Does NetSuite Duplicate Record Merging Trigger Scripts?

NetSuite's built-in duplicate record merging functionality does not trigger any script events. Therefore, custom scripts cannot be directly executed when a merge occurs. The most effective method to identify records that have been the master of a merge is to create a saved search.

1. Create a new saved search for the relevant record type (e.g., Customer, Contact, Lead).

2. Add a filter: [System Notes : New Value] starts with 'Merged with duplicates'.

3. Include a column with any System Notes join field to display details about the merge.This saved search will return all records of the specified type that have acted as the master in a merge operation. The value of the System Notes : New Value field follows specific rules:If the merge was with 1 duplicate only: 'Merged with duplicates: {internalid} {name}'If the merge was with more than one duplicate: 'Merged with duplicates: {internalid} {name}, {internalid} {name}...' (comma delimited)Important considerations regarding merged records and system notes:The record will have one system note line for each merge that was done where it was the masterIf the record has gone through a merge where it was not the master, there is no way to find the original merge(s) anymore as the system notes are deleted along with the record
