字符集转换_SAP
1 系统内部转换命令(一般建议不直接使用)
SYSTEM-CALL CONVERT ID id DATA data
ENCODING encoding
ENDIAN endian
swift 字符串转数组IGNORE_CERR ignore_cerr N n
POSITION position
REPLACEMENT replacement
LEN len
BUFFER buffer
ERR err.
Text and lines are converted between different formats.
2 使用SAP系统封装的类CL_ABAP_CONV_IN_CE and CL_ABAP_CONV_OUT_CE
样例
data STR TYPE C.
DATA: S TYPE STRING,
LEN TYPE I.
DATA: CVTI_UTF8 TYPE REF TO CL_ABAP_CONV_IN_CE.
FIELD-SYMBOLS : TYPE X.
ASSIGN STR TO CASTING.
CVTI_UTF8 = CL_ABAP_CONV_IN_CE=>CREATE( ENCODING = 'UTF-8' INPUT = ).
CALL METHOD CVTI_UTF8->READ
IMPORTING
DATA = S
LEN = LEN
EXCEPTIONS OTHERS = 1.
STR = S.
3 使用sap封装的Form
要包含以下单元:RSCPICINC
封装的form
CONV_TO_ASCII
CONV_TO_EBCDIC
CONV_TO_UTF8
CONV_FROM_ASCII
CONV_FROM_ASCII
CONV_FROM_EBCDIC
4使用sap封装的函数(外部->系统默认代码,系统默认代码->外部)
function translate_codepage_in.
*" IMPORTING
*" VALUE(CODEPAGE_FROM) TYPE ABAP_ENCOD
*" TABLES
*" T_DATA
*" EXCEPTIONS
*" ERROR_TRANSLATE
function translate_codepage_out.
*" IMPORTING
*" VALUE(CODEPAGE_FROM) TYPE ABAP_ENCOD
*" TABLES
*" T_DATA
*" EXCEPTIONS
*" ERROR_TRANSLATE
5使用TRANSLATE命令
TRANSLATE c ...FROM CODE TO CODE PAGE g2.
6 常见代码编号
EBCDIC = '0100'
ASCII = '1100'
UTF8 = 'UTF-8'
7 相关的元素
ABAP_ENCOD
TCP00(表)
