[GNC] CSV matching produces duplicates?

[David Cousens]

Elmar,
It is possible to do some limited tuning of the matching algorithm. Edit->
Preferences->Import although the adjustment of the parameters and what their
effects are is by no means intuitive or clear. The matching time window is hard
coded in so I regularly get matches to regularly repeated transactions in the
previous month when I am importing CSV data which is fortunately failry
infrequent these days. Particularly on CSV imports I check very carefully before
accepting GnuCash's matches. 

The OFX files have unique UUIDs on each transaction  whereas the CSV data
imports do not have unique identifiers that can be used to distinguish different
transactions and any hand entered entries will not have the external UUID
assigned by the bank.  The matcher is not prefect. but it does generally work
reasonably.
