Dependency Planning

Use

Dependency planning enables you to plan both activity-independent and activity-dependent primary costs based either on quantity or value, by using proportional dependencies between the object that causes costs and the required components. The system can calculate primary costs for a statistical key figure (activity-independent and dependent) and an activity type (activity-dependent only).

In the case of value-based or cost-based dependency planning, you plan activity-dependent or activity-independent primary costs per unit of a statistical key figure or activity type. Dependency planning that is value-based is typically used in administration. This is often time-consuming for determining proportional contexts. In this area, it is more usual to combine the different parts causing costs under a general term (office supplies for example) and to plan them per unit causing costs (employee for example).

In the case of quantity-based dependency planning, you plan the consumption of a resource per unit of a statistical key figure or activity type, for example Consumption of screws per car, or Consumption of lubricant per production hour. Total plan costs are equal to the consumption per activity unit or unit of a statistical key figure multiplied by the quantity of the object causing the cost (number of cars for example) and the valuation using the resource price. Quantity-based dependency planning is most commonly used in production, where simple proportional dependencies usually exist between finished products and the additional substances required.

You want to plan costs for manufacturing a car body. In addition to the many parts that go to form the body, you also require lubricant, screws and rivets, all three of which are defined as resources. In dependency planning, the system calculates the costs for the car bodies from the planned quantities of the individual car body components (metal parts, screws, rivets), the corresponding prices, and the quantity required in each case per car body (= dependency quantity).

You can determine the different types of planning such as cost or quantity-based planning, and activity-dependent or independent planning using the dependency type It specifies what the dependency price or dependency quantity relates to.

It can be one of the following values:

• 1

The dependency price or dependency quantity relates to the planned quantity of a statistical key figure that you planned on either an activity-dependent or activity-independent basis.

During activity-independent dependency planning, the system calculates planned costs using the (activity-independent) planned quantity of the statistical key figure. If no activity-dependent statistical key figure is planned, the system sets the statistical key figure value in planning to zero.

Under activity-independent dependency planning, the SAP System calculates planned costs using the activity-independent planned statistical key figure quantity.

The system updates the costs entirely as fixed costs.

• 2

The dependency price or dependency quantity relates to the planned quantity of a statistical key figure that you planned on an activity-independent basis.

Even if you plan activity-dependent costs using dependency type 2, the system always uses the activity-independent planned quantity of the statistical key figure to calculate planned costs.

Dependency planning using dependency type 2 is the equivalent of activity-independent dependency planning using dependency type 1.

The system updates the costs entirely as fixed costs.

• 3

The dependency price or dependency quantity is based on the planned quantity of an activity type. Dependency type 3 can be used only for objects that are to be planned on an activity-dependent basis.

The system updates the costs entirely as variable costs.

The dependency type is directly correlated to the dependency source type. It determines whether the system calculates planned costs and planned consumption using (a) activity-independent/activity-dependent planned quantities of statistical key figures or (b) planned quantities of activity types. The system enters the planned quantity for the dependency source type in the dependency source quantity.

• The system calculates planned costs per period.
• If, per period, you defined different dependency prices, dependency quantities, or resource prices, note that these values are not displayed in the planning overview. The value displayed here is an average value. The values per period can only be viewed on the period screen for planning.
• If you change the prices or quantities, the system revalues planning.

Additional, fixed costs that are not dependency-based can only be planned under the same cost element if you define additional resources, for example Additional fixed costs. You must enter a 1 for the resource price

Prerequisites

Before you carry out dependency planning, you should have carried out the following functions:

• For cost-based dependency planning:
• Statistical key figure planning or key figure transfer from the LIS (Logistics Information System) or key figure calculation using formula planning.
• Activity type planning or activity transfer from PP, or indirect activity allocation
• For quantity-based dependency planning:
• Statistical key figure planning or key figure transfer from the LIS (Logistics Information System) or key figure calculation using formula planning.
• Activity type planning or activity transfer from PP, or indirect activity allocation
• Resource definition, price maintenance, planning of resource consumption

You can also carry out dependency planning using data from non-SAP systems.

Features

Dependency planning involves the following:

Manual planning

SAP provides you with the standard planner profile SAPR&R. This planner profile contains standard planning layouts for value-based and quantity-based dependency planning for cost centers.

For more information on planner profiles and planning layouts, see Planner Profiles and Standard Planning Layouts.

If you carry out dependency planning and then call up cost planning with a planning layout that does not contain dependency price and dependency quantity, you cannot enter planned costs.

Revaluation

If you change the quantity of a statistical key figure or an activity quantity, the SAP System automatically revaluates your planning.

Note however, that if you carry out dependency planning with values (statistical key figures, activity types) that you did not plan manually, the SAP System does not automatically revalue planning. In this case, you need to revaluate costs already planned. Only then can you ensure that your planning is up-to-date.
