ATP by Period

ATP by period provides ATP detail for your item over the entire ATP horizon. ATP period start dates begin with the current system date, and change with each supply event that falls on a proceeding date. The supply quantity for the first period includes quantity on hand and open supply orders due on or before the current system date. The demand quantity for the first period includes all requirements with a required date on or before the ATP period end date.

ATP periods always run from one supply event date to the next. For example, if your item is replenished with work in process jobs, and you have jobs scheduled for completion on a weekly basis, ATP periods begins on the job's scheduled completion date and end the day before the next job's scheduled completion date.

The last ATP period displayed in the ATP by Period window has a period start date based on the infinite supply date. Oracle Inventory assumes that any demand beyond the infinite supply date can be met. As a default, Inventory provides an ATP quantity of 10,000,000,000 for the infinite supply date. If ATP results show a quantity of 10,000,000,000, ATP says in effect that you do not have sufficient available to promise until the infinite supply date (in other words, you do not have sufficient ATP on the date you requested, nor at any time beyond that date through the ATP horizon). The infinite supply date is determined by the infinite supply option of the ATP rule. You may specify an number of manufacturing days as the infinite supply fence, or you can use one of the item lead time options. If you choose user-defined time fence and leave Infinite Supply days null, Inventory does not generate an infinite ATP quantity.
