Transporting Data models in SAP HANA

Hi All,
I was trying to understand how data models can be transported in SAP HANA and came across the different options in the Export option of hana Studio like exporting with Delivery unit, Developer mode, etc.. Can someone please elaborate on the differences between each and the scenrio when each should be used?
Thanks,
Sam

No Justin, haven't used in any "production" environments till now since the client am working for is still to be upgraded to SP7. At internal system we are doing some R&D in those lines and developing artifacts from "Development" perspective.
Here i shared this link for reference itself.
Also i think using Development perspective for modelling is what is being suggested going forward in blogs like this
6 Golden Rules for New SAP HANA Developers
May be John Appleby and his team are already using "Development" perspective consistently

    Hi Patrick ,
    What user did you use to start JSPM? Was it <sid>adm? Also based on the error it seems there is something wrong with DataModel.xml JSPM uses. And you've mentioned it was copied from another system if I get it right.
    So as a quick workaround you could try removing:
    - Jspm.DataModel.xml
    - Jspm.J2EE.DataModel.xml
    - Jspm.JSPM.DataModel.xml
    from ../j2ee/JSPM/data/variables directory and give JSPM another try.
    Please make sure the rest of the XMLs are in place otherwise JSPM won't start.

  • Regarding Modeler in SAP Hana Studio

    Hello Experts,
    I am trying to connect to SAP HANA Trial System with  my in house NSP System through Business Object Data Servicies.
    I have completed the steps till configuring the import server in HANA studio now when click on "Import Link"  Under Content,  i am not getting "information modeler" option to get table structure.
    Please help on this.
    Please find the screenshot attached here.
    Regards
    Bhasin

    Bhasin,
    To import table structure, Click on SAP HANA Content --------> Selective Import of Metadata.
    Once you click on above, it will ask you to mention Source connection details and type of import objects like tables & extractors.

  • Dimensional Modeling on SAP Hana

    Hello,
    I am a newbie on SAP hana, so need help from experts / gurus.
    Imagine the following Scenario ---> Oracle ERP is the source System and we want to build a Analytic Solution on Hana. Also assume that tables can be replicated into SAP Hana
    Questions
    1)For any kind of reporting / Analytics? Should we build a traditional Datawarehouse on Hana with all the features found in a star schema like surrogate keys, conformed facts and dimensions etc? or  use only attribute views / analytical views provided as default and build datawarehouse model on top of this? In the second case, do we still need surrogate keys or how can we merge slowly changing dimensions?
    2)Where can be push the transformation logic? Into ETL tool or use Hana provided sql script? and also where do we do this transformation, outiside hana where we do all transformations and load only data into normolized format? or within hana using scripts?
    3) In any case is dimensional modeling really required on Hana? if not how can we map business process and do analysis on them? is it by means of only the views provided by Hana?
    Your help is much appreciated.
    Thanks!

    Hi Rajiv,
    I'm no expert either and am just beginning to learn HANA, but here are my thoughts (community, please correct me if I am mistaken.):
    1. HANA leverages existing data modeling theories, such as the entity relationship model. This model is simply a way of organizing tables in a way that makes sense for reporting. For example, the star schema, optimized for analytical reporting. The HANA view is similar to a universe, it allows the end user to connect to it from their BI tool. In the background, the modeler still needs to pull in tables, create joins, leverage primary and foreign keys, etc. So in short, traditional modeling practices and theories still come into play.
    2.  If extracting and transforming data using SAP's Data Services, the transformation of data will happen in HANA, using the Data Quality Management GUI.
    Just as a side note, HANA has 3 methods of extracting
    data:
    Data Services
    SAP Replication
    Server
    SAP Landscape
    Transformation
    3. Yes, dimensional modeling is still required. At the end of the day, HANA is still a database. We
    haven’t changed the theory of data modeling, it still needs to happen, our approach is just different.
    Hope that helps.

  • Problem when transporting data model

    Hi,
    I currently have a problem when I send my transport to Q/A.  I cann see the info objects that I am sending.  I have replicated and refresehd the tree but no info objects are shown.  I have created the transport by including the info object catalogs in process before.  Does anybody have any ideas?
    thanks.

    Hi,
    This is the message I get back from the transports:
       Activate inactive runtime objects        25.04.2008 16:09:44    (0) Successfully Completed
       Activate inactive runtime objects        25.04.2008 16:19:36    (0) Successfully Completed
       Activate inactive runtime objects        25.04.2008 16:21:28    (0) Successfully Complet
    So you think I should transport the info object first , and then the catalogs.  What i've noticed is that when I check my data sources for my source system, the proper characteristics cannot be found and my transfer rules cannot automatically be activated.
    Let me know what you think.
    thanks

  • What is SAP HANA DXC ???

    Hi SAP HANA Experts,
    Can anyone you tell me what is SAP HANA DXC ???
    Is it a Add-On Or inbuilt software component available with SAP HANA DB Package Itself
    Do we need to download the SAP HANA DXC individually ???
    What is the path of the DXC Software component in SMP to view it

    Hello guy,
    The SAP HANA Direct Extractor Connection (DXC) is a means for providing out-of-the-box foundational data models to SAP HANA, which are based on SAP Business Suite entities. (No add-on need to be installed). DXC is also a data acquisition method for SAP HANA. With DXC, SAP Business Content DataSource Extractors are available to deliver data directly to SAP HANA

  • SAP HANA Performance Optimization

    Hi Experts.
    Is there any documentation out there that relates to optimizing SAP HANA components such as optimizing the SAP Hana models, data loading using SAP LT, etc. I would like to fine-tune what I have already built.
    Thanks,
    Regards,
    Thatoyame
    Email: [email protected]

    Hello Thatoyame,
    since HANA is pretty fast in so many cases, there isn't much available about general performance tuning. In cases where performance isn't great, a detailed root cause analysis (i.e. trace) is the way to go. See SAP HANA Appliance Software – SAP Help Portal Page (Admin section) for some details on tracing.

  • SAP HANA modelling Standalone

    Hello Experts,
    We are in the process of HANA Standalone implementation and design studio as reporting tool. When I am modeling, I did not figure out answers to some of the below questions .Below are the questions. Experts, please help.
    Best way of modeling: The SAP HANA LIVE is completely built on calculation view; there are no Attribute and Analytical views. I have got different answer why there is only Calculation view and there are no Alaytic view and Attribute views. We are in SP7 latest version. This is a brand new HANA in top of non-SAP (DB2 source).  What is the best way to model this scenario, meaning, can we model everything in the Calculation view’s like SAP HANA live or do you suggest using the standard attribute, analytical and calculation views to do the data model. Is SAP moving away from AV & AT to only calculation Views to simply the modeling approach?
    Reporting: We are using the design studio as front end tool. Just for example, if we assume that we are
    Using the BW, we bring all the data in to BW from different sources, build the cubes and use the bex query. Here in bex query we will be using the restricted key figures, calculated key figures calculations etc. From the reporting wise, we have the same requirements, calculations, RKF, CKF,Sum, Avg etc. if we are Using the design studio on top of standalone HANA, where do I need to implement all these calculations? Is it in different views?  (From reporting perspective, if it’s BW system, I would have done all the calculations in BEx.)
    Universe: If we are doing all the calculations in SAP HANA like RKF. CKF and other calculations , what is the point in having additional layer of universe , because the reporting compnets cam access the queries directly on views .In one of our POC , we found that the using universe affect performance.
    Real time reporting: Our overall objective is to give a real time or close to real time reporting requirements, how data services can help, meaning I can schedule the data loads every 3 or 5 min to pull the data from source. If I am using the Data services, how soon I can get the data in HANA, I know it depends on the no of records and the transformations in between the systems & network speed. Assuming that I will schele the job every 2 min and it will take another 5 min to process the Data services job , is it fair to say the my information will be available on the BOBJ tools with in 10 min from the creation of the records.
    Are there any new ETL capabilities included in SP7, I see some additional features included in SP7. Is some of the concepts discussed are still valid, because in SP7 we have star join concept.
    Thanks

    >> I haven't read any "official" guidance to move away from typical modeling approach, so I'd say stick with the usual approach- AT, then AV, then CA views. I was told that the reason for different approach with HANA Live was to simplify development for mass production of solutions.

    >> I'm not a BW guy, but from a HANA perspective - implement them where they make the most sense. In some cases, this is obvious - restricted columns are only available in Analytic Views. Hard to provide more complex advice here - it depends on your scenario(s). Review your training materials, review SCN posts and you should start to develop a better idea of where to model particular requirements. (Most of the time in typical BI scenarios, requirements map nicely to straightforward modeling approaches such as Attribute/Analytic/Calculations Views. However, some situations such as slowly-changing dimensions, certain kinds of calculations (i.e. calc before aggregation with BODS as source - where calculation should be done in ETL logic) etc can be more complex. If you have specific scenarios that you're unsure about, post them here on SCN.
    Universe: If we are doing all the calculations in SAP HANA like RKF. CKF and other calculations , what is the point in having additional layer of universe , because the reporting compnets cam access the queries directly on views .In one of our POC , we found that the using universe affect performance.
    >>> Depends on what you're doing. Universe generates SQL just like front-end tools, so bad performance implies bad modeling. Generally speaking - universes *can* create more autonomous reporting architecture. But if your scenario doesn't require it - then by all means, avoid the additional layer if there's no added value.
    Real time reporting: Our overall objective is to give a real time or close to real time reporting requirements, how data services can help, meaning I can schedule the data loads every 3 or 5 min to pull the data from source.

    >>> Not exactly sure what your question here is. Your limits on BODS are the same as with any other target system - doesn't depend on HANA. The second the record(s) are committed to HANA, they are available. They may be in delta storage, but they're available. You just need to work out how often to schedule BODS - and if your jobs are taking 5 minutes to run, but you're scheduling executions every 2 minutes, you're going to run into problems...

  • Creating Logic and modeling for SAP BW datasource in SAP HANA views and SLT

    Hi to all,
    I have small question.
    We have BW system and SAP ECC as source system and to get data from SAP ECC source system we are using SAP ECC Standard data source.
    Now we required to, create modeling in SAP HANA by use of HANA View and get data from SAP ECC source table via SLT.
    So we can replicate same modeling,as we done in SAP BW system.
    But  my question is that, as SAP ECC standard data source hit multiple table and do run-time calculation, before sending to SAP BI.
    How we can derives such calculation and logic, in our HANA studio, because as we know in SLT data transformation can be done in limited way also
    in view we can not drive such logic via SQL script ?.
    Is there any way we can do such modeling and logic in SAP HANA ?
    or
    is there any standard document for this type of case, which we can use ?
    Note: We don't want to use SAP DS or DXC for data loading to HANA, as  we want it in more real time.
    Regards
    Pavneet Rana

    Thanks for reply,
    As SLT is based on ABAP, so we can write complex logic in it.
    But if we talk about SAP ECC standard data source, they have complex logic, based on multiple table.
    So we need to write code from scratch in SLT to derive same result. but it will be huge time consuming , and required good ABAP skills, also it will lead to bug in code.
    Also it will reduce the real time performance of SLT, due to complex logic.
    Second option is procedure via SQL script, which is again huge effort in term if logic and can lead to error/bug in logic.
    Does we have any other way or architecture to do this is very simple way, with high performance and less error issue.
    Regards
    Pavneet Rana

  • How to use Variable in SAP HANA Information Modeller?

    Hello Folks,
    I have created a variable in Information modeller of SAP HANA Studio on top of an Analytical view (Regional Sales).  This variable is SingleValue (Multiple Value Selections).  This variable should prompt me the name of Country/Regions but somehow this is not working when I am using data preview and Analysis tab of data preview.
    Could you please enlight me where I am going wrong? or Let me know if is there any other forum for this.
    P.S : I am using SAP HANA studio on Cloud.
    Regards
    Muffazzal Fani

    Hi,
    After you created that variable as mentioned above, did you apply this variable on your LAND1 attribute.
    How: Open Analytic View --> on right-side you see the attributes,measures etc. >right click on 'LAND1' and select>
    'Apply Filter'--> In the drop-down  select your created variable and activate.
    I assume the above should resolve your issue. Please let me know if it helps.
    Revision: I mean the HANA version you are using.

  • Migrating SAP BW into Oracle data model

    We have a requirement where the exisiting data from SAP BW needs to be migrated into Oracle. Since I do not have any prior SAP BW experience, I wanted to ask the forum on what their thoughts are in converting the data model from SAP BW into Oracle. Would that be straight forward conversion for the fact and dimension tables into Oracle or are there certain things we need keep in mind while designing the data model in Oracle. For ex: indexes, keys, attributes etc if they are handled any differently between the two systems.

    Hi
    ERwin will not give you the functionality to derive the logical data model from SAP BW automatically, however Saphir from Silwood Technology (www.silwoodtechnology.com) does allow you to extract the detailed metadata from the SAP BW system ( as well as from other major standard or customised ERP applications - SAP itself, Oracle, Siebel, Peoplesoft and JD Edwards). Once this information is brought into its own repository, Saphir provides a range of powerful search and view capabilities to allow you to isolate the data you are interested in and then export that information to ERwin (or any other leading Modeling tool).
    Saphir will provide you with details of the relationships and detailed definitions within SAP BW.
    Hope this helps

  • Can't Upload Sample Data to SAP HANA Sandbox-Can't Navigate to SQL Editor

    Hi HANA Freaks,
    I want to load sample data E2EModelingTutorialData into SAP HANA Sandbox but the following steps are required.
    To load the data to your SAP In-Memory Database do the following:
    - Copy the files to your database server.
    - Copy all SQL statements in the file SQLStatements.txt in an SQL view of your In-Memory Computing Studio
    - Modify the load statement according to your file location, e.g.
      LOAD FROM '<TO BE CHANGED>\EFASHION_SHOP_FACTS.CTL';
      could become
      LOAD FROM '/tmp/EFASHION_SHOP_FACTS.CTL';
    - Run the SQL statements which takes some minutes
    - Verify that all the files *bad.txt are of size 0 which means that the import of all records was successful.
    At steps 2 cant navigate to the editor where the SQL statements will be pasted for execution.
    Pls can some one give a step / step tutelage to achieve this?
    Many Thanks !

    Hi,
    For the step2,
    1. Right click on the navigator panel,
    2. Click to SQL Editor, where you can write/paste the SQL code
    3. Click on the execute link.
    Hope it is useful.
    Thanks
