例如，我开发了一个 CDS view，并主动生成了一个 Fiori Elements 利用，外面显示的金额单位是欧元：
我冀望利用 CDS view 的货币转换性能，currency conversion，将这些金额的单位转换成美元。
能够应用这个文档里提到的转换函数。
应用如下高亮代码：
@AbapCatalog.sqlViewName: 'ZCTRAVELJERRY'@AbapCatalog.compiler.compareFilter: true@AbapCatalog.preserveKey: true@AccessControl.authorizationCheck: #CHECK@EndUserText.label: 'Consumption view from /DMO/I_TRAVEL_U'@Metadata.allowExtensions: true@Search.searchable: truedefine view Z_C_TRAVEL_DATA_JERRY as select from /DMO/I_Travel_U association [1..1] to /DMO/I_Agency as _Agency on $projection.AgencyID = _Agency.AgencyIDassociation [1..1] to /DMO/I_Customer as _Customer on $projection.CustomerID = _Customer.CustomerID{ key TravelID, @ObjectModel.text.association: '_Agency' AgencyID, CustomerID, concat_with_space(_Customer.Title, _Customer.LastName, 1) as Addressee, BeginDate, EndDate, BookingFee, TotalPrice, CurrencyCode, currency_conversion( amount => TotalPrice, source_currency => CurrencyCode, round => 'X', target_currency => cast('USD' as abap.cuky( 5 )), exchange_rate_date => cast('20200429' as abap.dats), error_handling => 'SET_TO_NULL' ) as PriceInUSD, @Search.defaultSearchElement: true @Search.fuzzinessThreshold: 0.90 Memo, Status, LastChangedAt, /* Associations */ _Agency, _Booking, _Currency, _Customer}最初的成果：
转换成果如下：蓝色是原始的欧元单位，红色的是通过 currency_conversion 转换之后的新值：
