“Using MergeOmatic to clean up duplicate records. I am finding that several are recurring as duplicates. Notes in Survivor record in RE document the merge. Some are even showing repeated merges. Still the non-survivor record remains in Raiser's Edge and the next time we run a scan the same records occur again. “
I have noticed this on occasion also. For me at least it appears to happen when the two records I have merged have conflicting Gift Aid (Tax) Declarations. Not found any other reason, and MOM does not flag it up as a merge error, so it looks like everything has been merged successfully.
This happened to us a lot during solicitor merging. The duplicate record would just end up being marked as inactive instead of getting merged.
