We have a lot of contacts in CRM 2011 which are imported to support a legacy application. All these contacts have a field which is set to be true to indicate that we don't show these on any of the views.
I am looking at a way to exclude these from the Create/Update duplicate detection that can be enabled on contacts.
These contacts are currently read only so for now my solution is to deactivate those records so I can use the 'exclude de-activated records' option.
This feels like a bit of a hack, is there not a way of telling the duplicate detection which sub set of contacts to check against?
