Some of the Common Errors in UCCHECK and their resolution

Case - 1:

Error : Upload/Ws_Upload and Download/Ws_Download are obsolete, since they are not Unicode-enabled; use the class cl_gui_frontend_services

Cause : From Version ECC6.0 (Unicode complaint environment), the Function Mod-ules UPLOAD / WS_UPLOAD / DOWNLOAD / WS_DOWNLOAD has become obso-lete. In replacement of these Function Modules, we have GUI_UPLOAD / GUI_DOWNLOAD.

Solution: All the UPLOAD / WS_UPLOAD function modules need to be replaced with GUI_UPLOAD FM and all the DOWNLOAD / WS_DOWNLOAD with the GUI_DOWNLOAD function modules.

For replacing WS_UPLOAD :

*\ call function 'WS_UPLOAD'
*\ exporting
*\ filename = p_filel
*\ filetype = 'DAT' "'ASC' "'DAT'
*\ tables
*\ data_tab = record
*\ exceptions

ENDIF.

Clear: L_P_FILEL.

*} REPLACE


Note - 1 : The parameter FILENAME in GUI_UPLOAD is of type STRING for version ECC6.0. In 4.6C version (Non Unicode complaint environment), for the above code, ex-port parameter filename in UPLOAD / WS_UPLOAD was of data type “Character”. This need to be taken care of otherwise if an Extended Syntax Check is performed using the transaction SLIN, there would bet a Call Function Interface Error because of this. So to avoid that, one needs to declare a variable L_P_FILEL of type STRING and assign-ing that to the Parameter FILENAME. Also it’s better to have file type ‘ASC’.

For replacing UPLOAD :

PARAMETERS: I_NFILE LIKE RLGRAP-FILENAME DEFAULT
'c:\fi\docgen.prn'.

Note : Please make sure that default location is given if its not then dont use default file-name parameter in your Function module.

So we will be using the method ` GUI_UPLOAD` of the class `CL_GUI_FRONTEND_SERVICES`. Now in 4.6, while using FM UPLOAD, a pop-up used to appear, prompting you to get/locate the path of the file. To get the same function-ality in GUI_UPLOAD use code as below-


data: ft type filetable,
rc type i,

l_i_nfile_temp type string.

clear: l_i_nfile_temp, rc, l_ft, l_i_nfile.

For replacing DOWNLOAD :

DOWNLOAD is obsolete function module for storing SAP data in a file in the file sys-tem of the presentation server.

So we will be using the method `GUI_DOWNLOAD` of the class `CL_GUI_FRONTEND_SERVICES`. Now in 4.6, while using FM DOWNLOAD, a pop-up used to appear, prompting you to to put the path to save the file. To get the same functionality in GUI_DOWNLOAD use code as below-
