In this activity, you can define your own
value fields . Frequently used value fields, such as "Revenue" and "Sales quantity", are already predefined in the standard system.
You define these values independent of any operating concern and any client.
Before you create a new value field, you should take a look at the ones that already exist. It may be that you can use a value field you have already define or one defined in the standard system.
Once you are in the "change" mode, you can define a new value field by choosing the "Create" icon:
Enter a 4- or 5-character name that begins with "VV" for your value field. Here you also need to specify whether this field is a quantity field or a field for currency amounts. All the currency fields in any single line item use the same currency. This currency is defined in the attributes of each operating concern. Each quantity field, on the other hand has its own field that defines the unit of measure. Thus you can have quantities in different units in the same line item.
On the next screen, you can enter texts to describe the value field, as well as how the values in this field are to be aggregated over characteristics of time . In most cases, you will use the aggregation rule "SUM" (summation) to add up the values over periods. The aggregation rules "Last value" (LAS) and "Average" (AVG) are only of significance if the value field is to contain a statistical non-cumulative value.
