Excel attachment not attached in Workflow

[arghadip kar]

Hi
 
I have a strange case where the excel attachment that I am retriveing from the Portal is not getting attached to workflow properly. the Bytesize is getting truncated with a multiple of 255. Here is the small portion of the code attached.
 
* retrieve the file from app server that was saved by portal
   open dataset v_filename for input in binary mode.
   if sy-subrc eq 0.
     do.
       read dataset v_filename into i_solix.
       if sy-subrc eq 0.
         append i_solix.
       else.
         exit.
       endif.
     enddo.
     close dataset v_filename.
   endif.
* get the index of the binary table
  clear v_tab_lines.
  describe table i_solix lines v_tab_lines.  "get index
  read table i_solix into v_wa_solix index v_tab_lines.
                                           "read last line into buffer
* determine the total file size in birnary format
  v_doc_size = ( 255 * v_tab_lines ).    "whole lines
* convert binary to xstring
    call function 'SCMS_BINARY_TO_XSTRING'
      exporting
        input_length = v_doc_size
     importing
       buffer        = v_xstring
Tables
             binary_tab   = i_solix.
 document file attributes
 get the extension name
  v_offset = strlen( v_docname_only ) - 3.
  v_doc_extension = v_docname_only+v_offset(3).
  v_att_header-file_type      = 'B'.
  v_att_header-file_name      = v_docname_only.
  v_att_header-file_extension = v_doc_extension.
  v_att_header-language       = sy-langu.
   call function 'SAP_WAPI_ATTACHMENT_ADD'
     exporting
       workitem_id         = v_workitemid
       att_header          = v_att_header
     ATT_TXT             =
     att_bin             = v_xstring
     DOCUMENT_OWNER      = SY-UNAME
     LANGUAGE            = SY-LANGU
     DO_COMMIT           = 'X'
   importing
   *     RETURN_CODE         =
      att_id              = v_att_id
*   TABLES
*     MESSAGE_LINES       =
*     MESSAGE_STRUCT      =
          .
* pass attachment id and internal document number for SOFM
 swc_set_element container 'ATT_ID' v_att_id.
 swc_set_element container 'SOFM'   v_att_id-doc_id.
  endif.
 
Suppose the Byte size is 18992 the v_doc_size is 18870. Can you please check what is the issue.When we try to read the attachment we get the file is damaged and on cancelling the file appears but the byte size is truncated.
 
Thanks
