  The SAP error message FDT_EXPRESSIONS858 indicates that there is an issue with the mapping of a data object, specifically related to a timepoint type of datetime. This error typically arises in the context of SAP's Flexible Data Import (FDI) or Flexible Data Transformation (FDT) tools, where data mappings are defined for data transformation processes.
  Cause:
  The error can occur due to several reasons:
  
  Invalid Mapping: The mapping defined for the data object is incorrect or does not conform to the expected format for datetime values.
  Data Type Mismatch: The source data type does not match the expected target data type. For example, if the source is a string that does not represent a valid datetime format.
  Configuration Issues: There may be issues in the configuration of the data transformation process, such as missing or incorrect settings for the datetime fields.
  Data Quality Issues: The incoming data may contain invalid or unexpected values that cannot be converted to a datetime format.
  
  Solution:

  Data Quality Check:
  
  Inspect the incoming data for any invalid datetime values. Cleanse the data if necessary to ensure that all datetime values are valid.
  
  
  
  Test with Sample Data:
  
  If possible, test the mapping with a small set of sample data to identify if the issue persists. This can help isolate the problem.
