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.
