Understanding Start Date Calculation
After you enter all required work order information on the Work Order Details form (W48013A), the system calculates the start date for the work order. To calculate the start date of a work order based on the order's due date, the system uses level lead time or lead time per unit for an item that is defined on the Plant Manufacturing tab on the Additional System Info form (W41026D). The system calculates the start date using either the item's fixed lead time or its variable lead time. For process work orders, you use the effective dates to schedule the rate.
