Let us consider a subcontract order whose subcontract start date is on the 26/06.
- If the reorder lead-time is 7 days, the material requirement date will be calculated on the 03/07 (26/06 + 7).
- If the reorder lead-time is -7 days, the material requirement date will be calculated on the 19/06 (26/06 - 7).
