Currency Rates
This function is used to define currency rates and to inquire the history of rates in the form of a graph or table. A currency rate is defined:
- for a given currency,
- for a given rate type,
- at a given date.
A direct rate can thus be associated with each given destination currency (the inverse rate being displayed).
Prerequisites
Refer to documentation Implementation
Screen management
In the screen, the 3 start data (source currency, rate type and rate date) are entered.
All currencies for which a rate has been defined at this date or at a later date are then displayed. In addition, these rates can be modified (the application date being displayed).
It is possible to:
- modify a rate for an already entered currency (the rate date corresponding to the modified rate remains unchanged)
- enter a new line in the table, included lines with an existing currency, in order to enter a new rate at a new date.

Currency Initialization
This is used to fill out the table with one line per currency that can potentially have a different rate than the header currency. The lines correspond to the last known rate at the date provided in the header.
If no rate is known at this date for a given currency, a unit rate is suggested in the table.

This tab displays in a "table" and "graph" the selected currency rates. 
This button is used to switch from graph mode to table mode.
In graph mode, dates are displayed in the abscissa and the currency rates are in the ordinate.
The wheel makes it possible for the user to choose the curve type.
Besides, the user can choose whether to display all curves or to hide some (using the expandable menu bar in the top-right corner of the table).
