agents on the same DFD diagramgraphical synonyms are supported only for objects in Logical and Relational models.

Network data model for public transport

Hi,
I've been playing with Gis for the last 10 years and now I am enrolled in a project to find best way to go from one point to another in Barcelona (Spain) locations, using the public transport network.
The goal is to get a route, from one address to another (both given as inputs), formed by:
-     a 1st piece of path walking to the bus stop
-     a 2nd piece of path involving the bus used to go from one bus stop to another
-     optional 3rd piece of path with a second bus
-     the last piece of path to walk from the destination bus stop to the destination address.
This is a nice problem to resolve with a quite good looking software like the Oracle NDM. I know the big problem will be to put all the data in the right format.
But the question I’d like to share with you would be to approve or improve the algorithm I am thinking to resolve this:
STRUCTURE
Network Data Model NDM_1: creation of a SDO spatial network with all the streets and cross-roads to walk through
Other NDM_2 to store the bus stops with the bus-route-linking information.
     The reason to put them separately is for easily maintenance (a priori).
     [A second approach perhaps would be to put the bus stops as nodes of NDM_1 also]
ALGORITHM
1. Look for bus-stops near the geolocated origin address. (say listing BS_ORIG_list)
2. Look for bus-stops near the geolocated destination address. (say listing BS_DEST_list)
3. Search through NDM_2 for possible correspondences between BS_ORIG_list and BS_DEST_list through single bus line or by two different bus lines applying a network constraint.
(if not correspondence found or if more than 2 bus lines needed, abort by app requirement)
4. Find the walking paths needed to complete the various routes found in step 3 to get from address origin to destination
5. Order the results by time spent or by meters to walk.
Sure there might be improvements to this solution and also other ways to face such a common problem.
Thanks in advance,
David Foix

Hi Andrejus,
Thanks for answering.
I read through your thread already...
I understand and agree it would be a multimodal network. But what would that mean in the time of storing the data and asking for the route?
But I am still doubting the way to query for the resulting route. Having two adresses to join, would there be a nice function or procedure to ask for the route giving preference to walk the minimum meters and use preferently the bus network?
Or should I rely on the first algorithm I proposed? I thought there would be a nicer solution.
In your case, "road transport, railway transport, naval transport and air transport" I understand it would be a case to use different networks as they don't share spatial geometry, only some nodes..isn't it? Did you have the need to join all of them to find route solution giving preference to one of them?
Regards,
David

Copy data models and reports from BW 3.1 to NW 2004s

Hi experts,
Our client has two BW servers: BW 3.1 and BI 7. BW 3.1 contains lots of data models and reports. And the BI 7 server is newly installed.
Now we want to copy these data models and reports from BW 3.1 to the new BI 7 server. Are there any solutions for this?
Thank you very much in advance.

Hi Frank,
Sounds like a cross version transport is needed.
This is a solution we have used to do what you want to do:-
Create and release a transport as per normal.
Copy and transport the files from the source system (BW 3.1) e.g /usr/sap/trans/data & /usr/sap/trans/cofiles to the same folders on the target system.
Basis help is needed here.
From here onwards using stms_import should help you in the normal manner.
Works a treat.
Have transported the following all correctly appearing as 3.x data models in NW2004s.
DSO objects.
Cubes
Transfer/Update rules
Reports.
Cheers,
Pom

Some observations on my first use of Data Modeler Beta

First of all, I can see this tool has a lot of promise.
I hope Oracle keeps at it, it could turn into a real winner if all the features I see being worked on mature.
Thanks!
Here are a few observations on things that I found non-obvious or tedious to do.
1. When designing an entity, I want to give it a name, a definition, attributes and keys. I want that process to be quick and require the minimum amount of mouse-clicking/navigation fiddling as possible. The current way of defining the attribute's datatype and size is painfully slow. I have to click to get a pop-up. Then I have to click to choose from a set of categories. Then I have to click on a dropdown list. If I try to use the down-arrow on the dropdown list, it works, but not if I go past the one I want. The up-arrow won't take me backwards in the list, so more clicking. It's just a nasty, slow interface to do a simple task that I have to do a thousand times in a data model. If I need to change the size of something, back I go thru the entire process all over again.
That makes it doubly slow to work in the most natural way, which is to list the attributes and the datatypes, then come back and refine the sizes once the model is maturing and relatively stable.
2. Adding an additional attribute requires a mouse click instead of a down-arrow. That means I have to take my hands off the keyboard to add a new attribute. Maybe there is some short-cut key that does that, but I have better things to do than memorize non-standard keyboard mappings. Make the down/up arrows works as they should.
3. Adding the comment that describes the attributes is not quite as slow, but still requires more keystrokes/mouse movements than it should. It's hard enough to get developers to document their attributes, don't discourage them.
4. I can't see the list of attributes, data types, sizes, key/mandatory settings, and the comment at one time while editing the entity. Makes it harder to grasp what all the attributes mean at a glance, which slows down the modeling and the comprehension of an existing model.
5. All the entities I created had primary keys with columns in them. But when I tried to have it build a physical model, it complained that some relationships had no columns in them. For the life of me, I couldn't figure out how to fix that. Never had that problem in any other case tool.
6. Getting it to generate DDL was awkward to find. Make it something obvious, like a button on the toolbar that says "Generate DDL".
7. Apostrophes in the Comments in RDBMS are not escaped, so the generated DDL won't run.
8. For the ease of use/speed of use testing on high-volume key tasks, make the developers do the task 1000 times in a row. Make them use long names that require typing, not table A with columns c1, c2 and c3. Long before they get to iteration 1000 they will have many ideas on how to make that task easier and faster to do.
9. Make developers use names of things that are the maximum length allowed. For example, for a table name in oracle, the max length of the name is 30 characters. The name of one testing table should be AMMMMMMMMMMMMMMMMMMMMMMMMMMMMZ. That's a capital A followed by 28 capital M's and a capital Z. For numbers, use the pattern 1555559. If the developers can't see the A and Z or 1 and 9 in the display area for the name in the default layout for the window, they did the display layout wrong. For places where the text can be really long, choose a "supported visible length" for that field and enter data in the pattern AMMMMMMMMMMMMMMMQMMMMMMMMZ, where Q is placed at the supported visible length. if the A and Q don't show, the layout is wrong.
10. SQL Developer has quite a few truly gooberish UI interaction designs and I can see some of that carrying over to the Data Modeler tool. I really recommend getting a windows UI expert to design the ui interface, not a java expert. I've seen a lot of very productive windows user interfaces and extremely few java interfaces suitable for high-speed data entry. Give the UI expert the authority to tell the java programmers "I don't want to hear about java coding internals - make the user interface perform this way." I think the technical limitations in java UIs are much less than the mindset limitations I've seen in all to many programmers. That, and making the developers use their code 1000 times in a row to perform key tasks will cause the UI to get streamlined considerably.
Thanks, and keep up the good work!

Dear David,
Again thank you for your valuable and highly appreciated feedback. Find included a more elaborated answer to your observations:
*1. When designing an entity, I want to give it a name, a definition, attributes and keys.*
In the new Early Adopter Release, a "SQL developer like" property window has been added for Entities and Tables. For each attribute/column you will have the ability to add name, datatype, Primary Key, Mandatory and comment from one and the same screen
*2. Adding an additional attribute requires a mouse click instead of a down-arrow.*
An enhancement request has been created
*3. Adding the comment that describes the attributes is not quite as slow, but still requires more keystrokes/mouse movements than it should.*
In the new Early Adopter Release, a "SQL developer like" property window has been added for Entities and Tables. For each attribute/column you will have the ability to add name, datatype, PK, M and comment from one and the same screen
*4. I can't see the list of attributes, data types, sizes, key/mandatory settings, and the comment at one time while editing the entity. Makes it harder to grasp what all the attributes mean at a glance, which slows down the modeling and the comprehension of an existing model.*
See former answers. For meaning of attributes you can also use the Glossary and Naming Standardization facilities: see Tools Option menu, Glossary and General Options for naming standards
*5. All the entities I created had primary keys with columns in them. But when I tried to have it build a physical model, it complained that some relationships had no columns in them. For the life of me, I couldn't figure out how to fix that. Never had that problem in any other case tool.*
A Bug report has been created. Issue will most probably be solved in the nexr Early Adopter release
*6. Getting it to generate DDL was awkward to find. Make it something obvious, like a button on the toolbar that says "Generate DDL".*
An enhancement request has been created.
*7. Apostrophes in the Comments in RDBMS are not escaped, so the generated DDL won't run.*
A bug report has been created
*8. For the ease of use/speed of use testing on high-volume key tasks, make the developers do the task 1000 times in a row. Make them use long names that require typing, not table A with columns c1, c2 and c3. Long before they get to iteration 1000 they will have many ideas on how to make that task easier and faster to do.*
I aplogize, but I don't understand clearly what you want to say with the use/speed of use here.
*9. Make developers use names of things that are the maximum length allowed.*
Our relational model is for use for not just Oracle, but also DB2, SQL Server and in the future maybe other database systems. Whicjh means that we can't taylor it to just one of these database systems. However you can set maxinum name lenghts by clicking right on the diagram and select Model Properties and here you can set naming Options. Here you can also use the Glossary and Naming Standardization facilities: see Tools Option menu, Glossary and General Options for naming standards
*10. SQL Developer has quite a few truly gooberish UI interaction designs and I can see some of that carrying over to the Data Modeler tool.*
Fully agree. As you will see in our next Early Adopter release we have started to use SQL Developer like UI objects.

ORACLE reports Build 10g - Data Model - query - If statement in Alias ?

I have the following select statement. It has the alias Survivors, Deaths and "All
With the ORACLE reports Build 10g - Data Model - I have the following query statement. I require the alias to change. Can the following be done.
Cases". Is it posible to use :P_LANGUAGE variable to say that -- IF :P_LANGUAGE = FRENCH THEN alias are Survivants for survivors, Décès for Deaths, Tous_les_cas for All Cases. Please advise
SELECT ALL T_NTR_MULTIBAR.CAT, T_NTR_MULTIBAR.NUM_CASES_LEFTBAR AS Survivors,
T_NTR_MULTIBAR.NUM_CASES_MIDDLEBAR AS Deaths, T_NTR_MULTIBAR.NUM_CASES_RIGHTBAR AS "All Cases"
FROM T_NTR_MULTIBAR
WHERE INSTANCE_NUM = :P_INSTANCENUM
order by ORDERS

It is no problem, you can automatically change the complete query before the report is running, which delivers you different kind of values. But the alias names does not change in the group of the data-model, although two query are running with different alias names at different times. In the data model you see the alias names of the first implemented select statement, which are the column fields in the layout.

External Data Refresh Failed. We cannot locate a server to load the workbook Data Model. ThisWorkBookDataModel

Hi All,
I have been trying to fix this for days now. I have tried solutions in many articles but to no avail. So while the error message is something you may have seen may times, I just can't find a solution in my case.
This is the error:
And in text just in case the image isn't viewable:
"External Data Refresh Failed. We cannot locate a server to load the workbook Data Model. We were unable to refresh one or more data connections in this workbook. The following connections failed to refresh: ThisWorkBookDataModel."
What is worse is I have checked the ULS (SharePoint Trace Logs), the Event Viewer Logs and the OWA Logs and I cannot find a specific error that would help pin point the problem.
Excel Workbook
So what am I doing? I have an Excel 2013 workbook and I create an "SQL Server" connection to the AdventureWorksDW database, add a pivot table and a pivot chart, test in in Excel and all works fine.
I save the Excel workbook to SharePoint 2013 and then select "Data" then "Refresh All Connections" and then I get the error in the picture above.
Even more puzzling is I have another Excel workbook that also has pivot tables and pivot charts in the AdventureWorksDW2012Multidimensional cube database in "SQL Analysis Services" and this works fine. Hmmm.
My Environment
My environment is Windows 2008 R2 Server, SharePoint 2013 with the April Service Pack1 and a separate server with OWA2013 SP1. It has an SQL Server 2008 R2 database which has been upgraded to SQL Server 2012.
Data Model Settings
In Excel Services this is set to my server name which is "server-name". As I do not have instances all I can enter is the server name. As this works everywhere else including the workbook outside of SharePoint I do not think this is the problem.
But I could be wrong.
Unattended Account
I have set this up for the PowerPivot Services App and Excel Services App.
ODC Connections in Excel
I have tried all 3 authentication modes, Windows, Secure Store ID and "None" which is the unattended account. I have not tried the other connection types, should I?
Not in WOPI
I am not in WOPI mode.
AD Accounts
I have added permissions in the SharePoint Services and SQL Server, and as they work in Excel outside of SharePoint, I do not think it is a permissions issue. I could be wrong of course, but the problem is in one of SharePoint, OWA, AD,
SQL Server, Excel, and Windows Server.
Isolate the Error
Below is a list of errors I think are relevant but they do not tell me much. The SharePoint logs are not really giving me an error that tells me what to do and where to do it, or even why it cannot refresh, (perhaps not noticeable by the untrained eye).
Problem with SQL Server Not Analysis Services
So my cube database in analysis services works fine in SharePoint/OWA but not the databases in sql server. This is my best clue but I have no idea what it means. Why would it work with an Analysis Services connection but not an "SQL Server" connection?
It Works Outside of SharePoint
If I run the excel worksheet outside of SharePoint all works fine. When inside OWA this is where the refresh error occurs.
Errors from Event Viewer on SharePoint Server using ULS Viewer
"Failed to create an external connection or execute a query. Provider message: There are no servers available or actively being initialized., ConnectionName: , Workbook:"
"Refresh failed for 'ThisWorkbookDataModel' in the workbook 'http://server...'. [Session: 1.V22.26itT0lx8piNFeqtuGVhN214.5.en-US5.en-US36.98c0e158-9113-46e9-850e-edda81d9ed1c1.A1.N User: 0#.w|ad\testuser1]"
And an error in the ULS under the "Data Model" category:
"--> Check Deployment Mode (server-name): Fail (Expected: SharePoint, Actual: Multidimensional)."
This last error, as it turned out, defined the problem concisely, although I was yet to work out what it meant in some detail.

I finally solved this myself (or should I say with the help of several key articles).
The refresh did not work because the database was not in "SharePoint Mode". Yes, SQL Server has modes, 3 of them in fact.
If you installed SharePoint to the default SQL instance which would be called <servername> then you cannot use this default instance for Excel 2013 workbooks in OWA 2013 because the refresh only works if the database is in SharePoint mode.
So what are these 3 modes? The Deployment Mode property in the msmdsrv.ini file has them as:
0 = Multidimensional mode (the default whenever you install SQL Server normally)
1 = PowerPivot for SharePoint mode
2 = Tabular mode mode
How do you know what mode you are in? That's easy, open SQL Studio Manager and connect to all your SQL database engine instances (ignore Analysis Services or SSRS as they are not database engines). If you only have the default instance then that is almost
definately in Multidimensional mode which is the default and what SharePoint installs its databases to.
You must have an instance called <servername>\POWERPIVOT. This instance is the "sharepoint mode" needed, and the default instance name when you install an SQL instance in this mode.
If you don't see <servername>\POWERPIVOT in SQL server then you are not in "sharepoint mode". It is more accurate to say, you do not have an instance that is in sharepoint mode. This is because you cannot simply switch modes on an SQL server.
You have to install a new instance in the required mode, thats the only way.
That's easy enough. Load up the SQL Server setup CD and run setup. Install a brand new instance and select "SQL Server PowerPivot for SharePoint" when you get there in the wizard.
Now you will have the default instance that stores all the SharePoint databases and that is in mode 0, and a new instance called <servername>\POWERPIVOT that is in mode 1. The "<servername>\POWERPIVOT" instance connection is what you
will use for Excel 2013 when rendering in OWA 2013.
You also need to ensure OWA 2013 is not in WOPI mode for Excel worksheets. See the last link below for more information about WOPI.
Next you should go to the Excel Service App in CA and click Data Model Settings and add the <servername>\POWERPIVOT instance.
Then you have to either turn off the firewall on the SQL server machine, or create an inbound rule on the Windows firewall to open the TCP port for the <servername>\POWERPIVOT instance:
1. Start Task Manager and then click Services to get the PID of the MSOLAP$InstanceName.
2. Run netstat –ao –p TCP from the command line to view the TCP port information for that PID.
Finally, you can now create Excel 2013 workbooks that run in OWA without refresh errors, as long as you are connecting to the <servername>\POWERPIVOT instance. Hooray.
