  1. ECC6 Upgrade Project Lessons Learned Arieh Stark – Keter Plastic Ltd

  2. ECC6 Upgrade Project Aim: • Technical Upgrade to MySAP ERP 2005 ( ECC6 ) Why: • To prepare the foundation for NetWeaver / SOA Implementation • To enable new SAP Functionality . • To keep up-to-date – Mainstream Maintenance over.

  3. ECC6 Upgrade Sub Projects along the Way: • BIDI Migration • GUI Deployment / Citrix Deployment . • Keter’s AS400 Data Warehouse Replication from SAP. • 64 Bit Windows / SQL implementation. • Unicode enabling of our SAP Systems.

  4. ECC6 Upgrade Business Background: • The Keter Group has 22 SBU's dispersed globally in Israel, Europe, and the USA, connected to our central SAP System in Israel, working 24 hours a day, 7 Days a week.

  5. ECC6 Upgrade Technical: Before: • Operating System is Windows 2003 Enterprise. • Our 46C DataBase was SQL 2000 – Advanced- 900 GB. After: • Operating System is Windows 2003 Enterprise 32 Bit. • With x64 – we will only require Windows 2003 Standard. • Our new ECC6 Database is SQL 2005 – Enterprise 32 Bit and already 980 GB. • The Upgrade to ECC6 added 45 GB to the Database.

  6. Upgrade Project: Management: • Defines the scope of the Project – Planning. • Kick Off - Project beginning and end. • Support, Redefinition if required. Keeping to Deadlines. Technical Aspects: • Infrastructure sizing – Servers, Communication, Desk Top. Functionality: • Modifications and Custom Development. • Mapping of Delta Functionality. • Testing of functionality and Modifications . • Training

  7. ECC6 Upgrade Application / Functionality Testing: Elad Zafrir Eyal Halfon Perli Kaplan Marina Blumenkahl Karin Givon Ness/ Team Consultants( 4 ) Independent Consultants ( 3 ) Software Development / Modification: Ala Koifman Esther Bacshian Yair Israeli Ness/ Team Consultants( 4 ) Project Team: Keter Project Leaders: Shuky Sigura Arieh Stark HP Basis Team: Moshe Yerushalmi Yagil Hadri Boaz Paz NESS Advisory: Zohar Sarig Keter IT: Ilan Yacoby Igal Verbel

  8. ECC6 Upgrade Special Issues/Decisions: • BIDI Conversion with new SAP GUI Deployment – Before or at the same time as the Upgrade. • To Build a new Dev System from the Production System or upgrade both systems independently. • Down Time or Resource minimized Scenarios. • "In House" or "Fixed Price" Bid for the Project . • To Unicode enable all customer programs or leave it as a post-upgrade project. • SPAU – Clean the SPAU in the original 4.6C system or only in the Final System.

  9. ECC6 Upgrade Pre-Upgrade Analysis: Hardware Sizing: • From the Hardware Vendor – in our case HP. SAP Functional Upgrade Check: • SAP Service that checks Hardware and performance capabilities before and after Upgrade. Application Specific Upgrade ( ASU ) tools from SAP: • Includes application specific documents that outline problems with corresponding solutions including relevant SAP Notes. • For each application area – CO , PP , MM, FI and SD. • Tools to correct known problems – Variants etc – These tools were mostly built in to the ECC6 Upgrade Package already. Solution Manager: • Upgrade Roadmap Solution Browser: Release Notes: • Was not available at the time

  10. ECC6 Upgrade Pre-Upgrade Analysis: Internal Interface analysis: • ECC6 To/From external Systems – "Real Time" machine monitoring system , Time Clocks , VAT etc. • Interfaces between BW , APO and ECC6. IntelliCorp Assessor Upgrade Edition: • Both for Functionality and Project Scope • Required a live ECC6 System to compare to. • We used an Upgraded to ECC6 Dev system and the 4.6C Production System as reference.

  11. ECC6 Upgrade Intellicorp Assessor Upgrade Edition: Executive Summary: • Project Scope. Excel Lists containing: • All SAP programs according to SAP User and their index of modification in ECC6 according to Application Area. • New SAP transactions in ECC6. • Replaced Transactions in ECC6. • Used/Unused Customer programs with Usage statistics . • Customer Batch Input Programs and used BAPI's with code placement that would probably need to be changed in ECC6.

  12. ECC6 Upgrade AUE Highlights: • The Application Area was not always clear – We manually changed the Area where there were problems – a day's work. • This is a SAP Issue because it is not always accurate. • We sorted the Lists according to Application Areas and the lists were given to the relevant "Top Users" • There was no indication of the last Programmer who did a change in the Program list. • Consequently – we merged the Programmer Name into the Excels. • This allowed us to sort the Program Changes and give the Program Change List to relevant Programmers. • We also had a list of Customer programs that were not in use ,but they were called by other programs • Estimation of required resources - manpower. • The Excel sheets were passed onto the Keter Top Users and Programmers as a preparation and guide for functional and application Testing.

  13. ECC6 Upgrade Our Upgrade Plan : Upgrade a copy of the Development System as a trial run. • To see if we were missing anything – Software CD's , Notes etc. • CookBook entries. Upgrade a copy of the Production System as a Upgrade Sandbox System: • Used to test functionality – correct bugs . • Created a separate transport for each program. • We saved the transports and ported them to the next stage. Final Upgrade of the Development Systemand Interim Test System. • Simultaneous upgrade of a copy of the Production System as an Interim Test System • Code Freeze on the R3 Landscape. • Porting of Transports from the Sandbox System to both the Final Dev System and the Interim Test System. • SBU testing and training was done on the Interim Test System. Rehearsal Upgrade of the Production System. • Testing and Final System Verification and acceptance was done on this System. Final Upgrade of the Production System.

  14. ECC6 Upgrade Testing and Training Scenarios: Application and Functionality: • Performed by Top Users and Implementation Consultants in the Keter Headquarters. • Used the Lists derived from the Intellicorp Upgrade Assessment. • Was done on our Upgrade Sandbox System first. • Corrections / modifications were done on this system – the Transports were ported to the Final Dev system. • Then testing was done on the Interim Test System. • 2nd Level testing was done by the Top Users in the SBU's. • They concentrating on their most complex procedures. • They were also responsible for local training. • This testing and training was done on the Interim Test System.

  15. ECC6 Upgrade Testing and Training Scenarios: Modifications and Customer Development: • Checked and tested by the relevant Programmers / Top Users. • Used the Intellicorp Upgrade Assessment derived Lists.

  16. ECC6 Upgrade Project Gantt:

  17. ECC6 Upgrade Upgrade Trial Run: Copy of Development System DEV Test/QA PRD R3 • To check if anything is missing. • Notes, Downloads, etc. • Ran Intellicorp Upgrade Assessment ECC6 DEV Trial

  18. ECC6 Upgrade Upgrade PRD to Sandbox: Copy of Production System DEV Test/QA PRD R3 • Testing • SPAU • Corrections • Save Transports ECC6 SandBox

  19. ECC6 Upgrade Upgrade Final DEV and PRD (Test): Copy of Development and Production System DEV Test/QA PRD R3 R3 Code Freeze. SPAU again. Transports from Sandbox Testing and Training in SBU’s ECC6 DEV Final Test/QA Transports

  20. ECC6 Upgrade PRD Rehearsal: Copy of Production System DEV Test/QA PRD R3 Testing and Final System Verification and Acceptance ECC6 DEV Final PRD Rehearsal Transports

  21. ECC6 Upgrade Final PRD – Go Live: Copy of Production System DEV Test/QA PRD R3 • Contingency Plan for Roll Back • Original PRD system exists • IP and Server Name change only. ECC6 DEV Final PRD Final Transports

  22. ECC6 Upgrade Test/QA from PRD: DB Copy of Production System DEV Test/QA PRD R3 ECC6 DEV Final Test/QA PRD Final DB Copy

  23. ECC6 Upgrade Glitches during the Upgrade Project: • Localization CD at the last moment from NESS. • HR SPAU entries.

  24. ECC6 Upgrade Post Upgrade: Go-Live Problems/Issues and Lessons: • Application Problems • Citrix/GUI Deployment Problems • Basis Problems.

  25. ECC6 Upgrade Application Problems: 1st Week Problems: • EDI did not fully work – very serious . • SAPEVT did not work. • HR Master data program did not work as before. • COHV changed - no CO13. • Changes to CS01/2/3. • Replacement of MRHR with MIRO - Traumatic 2nd Week Problems: 3rd Week Problems:

  26. ECC6 Upgrade GUI and Citrix Deployment: Hebrew GUI Problems: • 6.40 GUI icons are different from 46D • Field Painting in Hebrew. Citrix Problems: • Local DeskTop and Network Mapping. • Printing through LOCL. • Requires better quality communication lines.

  27. ECC6 Upgrade Basis : • SAP Functional Upgrade Verification. • Performance tuning. • Database tuning. • Memory Tuning. • SQL 2005 Service Pack 2 – waiting …. • SAP ABAP and Basis Support Packs. • Waiting for COP 11.

  28. ECC6 Upgrade Summary: • The SAP Technical Upgrade Process worked like a "Charm" • Requires a thorough preparation and analyses of Application functionality. • Mapping - Assessment for Upgrade Tool ( Intellicorp ) . • Requires Thorough Testing and User Training.

  29. ECC6 Upgrade Lessons Learned: • Keep the project simple - do not implement any new functionality. • Do not try to mix too many projects together. • It was problematic to Deploy Citrix and the new SAP GUI at the same time. • The Upgrade project must be known to Localization at Ness . • Localization CD at the last moment. • Do not strive for too much Perfection – Know the Business Risks and Limits. • Constantly Update Management and all Project People. • Have a Contingency Plan for Roll Back.
