  Cause:
  This error usually arises when there is an attempt to collect frequent value statistics on a column that is not of a numeric type.

  Adjust the Statistics Collection Command: If you are using a specific command or transaction to collect statistics, ensure that it is correctly configured to handle the data types of the columns involved.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific version you are using to understand the requirements and limitations of the statistics collection process.
  
  
  Use Alternative Approaches: If frequent value statistics are not applicable for the column in question, you may need to explore other types of statistics that can be collected for non-numeric columns.
