Defining Activities and Activity Costs
Define activities, activity rate information, and activity and cost type associations. Use activities to assign indirect costs to items based upon the effort expended to obtain or produce the item, rather than as a percentage of a direct cost or an amount per item.
Activities are processes or procedures that consume costs and time. In addition to cost elements and sub-elements, costs may be associated with an activity. Activities may be directly related to building items, such as runtime or setup time; or they may be indirect, such as purchase order generation, payroll, and engineering activities. The goal of activity based cost accounting is to accurately identify your product costs, especially overhead costs.
Prerequisites
To define, update, or delete cost information, the Activities: Maintain security function must be included as part of the responsibility. See: Cost Management Security Functions.
To define activities and activity costs:
1. Navigate to the Activities window.
Note: If disabled, the name is only available to the organization that creates it. If enabled, only the activity name is shared, not the activity.
Basis is the method used to determine how to charge a transaction or apply product costs. The value you enter here is defaulted when you define item costs. The activity default basis will override the sub-element default basis as long as the basis is valid for the cost element. See: Defining Item Costs.
Activity: Used to apply activity costs to items. The activity basis type can only be used with the material overhead sub-element. The item cost is calculated by multiplying the activity cost by the ratio of the number of times the activity occurs, divided into the cumulative quantity of the item associated with those occurrences.
Item: Used to earn and apply costs for all sub-elements. For material and material overhead sub-elements, you charge a fixed amount per item. For resource, outside processing, and overhead sub-elements, you charge a fixed amount per item moved in an operation.
Lot: Used to earn and apply costs for all sub-elements. The item cost is calculated the same as an Item basis cost, except the unit cost is divided by the cost type lot size to derive the cost per item.
5. Optionally, select a date to inactivate the activity.
An inactive activity cannot be assigned as a default activity when defining material sub-elements, resources, or overhead. An inactive activity also cannot be associated with any resource when defining a routing, with a material overhead sub-element when defining material overhead defaults, or with any sub-element when defining item costs, even if the activity is the default activity for the sub-element.
An inactive activity, however, can still be used when defining item costs. (This applies for a new item if the inactive activity was previously specified for a material sub-element as material overhead defaults were defined.) Also, previously defined sub-elements referencing an inactive activity can still be used.
7. Choose the Activity Costs button and select a cost type to associate with your activity. Each activity can be associated with any number of cost types and each cost type and activity combination can have a different cost.
The system calculates the cost per occurrence by dividing the total cost by the total occurrences. This cost is used when you use a basis type activity for the material overhead sub-element.
