Why Upgrade – end of support… de: upgra for ason !” #1 re had to se I Becau “ Many upgrades are driven by end of support for a certain release. SAP has now created a 5 -1 -2 maintenance system that consists of: - mainstream maintenance - extended maintenance 3

The 5 -1 -2 maintenance strategy Going forward, SAP will provide five years of mainstream (standard) maintenance, with the option to extend their maintenance coverage for a period of up to three years for small premiums over the standard maintenance rate. 1. Five years of mainstream maintenance at the standard maintenance fee 2. One year of extended maintenance at an additional two percent maintenance fee* 3. Two more years of extended maintenance at an additional four percent maintenance fee per year*. After these eight years, customerspecific maintenance begins, providing a program of support and services uniquely tailored to individual customer requirements. The plan covers SAP solutions based on the SAP Net. Weaver platform including my. SAP SCM, SRM, PLM, CRM, and industry add-ons. *check with your account executive to see what your fee may be 4

The Bigger Picture – Net. Weaver ? ? Net. Weaver is a set of solution components that provides a comprehensive architecture. All components of Net. Weaver can use the same operating system release, and the same database release. All components can be run within a single physical server if it is a small configuration, thereby reducing the management of many systems & databases 5

Why Upgrade to NW BI 7. x? One of the major reasons for upgrading your BW environment is the availability of new content and features in the next release. Let us take a look at some of the major new features of version BI 7. x: Web Application Designer BI Accelerator BEx Broadcaster BEx Query Designer BEx Report Designer Re. Modeling Toolbox Security Changes New ETL Interface BPS Integrated Planning PDF print Real-time data warehousing BEx Web Analyzer We will now take a quick look at these features 6

Web Application Designer is improved The Web Application Designer is improved with new chart types (Heat Map, GANTT & Milestone Trend Analysis), as well as new layout elements such as ‘tab strips’. WAD also has new step-by-step wizards for maps, command editing to create Web API Commands and charts, as well as a simplified wizard for layout elements such as radio buttons, action buttons etc. This reduce the amount of custom coding required with the help of Command wizards, Auto complete and WAD is a key tool for all SAP BI shops and in BI 7. x the tool is simplified and more powerful. New: Integration with NW BI 7. x BEx Report 7 Designer.

Why upgrade? - BI Accelerator for BI 7. x SAP BW Any tool The SAP BI accelerator makes query response time 50 -10, 000 faster. You use process chains to maintain the HPA engine after HP, Sun and IBM have each data load standard solutions ranging from $32 K to $250 K+ that can be installed and tested in as little as 2 -4 weeks (+ SAP license fees) Breaking news: Blades with 32 Gb are now certified by SAP (July 2008) 8

New Broadcaster features of BI 7. x New Object Types You can broadcast BEx query views and formatted reports (“reports”) in addition to Web applications, queries and workbooks. Reports are a new BEx object type developed within the new BEx Report Designer tool. New Output Formats New output formats are based on the distribution type you select. But, you now can broadcast web documents as PDF files. 9

New Broadcaster features of BI 7. x New Distribution Types You can broadcast to any printer using Adobe’s PDF, Printer Common Language (psl) or Post Script (ps). (hint: Set up the printers under tools CCMS print). You to broadcast user-specific information based on attributes in the master data attributes using a distribution list in BI (bursting of emails). The information can be controlled by the system so that users only see data related to them. 10

New Broadcaster Features of BI 7. x (cont. ) Exception broadcasting is now available in the Broadcaster. Create the exceptions in the query designer and select distribution type in the broadcaster. You can also use additional distributions types (subordinate) and create rules for when the exception report is “monitored”/ executed. Exceptions can be based on single events or levels of any performance measure. NOTE: To manage all alerts and workflow tasks from a single location, an alert is integrated with the portal’s universal worklist in the “central alert framework” of NW application server. You can use multiple distribution types to create a setting that broadcasts over many channels (e. g. , the printer and the portal). 11

New Broadcaster Features of BI 7. x (cont. ) To increase the performance of key queries, you can fill the OLAP Cache, or the MDX Cache. This is useful if you have large numbers of users accessing a query, or you have a query that accesses a high volume of data. The Fill Precalculation Store distribution type allows you to precalculate Web templates, and the Precalculate Value Set option allows you to fill precalculated value set variables with values for characteristic values. The precalculated value sets are then available as variable values in BEx queries. Old Reporting Agent scenarios still run in Net. Weaver BI 7. x. However, the Reporting Agent will not be developed any further and is removed from the BI 7. x Workbench. You can now only reach the Reporting Agent using transaction code REPORTING_AGENT 12

BEx Query Designer gets a ‘facelift’ The 3. 5 x BEx Query Designer You can choose if you want the old or the new look after the upgrade This new property pane makes it easier to format and control displays than in the past. The BI 7. x BEx Query Designer Note: 13

Why upgrade? - BEx Report Designer This new 7. x tool was created to simplify the formatting of reports and fix many of the printing issues in previous versions of BW. We now get color control, headerfooter control and many new features such as location control of cells and integration of pictures, charts and fixed text. Source: SAP AG, 2008 For many, this tool may reduce the need for 3 rd party tools to address structured reports. 14

Why upgrade? – The Remodeling Tool Box In BI 7. x you get a new tool to add characteristics and key figures to your model. In older BW versions, if you forgot to include a field in your infocube , the rework was quite substantial and often involved reloading the In the first releases of BI 7, infocube as well. you could not transport the new models, now you can. You can also: Remove, exchange, replace, add & fill dimension characteristics and key figures. NOTE: during (dictionarybased) conversion process, queries are not possible; aggregates will be automatically deactivated and must be rebuilt afterwards Source: SAP AG, Richard Brown, Aug. 2008 NW BI 7. x goes a long way to address the complaints that BW is a hard to maintain environment with ‘forever’ fixed models. 15

Why upgrade? - Better security features There are many new security features in NW BI 7. x, and a conversion is needed (all or nothing). Role menus are displayed in the portal and passwords becomes case sensitive. If you want to have downwards compatibility with old passwords set the parameter login/password_downwards_compatibility >= 3 (SAP Notes 862989 & 1023437) Authorizations are fundamental building blocks of the new reporting concept and security contains both the data value and hierarchy restrictions. The new security can be built using new “RSECADMIN” transaction 16 Source: SAP AG

Why upgrade? - More Authorization Objects Authorization objects for the Data Warehousing Workbench: S_RS_DS: For the Data. Source or its sub objects (BI 7. x) S_RS_ISNEW: For new Info. Sources or their sub objects (NW BI 7. x) S_RS_DTP: For the data transfer process and its sub objects S_RS_TR: For transformation rules and their sub objects S_RS_CTT: For currency translation types S_RS_UOM: For quantity conversion types S_RS_THJT: For key date derivation types S_RS_PLENQ: Authorizations for maintaining or displaying the lock settings S_RS_RST: Authorization object for the RS trace tool S_RS_PC: For process chains S_RS_OHDEST: Open Hub Destination You get the ability to use much lower security Authorization objects for the Business Explorer: granularity for S_RS_DAS: For Data Access Services developers and users!! S_RS_BTMP: For BEx Web templates S_RS_BEXTX: Authorizations for the maintenance of BEx texts Authorization objects for the Admin of analysis authorizations S_RSEC: Authorization for assignment and administration of analysis authorizations S_RS_AUTH: Authorization object to include analysis authorizations in roles Changed Authorization Objects: S_RS_ADMWB (Data Warehousing Workbench: Objects): New sub objects: CONT_ACT – Installing Business Content; USE_DND - Drag & Drop to Info. Areas and application components; CNG_RUN - Attribute change run Source: SAP AG July 2008 17

Upgrading to BI 7. x Security SAP has created an ABAP migration tool in SA 38 (RSEC_MIGRATION) to help you upgrade security in NW BI 7. x. Customer exit variables for the object 0 TCTAUTHH does not migrate, and you will have to manually reassign all hierarchy nodes. New BI authorizations are set in SPRO (maintained in RSECADMIN). After technical upgrade, you can select new Concept (Notes: 820183 & 923176) If you used an authorization concept in SAP BW 3. x, switch back to “Obsolete Concept with RSR Authorization Objects”. 18

Why Upgrade? – Better ETL Design (conversion needed) NW BI 7. 0 has a new transformation concept that replaces transfer and update rules. Migration to new data flow is not mandatory, but assistance is available for several key objects. A migration the complete data flow will require a significant effort. To do so, convert the Data. Sources and the Persistent Staging Area to the new DTP process, follow SAP Note 906789. To test the conversion of the Data. Sources you should also run: 1. RSSM_CREATE_REQDONE_FROM_SEL 2. RSSM_HASH_ENTRIES_CREATE for all requests 3. RSSTATMAN_CHECK_CONVERT_DTA 4. RSSTATMAN_CHECK_CONVERT_PSA More work: To redefine BI Statistics, see notes 934848 & 964418. Also, use SM 37 in production to find any other jobs that are scheduled, and make sure they are also tested 19

Some upgrade hints A step-by-step approach to moving to new data flow architecture usually makes the most sense. Identify key data flow scenarios and plan migration for those first. Existing data flow scenarios are unchanged after the technical upgrade BI 7. 0 objects use background processes and 3. x objects use dialog processes The objects can co-exist but can potentially cause problems with batch windows and performance optimization Data. Source “emulation” allows mixed mode. It provides 3. x Data. Sources in the form of new runtime objects in 7. x Data. Source “migration” is optional 20

Why upgrade? - BPS Integrated Planning (still supported) 1 Info. Provider 2 3 4 Aggregation Level Filter Planning Function 5 Planning Sequence 6 Pattern You can now create planning templates using the web based planning wizard to create models using patterns in the data (tool: “Road map Pattern”). Queries based on aggregation levels can now also write back to the Info. Provider 21 Source: SAP AG, 2008

Why upgrade? –PDF Print You can also use the PDF to create reports based on BEx web applications, queries and reports using the Adobe DS (comes with BI 7. x). The PDF options allows companies to protect reports from changes by employees by taking a ‘snapshot’ of the data regardless of subsequent updates to the data warehouse. Risks: no link back to SAP BW is needed and security is not The only Gotchas. . Your users now need to install Acrobat Reader (free at http: //www. adobe. com/ products/acrobat/readstep 2. html). The PDF document can also be Broadcasted through BEx Broadcaster 22

Better web printing – leveraging PDF and web controls PDF based BEx Web printing now include a variety of functionality, such as: 1. Fit to page width 2. Repeat column headers 3. Fit to one page 4. Wallpaper 5. Page margins 6. Export Themes (e. g. black/white) 7. Format & Alignment 8. Additional Headers & Footers 9. Print graphics and tables 10. Batch Printing via Broadcaster 23

Why upgrade? - Real-time Data warehousing gets better NW BI 7. x has more features for updates that does not follow the typical asynchronomous (batch) updates. This include: 1. We can use XML to fill the PSA directly 2. Daemon-based update from delta queue (BW API) 3. Daemon-based update of the ODS and minimal logging Note: XML documents creates many tags that will slow down large data loads due to the size of each XML record (relatively large) However, it works great for smaller streams of data. 24

Why upgrade? - BEx web Analyzer integrates Excel The Excel integration in the BEx analyzer is far better. Source: SAP AG, 2008 Unlike the old days of dynamic HTML, you can now use the BEx analyzer more like a real application without refreshing the whole page every time you click on something (this is due to the Java component in BI 7. x) News: BEx browser went away in BI 7. x 25

Why upgrade? - Drag-and Drop in BEx web Analyzer You can drag a characteristics into a filter area and automatically filter on that value, and you can also drag it into a column header or a row. BEx web analyzer is a better user tool than in the past. You now get the best world of Java & the web instead of the more ‘clunky’ user experience related to Dynamic HTML Building conditions and activating them was often confusing in earlier versions and exception based reporting was sometimes not easy to create for beginning users. BI 7. x has now simplified this with 26

More Administrative tools for management & development • • Enhanced Dataflow control (split delta) Administrator Cockpit (Web-based) BI Accelerator (high performance BIA) Enhanced Info. Sets with Info. Cubes Re-modeling and repartitioning of Info. Cubes New Data Transfer Process (DTP) Write-optimized Data.

BW Content Upgrades The new upgrade strategy from SAP is to provide BW technical releases as part of Net. Weaver and BI content add-ons, You do not need to perform a technical upgrade to update the business content. We now have SAP BI 7. 0 and the content releases 7. 0. 1 and 7. 0. 2 and 7. 0. 3 are now available. Planned upgrades should also include the content release 7. 0. 3. Details around each content release is available at http: //help. sap. com The current content (7. 0. 3) is available at: http: //help. sap. com/saphelp_nw 04 s/ helpdata/en/ 44/16 e 6 f 7 a 6 f 30 d 19 e 10000000 a 114 a 6 b/RN_703_en_final. pdf Apply content when you need it, to the technical release you have!! 31

How can you weigh the choices of Technical or Functional? Technical Function al Less Time Longer Project Less Money Tons of New Functionality Less Risk Increased User Satisfaction Less Functionality Opportunity to Sunset other BI solutions Technical upgrades have a set of activates that can be separated from a functional upgrade Source: SAP AG How much disruption and training can your organization absorb? 32 32

Weighing Towards a Technical Upgrade • A technical upgrade is the “safest” way to proceed • It is also the fastest and the least expensive • Your user community will notice little to no change UNTIL you start rolling out the new functionality Technical Functional Best Practice Minimal Risk to n Current Solutio rtal (if No Need for Po it) g not already usin dge Minimal Knowle Transfer 12+ Months $$$ nced Limited Experie Resources Source: SAP AG 33

Weighing Towards a Functional Upgrade • A functional upgrade (which includes all the technical activities) will make the biggest impression on your user community This will take longer – and cost more money • You will be able to sunset other solutions sooner • You will get the most Technical Functional Strong User Satisfaction Great New Functionality Small $$ Investm ent Less Risk More Scalable, Manageable Sy stem Opportunity to Sunset other BI t ools Source: SAP AG 34

Some hints on the upgrade – client, engines and usage types We are in a transition period, when some items of BI 7. x are separate engines, some are clients, and other are usage types. Key question: is you organization committed to java and the new BI 7. x direction? -- if so, go java ‘all the way’. . PS! SAP recommends having Java AS on dedicated servers Note: standard system copy and SAP migration tools have no standard support for splitting or merging systems with different usage types Source: SAP Installable software units May 2007 35

Some upgrade choices – the architecture 1 2 3 Note: Depending on your current installation of SAP BW, you have different upgrade options 36

Weaver Portal (if deploying) Functional Upgrade Development Team Delta Training (DBW 70 E) Report / Presentation Team Delta Training (DBW 70 R) Integrated Planning Training (DBW 70 P) User Training for new tools SAP official delta training at the client site (DBW 70 R, DBW 70 E) seems to be valuable for many clients. 38 38

Net. Weaver BI 7. x Upgrade paths Still supported… 39

Some hints – Upgrade programs SAPup and SAPjup You will need to install the Net. Weaver Application Server Java and the specific user type, before you can use all the features of BI 7. x (i. e. Business planning and analysis services, Enterprise data warehousing, Reporting and analysis scenarios etc). You can install this as a separate system or as an add-in to the upgraded ABAP server. SAP provides a software program called SAPup to help you upgrade the WAS (ABAP) and SAP BW. It is called a “system switch upgrade”. Note: if you already have java installed, you can also use the upgrade program called SAPjup, to upgrade the WASIf java. the WAS-Java was installed on the same system as the WASABAP (as an add-in) you need to run both the SAPup and SAPjup programs in parallel (see the Master upgrade guide for more details). 40

Some hints on the upgrade - Unicode conversion Unicode has been available since BW version 3. 5. 1. and is now highly recommended as part of the upgrade (hint web application designer is now also Unicode compliant). ﻳﻶﻺﻘﻔﻐﻎ תשרחפא д. Ф ǿ Ệẁ яь ф ǻǼ ǽ њ щ Some things to remember and plan for: 41

Planning Your Upgrade – a Hardware Example Production 12 CPU 96 GB RAM Sandbox 4 CPUs 32 GB RAM Development Test 4 CPUs 32 GB RAM This west coast company reallocated their Sun-6900 box (on Oracle) and have 3 Appservers on the production box. . More memory allows them to take better advantage of the parallel load of the BW system as well as to cache many of the frequently run queries (BEx Broadcaster) The hardware also allows them to have a system where performance between the boxes are comparable. Key numbers: 3. 1 Terabytes of data; 2810 named users and about 620 active users 42

Resources Team Lead Basis resource Technical reviewer BW Developer Upgrade Support External Regression Testers • A Dedicated team with a technical team lead (100%), a Basis resource (100%) and a technical reviewer (100% is required). • In addition, a dedicated “go-to” resource for technical issues is recommended. This should be an individual that have solid knowledge about the upgrade and have done his before. SAP resources should be considered, due to their contact network within the SAP organization. • Regression testing is required on behalf or the user community. This should be coordinated with the Power 43

Sample Timeline - complete landscape for large BW implementation The duration is driven by: 1. The number of BW systems in your landscape. 2. The new functionality your are rolling out 3. The support technology needed The more content you have the longer the upgrade (the more you have to regression test) 44

Minimum Timeline and Basic events: Do initial upgrade guide and note research [1 -2 days] Upgrade BW sandbox and do cursory issues check [1 -4 days] Upgrade a copy of BW production – have key development leads regression test all live content (both systems must be connected to other landscape environments – testing extractors too!) [2 -5 days (size/copy/hw depending)] Once the initial regression test is complete, create correctional transports. [3 -5 days] Post-fix, have full team in for “Upgrade buy-in testing” that all works properly [2 -3 workdays] KEY: now freeze development and release transports, upgrade development and a test system, incorporating the fix transports generated from the upgrade regression test. This should be a clean 2 You need to have the SAP solution Manager to generate the 4 day process. key during the upgrade to NW 2004 SR 1, and you will need to be on Solution Manager release 3. 2 SP 8 or higher to make it work (note: 805390). 45

Move into Landscape • At this point you have a temporary BW Dev to test patch, and perhaps static training, production and production support systems. • Ideally, you’d migrate the upgrade to these as soon as possible, but this is a stable point. You will have to decide, based on content, whether copying a test box to training makes sense (can preserve user master) • For production and production support, you’ve already done a dry run – just do production and copy back to production support unless the size makes this impractical [~ >500 GB] Hardware requirements changed if you also did Unicode conversion (recommended) 46

Step -1: Hardware install and BWS Copy BWX BWD BWQ In this real example, we are also installing new Hardware. This gives us lot of flexibility… BWP 3 1 BWS 2 BWX 4 BWX First, we copy the old development system to the new Sandbox (new HW) BWX January 21 Feb 28 4 11 March 18 25 3 10 April 17 24 31 7 14 Hardware install Copy BWD to new BWS Upgrade DB 2 to latest version Post processing of box Rename/restore old BWS box Download latest patches for upgrade 48 48

Step -1: BWS Unicode conversion, Java upgrade & test BWX BWD BWQ At this stage you should document and test all work that occurs. Some time has to be set aside for notes research and unforeseen issues. BWP 3 1 BWS 2 BWX 4 BWX We want to creating a repeatable process, so no ad-hoc activities are allowed.

Step -2: System copies BWX BWX You now freeze the development and can take copies of the BWD and BWQ system and prepare for upgrades. BWP 3 1 BWS 2 BWD 4 BWQ The old BWP is still running as the productive system. . BWX January Feb 21 Copy BWD Development freeze Rename BWD Copy BWQ Rename BWQ Copy PDW (no rename yet). It is still the production system. . 28 4 11 March 18 25 3 10 April 17 24 31 7 14 50 50

Step -3: BWD upgrade BWX BWX We now repeat the process. Remember, you have already upgraded BWD once (in step-1) and should know the need for any post processing. BWP 3 1 BWS 2 BWD 4 BWQ Don't ignore the need for technical and functional testing.

Lessons learned 54

Some areas you should focus on 1. Web Templates A semi-automatic conversion is possible using the BI 7. 0 Web Application Designer. (SAP Notes 832713, 832712, 1074997 & 1026591) Since Web templates are neither overwritten nor changed during migration, you can migrate templates as often as you want. Be prepared for manual intervention and fixes. 2. Info. Sets can become inactive after the upgrade Use program RSQ_ISET_MASS_OPERATIONS to activate all Info. Sets after the technical upgrade prior to running any queries 55

Some areas you should focus on 4. Query Conversion and Activation Recommendation: Once you decide to move to the new BEx tools, perform a one-time conversion of all queries in the system to BI 7. 0 to avoid having two query designer tools in use at the same time Use Win. Runner or a similar tool to open all queries in the BI 7. 0 query designer and save them. This will converts query to BI 7. 0. Run program RSR_GEN_DIRECT_ALL_QUERIES to regenerate all queries in the system 56

7 Key Points to Take Home • Is it cheaper to upgrade to new content or risk reinventing the wheel? • A BW architecture is part of a larger decision support landscape • An upgrade strategy should contain all Net. Weaver components • You upgrade strategy must include both release and content upgrades • Your upgrade time is largely a function of scope, your regression test strategy and the amount of content in your BW • The BI 7. x upgrade is an extensive one and you should 58
