Hi,

It is a way of represeinting the same funciton in procedural language using CALL FUCNTION and in classes (OOPS based) .

CALL FUNCTION is a traditional approach, using the classes is a OO approach

Just call the class CL_GUI_FRONTEND_SERVICES in the Pattern button to call a class, in that ABAP Object Patterns specify the class name CL_GUI_FRONTEND_SERVICES, method name specify the GUI_UPLOAD.

this way we can call the Class. As this class is the STATIC class there is no need of creating a object for it. We can directly use this class in the program.

Just pass the apt variables, strcutures to the class etc as you were doing in the traditionl approach . Rest all is the same.

cl_gui_frontend_services=>gui_upload(

EXPORTING
FILENAME = SPACE
FILETYPE = 'ASC'
HAS_FIELD_SEPARATOR = SPACE
HEADER_LENGTH = 0
READ_BY_LINE = 'X'
DAT_MODE = SPACE
CODEPAGE = SPACE
IGNORE_CERR = ABAP_TRUE
REPLACEMENT = '#'
VIRUS_SCAN_PROFILE = VIRUS_SCAN_PROFILE
IMPORTING
FILELENGTH = FILELENGTH
HEADER = HEADER

CHANGING

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
NOT_SUPPORTED_BY_GUI = 17
ERROR_NO_GUI = 18

IF sy-subrc <> 0.

MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

We go for this OO as there are changes made to the SAP R/3 where most of the things are OO. The Operating system or Kernel of the SAP lastest veriosns support OO. For easy implementations and resuability we go for OO.

Hi,

Gui_upload : it is normal function module to upload the File and XL Sheet Data into Internal table.

Call function Gui_upload : this Functionality used in OOPS.
