At the conclusion of a project, accumulated costs are transferred from the project to the fixed asset master record. This process is known as cost settlement. The costs on a single WBS element may be transferred to one or multiple fixed assets. This allocation can be by fixed amount or percentage. These percentages can vary by time. Different expenditure types can be settled to different receivers. For example, some cost types can always be treated as operational expenditure. This specification of what expenditure is settled to which receivers, in what proportion, is defined by a settlement rule.
