What is BW on HANA BW on Hana

Dear Experts,
Can you explain me the below. i have a lot of confusion in between
1.  What is BW on HANA BW on Hana.
2. Can we replace ECC data base with HANA(instead of traditional database, can we use only HANA data base?)
3. Standalone HANA
4. HANA side CAR
Thanks a lot in advance

Hi Prasad,
There is lot of documents avaialble on SCN for HANA overview.
HANA is in-memory computer platform used to handle high data volume with accelarated query performance.  HANA can be used as database as well as standalone system.
1.  What is BW on HANA BW on Hana.
     It typically means BW system will have HANA as database
2. Can we replace ECC data base with HANA(instead of traditional database, can we use only HANA data base?)
    Yes.
3. Standalone HANA & 4. HANA side CAR
    Standalone HANA reside beside your system and data is replicated into it.
You will find lot of documents on below link.

  • SAP HANA Query

    Hello, I have a query about SAP HANA. If I want to bring BSEG table in HANA from ECC but do not want to do Live update(SLT) and do not want to create all the fields that exist in BSEG in ECC one by one. what features of native HANA would I use to do that?
    Thanks.

    Hi Venkat,
    You can go with BODS or SLT.
    In BODS, you can select required fields from BSEG table in ECC and map the same to HANA table.
    You can also go with SLT, do one time load using LOAD option. Even here you can select reruired fields, not all the fields from BSEG table.

  • Hana Ado NET Multiple SELECT

    Hi everyone,
    Is it possible to get multiple result set from the only one call of HanaDataAdapter.Fill(DataSet set) method?
    What I mean, in Hana Studio I can easily excequte the following query:
    Select * From "MyDatabase"."MyTable";
    Select * From "YourDatabase"."YourTable";
    which returns multiple results.
    However, the same HanaDataAdapter.SelectCommand.CommandText will rise an Exception: Incorrect SQL syntax near ";" ...
    The same issue at HanaDataAdapter.ExcecuteReader() call.
    Is it any way to solve this problem, I need to minimize the number of queries to database.
    Best regards, Evgeny.

    Technically these are two separate SQL commands for SAP HANA Studio.
    In fact, the SAP HANA Studio parses the text in the command prompt before executing and then issues parse and execute commands for every found SQL command.
    Your requirement "to minimize the number of queries" sounds slightly "unsharp".
    Why do you want to minimize the number of queries? Could it be that you want to optimize your network traffic, instead?
    Or do you want to save on the parsing overhead?

    Han,
    You should be able to install CC on a second computer, licensing rules allow you to install on two computers.

    It has a list of the algorithms, which are pretty disappointing, I must say. No Random Forests? No ensembling methods? Given that it's using R algorithms, I must say this is a missed opportunity to beat products like SPSS and SAS at their own game. If SAP were to include this functionality, they would be the only BI vendor capable of having a serious predictive tool integrated with the rest of the platform.... but this looks pretty weak.
    I can only hope a later release will remedy this - or maybe the SDK will allow me to create what I need.
    As things stand, I could built a random forest using this tool, but I would have to use a lot of hardcoded SQL to make it happen. And if I wanted to go down that road, I could use the algorithms that come with the Microsoft/Oracle software.
    Please let me be wrong........

  • What is a dynamic join in SAP HANA?

    What is a dynamic join in SAP HANA and how it works? Please explain me with the example , how to use it?
    Message was edited by: Tom Flanagan

    Hi Sree,
    In very simple and basic terms:
    If you have table A and B with columns C1, C2, and C3 used in multi-column join (with Dynamic join set to true) from both the tables, then depending upon which columns you select in the query, ONLY those columns will be used in the join.
    For ex. if you select C1, C2 in the select statement, then the join will happen only on C1 and C2, C3 will not be used in the join criteria, even if the join definition involves all the 3 columns.

  • 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

  • What is the SQL ROWNUM equivalent in HANA SQL script

    Hi Jyothirmayi,
    ROW_NUMBER() OVER (ORDER BY <FIELD LIST>) is the function to generate row numbers.
    ORDER BY clause is mandatory to generate row numbers in HANA.

  • HANA auditing, what file types get created?

    Hello,
    I've read through the blog 'SAP HANA audit trail, best practice' by  Frank Buchholz to create audit policies in HANA. Great blog and really appreciate sharing his experience. I've also worked with my hosting team to make audit configuration changes.
    They've now asked me to check to see that the policies I've setup are creating records, and they've given me the path to check. The problem I have is I don't know what to look for. What file types are created in the OS SYSLOG by the audit policies? Would the files have the same name as the policies themselves? (self auditing, user SYSTEM, technical users, etc..) Does anyone have a sample with a screenshot to share?
    Thanks for the help.
    Cheers, Paul

    This web site may be a good place to start:

    There are other places that you may search on the Internet that may help close the gap.
    Ciao.

  • What is the best way to load 14 million COPA records from BW into HANA?

    I have been managing a project in which we are attempting to load COPA data from BW into HANA using Open Hub and we continue to run into memory allocation errors in BW. We have been able to load 350,000 records.
    Any suggestions on what the best approach would be along with BW memory parameters.
    Your replies are appreciated.
    Rob

    Hello,
    this seems to be issue in BW caused by big volume of migrated data. I do not think that this is HANA related problem. I would suggest to post this message into BW area - you might get much better support there.
    But to help as much as I can - I found this (see point 7):
    http://help.sap.com/saphelp_nw04/helpdata/en/66/76473c3502e640e10000000a114084/frameset.htm
    7. Specify the number of rows per data package for the data records to be extracted. You can use this parameter to control the maximum size of a data package, and hence also how many main memories need to be made available to structure the data package.
    Hope it helps.
