Technical upgrades • Upgrades with NetWeaver • Planning and Executing the upgrade • The upgrade plan • The business case • Staffing, duration and scope • Examples • Wrap up • Bonus material: ideas for the business case

  3. 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 - customer-specific maintenance Why Upgrade – end of support… #1 reason for upgrade: “Because I had to!”

  4. 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. Five years of mainstream maintenance at the standard maintenance fee One year of extended maintenance at an additional two percent maintenance fee* Two more years of extended maintenance at an additional four percent maintenance fee per year*. After these eight years, customer-specific maintenance begins, providing a program of support and services uniquely tailored to individual customer requirements. The plan covers SAP solutions based on the SAP NetWeaver platform including mySAP SCM, SRM, PLM, CRM, and industry add-ons. *check with your account executive to see what your fee may be

  5. The Bigger Picture – NetWeaver ?? NetWeaver is a set of solution components that provides a comprehensive architecture. All components of NetWeaver 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

  6. 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 Accellerator • BEx Broadcaster • BEx Query Designer • BEx Report Designer • ReModeling 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

  7. 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 support for HTML tags. 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 Designer.

  8. Why upgrade? - BI Accellerator 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 each data load HP, Sun and IBM have standard solutions ranging from $32K to $250K+ that can be installed and tested in as little as 2-4 weeks (+ SAP license fees)

  9. New Broadcaster features of BI 7.x New Object TypesYou 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 FormatsNew output formats are based on the distribution type you select. But, you now can broadcast web documents as PDF files.

  10. 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.

  11. 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. You can use multiple distribution types to create a setting that broadcasts over many channels (e.g., the printer and the portal). 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.

  12. 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 NetWeaver 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

  13. Better web printing – leveraging PDF and web controls PDF based BEx Web printing now include a variety of functionality, such as: • Fit to page width • Repeat column headers • Fit to one page • Wallpaper • Page margins • Export Themes (e.g. black & white) • Format & Allignment • Additional Headers & Footers • Print graphics and tables • Batch Printing via Broadcaster

  14. BEx Query Designer gets a ‘facelift’ The 3.5x BEx Query Designer This new property pane makes it easier to format and control displays than in the past. You can choose if you want the old or the new look after the upgrade The BI 7.x BEx Query Designer Note:

  15. 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, header-footer 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 3rd party tools to address structured reports.

  16. 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 infocube as well. In the first releases of BI 7, 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 (dictionary-based) 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.

  17. 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. 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 Source: SAP AG ASUG Security Upgrade by Eric Dwyer, Nike: http://www.asug.com/client_files/Calendar/Upload/EA1_upgrade_bw_security_2.ppt

  18. Why upgrade? - More Authorization Objects Authorization objects for the Data Warehousing Workbench: S_RS_DS: For the DataSource or its sub objects (BI 7.x) S_RS_ISNEW: For new InfoSources 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 Authorization objects for the Business Explorer: S_RS_DAS: For Data Access Services 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 InfoAreas and application components; CNG_RUN - Attribute change run You get the ability to use much lower security granularity for developers and users!! Source: SAP AG July 2008

  19. Upgrading to BI 7.x Security SAP has created an ABAP migration tool to help you upgrade security in NW BI 7.x. To access it, goto transaction code SA38, and execute migration program RSEC_MIGRATION. About 80% of you security setup is expected to make it using this tool. i.e. customer exit variables for the object 0TCTAUTHH does not migrate, and you will have to manually reassign all hierarchy nodes. While you upgrade, the old security is left intact and you can switch back if absolutely needed (IMG setting). Plan to test…test..and test… More Great Details about the Security Upgrade at : http://csc-studentweb.lrc.edu/ swp/Berg/Articles/ BI 7.x_Authorizations.pdf (Source: Amelia Lo, SAP)

  20. Why Upgrade? - Better interface for ETL Design On a typical DW project, 40-60% of project effort will be spent on data integration, transformation and loads (used to be higher when tools were more immature). SAP NetWeaver BI 7.x has a new and better GUI and formula editors to write complex transfer rules, update rules and data mapping.

  21. Why upgrade? - BPS Integrated Planning (still supported) 1 2 3 4 5 6 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 InfoProvider InfoProvider Aggregation Level Planning Sequence Pattern Filter Planning Function Source: SAP AG, 2008

  22. 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 only Gotchas.. Your users now need to install Acrobat Reader (free at http://www.adobe.com/ products/acrobat/readstep2.html). The PDF document can also be Broadcasted through BEx Broadcaster 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 validated.

  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 dataloads 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. 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) Source: SAP AG, 2008 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 a row. 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 more wizards that helps users to build this step-by-step. 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

Technical upgrades • Upgrades with NetWeaver • Planning and Executing the upgrade • The upgrade plan • The business case • Staffing, duration and scope • Examples • Wrap up • Bonus material: ideas for the business case

  27. BW Content Upgrades The new upgrade strategy from SAP is to provide BW technical releases as part of NetWeaver 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_nw04s/ helpdata/en/ 44/16e6f7a6f30d19e10000000a114a6b/RN_703_en_final.pdf Apply content when you need it, to the technical release you have!!

  28. How can you weigh the choices of Technical or Functional? Source: SAP AG 28

  29. 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 Source: SAP AG

  30. 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 benefits – from usability and management Source: SAP AG

  31. An Upgrade Strategy Think bigger than BW.. Apply content as soon as feasible. Especially if you have on-going development work. This way you can avoid many “work-arounds”. You should seriously consider having all NetWeaver components on the same upgrade strategy instead of selecting each component for upgrade. This will help in the shared extractors and also substantially simplify the upgrade planning and landscape. Look at SAP’s release strategy for each component you are using and plan ahead,instead of last-minute “must-do” projects.

  32. 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’.. 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

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

Technical upgrades • Upgrades with NetWeaver • Planning and Executing the upgrade • The upgrade plan • The business case • Staffing, duration and scope • Examples • Wrap up • Bonus material: ideas for the business case

  35. Typical Training Requirements 35

  36. Upgrade Pre-planning It is important to communicate the goals and timings to the technical team to help them prioritize their research and activity or hardware setup Communicate goal of having existing content continue to work to functional test team, so they do not get hung up in testing new features before the upgrade is in production. You need to have the SAP solution Manager to generate the key during the upgrade to NW2004 SR1, and you will need to be on Solution Manager release 3.2 SP8 or higher to make it work (note: 805390).

  37. NetWeaver BI 7.x Upgrade paths Still supported…

  38. Some hints – Upgrade programs SAPup and SAPjup You will need to install the NetWeaver 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 WAS-java. If the WAS-Java was installed on the same system as the WAS-ABAP (as an add-in) you need to run both the SAPup and SAPjup programs in parallel (see the Master upgrade guide for more details).

  39. 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). Some things to remember and plan for: яьфдФњщ Ệẁ ǻǼǽǿ תשרחפא ﻲﻶﻺﻕﻒﻏﻎ

  40. Planning Your Upgrade – a Hardware Example Example 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. Production 12 CPU 96GB RAM Sandbox 4 CPUs 32GB RAM Test 4 CPUs 32GB RAM Development 4 CPUs 32GB RAM Key numbers: 3.1 Terabytes of data; 2810 named users and about 620 active users

  41. Team Lead Team Lead Basis Basis Technical reviewer Technical reviewer Upgrade Support Upgrade Support Regression Testers Regression Testers resource BW Developer External External Resources • 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 Users or existing developers.

  42. 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)

  43. 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 any 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 2-4 day process. Plan for regression test glitches – and production cut-over.

  44. 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 [~ >500GB] Hardware requirements changed if you also did unicode conversion (recommended)

  45. What We’ll Cover … • Why upgrade • End of support • New support strategy & NetWeaver • New features and capabilities • Creating an upgrade strategy for the future • Content Vs. Technical upgrades • Upgrades with NetWeaver • Planning and Executing the upgrade • The upgrade plan • The business case • Staffing, duration and scope • Examples • Wrap up • Bonus material: ideas for the business case

  46. Step -1: Hardware install and BWS Copy In this real example, we are also installing new Hardware. This gives us lot of flexibility… First, we copy the old development system to the new Sandbox (new HW) BWX BWD BWQ BWP 3 1 2 4 BWS BWX BWX BWX 46

  47. Step -1: BWS Unicode conversion, Java upgrade & test 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. We want to creating a repeatable process, so no ad-hoc activities are allowed. BWX BWD BWQ BWP 3 1 2 4 BWS BWX BWX BWX

  48. Step -2: System copies BWX BWX BWX BWP You now freeze the development and can take copies of the BWD and BWQ system and prepare for upgrades. The old BWP is still running as the productive system.. 3 1 2 4 BWS BWD BWQ BWX 48

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

  50. Step -4: The real test -- BWQ upgrade BWX BWX BWX BWP Notice, we refreshed the new BWQ from BWP, so this is really a BWP upgrade… 3 1 2 4 BWS BWD BWQ BWX
