Field Expressions: transform source data before loaded into target. For example, mapping multiple source fields to single target field. Convert data values or performing data clean-up (trimming trailing blank spaces, etc).

Best Practice: Use field-level expression to convert the data
Create a field expression: Open existing task > Field Mapping Step on target step, Actions icon. Be sure to validate expression.
