11 Business Intelligence Green Fields Common Risks No common terminology, will only know SAP terms What is the meaning of report, BI, dashboards Dimension vs. Characteristic Measure vs. Key Figure No prior experience with BI tools Hard to get beyond operational/regulatory reporting Lots of customer education required, lack of product knowledge Clarification of key business intelligence concepts are likely to be necessary Tendency to put the data source central, rather than the end user report Expectation that Web Intelligence should replace BEx Analyzer Lack of product knowledge Misunderstanding of product portfolio and roadmap SAP doesn t dictate moving all your analysts off BEx Analyzer at all Web Intelligence is not an OLAP interface Confusion of intended audience Assumption we just connect up to existing BEx Queries Product may not support all elements of the existing BEx queries well Violates the BI principle of working backwards from report requirements BEx queries need to be purpose-built, tuned, and potentially aggregation added 2010 SAP AG. All rights reserved. / Page 11

12 Business Intelligence Green Fields Common Risks Minimize movement of data especially for workflows that use MDX access to BW Avoid client side filtering push that down to the BEx query level where possible MDX Overhead Increases as The Number of Cells Increase 2010 SAP AG. All rights reserved. / Page 12

13 Best Practices for BEx Query Design Overall recommendation BI Queries are recommended as data sources for SAP BusinessObjects BI Tools BI Queries offer a flexible extension to the data modeling environment and require less effort to change than InfoProviders BI Queries offer significant functionality to create customized data sources that meet enduser requirements, such as Calculated Key figures, Restricted Key figures and SAP Variables. You do NOT need a BI Query for every report Focus the implementation strategy on limiting the number of BI Queries that share common elements Build a small set of BEx queries focusing on sharing common elements The BI Client tool and report definition is the primary influence factor on how much data is being retrieve from SAP NetWeaver BW In some situations extremely large queries and universes can adversely affect performance 2010 SAP AG. All rights reserved. / Page 13

14 Best Practices for BEx Query Design Placement of Characteristics / Key Figures - no direct impact on generation of Crystal Reports reports Allow External Access option should be set in the properties of the BEx query For large sets of key figures, use option - Use Selection of Structure Members Leverage the capabilities of the Restricted Key and Calculated Key Figures where possible As part of the underlying BI query, they will be processed by the BW back end Can be shared across queries, minimizing development downstream Leverage SAP Variables as part of the BW Query Can be shared across queries, minimizing development downstream List of Values are being generated automatically Time based structures / calculations Leverage EXIT Variables as part of the BW query Data Level Security & BW Use BW authorizations for data level security 2010 SAP AG. All rights reserved. / Page 14

15 Best Practices for BEx Query Design SAP NetWeaver BW Query vs. InfoProvider BI metadata feature Characteristics (incl. Time and Unit) Hierarchies Basic Key Figures Navigational Attributes Display Attributes Calculated Key Figures / Formulas Restricted Key Figures Custom Structures Variables SAP OLAP BAPI support level InfoCube/BI Query InfoCube/BI Query InfoCube/BI Query BI Query only InfoCube/BI Query BI Query only BI Query only BI Query only BI Query only 2010 SAP AG. All rights reserved. / Page 15

16 Good Tuning, Configuring & Best Practices Common Across All Tools Building High Performance BI Reports Design reports to fetch smaller sections of data by breaking it in smaller parts The report can be partitioned using filters on calendar dates or segments on a dimension SAP BEx Query as entry point in a one (BEx query) to many (reports / universes) relationship Customers can leverage their existing investment with SAP BusinessObjects BI Tools Push work down the stack as much as possible 2010 SAP AG. All rights reserved. / Page 16

17 Good Tuning, Configuring & Best Practices Crystal Reports Crystal Reports is able to connect to SAP NetWeaver BW and SAP ERP Crystal Reports provides you the options to leverage SAP ERP or SAP BW or even combine those Crystal Reports is able to leverage a parent child relationship for external hierarchies In case the hierarchy is changing there is no need to re-design the report Integration of Crystal Reports into SAP NetWeaver BW Translation and Transport Mechanism You can leverage common SAP NetWeaver mechanism to globalize and administrate your Crystal Reports based content 2010 SAP AG. All rights reserved. / Page 17

18 Good Tuning, Configuring & Best Practices Xcelsius Xcelsius is providing several choices for data connectivity to SAP ERP and SAP BW (Live Office, Query as a Web Service, Direct SAP NW BW connectivity) Customers can leverage live or pre-scheduled reports with SAP ERP and SAP NetWeaver BW Direct connectivity for SAP NetWeaver BW does support BEx Query Conditions and Display Settings Xcelsius is able to leverage more of the underlying BEx query compared to Crystal Reports and Web Intelligence Integration of Xcelsius into SAP NetWeaver BW Translation and Transport Mechanism You can leverage common SAP NetWeaver mechanism to globalize and administrate your Xcelsius content 2010 SAP AG. All rights reserved. / Page 18

19 Good Tuning, Configuring & Best Practices Web Intelligence OLAP Objects not inserted in Web Intelligence query don t have direct impact on the query Only use needed objects; results in leaner MDX that performs better (< XI 3.1 SP3) Starting with Service Pack 03 make use of Query Stripping Retrieving large List of Values (LOV) can result in prompts taking more than a few seconds Improve prompt loading by using optional prompts Use Delegated search to limit the data loaded in prompt LOV Minimize data fetch during report refresh by using Guided Navigation Use Drill and Report Linking in Web Intelligence reports Store Scheduled Report Instances for large and long running reports Scheduled instances effectively cache data in the report, improving open and filter performance. Characteristics filtered in Web Intelligence reports should be filtered on indexed values Filtering on indexed values avoids the need to resolve member captions to member unique names, boosting performance 2010 SAP AG. All rights reserved. / Page 19

20 Good Tuning, Configuring & Best Practices Web Intelligence Leverage Query Stripping with Service Pack 03 The query issued by Web Intelligence to the OLAP universe will only request the information rendered/presented to the user on the report Reporting against Large Data Set with Master Data Columns: re-factor query into multiple sub-queries Separating constant Master data from details records improves query performance 2010 SAP AG.

21 The Bad Requires a Workaround Common Across All Tools Except Analysis none of the SAP BusinessObjects BI Client tools in the XI 3.1 release do support Exceptions defined in the BEx Query Each of the BI client tools is providing you with similar functionality Except Analysis and Xcelsius none of the SAP BusinessObjects BI Client tools in the XI 3.1 release do support Display Settings defined in the BEx Query, such as scaling factors or number of decimals Each of the BI client tools is providing you with similar functionality Except Analysis none of the SAP BusinessObjects BI Client tools in the XI 3.1 release allow a selection of elements from a custom structure Selection can only be done based on descriptions not based on technical names 2010 SAP AG. All rights reserved. / Page 21

22 The Bad Requires a Workaround Crystal Reports Custom Structures are represented as single fields without the actual technical names for the structure elements The structure is available but you can not select specific elements of a structure List of values for variables / parameters are static in Crystal Reports Designer Values are dynamic in InfoView remember that Crystal Reports Designer is a Design environment (do you really need all members?) 2010 SAP AG. All rights reserved. / Page 22

23 The Bad Requires a Workaround Xcelsius Xcelsius is offering hierarchies as part of the direct SAP NetWeaver BI connectivity but there is no hierarchical visualization component available out-of-the-box There are hierarchical visualization offered by several partners on SAP EcoHub Xcelsius dashboards using the direct SAP NetWeaver BI connectivity will NOT work hosted in the BusinessObjects Enterprise system (as of Xcelsius 2008 SP2) Xcelsius dashboards using the direct SAP NetWeaver BI connectivity need to be hosted inside of SAP NW BW SAP AG. All rights reserved. / Page 23

24 The Bad Requires a Workaround Web Intelligence Custom Structures are represented as single fields without the actual technical names for the structure elements The structure is available but you can not select specific elements of a structure Keyfigure of type TIMS (time) are not properly supported to reflect the data type You can leverage the Formatted Value or use formulas in the Web Intelligence report Scheduling a Web Intelligence report does not provide the option to enter user and password You can configure server side trust using SNC 2010 SAP AG. All rights reserved. / Page 24

25 The Ugly No Workaround availaible Common Across All Tools Except Analysis and Xcelsius none of the SAP BusinessObjects BI Client tools in the XI 3.1 release do support Conditions defined in the BEx Query No real workaround possible. Results in all the data being transferred to the client tool Except Analysis none of the SAP BusinessObjects BI Client tools in the XI 3.1 release do support the option to create a report based on master data (vs. data in the InfoProvider) No real workaround possible. Only data available in the InfoProvider is shown SAP AG. All rights reserved. / Page 25

26 The Ugly No Workaround availaible Crystal Reports Manually created filters or parameters are not passed down to the server, instead they become client side filters / parameters Instead of manual filters or parameters make use of variables in the BW query Crystal Reports 2008 is always using NON EMPTY, means reports based on master data (e.g. Balance sheet based on complete hierarchy) are not possible No real workaround possible Only a single Keydate variable per BW query is supported No real workaround possible. Your query needs to leverage one single / global keydate Hierarchy Node variables are shown as flat list in Crystal Reports Designer No real workaround possible. Remember that Crystal Reports Designer only shows the values for the default hierarchy 2010 SAP AG. All rights reserved. / Page 26

27 The Ugly No Workaround available Xcelsius Xcelisus dashboards based on the direct SAP NetWeaver BW connectivity can not be launched from SAP BusinessObjects InfoView Xcelsius dashboards using direct SAP NetWeaver BW connectivity need to be stored and launched from SAP NetWeaver BW 2010 SAP AG. All rights reserved. / Page 27

28 The Ugly No Workaround available Web Intelligence Avoid Building large Web Intelligence reports (large in size) Documents over 200 MB in size can impact the performance Optimal size should be between 5 to 10 MB Web Intelligence is always using NON EMPTY, means reports based on master data (e.g. Balance sheet based on complete hierarchy) are not possible No real workaround possible Web Intelligence supports only a single Keydate variable per BW query / Universe No real workaround possible. Your query needs to leverage one single / global keydate Universe Designer does not support time dependent meta-data No workaround possible. Universe Designer will leverage the system date Default Values for Variables are used, even when explicitly removed from the list of values No workaround possible Recommendation is to remove the default value from the variable 2010 SAP AG.
