1.为文件PARAMETERS定义F4帮助 FUNCTION NAME:
TB_LIMIT_WS_FILENAME_GET
CALL FUNCTION 'TB_LIMIT_WS_FILENAME_GET'
EXPORTING
DEF_FILENAME = "默认文件类型
DEF_PATH = "默认文件路径
MASK = "文件类型
MODE = "方式
TITLE =
IMPORTING
FILENAME = IN_FILE "获得IN_FILE名
PATH =
FILE =
EXCEPTIONS
SELECTION_CANCEL = 1
SELECTION_ERROR = 2
OTHERS = 3
.
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
2.上传FILE数据到内表
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
FILENAME = IN_FILE "文件名
FILETYPE = 'DAT' "数据格式
HAS_FIELD_SEPARATOR =
HEADER_LENGTH = 0
READ_BY_LINE = 'X'
DAT_MODE = ' '
CODEPAGE = ' '
IGNORE_CERR = ABAP_TRUE
REPLACEMENT = '#'
CHECK_BOM = ' '
VIRUS_SCAN_PROFILE =
NO_AUTH_CHECK = ' '
IMPORTING
FILELENGTH =
HEADER =
TABLES
DATA_TAB = GT_TABLE "数据导入的内表
EXCEPTIONS
FILE_OPEN_ERROR = 1
FILE_READ_ERROR = 2
NO_BATCH = 3
GUI_REFUSE_FILETRANSFER = 4
INVALID_TYPE = 5
NO_AUTHORITY = 6
UNKNOWN_ERROR = 7
BAD_DATA_FORMAT = 8
HEADER_NOT_ALLOWED = 9
SEPARATOR_NOT_ALLOWED = 10
HEADER_TOO_LONG = 11
UNKNOWN_DP_ERROR = 12
ACCESS_DENIED = 13
DP_OUT_OF_MEMORY = 14
DISK_FULL = 15
DP_TIMEOUT = 16
OTHERS = 17
.
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
