  • 5. Overview Unicode Overview – Why, What & How Unicode & ECC 6.0 2.1. Project comparison 2.2. Paths to target 2.3. Complicating factors Case Study Resources Wrap-Up
  • 6. Moving from R/3 Non-Unicode (NUC) To be: up to ERP 6.0 Unicode (UC) SAP ERP 6.0 UC Outage Production Database windows? Testing? migration? 32->64 bit? HW migration? SAPGUI OS upgrade? MDMP or SCP? Rollout? HW upgrade? Database upgrade? SAP Solution Manager? ABAP work? As is: Sandbox hw? Training? Backout SAP R/3 NUC strategies? Production

  • 8. Why Convert – SAP Customer letter Apr 2006. – SAP Customer letter Apr 2006. ―It is a strategic target of SAP to move our customer base to Unicode. End of support for non Unicode based systems for future releases is being discussed internally.‖
  • 9. Why Convert – more reasons Inherently a non-Unicode system cannot ―understand‖ all the characters that could be sent from a Unicode system SAP Java systems are only Unicode Mixed landscapes may or may not work even in Single Code Page environment. Note 838402 - Problems within non-Unicode system landscapes Note 975768 - Deprecation of Java features with non-Unicode Backend
  • 10. Why Convert ―Non-Unicode code pages support only a small portion of the world- wide existing character sets. Any character conversion based on these code pages therefore bears the risk of silent data loss.‖ ―Existing non-Unicode systems are still supported, but due to the intrinsic limitations of non-Unicode code pages SAP recommends a conversion to Unicode, especially when upgrading system to Netweaver 7.0 (ERP 2005) and higher releases.‖
  • 11. Why Convert SAP Note 838402 – Problems with Non-Unicode SAP Landscapes Only languages that can be covered by one single non-Unicode code page can be supported within each non-Unicode system. Some characters that are used in your language are not supported by the installed non-Unicode code page. Integration with Unicode based technologies: Most technologies used within an SAP application context are Unicode based When using these technologies together with a non-Unicode SAP system uncontrolled data loss can occur.

  • 14. Terminology CU&UC — Combined Upgrade and Unicode Conversion Common abbreviation used in documentation UTF — Unicode Transformation Format Flavors differ in storage UTF-8, UTF-16, UTF-32 UC / NUC — Unicode / non-Unicode Used in SAP documents/websites/ ―exe directory names‖ NUC system types SCP — Single Code Page MDMP — Multi-Display Multi-Processing (i.e. multiple code pages) Blended CPs — Special Code Pages for certain language combinations
  • 15. The “What” is about Characters American Standard Code for Information Interchange (ASCII) . There are 95 printable ASCII characters, numbered 32 to 126
  • 16. What is a code page? Code Page (from SAP Glossary) Character set that defines the symbols that can be used in programs and displayed by output devices such as printers and terminals. 1 character = 1 byte
  • 17. What is Unicode? International standard Characters from virtually every language and script assigned a unique Unicode Scalar Value Unicode Scalar Value: a number written in hexadecimal notation. Notational convention "U+" is prefixed to the Scalar Value. UTF - Unicode Transformation Format Note: Unicode only specifies text storage not translation. It does not automatically make more languages available.
  • 18. Unicode Storing Characters Byte Order Reversed 8-bit Mostly 16 bit
  • 19. Required code pages depend upon languages used Multiple languages ≠ multiple code pages (e.g. code page 1100) Source: SAP Note 73606 attachment “R3languages.pdf”
  • 20. Do I have to Convert in Order to Upgrade to ECC 6.0? Yes No MDMP or SCP BCP
  • 21. Code Pages in Use? RSCPINST or SE16 TCPDB
  • 22. Blended code pages?
  • 23. Basic Unicode Conversion Uptime Processing SPUMG & UCCHECK Downtime Processing R3Load R3Load SAP Database (Export & (Install & SAP Database With Conversion) Import) With Non-Unicode Unicode Data

  • 25. Unicode Overview – Why, What and How Unicode & ECC 6.0 2.1. Project comparison 2.2. Paths to target 2.3. Complicating factors Case Study Resources Wrap-Up
  • 26. Unicode & ECC Project Comparison HW, OS, DB, SAN, Basis Unicode Conversion Dependent mostly technical upon number & ABAP effort of “Z” objects
  • 27. Paths to Unicode ECC 6.0 Separate projects If R3 4.7 or Unicode ECC 5.0 Upgrade Conversion If Single Unicode Upgrade Code Page Conversion Note: CU&UC Downtime is normal SAPup downtime plus DB export/import
  • 28. Project complicating factors Hardware factors Sandbox availability Storage (exports, extra systems) OS Upgrade / patches Migration (new hw and/or new architecture eg x86->x64) Can be Parallel development (existing and upgraded) significant Database factors efforts but do not Upgrade / patches change Conversion (if source not Unicode compatible) business Size process Export/Import time Backup/Restore time Other factors MDMP requires more Unicode preparation steps than SCP Number of ―Z‖ Objects – Unicode syntax corrections / Upgrade driven changes
  • 29. Path to Unicode ECC 6.0 Yes Separate Projects Get these May be done DB > ~500GB done as days/weeks & early as possible before SCP Gui Rollout Hw migration Min SP for Unicode CU&UC No DB upgrade Latest kernel & spam/saint vers.
