Valuation Principles and Valuation Classes
When you implement the Transaction Manager, you define the valuation principles and valuation classes according to which you want to perform valuation in the operative valuation area. You make these definitions in Customizing under General Settings. Choose Accounting -> Operative Valuation Area -> Define One-Step Valuation Principles, Define Two-Step Valuation Principles, or Define Valuation Classes.
The valuation principles define the rules according to which you perform valuation. A valuation principle comprises the valuation method and the rules which define how to write up and write down the foreign currency and the security.
The valuation methods are as follows:
When you have chosen the valuation method, you define the rules you want to use to determine the new book value when comparing the last book value, the key date value and the acquisition value. You then write it up/down accordingly.
When you use the one-step method, you define how to perform write-ups/write-downs to the total amount in local currency.
When you use the two-step methods, there is a difference between the write-up/write-down amount for the security price and for the exchange rate.
The graphic below provides an overview of the valuation principle and shows you which write-up/write-down rules you can define.
