Payment with Data Medium Exchange in Local and Hard Currencies 
As of Version 4.6A, SAP Travel Management enables you to pay travel expenses with data medium exchange in local and hard currencies.
Payment in hard currency is currently only possible for Mexico.
Prerequisites
Prerequisite for this is that you want to reimburse receipts in hard currency and you have set this up in Customizing for Travel Management. To do this, navigate to Customizing for Travel Management under 
Travel Expenses 
Master Data Control Parameters for Travel Expenses Global Settings 
and select the In Hard Currency indicator in the "Settlement of Foreign Currency Receipts" area.
To transfer the trip reimbursement amounts to the employees in local and hard currency, you must also create two sets of bank details for the respective employees in their personnel master record. Enter these specifications in infotype 009 (Bank Details):
Specify the bank details for trip reimbursements in local currency under Main Bank or alternatively in the Bank details for travel expenses.
Enter the bank details for the hard currency in the Bank details for travel expenses in hard currency. Enter the hard currency in the Currency field. If you enter a bank account in these bank details for the employee, this account should be managed in the hard currency, so that the transferred amounts are not translated into country currency by the bank.
