Basis Types
(a) Basis
types determine how costs are assigned to the item.
(b) Basis
types are assigned to subelements, which are then assigned to the item.
(c) Each
subelement must have a basis type. Examples: one hour of outside processing per
basis item, two quarts of material per basis lot.
(d) Basis
types are assigned to subelements in three windows and, for the overhead
subelement, a setting established in one window may not always be applicable in
another. (This refers specifically to the overhead subelement, not the material
overhead subelement.)
Basis types in Subelement and Routing Windows
(a) Basis
types assigned to subelements in subelement and routing windows are the
defaults for the purpose of routing.
(b) Basis
types Resource Units and Resource Value, when assigned to an overhead
subelement(Routing only in the table below), are available to flow
through to routing, but are not available in the Item Cost window.
Basis types in the Item Cost window
(a) When
you are defining item costs, for any overhead subelement with a previously assigned
basis of Resource Units or Resource Value, that basis is ignored, and only item
or lot appears in the basis pop-up window.
(b) This
does not change the assigned basis for the purpose of routing.

Item
(a) Used
with material and material overhead subelements to assign a fixed amount per
item, generally for purchased components.
(b) Used
with resource, outside processing and overhead subelements to charge a fixed
amount per item moved through an operation.
Lot
(a) Used
to assign a fixed lot charge to items or operations.
(b) The
cost per item is calculated by dividing the fixed cost by the item's standard
lot size for material and material overhead subelements.
(c) For
routing steps, the cost per item is calculated by dividing the fixed cost by
the standard lot quantity moved through the operation associated with a
resource, outside processing, or overhead subelement.
Resource Value
(a) Used
to apply overhead to an item, based on the resource value earned in the routing
operation.
(b) Used
with the overhead subelement only and usually expressed as a rate. The overhead
calculation is based on resource value:
Resource value
earned in the operation x overhead rate
Resource Units
(a) Used
to allocate overhead to an item, based on the number of resource units earned
in the routing operation.
(b) Used
with the overhead subelement only. The overhead calculation is based on
resource units:
Resource Units
Earned In An Operation X Overhead Rate Or Amount
Note: You
may optionally use resource units and resource value to earn material overhead
when you complete units from a job or repetitive schedule.
Total Value
(a) Used
to assign material overhead to an item, based on the total value of the item.
Used with the material overhead subelement only. Material overhead calculation
is based on total value:
Activity
(b) Used
to directly assign the activity cost to an item. Used with the material
overhead subelement only. The material overhead calculation is based on
activity:
Activity
occurances / # of items X activity rate
