Frequently Asked Questions
How many matching rules can the Potential Duplicates component use?
Up to 5 matching rules per object, with at most 1 cross-object matching rule. Selection is saved per object, so configuring rules for Contact applies to every Contact record page where the component is placed.
Why are the results different from the scheduled duplicate report?
The component evaluates rules in real time against the current record data, while scheduled reports may use cached results from the last scan. Different rules may also be selected in each context.
Can read-only users merge duplicates from the component?
No. Users with the No Duplicates Read Only permission set see the component and the duplicate list, but the Merge button and the gear icon are hidden. Only users with the admin permission set can merge or change rule selection.
Does the component slow down record page loading?
It can if you select many matching rules or rules that scan very large datasets. Limit to focused, fast rules — typically 2 to 3 — for good page performance, especially on high-traffic objects.
