hi,

what is the major difference using

call method cl_gui_frontend_services->gui_upload.

instead of

call function gui_upload

Hello and welcome,

at least in Rel. 4.6C nothing - as you can see from source code:

method GUI_UPLOAD.

• ...

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

FILENAME = FILENAME

FILETYPE = FILETYPE

HAS_FIELD_SEPARATOR = HAS_FIELD_SEPARATOR

HEADER_LENGTH = HEADER_LENGTH

IMPORTING

FILELENGTH = FILELENGTH

HEADER = HEADER

TABLES

DATA_TAB = DATA_TAB

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.

CASE SY-SUBRC.

....

Maybe in higher releases there's a difference.

ECC5 no difference

The difference is one is object oriented and other one is not. Other than that there is no difference. Whatever advantages you have with going towards an object oriented coding, will be available with the method.

internally the class also uses GUI_UPLOAD ..........

but its better to use the class method because of compatibility issues to later versions

Hi Venkatesh,

SAP is now moving towards Netweaver.

So after some versions these function modules will become Obsolete.

As GUI_UPLOAD replaced UPLOAD in 4.7 version, CL_GUI_UPLOAD_SERVICES->GUI_UPLOAD replaces GUI_UPLOAD in future versions.

Thanks,

Sreekanth

Welcome to SDN.

if you look at the code inside

cl_gui_frontend_services->gui_upload they use gui_upload function.

there is no difference.
