When entering Constituent information in Batch, users have the option of using a FinderNumber to track giving from Appeal Mailings and Marketing Efforts. When Constituents are not matching to their FinderNumbers users will see the error: The Constituent does not Match to this Finder. When importing revenue with finder numbers this error does not surface. Instead Constituent information is overwritten when importing gifts with finder numbers that do not belong to Constituents in the import file.
We're currently evaluating this issue for a fix in a future patch or service pack.
