| # To use the rate determiner The rate determiner is used to determine whether you want to use a variable currency rate (Rate Determiner = Document Date, Expected Cash Date) for all invoice transactions or a fixed currency rate (Rate Determiner = Fixed or Manually Entered). The currency rate can be determined in different ways to make sure that the method is in line with the way you run your business. For the Document Date rate determiner, the currency rate is retrieved with the invoice date and the business partner exchange rate type, from the Currency Rates (tcmcs0108m000) session. For the Expected Cash Date, ERP LN takes the Terms of Payment days into account to calculate the invoice date to retrieve a rate from the Currency Rates (tcmcs0108m000) session. As a result, the invoice amounts can have different currency rates during the life cycle of the project. If you want to use the same currency rate for a project, you can use the Fixed or Manually Entered rate determiner. For example, if you work with long-term contracts, you want to be sure that the currency in which your project is paid by your American business partner, is virtually inflation-proof. In case of a Fixed rate determiner, you might use currency hedging and buy dollars to counterbalance inflation risks. You invoice for a fixed business partner currency rate, which you enter in the Rate field in the Project - Business Partners (tppdm6501m000) session. If you use the Manually Entered rate determiner, you can also enter the currency rate. This entered currency rate remains fixed for the life cycle of the project, as with Fixed. However, with Manually Entered the currency differences (currency write offs) are used in the interim result. Note that the Rate field can only be entered in these two cases and only in the Business Partner by Project (tppdm6101s000) session or the Business Partner - Contract Sub Amounts (tppdm7141m000) session. As a result, the invoice amounts will have the same currency rate during the project. The Currency Rates (tcmcs0108m000) session is not used. In an independent currency system situation, the following rate determiners also apply: Fixed local: The rate is only fixed for the local currency. Fixed Hard: The rate is fixed for the reporting currencies. Local + Hard: The rate is fixed for all three home currencies. Note The Rate Determiner default is retrieved from the sold-to business partner. Only, if all the invoice lines for the related business partner in Central Invoicing have the status Posted, you can change the rate determiner in the Business Partner by Project (tppdm6101s000) session. Business partner currency. By default, this is the currency of the invoice-to business partner. In Project, the business partner currency is used for all invoice transactions and for the contract amount. In cost plus transactions, the invoice currency can be changed to a different currency than the business partner currency. For these transactions a separate invoice is printed. Exchange-rate type The Exchange Rate Type in the Business Partner by Project (tppdm6101s000) session, is used to calculate the currency rate of the business partner currency and the contract amounts. If the company uses a dependent multicurrency system, the ERT is valid between the business partner currency and the reference currency. In an independent system, the ERT determines the currency rate between the business partner currency and the three home currencies. In Project there are three Exchange Rate Type parameters available: The Exchange Rate Type for Cost in the General Parameters (tppdm0100s000) is used to calculate estimated amounts in the home currencies in Project Estimating; calculate standard cost object amounts in the home currency and calculate amounts that are not directly project related and have no business partner. The Exchange Rate Type for Revenues in the General Parameters (tppdm0100s000) session is used for invoice exceptions. The currency for sales amounts is normally defaulted from the business partner. If you do not use a business partner (for estimating or manually entered revenues in Revenues (tpppc3501m000), there is no Exchange Rate Type. The Exchange Rate Type for Revenues determines the currency rate from the Currency Rates (tcmcs0108m000) session. The Budget Exchange Rate Type entered in the Template - Project Data (tppdm5101m000) session, is used for specific project-budget processes, for example, budget cost analysis.
