  The SAP error message CNV_CMIS_A_20_FUNC109: Too many fields. Excel download not possible. typically occurs when you are trying to download data from an SAP system to Excel, and the number of fields (columns) in the dataset exceeds the limit that Excel can handle for a single download.
  Cause:
  
  Exceeding Excel Limits: Excel has a limit on the number of columns it can handle in a single worksheet. For Excel 2007 and later versions, this limit is 16,384 columns (from A to XFD). If your dataset exceeds this number, the download will fail.
  SAP Configuration: The configuration in the SAP system may also impose limits on the number of fields that can be exported at once.
  Data Structure: The structure of the data being exported may inherently have too many fields due to the nature of the report or query being executed.
  
  Solution:
  
  Reduce the Number of Fields: Modify your query or report to limit the number of fields being exported. You can do this by:
  
  Selecting only the necessary fields for your analysis.
  Using filters to reduce the dataset size.
  
  
  Split the Download: If you need to export all the data, consider splitting the download into multiple parts, each containing fewer fields.
  Use Alternative Formats: If the data is too large for Excel, consider exporting it in a different format, such as CSV or TXT, which may not have the same limitations.
  Check SAP Notes: Look for any relevant SAP Notes or updates that might address this issue. Sometimes, SAP releases patches or updates that can help with data export limitations.
  Consult with SAP Basis Team: If you are unsure about the configuration or limits set in your SAP system, consult with your SAP Basis team or system administrator for assistance.
  
  Related Information:
  
  Excel Limitations: Familiarize yourself with the limitations of the version of Excel you are using, as older versions have lower limits (e.g., Excel 2003 has a limit of 256 columns).
  SAP Transaction Codes: If you are using specific transaction codes to generate reports, check if there are options to customize the output format or field selection.
  Documentation: Review SAP documentation related to data export functionalities for best practices and guidelines.
  
  By following these steps, you should be able to resolve the error and successfully download your data from SAP to Excel.
