How to fetch element entries based on Assignment_Id instead of Person_id

We have encountered an issue in the current HCM Extract where an employee has multiple active assignments, but the extract is returning all assignment numbers—even though the element entry is associated with only one specific assignment.

Current Behavior

The affected employee has two active assignments. The element entry has been added only for one assignment. However, in the extract output, both assignment numbers appear.

Expected Behavior

The extract should return only the assignment for which the element entry actually exists, and exclude all other active assignments of the employee.
