Data Modeler still hangs

Hi,
since the first thread 'Data Modeler hangs' is marked as answered. I try a new one. I still had this problem that modeler hangs when trying to open or save a file.
I played around and found following solution which works for me :
Download data modeler with JRE and install it. If the modeler hangs when trying to open a file, edit datamodeler.conf file and set javahome manually e.g.:
SetJavaHome C:\Program Files\OSDM2.0\datamodeler\jdk
It seems, that the standard setting during installation for JavaHome does not work under all circumstances.
I am on Windows XP SP3 on a locked down PC

Thanks for the help Ivan & Philip - made the change to 4GB RAM in the conf file but that did not solve the problem.
Process
1. Open view properties
2. Click Test Query button - works fine
3. Click Query button to edit query. Query builder never opens - monitor shows 100+ % CPU. Have to do force quit to close.
Reverse - same thing
1. Edit query 1st - no problem
2. Test query - after db connection dialog - the test never execute. 100+% CPU again.
I can edit as many view queries as I want and it works fine.
or
I can Test as many queries as I want - no problem
When I try to do both on the SAME view - then I get trouble.
Seems like an issue in the view edit dialog (only on Mac - never had the issue on a PC)
FYI - I am on 64 bit Java.

SQL Data Modeler on MAC consumes lots of CPU but still hangs

Running data modeler version 3.1. on mac 10.7.3 - 64 bit both. Mac has got core i7 processor with 8Gigs or RAM, so no shortage of resources here.
Got mail open as well as normal SQL Developer exploring the database tables and running queries. So plenty resources still available.
I 'm experiencing intermittent conditions where I'm editing a card or entity properties and then developer goes into a "go very very very slow strike" mode. It consumes 99% CPU with average 40 threads running and approx 400 megs of memory consumed.
It then takes for ages to respond to any inputs on the commit/cancel/apply buttons - more than 10 minutes! I once tried the "Force Quit" option - bad bad mistake. It lost all the task bar option - only had the "file" option on the task bar left!
Anybody experienced the same or with a solution to this ?

Data Modeler hangs

I'm using the SQL Developer Data Modeler, and when trying to save my work with "Save as" or "Save" (I've tried both) the program hangs. Has this happened to anyone? What is the workaround? This never happened to me with the Early-Adapter version.
Thank you.

Hi,
same with me here. I downloaded and installed datamodeler-2.0.0-570.zip. I am unable to "save" , "save as" or use the "open" dialog. As soon as I select one of these menu items datamodeler hangs and can only be stopped using the task manager.
I had datamodeler running as a single application but it still hangs when I try to save or open a file.
Version:
Windows XP Service Pack 3 (Build 2600.xpsp_sp3_gdr.090206-1234)
Is there any workaround ?

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.

Powerpivot Error on Refresh -- "We couldn't get data from the data model..."

I'm using Excel 2013 and Windows 8.1. I have a spreadsheet I've been using for over a year, and I've just started getting this error message when I try to refresh the data.
"We couldn't get data from the Data Model. Here's the error message we got:
The 'attributeRelationship' with 'AttributeID' - 'PuttDistCat9' doesn't exist in the collection"
Any idea how I can fix this problem? I haven't changed anything related to that particular attribute. All the data is contained in separate sheets in the workbook, so there are no external sources of data.
Thanks.
Jean

Thanks for all the suggestions.
I found a slightly older version of the spreadsheet that still refreshes properly, so I don't think I have any issues with the version of Excel or Power Query. (I've had this same error before, and I believe I applied the hotfix at that time.)
I think this problem started after I updated a number of the date filters in the pivot tables. I haven't made any changes to the data model, and the only updates I've made were to add data (which I do all the time), and to change the date filters on
the pivot tables.
As suggested, I added a new pivot table querying one table (the table with the attribute that shows up in the error message), and it worked fine. I can also refresh this pivot table.
Then I tried adding a pivot table which went against several tables in the data model (including the table in question). The pivot table seemed to return that data properly. However, when I tried to refresh it, I got the same error message ("we
couldn't get data from the data model...").
Dany also suggested running the queries one at a time to see which one is in error. Without checking all the pivot tables, it appears that any which use the table "HolePlayedStrokes" generate the error (this is the table with the attribute
mentioned in the error message). Pivot Tables without that particular table seem to refresh OK. Unfortunately, that is the main table in my data model, so most of the pivot tables use it.
Any other suggestions? I'd be happy to send a copy of the spreadsheet.
Thanks for all the help.
Jean

Data Model won't open

I have created a PowerPivot data model using Excel 2013. It runs fine on my computer (the one where I built it), but will not open in other computers. All computers have the same 64 bit version of PowerPivot 2013 and run on Windows 8.
The primary data model table contains about 170,000 rows, 20 raw data columns, 2 calculated columns, 30 calculated fields (measures), and there are also a couple of small linked-back data tables with relationships to the primary
table. The data model takes approximately 5 minutes to refresh using my computer when I click 'Update All' (pertains to linked-back tables) on the PowerPivot ribbon in Excel. 99% of that 5 minutes is spent reading the data. However the
refresh time is not really my concern, as the data model will not open at all on any other computer.
It might be worth mentioning that my data model utilizes the 'stdev.p' function (new to PowerPivot 2013). However, I would not expect this to matter since all computers I am trying to run on have PowerPivot 2013.

Hi apple user. I have lost all iPad safari bookmarks. Tried hold home button with sleep button but it doesn't get back my safari bookmarks. I also have reset without erasing my iPad data but still doesn't work. Help me get back my safari iPad bookmarks.

Hi, I have lost all iPad safari bookmarks. Have tried reset without erasing data and hold home and sleep button together but when go to safari all safari bookmarks still lost. Is there any case help me get back my iPad safari bookmarks ? Currently my safari is hanged, can't surf webs or anything. I saw the safari tab on iCloud is on, but I don't know using iCloud. Please help me get back my iPad safari bookmarks. I have contact Apple but could not set chat session. I have my Apple ID registered same with iCloud, also same during the time I have all iPad safari bookmarks lost. My iPad never synced on computer since I bought it with set at local store. Please help me get my iPad safari bookmarks back, thanks.

Hi, I quitted Safari and press and hold the Home and Sleep buttons silmutaneously unti the Ipad turn off and on with the logo Apple appears but it has hanged on and fixed to the point. I do it again hold the Home and Sleep buttons silmutaneously and the Ipad turn off and on again with the Apple logo but it still is hanged on the same point. I have do it a few more time, it still hanged to the same point for few hours with no change (like picture):
I think my Ipad is fault now. I guess I must connect it to the computer with itune, or something. So my case is this: at the moment everytime I hold the Home and Sleep buttons the Ipad always off and reappear with the Apple logo and be hanged on (like the pic), and I need restoring my Ipad Safari bookmarks... so I guess I need using Itune or something to get back the Ipad then using Icloud or blah. Please guide me for the step, Im not sure if connect to PC, if any that my Ipad data would lost, or is there anyway that I also can get back Ipad Safari Bookmarks after connecting to PC, also the how using Icloud. There is no Apple store or service store in my country so I think I must do it my self. Feel free to share your guide, thanks.

Xcode, how do you take an app from an idea to a data model, data structure, or class structure?

Hey everyone!
I'm a beginner xcoder and computer engineering sophomore and have literally spent every hour of the past few weeks reading as much as I possibly can about becoming a developer.
I've found plenty of documentation, and guides on how to do very specific things in xcode and objective-C but am still looking for more information on one topic; how do you decide which data models/structures/controllers etc to use?
I mean, you personally. I've been looking for a resource on this and have not been able to find one. I just finished Apple's iOS Developers Guide and they mention "choosing a data model" but do not describe them in much detail.
The following is what is provided in the guide:
● Choose a basic approach for your data model:
● Existing data model code—If you already have data model code written in a C-based language, you
can integrate that code directly into your iOS apps. Because iOS apps are written in Objective-C, they
work just fine with code written in other C-based languages. Of course, there is also benefit to writing
an Objective-C wrapper for any non Objective-C code.
● Custom objects data model—A custom object typically combines some simple data (strings, numbers,
dates, URLs, and so on) with the business logic needed to manage that data and ensure its consistency.
Custom objects can store a combination of scalar values and pointers to other objects. For example,
the Foundation framework defines classes for many simple data types and for storing collections of
other objects. These classes make it much easier to define your own custom objects.
● Structured data model—If your data is highly structured—that is, it lends itself to storage in a
database—use Core Data (or SQLite) to store the data. Core Data provides a simple object-oriented
model for managing your structured data. It also provides built-in support for some advanced features
like undo and iCloud. (SQLite files cannot be used in conjunction with iCloud.)
● Decide whether you need support for documents:
The job of a document is to manage your app’s in-memory data model objects and coordinate the storage
of that data in a corresponding file (or set of files) on disk. Documents normally connote files that the user
created but apps can use documents to manage non user facing files too. One big advantage of using
documents is that the UIDocument class makes interacting with iCloud and the local file system much
simpler. For apps that use Core Data to store their content, the UIManagedDocument class provides similar
support.
I suppose my question boils down to, how do you decide which structures to use? If you can provide an example of an app idea and how its implemented that would be very helpful and much appreciated!
For example, to implement the idea of an app which allows users to progress through levels of knowledge of a certain subject and rewarding them with badges and such (this is not an actual app just a whim) how would one model that?
Thanks in advance for all your help!!!

Trial and error.
I wish I had a better answer for you, but that pretty much encapsulates it. There is some, but not much, good wisdom out there, but it takes a significant amount of experience to be able to recognize it. The software development community if currently afflicted with a case of copy-and-paste-itis. And the prognosis is poor.
The solution is to be brutal to yourself and others. Focus on what you need and ignore everything else. Remember that other people have their own needs and methods and they might not be applicable to you. Apple, for example, can hire thousands of programmers, set them to coding for six months, pick the best results, and have the end-users spend their own time and monety to test it. If you don't have Apple's resources and power, think twice about adopting Apple's approach. And I am talking from a macro to a micro perspective. Apple's sample and boilerplate code is just junk. Don't assume you can't do better. You can.
Unfortunately, all this takes time and practice. You can read popular books, but never assume that anyone knows more than you do. Maybe they do and maybe they don't. It takes time to figure that out. Just do your best, ignore the naysayers, and doubt other people even more than you doubt yourself.

How to get data model to recognize structure change

I have an extremely complex report that was built almost entirely manually -- except for using the Data Wizard to create the Data Model (multiple queries with multiple groups). The source view that the query Q-1 is based on has changed. It is a change in the precision of the column. How do I get the data model to notice that change? The Width in the Property Palette is still showing 8 when it should now be 16. This is causing the display on the report to be truncated to 8 characters.
I don't want to have to rebuild the data model. It took me 3 days to get it so that it works!
Thanks

PLS OPEN THE QUERY AND THEN CONNECT USING YOUR USER. I THINK WHEN YOU REFRESH THE QUERY AND CONNECT THEN WIDTH IS CHANGE AS THE COLUMN IN THE DATABASE.(i.e. 16)
THANKS,
FAROOQ Thanks for the suggestion. Unfortunately, the same thing happens when I do this as happens if I modify the query with a space (as before); the rows are removed from their groups, and I lose the Source of my calculated fields.
If anyone is interested, I finally found a way to do this:
1. Convert the report into a text file (File>Administration>Convert);
2. open the text file in a text editor;
change the offensive WIDTH settings (make sure to look for all of them);
3. save the text file;
4. then convert it back to a RDF file using the converter.
A round-about way to perform what should be an automatic operation -- but there it is.

Can I pass parameters from a dashboard via a dashboard prompt and presentation variable to publisher report based on a data model with select statements in OBIEE 11g ?

I have a publisher 11g (v 11.1.1.7) report with a single parameter. The report is based on a data model not a subject area. I created a dashboard put a dashboard prompt and link to the report in separate section on the same page. The dashboard prompt sets a presentation variable named the same as the parameter in the report.
The problem was when I created the dashboard prompt, it forced me to select a subject area which I did (though did not want to) and then I created both a column and variable prompts. But clicking on the
report link completely ignored the value that I thought would be passed in the presentation variable to the report.
Side note : My report uses a pdf template for its layout where I have mapped the columns names from my data model to the form fields on the pdf form. I noticed that if I create a publisher report based on a subject area, then I do not have the choice to choose a PDF as a template type for my layout. (I only see BI Publisher Template as a choice).
I see some documentation online that suggest it could be done in 10g.
Thanks
M. Jamal

Ok,
I just tried that and it still doesn't pass anything to the prompt.
I changed the prompt to an edit field and I made the following weblink but when i click the link from an account it doesn't put anything in the prompt and all data for all accounts is shown.
This is the URL maybe I messed something up...

Data Modeler: Editing or creating a view "crashes"

Hi all,
some days ago I've created a view in my relational model using the data modeler (SQL Developer 3.2.20.09). Today I wanted to add some more columns. Unfortunately the property pane doesn't open any more when double clicking the view object (for the tables it still works). No error message is shown. In the logical view a red triangle is shown in the top left corner of the view object.
When I try to create a totally new view then the data modeler /sql developer crashes (doesn't respond anymore)...
What could be the reason?
If also tried with the new version of SQL Developer - there it doesn't work either...
Thanks in advance
Matthias

Beginners guide to PowerPivot data models

Hi,
I've been using PowerPivot for a little while now but have finally given into the fact that my lack of knowledge about data modelling is causing me all kinds of problems.
I'm looking for recommendations on where I should start learning about data modelling for Powerpivot (and other software e.g. Tablea, Chartio etc). By data modelling I mean how I should best organise all the data that I want to analyse which is coming fomr
multiple sources. In my case my primary sources right now are:
Our main MySQL database
Google Analytics Data
Google Adwords data
MailChimp data
Various excels
I have bought two books - "Dax Formulas for PowerPivot" which is great but sparse on data modelling information and "Microsoft Excel 2013 - Building Data Models with PowerPivot" which looks excellent but starts of at I believe too advanced
a level.
Where should a beginner with no experience of data modelling, but intermediate/advanced experience of Excel go to learn skills for PowerPivot Data modelling?
By far the main issues is that our MySQL databases are expansive and include hundreds of tables across multiple databases and we need to be able to utilise data from all of them. I imagine that I somehow need to come up with a intermediary layer between
the Databases and Powerpivot which extracts and flattens the main data into fewer more important tables, but would have no idea how to do this.
Also to be clear, I am not looking at ways of modelling the MySQL database itself - our developers are happy with the database relationships etc, it just the modelling of that data within PowerPivot and how to best import that data.
Recommendations would be absolutely brilliant, its a fantastic product but right now I'm struggling to make the most of it.

Thanks for the recommendations, I am aware of the last two of those and
http://www.powerpivotpro.com/ in particular has proved very useful (TechNet less so).
I will take a look at SQLBI in more detail but from a very casual browse it seems like this too is targeted more at experienced users. There paid courses may definitely prove useful though.
I think what I'm getting at is that there are probably an increasing number of people like myself who have fallen into PowerPivot without a traditional background in databases and data modelling. In my case I have a small business of
15 employees and we were using Excel and PivotTables to do some basic analysis before soon discovering that our data was too complicated and that I needed something. PowerPivot definitely seems to solve that issue and I'm having much
better success now than I was without. I also feel quite competent with DAX and actually building tables from the PowerPivot data model.
What I'm lacking in is the very first step of cleaning and preparing raw data for import and then importing it into Powerpivot and setting up a efficient model. I have to be honest that your links above did bring
PowerQuery to my attention and it seems like a brilliant tool and one of the missing links. I would however still like to see a beginners guide to data import and model set-up as I don't think I've yet come across one either in book or
online form which explains the fundamentals well.

Issue in creating a custom data model from BP

Hi Team
We have a requirement to create a custom data model by copying data model BP. I have successfully created new data model ZP . I have copied the UI for searching from BP. Issue is when i search a business partner ideally it should not display any entries because i have just created the data model, But it is taking entries from BP and getting displayed. Please let me know how to map data model to search UI. I dont see option USMD_MODEL here

Hi Imran,
actually that is not an issue but a designed feature. I'm afraid that you need to re-think your whole project. The explanations is rather simple:
Data model BP in MDG is a so called Re-Use Area data modell. This means that active data (records that are currently not stored in a change request) are saved in existing SAP ERP data base tables like BUT000 for the business partner master data and LFA1 or KNA1 for Vendor or Customer master data.
If you copy data model BP to ZP you still refer to the same active area. You will always find the same active objects - no matter which data model you are actually using for the user interface. The only difference wil occur for objects being currently processed in a change request. In that case a separation between BP and ZP is possible. But this won't help to solve your issue.
From SAP side I can only recommend not to copy BP but to find a different way of integrating your project needs into BP.
Best regards
Michael

Can SAP leverage MM and classification (CL-system) data-model?

Dear all,
At the moment Im working for a telecom company, setting up the Functional Management department activities to manage 2nd line support calls, and general overall application functional support.
One of the issues is simplifying the work of monitoring Item (products, articles etc.) Master Data. Below you can see the data model where Items, their classes, the characteristics of classes and prices are stored.
The Legacy system has the following data-model (as ERD, <a href="http://sapparking2007.freehostia.com/LegacyModel.JPG">LegacyModel</a> )
Main Product (i.e. Nokia 6110)
     - has zero, one or more Characteristics (i.e. 220v cord, 3v battery etc.)
     - has zero, one or more Variants (i.e. Nokia 6110i, Black, Red etc.)
     A Variant (Nokia 6110i, Black)
          - has zero, one or more Characteristics (i.e. 200h stand by time etc.)
          - has zero, one or more Deliveries (i.e. we sell a package)
          A Delivery (certain combination of a package : Nokia 6110i, Red, Prepaid, 1 year)
               - Has zero, one or more Characteristics (i.e. prepaid simcard, free service etc.)
               - Has zero, one or more Delivery Prices (i.e. prices)
               A Delivery Price
                    - Has zero, one or more Characteristics (i.e. 1 month warenty)
                    - Has zero, one or more Prices (i.e. offer price, sales, periods)
Well, almost perfectly normalised data-model.
The implementation in SAP is as follows:
Main Products , Variant and Deliveries are all stored in table MARA.
Product is Artikeltype Z01A,
Variant is type KMAT,
Deliveries is type HAVA and DIEN.
See image:
<a href="http://sapparking2007.freehostia.com/Model01.JPG">Current Data Model</a>
The Characteristics are stored in table CABN etc
The prices are stored in the SD table KONP .. (price condition). etc.
The MARA table is connected to Classes table (KSSK) via the INOB table.
Classes are connected to Classes with in de KSSK table.
The filed that stores Class in the KSSK and the field that stores the Class below are 2 different type of fields (18C , and 50CN) and they would simply wont join in a SAP query.
The filed that stores Item to Class in the INOB and the field that stores the Class in the KSSK are 2 different type of fields (18C , and 50CN) and they would also wont join in a SAP query.
Therefore we have created extra Z. Tables (Types actually) that does the join for us.
Functional Management personnel are not ABAP and SQL people. So we have to keep it simple.
After a training session it proved to be still too complicated. After a Change Request, to create the product structure in a separated, single table, has resulted in a batch job, that create the file periodically, but not all of it. And at the end, you never know if your data is up-to-date.
To me it seems logical to add a (derived) field to the KSSK and the INOB to accumulate the underlying class with the same attributes as the MARA and KSSK, so it can be properly joined. But here there is too much resistant in conjunction with SAP releases etc. AND it seem to be impossible (not sure) to define a type table with a derived field.
To let programmers produce more ABAP is not a clean option either, and yes I realise one can create a sap query on a single table, and add a long SQL statement on Record level.
So the question:
-     Is this implementation the best possible in SAP?
-     How to overcome the unjoinable friendly database?
In other query tools it is possible to create tables as output (on the fly), where the tables can be used as input tables in a next query, and can be joined further.
-     Is this somehow possible in SAP?
I wonder if anyone can shade some light on this approach. We have 2 FTE to monitor 2.5 million products combinations, and the propagation of this data to over 30 sales channels daily.
Thank you in advance for taking the time!
Kind Regards,
Doron.

SQL Developer Data Modeler scripting

Hi,
I'm looking for a new modeling software for my company. SQL Developer Data Modeler (SDDM) has many features that fit my requirements. But there are some things that I'm not sure can be done. I work mostly with Oracle databases but still need to support some legacy and non-sql databases. Please look at problems below and tell me if and how those things can be achieved. Any suggestions for alternative solutions are welcome too.
1) I need to be able process Database Model from command line without human intervention and starting any GUI applications, for example generate DDL script form the model. Does SDDM have any interface for that?
2) I want to be able to export Database Model into a file in a custom (legacy) format.
3) SDDM stores database description in xml files. Is xml format defined anywhere? Are xsd schema files availabe?
4) Is there a SDK available that would allow reading SDDM Database Model into a custom application for further processing?
5) Is there any Java library available that parses Oracle-11-compatible SQL and PL/SQL?
Thank you in advance
Tomasz Grygo

Hi Kevin,
thanks for sharing your thoughts. There will be much more advanced find/search facilities in next version of Data Modeler and scripts also will be covered.
