    About this DocumentBusiness Case

    This document is based on Sales Business case scenarios.

    Purpose

    This manual aims to help you to understand the modeling of HANA views into BW and reporting based on

    BW providers in SAP BW on HANA. This kind of processing is done in SAP BW on HANA. This manual also

    provides details of the steps involved in creating and modeling HANA views and migrating to BW and creating

    a report based BW providers. This document is created solely with the intention of sharing information.

    Pre-requisites

    Following are the pre-requisites for performing the tasks presented in this manual:

    SAP BW on HANA 7.4 installed on the server with packages sp4 (SAPKW74004). SAP BW on HANA 7.3.1 installed on the server with packages sp9 (SAPKW73109). SAP BW on HANA 7.3 installed on the server with packages sp10 (SAPKW73010). HANA database upgraded to version HANA SPS 06 and above. BW authorization and Analytic privileges. Knowledge of BO Objects. Knowledge of BO Data services.

    1 Overview of Transient provider, Virtual provider and Composite provider in BW 7.4

    DSO and InfoCube in BW 7.4 are HANA-Optimized by default. This reduces the activation time and has a

    huge impact on the performance .Similarly modeling HANA Views in BW on HANA into Transient providers,

    Composite Providers and Virtual Providers also has a huge impact on performance if the underlying database

    is HANA.

    1.1 Transient Provider

    Key features

    Its metadata in BW is not persisted, but always generated at runtime. BEx Queries built on top can adapt to changes automatically as far as possible. Navigational attributes of an assigned Info Object cant be used .

    It cannot be used in Multi provider. It can only be used in Composite Provider in order to merge with other InfoProvider. It is exposed to BEx and BI tools.

    1.2 Composite Provider

    Its biggest advantage that it performs both union and joins operation which overcomes the limitationof Info Sets and Multi provider in BW .

    1.3 Virtual Provider

    Key features

    It offers a very flexible way of integrating data not stored in BW Objects into the consistent BW world. We can turn on Navigational Attributes for the Virtual Provider as usual. Then we can

    map the Navigational Attribute also to a field in the HANA model in the Provider specific

    properties if you do not map it, the data comes from the Master data tables in BW.

    Virtual Provider can be transported as usual, it can be used in a Multi Provider and BEx Queries canbe built on top, just like for any other Virtual Provider.

    The data read access at Query runtime is not via SQL, but it uses the same special Analytics APIthat we use to access data in InfoCubes, DSOs, and Multi Providers. This enables the BW Analytic

    Manager to push down operations to HANA instead of performing them in the application server.

    2 Source Data Extraction (using BO Data

    Services)

    We will now see the basic feature of Extraction and Loading from Flat file system to HANA using BO Data

    Services.

    Log in to BO Data Services with proper username and password.

    We create new Excel type format to load Sales Item data (VBAP Table).

    Next we also mapped the fields in Query transform.

    We run a batch job by right clicking it. Next we see the data in the template table and import the table by right clicking it.

    3 Source Data Extraction (LO Extraction)

    We will now see the basic feature of Extraction for Sales Header data from EC6 system.

    Log in to EC6 with proper username and password.

    We will activate the data sources using a transaction code RSA5.

    Next we have to fill up the set up tables for the data sources. For doing this first we need to deletethe contents that are already present in that setup tables.

    Go to the transaction code LBWG and select the application component whose content has to bedeleted.

    To check whether the setup table is deleted or not go to the transaction code RSA3 and give the data

    source name and it will show Record 0 found which means data has been deleted from the setuptable.

    Now using the transaction code LBWQ delete the extraction queue of the data source. Also delete the delta queue for the data sources using the transaction code RSA7. Next is to fill the setup table using the transaction code SBIW or OLI*BW where * denotes the

    application component
