Tiered Service Option Group

A tier is a single row in a tiered service option group. You can use a tiered service option group to produce a variable cost value based on a lookup value. The lookup value from the referencing service option group is matched with the tier values in the tiered service option group.

An association into a tiered service option group starts at the first row and works its way down, with the first tier having the lowest tier values. When an applicable tier is identified and the Quantity Specification is set to System Specified, the lookup value is multiplied by the rates provided in other service option elements in the tier row to determine the amount invoiced. If the Quantity Specification is not set to System Specified, other rates apply.

When a service option element is associated with a tiered service option group, the tier type value determines how the tiered service option group is used. The following tier types are available, depending on the referencing service option element:

Lookup

Use the first tier that matches the value being passed to the tiered service option group.

Lookup Multiple

Use each tier that matches the value being passed to the tiered service option group.

Variable Lookup

Use each tier up to and including the tier that exactly matches the value being passed to the tiered service option group.

Fixed

Use the first tier that matches the value being passed to the tiered service option group. Once in that tier the tier is fixed and cannot change.

Fixed Incremental

Use the first tier that matches the value being passed to the tiered service option group. Increment to the next tier only if the value passed in exceeds the previously used tier. That is, a certain tier level is used; a lower tier level can never be used.

Variable Fixed

This is a merger between variable lookup and fixed tier types. Use each tier up to and including the tier that exactly matches the value being passed to the tiered service option group. Once in the tier that exactly matches, that tier is fixed and cannot change.

Variable Fixed Incremental

This is a merger between variable lookup and fixed incremental. Use each tier up to and including the tier that exactly matches the value being passed to the tiered service option group. Increment to the next tier only if the value passed in exceeds the previously used tier.
