I need a way to run contribution data (in a .csv file) through the import process a second time without creating problems. I don't have available to me the file of rejected rows from the first import.

There are lots of options for handling dupes when contacts are imported, but for contributions there is only one choice:  Insert new contributions, or Update existing contributions. The explanation isn't clear about how dupes are handled. It reads


What happens if I choose "INSERT new contribution records" - and I import my file that's already been run through the import once? Will it assume all contributions are new, and end up creating duplicates for the ones that inserted the first time? (We don't want this.)

Or, what happens if I choose "UPDATE existing records," and it comes across contribution data that didn't import the first time, because of errors? Will those contribution records be skipped, since there is no existing record to update? (We don't want this either.)

Not sure how to proceed.
