Enable Conversion Using A Euro Table - IBM Cognos User Manual

This excerpt shows rates for the final quarter of 2006, including three mandatory
columns for the Currency Record dialog box (Date, Country code, and Rate), and
the optional column Label.
To start, conversion rates have a default value of 1.0000, but you can change the
value for any period that is marked with the pencil icon . Note that all rates
represent the amount by which you multiply a unit of the given currency to
convert it to a unit of the base currency. For this example, in December 2006, 1 US
dollar (base currency) cost 1.10 Canadian dollars, 0.60 British pounds, and 112.90
Japanese yen.

Enable Conversion Using a Euro Table

If you have legacy (turn-of-the-century) data and select the Use Euro triangulation
option, you can convert values to or from the currencies of European Monetary
Union (EMU) countries or regions, using the method stipulated for the transition
period.
For those few years when EMU-member countries or regions carried two legal
tenders, special rules apply. Rates had to be expressed in terms of the euro, and
values had to be converted from the original currency to the euro, and then from
the euro to the target currency, with rounding to the specified precision at each
step.
Additional information to be specified in the Currency Record dialog box includes
Entry date in the EMU (YYYYMMDD) and the fixed rates to use when converting
data to or from the national currencies of the EMU countries or regions. As with
the base Currency Table, rates can be added to the euro Currency Table for the
relevant time periods, either manually or by means of one or more external data
sources.
An Entry date in the EMU (YYYYMMDD) is automatically specified for the euro,
which is the default currency in the euro Currency Table. Conversion rates created
for the <Base default> currency before that date are set to zero. This means they
appear as NA in Cognos Transformer, as zero in Model Definition Language
(MDL), and as missing or na in the reporting components.
If you use euro triangulation, the date column in your data source must be sorted
in ascending order and all date levels must be set to Unique on their property
sheets. Remember that you cannot change externally supplied rates after they have
been imported into your Currency Table. Fixed rates are those not marked with
the pencil icon .
The Check Model tools issues a warning if your model contains a Currency Table
but none of the measures have currency conversion enabled. You can ignore this
message; however, currency conversion will not be available in any OLAP
reporting components.
