Difference between ECC 6.0 and earlier versions

Question

Hi,
one of the difference between ECC 6.0 and earlier versions is that instead 'WS_UPLOAD'  and 'WS_DOWNLOAD' in ECC we should use 'GUI_UPLOAD' and 'GUI_DOWNLOAD'  respectively.
(of course SPDD and SPRO tcodes is known by everone i suppose)
Similarly can u all put down some differences here, atleast one entry by each, I think we can make a good docu. I have searched the net for the differences but could not get much, so by each of us contributing one each, it would become good docu..for all of us.
Thanx in advance

Answer 1

Unicode Errors Encountered and their Solutions
E1. In u201CTEXT MODEu201D the u201CENCODINGu201D addition must be specified.
     Error:
     OPEN DATASET FILE FOR OUTPUT IN TEXT MODE.
     Solution:
     OPEN DATASET FILE FOR OUTPUT IN LEGACY TEXT MODE.
E2. In Unicode, DESCRIBE DISTANCE can only be used with the IN BYTE MODE  or  IN
      CHARACTER MODE  addition.
     Error:
     DESCRIBE DISTANCE  BETWEEN T_KOMK AND T_KOMK-HIEBO01 INTO BPOS.
     Solution:
DESCRIBE DISTANCE  BETWEEN T_KOMK AND T_KOMK-HIENR01 INTO BPOS
IN CHARACTER MODE.
E3. u201CUSR02-UFLAGu201D must be a byte-type field (Typ X or XSTRING )
     Error:
     IF USR02-UFLAG O YULOCK.
     Solution:  Since the data type of USR02-UFLAG is type INT and is compared with data type
                X u2013 Hence the error. So we  define a new variable ZULOCK and assign the
                value of USR02-UFLAG to ZULOCK.
              New variable             
              DATA: ZULOCK(1) TYPE X.   "APBRP00
              Assign value               
                            ZULOCK = USR02-UFLAG.
        Compare -
               IF ZULOCK = YULOCK.   u201Creplace IF USR02-UFLAG O YULOCK.
E4.  HT cannot be converted to a Character type field
Error :
WRITE ht TO t_data+10(2).
Solution : Since the data type of ht is a type u2018Xu2019 and the data is been transfer to
         t_data which has a data type u2018Cu2019. value of one data type cannot be copy to
         another data type where one of them is type string .Hence the error occur,
         so the data type of ht is been change to Type u2018Cu2019
     OR
           A Tab ( value 09 ) is introduced as part of the row. The value 09 is not converted in Unicode environment. Instead we need to use class
     Error:
          DATA: BEGIN OF ht,
               x(1) TYPE x VALUE '09',
          END OF ht.
     Solution:
              Define Class after the Tables definition.
                   CLASS cl_abap_char_utilities DEFINITION LOAD.
              Data Defination :  Comment internal table HT and define a variable HT type C.
       *   Insert + APRIA00 05/02/2007 Unicode project
       *   DATA: BEGIN OF ht,
     *         x(1) TYPE x VALUE '09'
       *   END OF ht.
     *   Insert - APRIA00 05/02/2007 Unicode project
       DATA HT type C.
       Before using HT assign Horizontal tab.
                 Ht = CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB.  
E5.  In Unicode programs the u201C#u201D cannot appear in names, as it is does here in the name    u201C#LINESu201D
     Error :
     #LINES                 TYPE I,
     Solution : Since the # is used in the start of name, it is not allowed. We need to
              remove it. 
     Solution for the above
     V_LINES                 TYPE I,
E6. In u201CTEXT MODEu201D the u201CENCODINGu201D addition must be specified as well as the addition was required FOR OUTPUT,FOR INPUT, FOR APPENDING OR FOR UPDATE was expected.
     Error:
     OPEN DATASET PATH_NAME IN TEXT MODE.
     Solution:
     Download =     OPEN DATASET PATH_NAME FOR OUTPUT IN LEGACY TEXT MODE.
     Upload        =  OPEN DATASET AUSZUG-FILE IN TEXT MODE FOR INPUT ENCODING DEFAULT.
E7. u201CTABu201D must be a character-type data object( data type C,N, D, T or String). Field string)    
     Error:
            data: begin of tab,                   "Excel Parameter Split at TAB
        t type x value '09',          "Tabulator
       end of tab.
            concatenate 'Material' 'Package Status'
                into z_download-line separated by tab.
            ( In the above command  the two field are to be separated with a horizontal Tab. The earlier      way of assigning the tab value u201809u2019 will not work in Unicode environment.
     Solution:
     Define a  class just after the Table defination.
          CLASS cl_abap_char_utilities DEFINITION LOAD.
            Define  variable Tab as shown below :
          Data : TAB           TYPE C.
     Before the concatenate statement assign the value of Tab using pre-defined attributes.
          TAB = CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB.
E8. Upload/Ws_Upload and Download/Ws_Download are obsolete, since they are not Unicode-
      enabled; use the class cl_gui_frontend_services     
     Error-1:  Function WS_DOWNLOAD is obsolete in Unicode environment.
            call function 'WS_DOWNLOAD'
                 exporting
                      filename = zfilename
                 tables
                      data_tab = z_download.
     Solutions-1: Instead of WS_DOWNLOAD use  GUI_DOWNLOAD.
CALL FUNCTION 'GUI_DOWNLOAD'

*   BIN_FILESIZE                  =
    FILENAME                      = zfilename
  TABLES
    DATA_TAB                      = z_download.
E9.  The "/" character is reserved for identification of namespaces. It must be entered twice.
        The name  of a namespace must be at least 3 characters long.
     Error :      
                 U/N(3)        TYPE C,  "U/N    --> ERSETZT DURCH SPACE
     Solution :
     * Special character can not be used to define a data variable
     *      U/N(3)        TYPE C,  "U/N    --> ERSETZT DURCH SPACE
              U_N(3)        TYPE C,  "U/N    --> ERSETZT DURCH SPACE
     * Insert - APSUS02 07/02/2007 Unicode Project
E10.  "LP_TAB" and "CS_TAB" are not mutually convertible. In Unicode programs,
         "LP_TAB" must have the same structure layout as "CS_TAB", independent of the length
         of a Unicode character.
     Error : This error is encountered when data from one internal table is copied to another
                         internal table which different structure. In this case its LP_TAB & CS_TAB.
                 LP_TAB[] = CS_TAB[].
     Solution :
          * Replace + APSUS02 07/02/2007  Unicode Project
*   LP_TAB[] = CS_TAB[].
              move-corresponding CS_TAB to LP_TAB.
          * Replace + APSUS02 07/02/2007  Unicode Project
E11.  Could not specify the access range automatically. This means that you need a RANGE
          addition.          
     Error :  Range need to be specified as an addition to the command.
            DO 4 TIMES VARYING HELP_CHAR FROM ABCD(1) NEXT ABCD+1(1).
           Solution : 
            DO 4 TIMES VARYING HELP_CHAR FROM ABCD(1) NEXT ABCD+1(1)
          * Insert + APSUS02 07/02/2007  Unicode Project.
                                                      RANGE ABCD+0(4).
* Insert - APSUS02 07/02/2007  Unicode Project.
E12 .  Processing Terminated Error code: Error in opening /
                                          Path not found when downloading to Unix directory.
     Error : PARAMETER: outfile(92) DEFAULT
              '/CP/interface/NPP/data/MX/cbslaprcpts'
                    LOWER CASE,
               kmxmstrd AS CHECKBOX.
            This error is encountered when the path is missing. The above path is related to CCP.
     Solution:  For testing purpose comment the original path and replace it with
                                 /CP/interface/CCD/Unicode_test/ 
E13.    Upload/Ws_Upload and Download/Ws_Download are obsolete, since they are not                                                                       Unicode- enabled; use the class cl_gui_frontend_services
     Error: Function WS_UPLOAD is obsolete in Unicode environment. (During UCCHECK)
               Call function 'WS_UPLOAD'
       Exporting
            Filename                = zfilename
            Filetype                = u2018DATu2019

            unknown_error           = 7
            gui_refuse_filetransfer = 8
            others                  = 9.
     Solution: Instead of WS_UPLOAD use TEXT_CONVERT_XLS_TO_SAP. Do not use temporary file put the file name as it is.
1) First define a type pool and a variable of type truxs_t_text_data.
TYPE-POOLS: truxs.
DATA: it_raw TYPE truxs_t_text_data.
     2) Use this it_raw in the function module in parameter i_tab_raw_data. Put file name and the internal table in the function module.
CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP'
    EXPORTING
*     I_FIELD_SEPERATOR        =

      OTHERS                   = 2.
     Comment u201Ci_line headeru201D. It takes the first/ header line of the file which is to be uploaded.
Put  square brackets after internal table as shown above.
E14.    CURSORHOLD may not be converted into a number.
     Error:  GET CURSOR LINE CURSORHOLD VALUE CURSOR_HOLD.
     Solution: In the declaration part of CURSORHOLD, one field is of u2018Pu2019 type and one field is of u2018Iu2019 type, which is not allowed in Unicode environment.So change the the type of it to NUMC.
