We have faced this common issue that the trailing spaces are getting removed when we download the file using GUI_DWNLOAD FM. Well, this problem can be easily resolved by the following code.
TRUNC_TRAILING_BLANKS_EOL = ' 'Use this while calling the GUI_download FM.
CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
FILENAME = 'C:/Vendors1.txt' "file path
FILETYPE = 'DAT'
TRUNC_TRAILING_BLANKS_EOL = ' '
* IMPORTING
* FILELENGTH =
TABLES
DATA_TAB = VENDOR_TAB
* FIELDNAMES =
* EXCEPTIONS
* FILE_WRITE_ERROR = 1
* NO_BATCH = 2
* GUI_REFUSE_FILETRANSFER = 3
* INVALID_TYPE = 4
* NO_AUTHORITY = 5
* UNKNOWN_ERROR = 6
* HEADER_NOT_ALLOWED = 7
* SEPARATOR_NOT_ALLOWED = 8
* FILESIZE_NOT_ALLOWED = 9
* HEADER_TOO_LONG = 10
* DP_ERROR_CREATE = 11
* DP_ERROR_SEND = 12
* DP_ERROR_WRITE = 13
* UNKNOWN_DP_ERROR = 14
* ACCESS_DENIED = 15
* DP_OUT_OF_MEMORY = 16
* DISK_FULL = 17
* DP_TIMEOUT = 18
* FILE_NOT_FOUND = 19
* DATAPROVIDER_EXCEPTION = 20
* CONTROL_FLUSH_ERROR = 21
* OTHERS = 22
.
IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.The above code will leave the space at the end of every line and your issue will be resolved.
