Definition

Costing rules specify which procedures are used to cost the base values and costing components of bank transactions.

Costing rules have a fixed part (fixed procedures) and a flexible part (flexible procedures). The fixed part contains pre-defined costing procedures, which you select for costing value components. The flexible part is also used to cost value components, and can be freely defined by the user.

Use

Fixed procedures are costing procedures used for calculating income and cost components such as interest contribution or currency translation contribution, and for calculating the base values used such as average volumes or opportunity interest rates.

When template allocation of process costs is used, the template (controlling area and template name ) is another component of the fixed procedures.

You enter fixed costing procedures in Customizing under (  Profitability Analysis Single Transaction Costing Costing Costing Rule Create Fixed Procedures ).

Flexible procedures allow you to use SAP Banking for calculation needs specific to your bank. Using the flexible procedures you can calculate costing components in the form of absolute amounts, percentage markups or markdowns on base values, or ratios per unit. Flexible procedures are also configured in  Customizing ( Profitability Analysis Single Transaction Costing Costing Costing Rule Flexible Procedures ).

Processing rules, which are used to calculate costing components, are maintained using table entries.
