BW 7.3 Upgrade - why and How t0

SAP NetWeaver BW 7.3: If, When, and How to UpgradeDr. Bjarne BergCOMERIT 2012 Wellesley Information Services. All rights reserved.In This Session In this session, well take a look at the major new features of SAP NetWeaver BW 7.3Well also examine the new upgrade tools and take a step-by-step look at what is required to upgrade an SAP NetWeaver BW system to version 7.3Finally, well look at an example of how to minimize upgrade risks while also changing the hardware during the upgrade

1Worth Pondering: System complexity is increasing, while attention spans are decreasing

SAP NetWeaver BW 7.3 Release History and TestingSeven customers and nine service partners participated in the beta testing. The beta testing ended in two years ago with the following scores:

SAP NetWeaver BW 7.3 was tested extensively in a beta program and in ramp-up for almost one year!1234

4Ease of Installation and Upgrade Wizards and the ASU ToolboxA major new feature of SAP NetWeaver BW is the ability to use a Wizard to install the system

You can choose to use both a Java and/or an ABAP stack when installing 7.3

This includes the following Wizard templates: ABAP Stack initial setup Connectivity initial setup Templates for automated configuration Business Suite-7 integration Technical content reports for Initial Setup Upgrade step-by-step (SAP Note 1000009)5NEW: Specific Database Support TeradataSAP NetWeaver BW 7.3 can now run on top of the Teradata database, including:The ability to use SAP NetWeaver BW Accelerator on top of Teradata The use of SAPs system to manage transports between environments6NEW: Specific Database Support IBM DB2 SAP NetWeaver BW 7.3 supports specific database features:DB2 v9.5 supports PSA, DSO, and fact table compressions for reduced disk volume (integrates with DB2 storage management)Support for MDC clustering in the DB CockpitThis is available in v9.5.2. or higher and default for all DSO tables and PSA in version 9.7Much faster request deletion if MDC clustering is usedDB2 v9.7 supports Index compressions for reduced disk volumeSupport for IBM DB2s Database Partitioning Feature (DPF)

In the past, SAP NetWeaver BW has been unable to take advantage of vendor-specific database features. This has changed, and workarounds are needed less frequently.

Solution Manager has been updated to take advantage of these new monitors

9New 7.3 Performance and Admin Monitoring Capabilities (cont.)Other new monitors include:DEAMON update information (i.e., RDA capacity status, usage)A performance monitoring workbench for performance trendsProcess chain monitoring (new transaction: RSPCM) with error and active chain monitoring, user-specific displays, and performance threshold monitoring (i.e., for SLAs)

10NLS: In SAP NetWeaver BW 7.3, the Near Line Storage has been enhanced to include archiving, support for write optimized DSOs, and database support for tools such as DB2 Viper (v9.5) and more

11Semantic Partitioned Objects (SPO)When data stores and InfoCubes are allowed to grow over time, the data load and query performance suffersNormally objects should be physically partitioned when the numbers of records exceed 100 millionHowever, this may be different depending on the size of your hardware and the type of database you useIn SAP NetWeaver BW 7.3 we get an option to create a Semantic Partitioned Object (SPO) through wizardsYou can partition based on fields such as calendar year, region, country, etc.

12Semantic Partitioned Objects (SPO) (cont.)When an SPO is created, a reference structure keeps track of the partitions. The structure is placed in the MultiProvider for querying.

SPO Wizards create all Data Transfer Processes (DTP), transformations, filters for each data store, and a process chain automatically.

The New HybridProvider and Real-Time DataThe HybridProvider (HP) is new in SAP NetWeaver BW 7.3. The core idea is to link the historical data inside BW with real-time data. There are two ways of implementing an HP:HP based on a DSOHP based on a Virtual InfoCube

This solution provides for really fast queries, but delta logic has to be custom designedOption 1: The DSO-Based HybridProviderCore features:Real-time data is in the DSO and historical data in the SAP NetWeaver BW Accelerator-based InfoCubeThe DSO use real-time data acquisition (RDA) to load dataSAP NetWeaver BW automatically creates a process chain for the HybridProvders data flowThe process chain is executed for every closed request

This is a good option if you have a low volume of new records and a high number of queries or operational dashboardsOption 1: The DSO-Based HybridProvider (cont.)This solution provides for really fast queries, but delta logic has to be custom designed and may be complex. However, the solution allows for high-frequency updates and very rapid query response.

17Virtual cubes with many users may place high stress on the ERP systemOption 2: The Virtual Cube-Based HybridProviderCore features:Data is read in real-time from SAP ECC, while historical data is read from SAP NetWeaver BW AcceleratorThe difference depends on how often SAP NetWeaver BW Accelerator is loaded Non-complex data logic can be appliedDTP is permitted if you do not filter the data set
