Question

Hi experts
I'm having a problem that I need to solve urgent, the point is FM GUI_DOWNLOAD is excuted perfectly with parameters:
        CALL FUNCTION 'GUI_DOWNLOAD'
          EXPORTING
            FILENAME                = 'C:test.xls'
            FILETYPE                = 'ASC'
            WRITE_FIELD_SEPARATOR   = 'X'
          TABLES
            DATA_TAB                = ti_salida2
          EXCEPTIONS
            FILE_WRITE_ERROR        = 1
            NO_BATCH                = 2
            GUI_REFUSE_FILETRANSFER = 3
            INVALID_TYPE            = 4
            NO_AUTHORITY            = 5
            UNKNOWN_ERROR           = 6
            HEADER_NOT_ALLOWED      = 7
            SEPARATOR_NOT_ALLOWED   = 8
            FILESIZE_NOT_ALLOWED    = 9
            HEADER_TOO_LONG         = 10
            DP_ERROR_CREATE         = 11
            DP_ERROR_SEND           = 12
            DP_ERROR_WRITE          = 13
            UNKNOWN_DP_ERROR        = 14

            DATAPROVIDER_EXCEPTION  = 20
            CONTROL_FLUSH_ERROR     = 21
            OTHERS                  = 22.
Excel output file is:
100000000000000000  BLOCK  ZC01 OFICNOR
... and must be like this:
100000000000000000598  BLOCK ZC01 OFICNOR
Which parameter I must change for this? I will appreciate any helpfull information because it's urgent.

Hi Gabriel
Values of internal table were assigned correctly during debug, problem is when FM is excecuted, exactly MATNR field.
If I don't put parameter WRITE_FIELD_SEPARATOR   = 'X' , value of MATNR is downloaded as I need.
