Conversion of SAP System to Unicode

What is Unicode?

Unicode is the encoding standard which provides the basis for processing, storage and interchange of text data in any language in all modern software and information technology protocols.
Who Needs Unicode?
Acting in global business requires support of a Global Character Set!
(i)Companies running global business processes like Global HR Systems or Global Master Data Management
(ii) Companies offering Web Services to their customers: Global Master Data containing multiple local language characters.

(iii) Companies using Open Standards: J2EE and .NET integration(JAVA speaks Unicode)
(iv) Collaborative Business: Integration of Third Party Products that run on different code pages

Basic Concept
All Unicode Conversion Paths are based one concept
1. Prepare non-Unicode system.
2. Export non-Unicode database and convert non-Unicode data.
3. Create new Unicode database and import the non-Unicode database.
4. Do post-conversion activities in the Unicode system.

Prepare Non-Unicode System: Transaction SPUMG
In transaction SPUMG you collect and analyze character data without code page information. SPUMG creates control information that will be used during the database conversion.

SPUMG consists of several database scans

􀀟 Consistency Check
􀀟 Tables without Language Information
􀀟 Tables with Ambiguous Language Information
􀀟 Tables with Language Information
􀀟 Reprocess
􀀟 INDX Analysis
