Find Duplicate Contacts
Find Duplicate Contacts searches through your existing contacts to identify 'suspected' duplicate records - using the Duplicate Contact Rules which you've configured for your site.
Click Use Rule next to the type of contact for which you want to look for duplicates. You will get a list of contacts which are suspected duplicates. You can then select a contact and compare it to the suspected duplicate by viewing the differences in the field values.
If you determine that the contacts are actually duplicates, you can merge the duplicate contact information INTO the "main contact". All activities and related information can be merged if you so choose.
 | The duplicate contact will be automatically deleted after it's information has been merged. |
 | Dedupe by Group to Avoid Timeout Errors
If you have a large number of contacts and/or your server's PHP maximum execution time is set too low - you may get the following error when during this process:
Fatal error: Maximum execution time of 30 seconds exceeded
One work-around is to tell CiviCRM to dedupe your contacts "one group at a time". To do this, add a group ID (&gid=) to the end of the URL.
EXAMPLE: To find duplicate contacts in group 3:
NOTE: This will only work with Standard Groups - i.e. it will not work with Smart Groups. |
