  Field Mismatch: The data types of the source and target fields may not match, leading to an inability to perform the required conversion.

  Go to the transformation in the SAP BW system and review the rules for the target field indicated in the error message.
  Ensure that a valid conversion type is specified for the target field.

  Verify Data Types:
