Supply Usage Tolerance

This field applies to APS.

This field allows you to configure the APS system to be able to use a supply (such as a purchase order line item) to satisfy a demand that is due earlier than the supply is due. This field appears as an item-specific value on the Items or Multi-Site Items form and as a global value on the Planning Parameters form. A value of 0 entered on the Items form bypasses the item-level tolerance; the system instead uses the global tolerance value.

You can define the tolerance time window in terms of hours or days, depending on whether you enter a positive or negative number in Supply Usage Tolerance:

• Positive number: the system searches for supplies starting from the demand's due date/time + the tolerance number of hours. For example, if the demand's due date is 3/5/2004 at 9:00, a value of 4 means the demand can use any supplies that are available between the current date/time and 3/5/2004 at 13:00.
• Negative number: the system searches for supplies starting from the demand's due date at 00:00 (midnight) + (24 hours * the positive tolerance value). For example, if the demand's due date is 3/5/2004 at 15:00, a value of -4 means the demand can use any supplies that are available up to 3/9/2004 at 00:00. In the same example, a value of -1 means the demand can use any supplies available up to 3/5/2004 at 24:00 (the same day).

The system uses this parameter only if the Use Supply Usage Tolerance option is selected on the Planning Parameters form. See Using Supply Usage Tolerance for more information.
