4 Why SAP BusinessObjects Explorer? SAP BusinessObjects Explorer is a search and exploration tool for unstructured and semi-structured data. Unlike querying, “exploration” is unstructured analysis. 3 A survey of 534 top BI professionals reported that the top concern was the ability to deliver faster query and data exploration capabilities. SAP BusinessObjects Explorer addresses this need. Source: Business Intelligence Survey, InformationWeek,

5 4 Why In-Memory Processing for SAP BusinessObjects Explorer? Disk speed is growing slower than all other hardware components 4 In-memory data stores Multi-channel UI, high event volume, cross- industry value chains Application- aware and intelligent data management Disk-based data storage Simple consumption of apps (fat client UI, EDI) General- purpose, application- agnostic database Architectural Drivers Improvement Addressable Memory 2502x MB/$ 0.02 MB/$ Memory 5066 x MIPS/$ 0.05 MIPS/$ CPU Technology Drivers 600 MBPS 5 MBPS Disk Data Transfer 120x 1000 x 100 Gbps 100 Mbps Network Speed x Source: 1990 numbers SAP AG 2010 numbers, Dr. Berg Physical hard drive speeds only grew by 120 times since All other hardware components grew faster.

6 Why the Rapid Adaptation of SAP BusinessObjects Explorer? One of the driving forces for Explorer has been the rapid implementation of blade solutions running on- top of SAP BW. To date, according to SAP, over 1,000 of these systems has been installed. 5

7 SAP BusinessObjects Explorer Overview You can connect in several ways to data sets: 6 Source: SAP, Aug, 2011 SAP BusinessObjects Explorer does not require SAP NetWeaver ® BW. You can accelerate all data sources. 1. External data may be indexed by the SAP BusinessObjects Data Services and stored on dedicated SAP NetWeaver BW Accelerator blades 2. SAP NetWeaver BW data may be indexed on SAP NetWeaver BW Accelerator blades for fast in- memory processing (also through HANA) 3. External data may also be accessed as “non-accelerated” via SQL/MSU universes. 4. Excel spreadsheets may also be accessed

8 SAP BusinessObjects Explorer — Big Picture BWA = SAP NetWeaver BW Accelerator

9 In-Memory Processing: Highlights — SAP NetWeaver BW Accelerator 8

10 In-Memory Processing — Creating Indexes from External Data Using the Accelerator Index Designer in SAP BusinessObjects Data Services, you can also index data from external data files and databases It is important to note that the SAP BusinessObjects indexes are on dedicated blades For SAP NetWeaver BW Accelerator you should always have one “spare” blade for failover  If a blade fails, the system can reload the indexes from the SAP NetWeaver BW Accelerator file system (i.e., GPFS) For the SAP BusinessObjects Explorer blade, you can use only one blade 9

11 SAP BusinessObjects Explorer Overview Accelerated (BWA) or non-accelerated solutions 10

12 SAP BusinessObjects Explorer - non-BW Data Using the Data Services tool, you can access non-SAP data and model it in the BWA Cube Designer tool 11 Version 4.0 Version 3.2 and 4.0

13 BO Explorer Indexing from Queries You can use BEx Queries to create complex indexes that are stored simply as a flat table in the index (de-normalized). First you must enable the query for BOEX indexing using the program: RSR_QPROV_CHECK. This checks if the query can be used for indexing Query display settings are not supported. and delta’s are not available. PS! the read mode for the query is executed as “read everything” Query display settings are not supported. and delta’s are not available. PS! the read mode for the query is executed as “read everything” Query limitations for BOEX indexing  Technical name cannot be over 20 characters  Query cannot have 2 structures  Query cannot use local aggregation or calculations before aggregation  Integrated planning queries and queries with input variables cannot be used  Queries with temporal hierarchy joins cannot be used

14 The Many SAP BusinessObjects Explorer Access Methods SAP BusinessObjects Explorer is normally accessed through a browser However, you can always download the results from a search into Excel and perform analysis from there You can save the result set as an image and load it on portal sites, handhelds, or send as Finally, you can access the SAP BusinessObjects Explorer directly from a handheld device that supports basic Web browser functions Source: Dan Kearnan, SAP AG (2010)

15 What We’ll Cover … SAP BusinessObjects Explorer overview Understanding ad hoc search A step-by-step demo of analysis and formatting Installing and managing SAP BusinessObjects Explorer Planning and budgeting for SAP BusinessObjects Explorer Some features of version 4.0 Wrap-up 14

16 Ad Hoc Search The core idea of SAP BusinessObjects Explorer is that users can search the BI data like they would using Google, Yahoo, Bing, or other search engines Users should not have to know how the data is structured, what query to execute, or how to display the data SAP BusinessObjects Explorer takes a “first stab” at presenting the data in a usable format  From there, users may navigate and change the display The users may save their settings and the display at any time 15

17 Ad Hoc Search Example 1. First we searched on “sales” and found three possible choices 2. We selected “sales Information” and searched after the term "Texas” This shows the sales amount by state as a table, the gross margin as a graph and as a table Any display can be exported to Excel, saved as an image, ed, or bookmarked

18 What We’ll Cover … SAP BusinessObjects Explorer overview Understanding ad hoc search A step-by-step demo of analysis and formatting Installing and managing SAP BusinessObjects Explorer Planning and budgeting for SAP BusinessObjects Explorer Some features of version 4.0 Wrap-up 17

19 A Step-by-Step Demo: Searching Step 1. We load the SAP BusinessObjects Explorer Web interface into a browser Step 2. We Search for “sales” Step 3. We get the search results and a list of “information spaces” The search result list is sorted based on an internal “relevancy” score. 18

20 A Step-by-Step Demo: The Initial View Step 4. The system looks at the data and formats it based on implied hierarchies (i.e., time, geography, customer) as well as measures. Users may navigate and change measures, graphs, and tables.

21 A Step-by-Step Demo: Searching in a Result Set and Measures Step 5. Again, we are interested in sales around Texas, and can search the initial result set Step 6. By changing the Measure from “margin” to “sales revenue” all graphs and tables change 20

22 A Step-by-Step Demo: Changing Charts and Drill Down Step 7. We can change the chart by selecting from the left menu options Step 8. While the first display was based on the “best guess,” we can now drill down to the different product lines The best graphing options, based on our data, is highlighted by a star: 21

23 A Step-by-Step Demo: More Graphing Options Step 9. There are many graphing options and some are more useful than others “Proportional” view is best when you are looking for size relations, i.e., what are the largest contributors to sales? Try several graphing options before deciding on “your” view. Most of the time, the reccomended graphs works best for the data set, but not always 22

24 A Step-by-Step Demo: Explore More — Filtering Step 10. By clicking on “Explore more” you are promted to filter on the characteristic you selected Filtering data makes the images more meaningful. It is harder to analyze 50 states and scroll through the data. Since we clicked “Explore more” in the state box, we can now select only the states we are interested in 23

25 A Step-by-Step Demo: Filter Results We now see the (product) lines are sold in only three states Always see if any items have been removed in a filter before you look at the data, i.e., 15,061,789 is not the sales revenue for the firm, only the revenue for three states. Filter values are displayed here: 24

26 A Step-by-Step Demo: The Visualization Panel Step 11. You can also zoom in on the data by only showing the visualization panel In the Visualization Panel, you can view all the fields and measures as a complete table Notice: The table only contains data from the three states we filtered on

27 A Step-by-Step Demo: Top 10 Analysis Step 12. In the visualization panel, we can perform top 10 analysis by a single click. All other values are summarized in an “other” category and graphed. The ability to quickly group and summarize data is a great feature. This is normally done in the BI analytical engine of SAP NetWeaver ® BW, and can be very slow. 26

28 A Step-by-Step Demo: Other Display Options Step 13. You can view the data in relative size by using a comparison graph Line graphs are usually preferred if you have 3-20 data points Areas on the graphs can be highlighted by clicking on one or more data points

29 A Step-by-Step Demo: Sorting and New Calculations Step 14. Any data panel can be sorted in many ways Measures used on any graph can be calculated “on-the-fly.” Step 15. We can also add our own measures In our example we are adding the measure “Margin Per Unit” as total margin divided by “quantity sold” 28

30 A Step-by-Step Demo: Mini-OLAP Example Step 16. In this mini-OLAP example we are:  Looking at some key cities in a few states (filter)  Only looking at data for 2003 and only for “Sweats and T-Shirts” (filters)  Examining the profit margin per unit sold (customized calculation) SAP BusinessObjects Explorer is not an OLAP tool, but can support basic drill-down features, and thereby complex unstructured analysis. 29

31 A Step-by-Step Demo: Downloading a Data Set Step 17. Any result set displayed in SAP BusinessObjects Explorer may be saved to a PC as a comma-delimited file You can select to save the data set filtered by the navigations or only the data from the visualization panel Data saved this way can be opened in Excel or imported directly into Access and other databases. 30

32 A Step-by-Step Demo: Configuring Measures Step 18. Measures in the data set can also be configured to be “filter columns” for user navigation Other options include  Max  Min  Sum  Average This is how you determine how data will be accessed and how measures will be displayed. 31

33 HINT: Connectivity, Network, and Non-Logical Calculations You sometimes can get the following message from the system: This normally means that the connectively to the system is either too slow, or broken. This is an issue that is more common for very slow connections such as older Wi-Fi networks. You can also get this error message if the result set you requested is not available (i.e., non-logical calculations) 32

34 Some Limitations – Authorizations and MultiProviders When you create the index, the conversions, hierarchies, texts and authorization indexes are made. However, if the Analysis Authorizations are on the MultiProviders, they cannot be used in the index.  You can fix this by placing the Analysis Authorizations on the basic cubes instead. PS! When creating snapshots, you can only filter on a single characteristic and MPSI is not available for BW ‘reporting’ (see other limitations in note: ) PS! When creating snapshots, you can only filter on a single characteristic and MPSI is not available for BW ‘reporting’ (see other limitations in note: )  When you create an index on a MultiProviders, a part provider can be used. This creates a single index for BWA and BOEX, but part providers can only be consumed by BOEX (not BW) [see note: ]  BOEX Index snapshots can be taken of a MultiProviders (MPSI), however, this can take a long time to create if the data volume is large. Delta capabilities can be done in a different rollup step (RSDDTPS_INDEX_MPRO).

35 Some Ideas – Authorizations If you use Authorization based on hierarchy nodes ( 0TCTAUTHH), it is not used by BOEX. Also, if you have based your authorization on custom user exit coding, BOEX cannot leverage this either. Hint: Create an Active Directory group and add all users to this group. Since BOEX does not use SAP security, you can use the AD group for Single-Sign-On. To setup the security in RSDDTPS_AUTH, try the following: Source logic from: M. Umarwadia and M. Walsh, SAP TechEd 2011

39 SAP BusinessObjects Explorer and SAP BusinessObjects Explorer Blade Features Many customers looked at earlier releases of SAP BusinessObjects Explorer and the previous release called “Polestar” and noted several limitations Many of these limitations are now remedied. These include:  The possibility to import your own Excel files  Create your own calculations at the user level  You can group related dimensions for simplicity of analysis  Security in improved and row-level data security can be implemented  You can personalize the view by filtering information  Users may navigate hierarchies instead of “flat” data PS! Currently the SAP BusinessObjects Explorer solution is licensed based on number of blades and the number of named users.

40 SAP NetWeaver BW Accelerator 7.2 Features In earlier released of SAP NetWeaver BW Accelerator you could not index DSOs, with version 7.2 this is now available Also, prior to SAP NetWeaver BW Accelerator 7.2, the solution was only used for rapid in-memory data fetches  BI analytical engine processes such as data sorts, calculated key figures (CKF), restrictive key figures (RKF), top-5 conditioning, etc., were still costly overheads to the query execution We now have a new “calculation engine” and a new “aggregation engine” inside  This means that the benefits of in-memory processing is no longer confined to data fetches and queries can be made to run even faster You can now performance tune some BI Analytical Engine functions with SAP NetWeaver BW Accelerator, not only data reads. PS! HANA can also support BOEX You can now performance tune some BI Analytical Engine functions with SAP NetWeaver BW Accelerator, not only data reads. PS! HANA can also support BOEX 39 Source: SAP AG, Nov. 2011

42 SAP BusinessObjects Explorer Milestone Plan Since most vendors build the HW as Made-to-Order, it is important to get the purchase order placed as soon as possible. 41

43 Budgeting for SAP BusinessObjects Explorer on BWA You have to plan for:  SAP BusinessObjects Explorer licenses (per blade as well as per number of users)  Hardware costs (approx. $14K-$20K per chassis + $6-12K per blade and a rack, if you do not have a spare place for the chassis. Add in two network cards and a file system.)  Good planning numbers for production environment (only):  Small HW costs ~ $40K to $60K  Medium HW costs ~ $60K to $250K  Large HW costs ~ $250K to $500K  Add consulting fees for 2-3 people for 8-12 weeks. The actual time needed depends on how much of the infrastructure you already have in-place and how you plan on rolling out the solution) Remember to plan for three years of vendor service costs. 42
