A record with the value PersonDEO already exists. Enter a unique value.

Summary:

During Open Enrollment, employees are receiving the following error when attempting to add a new dependent in Oracle Fusion:

“A record with the value PersonDEO already exists. Enter a unique value.”

The error prevents employees from completing the process of adding a new dependent.

Content (please ensure you mask any confidential information):

The error is under People to Cover within the Open life event, and only encountered in PROD (error is not happening in the lower environments)

I tried adding the new dependent from the actual People to Cover screen before going into the enrollment event. I also tried adding the new dependent inside the enrollment event. Both produced the same error.
