Based on what I assume in the background is the Supply Date for the Header (7/14/20xx), the calculated Start Date for either this part's Interim Order or for a lower-level part's interim order is June 12, but the phase in date for the routing revision of the suspect part is after June 12.

Backdate the phase in date of the routing revision of the suspect part to a date prior to June 12 (e.g., 1/1/2025).
