Acceptable Early Days Delivery

You can define a number of days that you allow orders to arrive before they are needed. The Acceptable Early Days item attribute is defined in Oracle Inventory. Oracle Master Scheduling/MRP and Supply Chain Planning does not generate a reschedule out recommendation if the number of days the order is going to arrive early is less than the acceptable early days delivery. This allows you to reduce the amount of rescheduling activity within a material plan. You can make a business decision that it is acceptable to temporarily carry more inventory to reduce the nervousness of the material plan.

For example, suppose you define 2 days as acceptable for early delivery, and the current date of an order is Day 2. If the planning process determines that the actual due date should be Day 3 or Day 4, the planning process does not suggest rescheduling of the order. Oracle Master Scheduling/MRP and Supply Chain Planning suggests rescheduling only when the new need date is Day 5 or later.

Attention: Acceptable early days delivery only has an effect on orders that are due to arrive earlier than they are needed. Oracle Master Scheduling/MRP and Supply Chain Planning always generates a reschedule in message if an order is scheduled to arrive later than it is required.

Although the planning process may suggest rescheduling some scheduled receipts and may not suggest rescheduling others because of the acceptable early days limit, it does not violate the order of the current scheduled receipts. In other words, if one scheduled receipt is not rescheduled (because it falls within the acceptable early days delivery) and the planning process wants to suggest rescheduling another scheduled receipt out past the first scheduled receipt, Oracle Master Scheduling/MRP and Supply Chain Planning does not suggest rescheduling either.

For example, if the material plan for an item looks as follows:

Day 2 Day 3 Day 4 Day 5 Day 6 Day 7

Gross Requirements 0 0 0 0 100 100

Scheduled Receipts 0 100 0 100 0 0

Table 1 - 30. Material Plan (Page 1 of 1)

	Day 2	Day 3	Day 4	Day 5	Day 6	Day 7
Gross Requirements	0	0	0	0	100	100
Scheduled Receipts	0	100	0	100	0	0
Table 1 - 30. Material Plan (Page 1 of 1)

Discrete job A is due on Day 3 and discrete job B is due on Day 5.

If you have defined acceptable early days delivery to be zero, Oracle Master Scheduling/MRP and Supply Chain Planning recommends that the discrete job B be rescheduled from Day 5 to Day 7, and that discrete job A be rescheduled from Day 3 to Day 6.

If you have defined acceptable early days delivery to be 2 days, Oracle Master Scheduling/MRP and Supply Chain Planning does not recommend either scheduled receipt to be rescheduled. Rescheduling the discrete job B to Day 7 does not occur because Oracle Master Scheduling/MRP and Supply Chain Planning would only be recommending a reschedule out message of 2 days, which is equal to the acceptable early days delivery. In the previous example, Oracle Master Scheduling/MRP and Supply Chain Planning recommended that the discrete job A be rescheduled to Day 6. In this case, however, Oracle Master Scheduling/MRP and Supply Chain Planning would only recommend rescheduling discrete job A to Day 5 to preserve the original order of the scheduled receipts. However, rescheduling from Day 3 to Day 5 is a reschedule out recommendation of only 2 days, that equals the acceptable early days delivery. Therefore, in this scenario, Oracle Master Scheduling/MRP and Supply Chain Planning would not recommend either job be rescheduled.
