This error suggests that there is an issue with converting data from one format to another, particularly when moving data into a field that has specific data type requirements.
  Causes:
  
  Data Type Mismatch: The data being processed does not match the expected data type of the target field. For example, trying to move a string into a numeric field.
  Invalid Data Format: The data may be in an incorrect format, such as date formats or currency formats that do not align with the expected input.

  Handle Null Values: Implement checks in your code to handle null or empty values appropriately before moving them to the target field.
  Adjust Field Lengths: If the data exceeds the field length, consider truncating the data or increasing the field length if possible.
