• What is the cause and solution for SAP error message CNV_CMIS_A_20309 - Invalid File Type, Cannot proceed, Enter a CSV file ?

  The SAP error message CNV_CMIS_A_20309 indicates that the system is expecting a CSV (Comma-Separated Values) file format, but the file provided is of an invalid type or format. This error typically occurs during data migration or data upload processes where the system is configured to accept only specific file types.
  Cause:
  
  Incorrect File Format: The file you are trying to upload is not in CSV format. It could be in a different format such as Excel (.xls, .xlsx), text (.txt), or any other unsupported format.
  File Extension Mismatch: The file may have a .csv extension but is not actually formatted as a CSV file. For example, it might be saved in a different format or contain incompatible characters.
  Corrupted File: The file might be corrupted or improperly formatted, leading to the system being unable to read it as a valid CSV file.
  Encoding Issues: The file might be encoded in a format that is not supported by the SAP system (e.g., UTF-16 instead of UTF-8).
  
  Solution:
  
  Verify File Format: Ensure that the file you are trying to upload is indeed a CSV file. You can open it in a text editor (like Notepad) to check its contents. A valid CSV file should have data separated by commas.
  Re-save the File: If the file is in a different format (like Excel), open it in the appropriate application and save it as a CSV file. Make sure to select the correct CSV format when saving.
  Check File Encoding: Ensure that the file is saved with the correct encoding (preferably UTF-8). You can change the encoding when saving the file in applications like Notepad or Excel.
  Remove Special Characters: Check for any special characters or formatting that might not be compatible with the CSV format. Clean the data if necessary.
  Test with a Sample File: Create a simple CSV file with a few rows of data to test if the upload works. This can help determine if the issue is with the specific file you are using.
