How do I get rid of duplicate resources on my instance?

Sometimes the same resource is inadvertently added more than once on PPO. Most commonly this happens because the administrator fails to disable the global resource filter and verify that the resource does not already exist as an inactive resource before adding another record. Having duplicate resources causes confusion, especially if the resource is also a user on PPO.

The solution is twofold:

  1. We have to correct the duplicates that have already been added; and
  2. We have to prevent duplicates from being added in the future.

Current duplicates

The problem with the existing duplicates is that some Tasks / Issues / Risks may be assigned to the original resource and others may be assigned to the duplicate. The first step in correcting the duplicates is to first ensure all items on the system are assigned to the same resource record. The easiest way to do this would be to edit one of the resource records and put a 1 at the end of the person’s first name:


Then go to the Task List pageIssue List page and Risk List page and filter the page to show the items assigned to the duplicate resource (in this example, the resource with the 1 at the end of his name). Edit these records and assign them to the resource without the 1.
Once all of the Tasks, Issues and Risks have been reassigned to the original resource, the Home Page for the duplicate resource should be empty.
You can then edit the duplicate resource's record and mark them as inactive, causing them to be hidden from all resource lists.

If the resource in question is a user on PPO, you will have to check the user record for the resource to ensure it is linked to the correct (original) resource.
If the user is linked to the duplicate record (in this example, the resource with the 1 at the end of his name) simply edit the user record and change the resourceto the correct (original) resource.

Preventing duplicates

There are two options in terms of prevention:

  1. Limit the users in terms of who has access to add resources. For some organisations it would be viable to only allow the PPO Administrators to load resources. The administrator can then ensure the resource they are creating is not a duplicate, before continuing. If the resource does exist, but as an inactive resource, the PPO Administrator should mark the resource record as active.
  2. We can implement a custom validation rule that prevents users from adding a second resource with the same e-mail address. This validation rule is run across active and inactive resources, and searches whether the resource's email address you are trying to add is unique. If it is unique, the system will allow the new resource to be added. If it is not unique, the system will prompt you to search for the resource under the Inactive resources and mark them as active. This would prevent duplicate resources from being added.
    All PPO instances post July 2020 will be provisioned with this business rule already in place.

An exception to the rule

PPO Administrators can add exceptions to the validation rule if required.  This is typically used to allow certain dummy e-mail addresses e.g. which is associated with multiple resource records.
