Symptoms

When there is a firm Work Order (P48013) with a Start Date earlier than when there is demand, intermittently MRP (R3482 or R3483) will create an Expedite Message (Type E) even though the Recommended Start Date is later and therefore should make it a Defer message.

Steps:
1. Observe a Work Order's Start Date (P48013).
2. Create demand (e.g., Sales Order, P4210 or Forecast, P3460) for a date beyond the Work Order's Start Date.
3. Run MRP (R3482 or R3483).
4. Review Detail Messages (P3411). Notice there is a Message Type E (Expedite) message even though MRP is suggesting a later date. This should be a Defer Message.
