Creating Value Fields 

Procedure

You create value fields in Customizing for Controlling under Profitability Analysis ® Structures ® Define Operating Concern ® Maintain Value Fields. If you define additional value fields, they must follow the naming convention VVxx or VVxxx. The following value fields would be conceivable:

·        Total revenue

·        Domestic revenue

·        Foreign revenue

·        Unit charges (fixed network)

·        Data volume

·        Calling minutes

When you create a value field, you must decide whether it is an amount field or a quantity field. Amount fields are always supplied with the net amount of the invoice line (field DFKKOPK – BETRW). Quantity fields are always supplied with the settlement amount of the invoice line (field DFKKOPK – MENGE).
How many value fields you need depends on your characteristics. For example, you could create two value fields domestic revenue and foreign revenue. However, if you use the tariff or the tariff group as the characteristic, it is sufficient to have one value field revenue since domestic and foreign connections differ with reference to this characteristic.
For contribution margin accounting and cost-efficiency analysis, it is advisable to use several amount fields since this enables evaluation of the composition of the total revenues from basic prices, discounts, and flat rates. You need fewer quantity fields than amount fields. Only settlement steps that settle quantities or activities generate invoice lines with which the settlement quantity has a value.
