Creates an exact copy of the selected field and is used to map any field from the source to multiple fields in the destination. This because field mapping is done one-to-one and not one-to-many.
There is no need to copy a field if the source field is used to map it to a field in the destination and for a transformation. Any field in the source can be used multiple times as input for any of the transformations.
Configuration
Field – Select the field from the source that will be copied
Field name – The name of the newly added field.
Notes – Optional description to describe the reason this transformation is added. Convenient for later reference.
