  • Sap hana DATA MIGRATION OPTION

    Hello,
    SUM can be started from browser and from OS level also by running "./DSUgui".
    So , is there a way to start SUM with DMO option for HANA migration from OS level?
    It is known that SUM with DMO can be started from the browser but we have lower level IE - does not support.
    URL : http://<hostname>:1128/lmsl/sumabap/SID/doc/gui/
    Expecting a reply.
    Thanks and regards,

    Hi,
    For DMO option, you have to invoke the services through browser only. The reason being you need to create the SAPHostAgent Configuration file to start SUM. This configuration file contains the location of the SUM directory and the path to the SUMSTART.BAT files.
    The SAP Host Agent in turn starts two SAPup services.
    In a non DMO scenario, you do not maintain the configuration file and directly start the services. Hope this help.

  • SAP HANA as a data source for Analysis Services

    I tried to use SAP's .net provider for HANA as a data source for an Analysis Services cube but to no avail.   I can connect, create a named query and preview data from the data source view designer but when SSAS actually tries to run the query,
    it wraps the named query in another query and produces a syntax error.  
    For example,  if the named query is "select * from ENTHANA.MARA", 
    SSAS sends a query like this "SELECT [test].* FROM (select * from ENTHANA.MARA) AS [test]"   (Test is the name of the named query).
    I know SSAS wraps queries and that's fine - except that brackets are not a valid way to quote an identifier in HANA.  HANA uses double quotes like Oracle. 
    Is there any setting in SSAS that can affect this behavior?   Will HANA ever be a fully supported data source for SSAS?  If so, when?

    Hi David,
    According to your description, you are creating a SQL Server Analysis Services project, now what you want is using SAP HANA as the data source, right?
    SSAS support many type of data source. However, as you can see on the link below, SAP HANA data source was not listed on that link. So this type of data source is not supported in current version of SSAS. Microsoft will update that document when it is supported.

    Thank you for your understanding.

  • Why SAP HANA ? what made it difference from Data ware housing concept ?

    Hi,
    Greetings Guys !! I am wondering and kind of lost with giant SAP newly introduced database SAP HANA. I have been informed that HANA is developed for fast query processing mainly.The older method of query processing involves lot of time ,i.e . the request should go to database and will retrieve information . If HANA have shown IMDB ( In- Memory database ) technology , Dataware house concept also solves waiting time of query processing .
    Could some one explain me why HANA is introduced if Dateware house concept was already born ??

    Hi Venkatesh Garlapat,
    SAP HANA is/was not only about reinventing the DW concepts again, but its a lot more than that.
    Probably Google would have helped you, but let me point you to the right content which can clarify your doubts: Please refer:

  • Abap users autorization for BO BI reports (made in Design Studio) on HANA data

    Hello!
    We are bit new to BO BI and Design Studio. Cauld you help us?
    BO BI reports must represent SAP HANA data.
    We have a lot of users in ERP with their roles.
    We need accordingly restrict users access  to certain values for group of users in given Data Source based on HANA Analytic or Calculation View.
    For example, report must display only “A” Plant data for first group of users, for second group – only “B” Plant data.
    Where should we mantain users (and give them roles) and what authorization use?
    The best way for mantaining users is CUA on ERP for us.
    BO BI supports SAP authorization and role mapping with it's own user groups with no probler.
    But what about HANA? We didn't find any positive information about roles mapping and authorization in HANA.
    It looks like we need to create all users and give them roles in HANA... Is it really so? How to synchronize HANA users and their authorization with ERP after this...
    Thank you!

    Hi - this is a question that is better for the HANA space.  Do you want me to move it there?

  • How can I create geographic charts with Lumira connected to SAP HANA?

    Hello All
    I'm testing SAP Lumira and I want to make geographic charts with data from SAP HANA. This is possible when I use data from a local Excel-file. But not when I use data from SAP HANA. I was told it should work after installing Service Pack 8. But it still doesn't work. Maybe we have to turn something on, change a configuration file. Maybe it has to do with SAP Lumira, not with SAP HANA. Any help is greatly appreciated.
    Here are some technical details:
    SAP HANA Version: 1.00.81.00.392776 (NewDB100_REL).
    SAP Lumira Version: 1.19.0 (build 1099) (latest version).
    SAP HANA Studio Version: 1.00.81.0.
    Windows Version: Windows 7 Enterprise, Service Pack 1.
    Kind regards, Robbert

    Hello Antoine
    At paragraph 3.2.2 on page 73 it says:
    Creating geography hierarchies with latitude and longitude data is not currently supported for SAP HANA data sources.
    I think this explains everything. Well, almost everything. I created geographic charts with Lumira while connected with Excel or a csv-file. The question now is, am I waiting for an update of SAP Lumira or an update of SAP HANA? Or both?
    Kind regards, Robbert

  • SAP HANA on BW

    Helllo, I have a query regarding HANA roadmap. SAP is going HANA with BW on HANA and then HANA live. I do not know about side cars like what are they? If my company buys HANA live and BW on HANA, what should be our reporting strategy? like how should we distribute our reporting? should we throw everything in BW or should we keep some stuff in ECC? Currently we have CRM, SRM, ECC and BW. I need some suggestions like what other people have done. Any presentation or material will be appreciated if provided.
    Thanks.

    Yes Venkat, Majority of the Info Cubes can be eliminated in BW on HANA. Info Cubes primarily store aggregated data, which HANA is capable to calculate on-the-fly using HANA views. So you'll save space(no need to store pre-calculated aggregates), time(no load time) and effort (no InfoCube maintenance). Make the most use of HANA views and Virtual Providers.
    Side-Car means running a parallel system (a secondary second system with filtered set of data) on HANA DB for reporting purpose. Data needs to be fed in to the Side-Car HANA system and that can be done in two ways. Either as a batch job using SAP Data Services or as a near-realtime trigger based data replication using SLT.
    Check out these links. These provide more details on Side-Car approach as well as other deployment scenarios...

  • How to - Extract data from Cloud For Customer into SAP HANA system

    Hello Community,
    I have a requirement for extracting the existing data from Cloud for Customer into separate SAP HANA Box.
    Is it possible to achieve the same ? If yes, Please guide me for the same.
    Awaiting quick response.
    Regards
    Kumar

    Hi Kumar,
    In addition to what Thierry mentioned you could also use the C4C integration via standard Operational Data Provisioning (ODP) interfaces. This integration was acutally built for SAP BW and allows you to access any C4C data sources. From my perspective you can also build upon that for a native SAP HANA integration. Please also have a look at this guide: How To... load SAP Business Suite data into SAP... | SAP HANA.
    Besides that question let me also add the following: SAP Cloud for Customer already runs on SAP HANA since Nov. 2013. You may also use the powerful built-in analytics within C4C for analyzing data and any of your reporting demands. If your report should consider external data as well, you can combined the existing C4C data source with an external, so-called Cloud Data Source. More infomation is published in the C4C Analytics Guide: http://help.sap.com/saphelp_sapcloudforcustomer/en/PDF/EN-3.pdf.
    I hope this helps...
    Best regards,
    Sven

  • 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
