Problem attach document with the FileUpload UI.

Question

I am trying to attach a document to a CRM Notification from application Web Dynpro for ABAP, I have build a FM that includes the method
cl_crm_documents=>create_with_file
When I test the FM from SE37 transaction, I am able to attach a file from a local disk succesfully. But If I call this FM from Web Dynpro, trying to do the same operation, document cannot attach to notification and Method returns the following error: “Error loading file ” (Class of message CRM_DOCUMENTS and number 100).
Thanks in advance.

aqui llamamos a este método porque de lo contrario el sistema crea el anexo con el nombre que

Hi,
you can use below steps,
1. Create attribute file_content of type xstring and bind it to data attribute of FileUpload UI .
2.Put the button Upload next to your FileUpload UI element and write action upload.
3. in action, read the attribute file_content and pass it to below code
Convert XString to String
  CALL METHOD cl_abap_conv_in_ce=>create
    EXPORTING
      input       = file_content
      encoding    = 'UTF-8'
      replacement = '?'
      ignore_cerr = abap_true
    RECEIVING
      conv        = loc_conv.
*Read the file contents
  TRY.
      CALL METHOD loc_conv->read
        IMPORTING
          data = file_content_string
    CATCH cx_sy_conversion_codepage.
*-- Should ignore errors in code conversions
    CATCH cx_sy_codepage_converter_init.
*-- Should ignore errors in code conversions
    CATCH cx_parameter_invalid_type.
    CATCH cx_parameter_invalid_range.
  ENDTRY.
4. After that u may want to put the contents into internal table so use
  SPLIT file_content string AT crlf INTO TABLE itstring_tab.
5. At last, fill the internal table
loop AT it_string_tab INTO wa_string.
    CHECK sy-tabix GT 1 .    "skip the first line
    SPLIT wa_string AT ',' INTO .....
endloop.
here in my code i have splitted the contents at comma as i had .csv file . so based on file type u can split it and fill internal table.
hope this will help you.
