Dedupe module includes the ability to mass merge duplicate groups based on a confidence level (the certainly that the matched records are duplicates). All duplicate records are assigned a match confidence score of between 1-100. The higher the score, the higher the probability that the records within the groups are genuine duplicates. Match confidence displayed on the group is the average match confidence of the grouped records.
Tip: We recommend that you review records inside groups at confidence time before using Mass Merge.
To run a mass merge task, select the MASS MERGE button from the duplicate group list view.
In the displayed window, use the dual confidence slider to select a confidence range (for example, only merge groups between 80–95%). This provides finer control than the old single slider.
You may also use tags to filter the merge. Tags can be used to include or exclude matched groups from mass merge.
Good to Know: Tags work in conjunction with the Match Confidence setting and will only be applied to groups with a match confidence above the set limit. You can also request AI recommendations in bulk. Mass AI Recommendations provide inline explanations and use colored tags to suggest whether to merge, unmatch, link, or split groups.
You can also apply a group-size filter to target only duplicate groups of a certain size (for example, groups of 2 records, or 10+ records). This helps focus mass merges on the most manageable sets.
Mass-action dialogs now display an estimated record count next to each filter, so you can preview how many records will be affected before running the merge.
