- 4. Current Status • Where is everyone now? • 11.5.10 • Earlier versions • What modules? • Financials • Supply Chain • Manufacturing • How long have you been on Oracle? • >2 years • >5 years • >10 years • Who has been through an upgrade (i.e. 11i)? • Why upgrade? • Support • New functionality • Implementing additional modules
- 5. R12 Overview • Oracle’s Major Release after 11i • Various versions have been release semi-annually • R12.0 thru 12.0.6 and 12.1.0 to 12.1.3 • Bug fixes • The R12 versions have functional enhancements and changes • Major Enhancement • Centralize functions that were common amongst modules • User Interface changes • More Web-based look-and-feel • Common Data screens and functions moved to java framework • Suppliers • Customers • Technology Changes – JRE instead of JInitiator
- 6. R12 Projects Industry` Public, Regional Ohio Industrial Equipment Large Steel Utility ($3 Billion) Manufacturer ($500 Million) Manufacturer ($2 Billion) Location Dayton, OH Mason, OH West Chester, OH Versions 12.06 12.1.2 12.1.2 Timeline 9 months 6 months 9 months IT Staffing 2 Internal 5 Internal 2 Internal (FTEs) 8 External 4 External 3 External 2 Developers 1 Developer DBAs 2 Internal Outsourced / Hosted Outsourced Scope 12 Modules: Financials, Supply 18 Modules: Financials, MFG, 3 Modules; Financials Chain, HRMS Supply Chain, HRMS Custom ~300 custom objects, ~500 custom objects ~100 custom objects Objects 7 complex interfaces Minimal interfacing Moderate interfacing Down 70 hour upgrade window 69 hour upgrade window 48 hour upgrade window Time Issues 90 patches, 269 issues logged, 50 patches, 145 SR’s, 418 issues 45 patches, 120 SR’s, 214 issues 811 test scripts logged logged
- 7. The GOAL Don’t mess it up! • Availability • The system will be available on Monday morning. • Shortest possible downtime. • Business Continuity • On Monday morning everyone can do their job. • At the end of the period, the business can close the books. • Have system on Oracle R12
- 8. The Approach Repeat Test Production Plan Test Upgrade Upgrade Issues Cookbook Patch List Steps Multiple practice rounds determine correct steps and patches to ensure a successful upgrade. More rounds => Less Risk
- 9. Sample Plan
- 10. Lessons Learned Project Management • Agree on scope upfront • Maintain a “parking lot” for items to be considered after go live • Maintain an issues list • Maintain awareness of ongoing 11i Production support changes • Intermediate milestones • Weekly DBA meetings Project Schedule • Ensure that the project phases and milestones are aligned with important business considerations such as quarter end/year end • Set expectation that going-in schedule is subject to change • Build in a contingency month if possible • Initial phase was a “bug hunt” to try and find obvious glitches – try to navigate through and test basic functions • Subsequent upgraded environments serve as “Pilot” systems to help finalize R12 setups and resolve any bugs • Following “Pilots”, perform formal tests with business users
- 11. Lessons Learned Custom Objects • Many will need to change • Many of the changes will be minor • Some will be rewrites • All need to be tested thoroughly • Some will work with old data but not with new Testing • Ensure you have comprehensive test scripts to cover all processes • Involve the business team – creating test scripts and executing • Test with “old data” (that was upgraded) and new data • Be aware of how Subledger Accounting data is converted • Don’t assume anything – each upgrade iteration brings new 11i data • Establish a test lab with PC’s so that business team can participate in a focused environment • Test standard and custom report printing
- 12. Testing Flow Patch Process Used in Next Test Issue Round Change Cookbook Step
- 13. Cookbook Cookbook Steps • Well documented • Assigned • Timed
- 14. Lessons Learned Patching • Take the most recent CPC (critical patch collections) proactively at the start of the project • Evaluate timing of other CPCs and new releases as the project progresses • Track every patch applied in every environment - you won’t want to take all of them forward - Important to know what’s where if you have more than one instance • Set a “patch freeze” date prior to the cutover event • Be aware of patches for a single bug that might contain additional bug fixes. If “one off” patches are unavailable, you must re-test all affected files. • List of specific patches for specific issues can be provided Training • Depends on number of users, number of testers, use of modules • Some modules had no training – HR • Some had full classroom training – AP, Inv • Some fell in the middle – GL, AR • Some do remedial training
- 15. Lessons Learned If you have interfaces consider this carefully! Oracle will be (partially) down. Interface Plan • What systems will be affected by downtime? • Linked systems • Interface files to those systems. • ODBC links/users – turn them off – The DB will be up! • Process every file and every transaction • Once and • Only once • Will there be format changes or program changes? • Mitigate the impacts • Assign specific actions for each interface • Who will process files? • When will the files be processed? • Who needs to know about what affect to what systems?
- 16. Lessons Learned Cutover Event • Cutover planning starts early in the project • Communicate, Communicate, Communicate – • No surprises • Assume nothing • “Cutover Plan” - instructions should be detailed enough that others could do the steps in someone’s absence • Assign the steps – consider passwords and responsibilities (security) • Practice the steps with each technical upgrade • Time the steps, automate if possible using Dataloader, SQL, FNDLOAD • Develop communication plan, fallback plan, 24x7 contact list (including key third-party vendors), Go/no-go decision support • Allow time for business team to do some basic testing before the system is open for business on the first day after cutover • Manage the impact to interfaced systems (inbound and outbound) This is what we’ve trained for people!
- 17. Lessons Learned Experience • Companies considering an upgrade have experienced Oracle Application teams. • Find someone experienced with the upgrade. • The upgrades get quicker and less risky as more upgrade experienced people become available to help. • Experienced people should provide a head start. • Cookbook • Patch lists • Key risk areas – what to test first • Coding change examples • XML Template examples (checks and other payment documents) • Templates for other project deliverables • Project plan • Impact documents • Starting points for cutover plan
- 18. Results STATISTIC – AP and Payments modules comprised a large portion of the project issues and patches. 1 in every 6 issues Almost 1/3 of patches Project Issues Log Applications Patches AP, Payments Other Modules AP, Payments Other Modules 12.0.6 project - 35 Oracle Service Requests (SR’s) for AP/IBY modules The number was much less for the 12.1.2 project.
- 19. New in R12 Dr Cr 6 Major Initiatives General & Ledger Ledger Ledger Sets 1. Ledger and Ledger Sets Subledger Accounting (SLA) 2. Subledger Accounting Tax Inter Bank Engine Company Model 3. MOAC 4. Intercompany 5. Tax Engine Multi-Org Access 6. Bank Model Control Inventory Receivables Projects Work in Process Purchasing Payables 19
- 20. Major Changes Payables • 11i Payables split into 4 parts in R12 • Payables • Payments • Tax Who moved my • Accounting - SLA cheese? • Supplier form re-written • Bank data centralized • Lines added • Trial balance and write-offs different with some upgrade concerns Payments • All new module • Some development required • Numerous setups WebADI • Client ADI is gone • Other modules can be used to fill the gaps.
- 21. Major Changes Subledger Accounting • Create accounting process added to all financial modules • Affects GL Drill-back • Some date idiosyncrasies • Powerful capabilities available (but not required) • One accounting method change means full new method – decide early EBTax • Regime will upgrade but don’t use it! • Not supported • Not extendable • Difficult to use • Set up a new regime • Good time to go to a 3rd party provider • Lots of power – lots of learning Printing Architecture and BI Publisher • PASTA is available but not exact • Some reports need to be opened and printed from Adobe
