Transaction Currency Changeover (TR-TM-MM/FX/DE) 
Purpose
You can convert the transaction currency of financial transactions with due dates which fall within the dual currency phase (from 01/01/1999 to 01/01/2002) to the common euro currency. However, this is not mandatory.
By contrast, if the transaction due date falls after the dual currency phase, the changeover of the transaction currency is compulsory, since the participating currencies will no longer be valid after this period.
You change over the currency for individual transactions upon agreement with the business partners involved.
You can carry out the transaction currency changeover before or after the local currency changeover.
The report program for the transaction currency changeover also allows you to value the transactions at a fixed euro rate without actually carrying out the changeover. This is necessary when the transaction currency changeover is only carried out after the key date at which gains and losses resulting from the fixed euro translation have to be realized. For more information, refer to the section headed Valuation Without Conversion under
Money MarketThe following examples look at four different scenarios for the transaction currency changeover in the money market area:

1:
Transaction currency changeover after the local currency changeoverLC = TC = DEM
TC changeover as at 01/01/2001
LC changeover as at 01/01/1999

LC = Local currency
TC = Transaction currency
FC = Foreign currency (participating currency)
The system does not create any additional valuation flows during the transaction currency changeover.
The euro valuation flows are taken into account when the realized gains and losses are calculated.

2:
LC ¹ TC
LC = DEM / TC = FRF
LC changeover as at 01/01/1999
TC changeover as at 01/01/2001

LC = Local currency
TC = Transaction currency
FC = Foreign currency (participating currency)
Posting System for Example 2
T-account example: Money Market
Transaction : 1000 FRF
LC : DEM (already valued at fixed rate)
TC changeover : FRF ® EUR

3:
LC = TC = DEM
LC changeover as at 01/01/2001

LC = Local currency
TC = Transaction currency
FC = Foreign currency (participating currency)
Gains and losses resulting from the transaction currency changeover are disclosed separately, regardless of the valuation principle for the corresponding transaction type. Any valuations after this point in time do not generate additional gains and losses.
The gain/loss that has already been disclosed is taken into account when the realized gains/losses are calculated.

4:
(LC ¹ TC)
LC = DEM / TC = FRF
LC changeover as at 01/01/2001
TC changeover as at 01/01/2000

LC = Local currency
TC = Transaction currency
FC = Foreign currency (participating currency)
