Due to the matching criteria being exact, you may already have a constituent in the database which is a partial match to the constituent you are importing but the plugin will not detect that constituent. In that case, you should edit the constituent record in The Raiser's Edge to make sure that it matches the information that you are importing (determined by your matching criteria in the EveryDayHero Plugin).
For example, you will get this exception if the following happens:
- Constituent Matching in the plugin is set to look at Sur/Org Name & Postcode with the option 'Add a constituent if no match is found' unselected
- The import file contains the surname Doe with the postcode of G22LW
- The Raiser's Edge record contains the surname of Doe with no postcode on the record
We are working with our products team to look into the option in the future to make this exception more detailed to the problem.
