• What is the cause and solution for SAP error message FDUKS001 - File end or end of data entry reached unexpectedly ?

  The SAP error message FDUKS001 ("File end or end of data entry reached unexpectedly") typically occurs during the processing of data files, particularly when using the SAP Data Transfer Workbench or during file uploads. This error indicates that the system has encountered an unexpected end of the data file, which can happen for several reasons.
  Causes:
  
  Incomplete Data File: The file being uploaded may be incomplete or truncated, meaning that it does not contain all the expected data entries.
  Incorrect File Format: The file format may not match the expected format required by SAP. For example, if the file is supposed to be in CSV format but is in a different format, it can lead to this error.
  Data Entry Errors: There may be issues with the data entries themselves, such as missing fields or incorrect delimiters.
  File Encoding Issues: The file may be encoded in a format that SAP cannot read properly (e.g., UTF-16 instead of UTF-8).
  End of File Marker: The file may not have the proper end-of-file marker, leading the system to believe that it has reached the end of the data prematurely.
  
  Solutions:
  
  Check File Completeness: Ensure that the file you are trying to upload is complete and not truncated. You can do this by opening the file in a text editor or spreadsheet application to verify its contents.
  Verify File Format: Make sure that the file is in the correct format as required by SAP. If it is supposed to be a CSV file, ensure that it is saved correctly as a CSV.
  Review Data Entries: Check the data entries for any missing fields or incorrect formatting. Ensure that all required fields are populated and that the data adheres to the expected structure.
  Check Encoding: Ensure that the file is saved with the correct encoding (usually UTF-8). You can change the encoding in your text editor or spreadsheet application.
  Use SAP Tools: If you are using a specific SAP tool for data upload, refer to the documentation for that tool to ensure you are following the correct procedures and formats.
  Test with Sample Data: If possible, try uploading a smaller sample file that you know is correctly formatted to see if the issue persists. This can help isolate whether the problem is with the specific file or the upload process itself.
