Manufacturing: Enhancements in Finite Production Scheduling

In MYOB Acumatica Manufacturing Edition, the constraint date acts as a limiting factor in planning, influencing when production activities should start or finish. The production scheduling algorithm attempts to schedule a production order as close to its constraint date as possible, factoring in available capacity and material availability (if it is configured).

When a production order cannot be scheduled to meet the constraint date, a production planning manager reviews the scheduling outcomes to determine which production orders can be rescheduled, which orders can be delayed, and when overtime is required to increase capacity.

In previous versions of MYOB Acumatica, users could encounter unexpected results when the system could not backward-schedule a production order based on its constraint date (that is, when the Finish On scheduling method was used and the start date calculated based on the constraint date was in the past). In this case, the system switched from backward scheduling to forward scheduling (that is, the scheduling method was changed to Start On) and changed the constraint date to the current date (or to a future date, if other production orders were competing for the same work center resources). The information about the original constraint date and scheduling direction was lost, which made it challenging for the production planning manager to compare the calculated production start and end dates with the desired constraint date.

In MYOB Acumatica 2025.1, if a user is attempting to schedule a production order on the Rough Cut Planning (AM501000), Production Order Maintenance (AM201500), or Production Schedule Board (AM215555) form and the production order cannot be scheduled backward to meet the constraint date, the system does the following:

• Attempts to schedule the production order forward by assigning the start date to the current date or a future date based on the load of the work centers involved. The constraint date and the Finish On scheduling method are preserved, which helps the production planning manager to compare the calculated earliest end date with the original constraint date.
• Displays a message indicating that the production order has been scheduled forward instead of backward. A similar message is also displayed on the Events tab of the Production Order Maintenance form.

Additionally, the system now displays a warning message if a production order cannot be scheduled because its constraint date is outside the scheduling window of 120 days. Previously, the scheduling algorithm ignored such production orders, but no notification was shown to the user.
