You can create an ATP rule.
To create an ATP rule:

ATP Rule Information | |
Past Due Supply Days | Enter the number of days after which supply that is not received
cannot be considered in ATP calculations. For example, if you do not want to fulfill orders on supplies that are overdue by 2 days, enter 2 as the parameter for Past Due Supply Days. Note: IBM® suggests
using a value of '730' initially. Evaluate the system's behavior and
adjust this value higher or lower as necessary.
|
Past Due Demand Days | Enter the number of days after which demand for a product item
is not considered in the ATP calculation. For example, if demand for a product item is delayed for longer than the requested ship date, you can limit the amount of time this demand can use up available inventory. Any demand that is past due for the number of days specified in this parameter is not included in ATP calculations for demand. Note: IBM suggests
using a value of '730' initially. Evaluate the system's behavior and
adjust this value higher or lower as necessary.
|
Forward Consumption (Days) | Enter the number of days future supply can be consumed to fulfill
a current demand. Note: IBM suggests
using a value of '730' initially. Evaluate the system's behavior and
adjust this value higher or lower as necessary.
Note: For tag controlled items, if demands are
being matched against future inventory (purchase orders), during scheduling
of a current order, the ForwardConsumptionDays is not considered.
However, during an existing supply and demand reallocation the ForwardConsumptionDays
is considered. This may cause a new order (refer to previous note)
to be backordered because reallocation of other existing demand considers
incoming supply only up to ForwardConsumptionDays. To avoid this,
if possible, set the ForwardConsumptionDays in the ATP rule equal
to the value defined in the "Maximum no. of days order can be shipped/delivered
beyond its requested date" rule.
|
Backward Consumption (Days) | Enter the number of days to go back and check for available
supply for a current demand. Demands are matched against the supply available on the same day. If there is not enough inventory available to fulfill the order that day, you can allow the system to consume inventory that was available several days back. You can determine how far back the system can check for available inventory before looking forward. Note: IBM suggests
using a value of '730' initially. Evaluate the system's behavior and
adjust this value higher or lower as necessary.
|
Processing Time For Future Inventory (Days) | Enter the amount of days it takes for inbound and outbound
processing of a product item. This should also include special services
such as gift wrapping, kit items, and special delivery. For example, if it takes 1 day to receive roses and store them in the warehouse and another 2 days to pick, pack, and ship them, then the processing time is 3 days. This parameter is used by the Schedule time-triggered transaction to determine if an order can be scheduled against expected supply. |
Advance Notification Time (Days) | Enter the number of days in advance that a node needs to be
notified to prepare an order for shipment. Release date is based on Advanced Notification Time. This is calculated as: <release date> = <requested ship date> - <advanced notification time>. An order is picked up for release if any line has a release date less than or equal to today. All other lines in the order with a ship date less than or equal to the lines satisfying the release date are also scheduled to ensure that they are shipped together. This parameter is used by the Release time-triggered transaction to determine when an order should be released to the ship node. Note: IBM recommends
using a value of '0' for this field.
|
Accumulation Time (Days) | Enter the number of days for which a supply can be considered
available for future demand. This parameter determines whether a currently available supply of a product item can be considered for future order fulfillment. This parameter must be set to less than or equal to the Backward Consumption Days. For example, if a purchase order becomes 'onhand' on 11/1 and this parameter is set to 10 days, the inventory from the purchase order is considered available until 11/11. Note: IBM suggests
using a value of '730' initially. Evaluate the system's behavior and
adjust this value higher or lower as necessary.
