two primary assignments for one employee

Summary:

We have just found an employee that has two primary assignments.

These were loaded on our initial data migration.

We cannot end these records because of this.

Is there a hdl or a way to end one of these assignments so we can get the record straight?

Content (required):

Assignment 1 was the initial primary assignment.

Assignment 2 and 3 were data loaded and were both made the primary, replacing assignment 1 that ended.

Is there anyone that can help resolve this problem?
