如何为质量通知单创建HEX格式附件？已有下载代码求指导

Great question! You're already halfway there with your existing code to fetch HEX content—let's adapt that to attach the file to a quality notification using SAP's Office APIs. Here's a step-by-step breakdown and working example:

Key Background #

First, a quick recap: Quality notifications (QMNUM) in SAP are tied to the business object BUS2078. Attaching a file requires two core steps:

1. Create the document in SAP Office using SO_DOCUMENT_INSERT_API1
2. Link that SAP Office document to the quality notification business object with SO_OBJECT_ATTACH_API1

Your existing HEXCONT (a SOLIX type table) is exactly the format SO_DOCUMENT_INSERT_API1 expects for binary content—no extra conversion is needed if you retain this table from your download logic.

Working Code Example #

Here's how to extend your current logic to insert and link the attachment:

METHOD INSERT_ATTACHMENT_TO_QNOTIFICATION.
  DATA:
    ls_docdata    TYPE sofolenti1,
    lt_contents   TYPE TABLE OF solix,
    ls_doc_key    TYPE soodk,
    ls_bor        TYPE sosubi,
    lv_qmnum      TYPE qmnum VALUE 'Q1000001', " Replace with your target QMNUM
    lv_filename   TYPE string VALUE 'invoice.pdf', " Your file name
    lv_filetype   TYPE string VALUE 'PDF'. " File extension

  " Step 1: Fetch the HEX content (reuse your existing method)
  CALL METHOD me->get_single_attachment_content
    EXPORTING
      file_id = 'YOUR_SOURCE_FILE_ID' " Replace with the file ID you're fetching from
    IMPORTING
      ev_return = DATA(lv_xstring).

  " Optional: If you only have the XSTRING, convert it back to SOLIX table
  " Skip this if you retained the lt_contents table from your download method
  CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
    EXPORTING
      buffer        = lv_xstring
    TABLES
      binary_tab    = lt_contents
    EXCEPTIONS
      failed        = 1
      OTHERS        = 2.
  IF sy-subrc <> 0.
    MESSAGE 'Failed to convert XSTRING to binary format' TYPE 'E' RAISING CONVERSION_ERROR.
  ENDIF.

  " Step 2: Populate document metadata for SAP Office
  ls_docdata-obj_name = 'QM_NOTIF_ATTACHMENT'. " Internal name (can be any string)
  ls_docdata-obj_descr = lv_filename. " Visible description in attachments
  ls_docdata-file_ext = lv_filetype. " File extension
  ls_docdata-doc_size = lines( lt_contents ) * 255. " Calculate total size (SOLIX line = 255 bytes)

  " Step 3: Insert the document into SAP Office
  CALL FUNCTION 'SO_DOCUMENT_INSERT_API1'
    EXPORTING
      folder_id              = CONV soodk( 'INBOX' ) " Use INBOX or a custom folder ID
      document_data          = ls_docdata
      document_type          = 'BINARY' " Use 'TEXT' for plain text files
    IMPORTING
      document_id            = ls_doc_key
    TABLES
      contents_hex           = lt_contents
    EXCEPTIONS
      folder_not_exist       = 1
      document_type_not_exist = 2
      operation_no_authorization = 3
      parameter_error        = 4
      x_error                = 5
      OTHERS                 = 6.
  IF sy-subrc <> 0.
    MESSAGE 'Failed to create SAP Office document' TYPE 'E' RAISING DOCUMENT_INSERT_ERROR.
  ENDIF.

  " Step 4: Link the document to the Quality Notification
  ls_bor-objtype = 'BUS2078'. " Business Object Type for Quality Notifications
  ls_bor-objkey = lv_qmnum. " Your target Quality Notification Number
  ls_bor-objcat = 'BO'.

  CALL FUNCTION 'SO_OBJECT_ATTACH_API1'
    EXPORTING
      object_id              = ls_doc_key
      bor_object             = ls_bor
    EXCEPTIONS
      object_not_exist       = 1
      bor_object_not_exist   = 2
      operation_no_authorization = 3
      parameter_error        = 4
      x_error                = 5
      OTHERS                 = 6.
  IF sy-subrc <> 0.
    MESSAGE 'Failed to attach document to Quality Notification' TYPE 'E' RAISING ATTACH_LINK_ERROR.
  ENDIF.

ENDMETHOD.

Critical Notes #

• Reuse the SOLIX table: If you modify your GET_SINGLE_ATTACHMENT_CONTENT method to return the HEXCONT table directly, you can skip the XSTRING-to-SOLIX conversion step entirely—this is more efficient.
• Folder ID: INBOX works for most cases, but if you need to store attachments in a specific folder, use SO_FOLDER_LIST_API1 to fetch the folder ID.
• Permissions: Ensure your user has authorization for:
  • Creating SAP Office documents (transaction SO01 and authorization objects S_O_DOC/S_O_FOLD)
  • Modifying quality notifications (authorization object QMAUTH)
• File Types: Use document_type = 'TEXT' for plain text files (like TXT, CSV) and 'BINARY' for all other formats (PDF, Excel, images).
