Map across the fields which should be imported. Note that not all fields in Raiser’s Edge can be imported into in a meaningful way so these have been removed from the fields available.
You are also able to specify whether or not a blank value should overwrite a populated value. By default the blank will not overwrite the populated value but it may be that this is required in which case you can set this on a field by field basis. Note that the line will still appear in the review screen showing a blank but that it will not actually overwrite the populated value.
