Summary : 
      This SAP Note addresses the requirements and setup for SAP R/3 to operate with Korean language in a Korean Windows environment. It specifies necessary frontends like Korean Windows 3.11, 95, and NT where SAPgui will automatically recognize and switch to Korean. Users must select Korean fonts from the multi-byte font menu and set SAP_CODEPAGE to 8500. Detailed configurations for application servers, database prerequisites with specific OS/DB combinations, and supported Korean languages (Language Key 3 for Korean) are provided. Additional resources and OSS notes are referenced for detailed setups such as installing and configuring the Korean environment in R/3 systems.
