Autocomplete Rule to prevent assignment update on the same date as the latest update

Summary:

Hi there, just wondering if anyone had created a rule that would prevent a line manager from submitting an assignment change/transfer using the same effective date as the latest update on the assignment.

Example - Employee has an update on their assignment effective 20-SEPT-2022, the Line Manager attempts to put through a Transfer using the effective date 20-SEPT-2022, the autocomplete rule would prevent this and generate an error
