Defining ATP Rules
To define an available to promise rule:
2. Enter a unique name for the rule.
Forward: Uses the available quantity from future periods to cover a period shortage.
Backward: Uses the available quantity from prior periods to cover a period shortage.
4. If you selected Backward consumption, indicate whether ATP information should be calculated by carrying available quantity from one period over to the next (Accumulation).
5. If you choose to accumulate available quantity, enter the number of days to define this window of time in the Accumulation Window field.
When calculating the ATP quantity of an item, Oracle Inventory does not consider any supply source scheduled on or after this date. The infinite supply time fence date marks the end of the ATP horizon, after which Inventory assumes infinite supply is available to cover any scheduled demand.
Cumulative total lead time: Use the cumulative total lead time of the item.
Cumulative mfg lead time: Use the cumulative manufacturing lead time of the item.
Total lead time: Use the preprocessing, manufacturing, and postprocessing lead times of the item.
User-defined time fence: Use a lead time you specified when you defined the item
8. If you choose the User-defined time fence option, enter the number of lead time days in the Days field. This field is not available with other Infinite Supply options.
9. Indicate whether to calculate ATP based on defined demand classes. Demand classes allow you to segregate scheduled demand into user-defined groups.
If you choose to calculate ATP based on defined demand classes the following Supply Source options are not available: on-hand available, interorg transfers, purchase orders, internal and supplier requisitions.
