DefinitionValue fields are only required in costing-based Profitability Analysis. These are the fields that contain the currency amounts and quantities that you want to analyze in CO-PA. They represent the structure of your costs and revenues.
All the value fields that exist are stored in a field catalog. You can add these fields to your operating concerns by choosing Structures® Operating Concern ® Maintain Operating Concern in Customizing.
The semantic meaning of a value field is determined by the data element to which it is assigned. The data element contains the texts that appear on the screen and in reports for the value field.
There are two types of value fields:
Each quantity field is assigned a field containing a unit of measure. Consequently, each quantity field in a line item can use a different unit.
Value fields can be categorized according to how and when they are defined:
Value fields that are used frequently are predefined in the standard R/3 System. These include fields such as revenue, sales quantity, incoming freight, outgoing freight, and others. You can select those predefined value fields that you wish to transfer into your own operating concern.
In addition to the predefined value fields, you can also define your own value fields. You define these in the field catalog— independent of any client or operating concern — and can later add them to your operating concerns. You create value fields in Customizing under Structures
The definition of a value field consists of its name, texts, a rule defining how it is aggregated over characteristics of time, and whether it is an amount field or a quantity field. There are two texts for each value field —a "description" and a "short text". These texts are displayed on the screen to label the value field.
The aggregation rule determines how the values in a value field are to be handled when data is aggregated over multiple periods in planning and in reports. This does not affect the posting logic. You can choose from three aggregation rules: Addition, Average, and Last value. In most cases, you will want to add the values. Only noncumulative values, such as the number of employees, require the other options.
