Definition
A complex structure for integrating the characters of a character set into a special system and for communicating with other systems.
Each computer system contains different code pages. The SAP System contains code pages to map the Unicode format used in the SAP System or the ISO standard code pages (SAP(ISO) code pages) used in the SAP System, as well as other code pages for communicating with operating systems and peripherals (SAP(front-end) code pages).
Structure
Binary or hexadecimal codes are assigned to characters in the code pages. As the number of characters in the code page is limited, only a certain number of languages can be displayed using a code page.
Each code page is identified in the SAP System using a four-digit number. The SAP(ISO) code page 1100 that is based on ISO code page 8859-1 contains the characters for most Western European languages (see
Languages, Code Pages, and Conversions).SAP(ISO) Code Page 1100
For example, in the code page shown, the hexadecimal code E4 is assigned to the character "ä".
In the SAP System, the code pages are defined in the tables TCP02, TCP03, and TCP07.
All code pages that are based on ASCII character sets contain characters from the
Integration
As well as the hexadecimal code, an SAP-internal character number is also assigned to each character on a code page contained in the SAP System. This number is used when converting one code page format to another (see
Conversions in Accordance with the SAP Standard).
