  Causes of RSTT0162

  Data Type Mismatch: If the data types of the fields in the internal structure do not match those in the reporting structure, it can lead to transformation errors.
  
  
  Missing Fields: If the transformation logic expects certain fields to be present in the internal structure but they are missing, this can trigger the error.
  
  
  Inconsistent Data: If the data being transformed contains inconsistencies or invalid values that do not conform to the expected format, it can cause the transformation to fail.
