计算父代和子代之间的相对兑换率，返回一个乘数值。
返回值
此函数返回要在 HS.EXP 函数中（通常在转换部分）使用的值。
语法
Rate (ExchangeRate, TriangulationCurrency)
表 12-13 Rate 函数的语法
| 参数 | 有效值 |
|---|---|
|
ExchangeRate |
指定为帐户字符串的一个 "CurrencyRate" 类型的主帐户，不引用自定义维或公司内维，例如 "A#EOP_RATE" |
|
TriangulationCurrency |
有效的货币标签（字符串形式）或双引号 (" ")。在指定货币时，不必引用任何自定义维。 |
详细说明
此函数计算父代和子代之间的相对兑换率，返回一个乘数值。该值是基于 TriangulationCurrency 参数计算的。
如果 TriangulationCurrency 参数是有效的货币标签，则交叉汇率将基于此货币。
如果 TriangulationCurrency 参数为空白 (" ")，则该函数将先搜索有效的直接汇率；如果未找到直接汇率，则基于应用程序货币使用三角转换。
如果未找到任何汇率值，函数将返回 1。
以下各表显示了搜索数据的方法以及搜索的顺序。顺序用括号中的数字表示，例如 (1)。在每种情况下，搜索都先在子实体中进行；如果未找到数据，再从 "[None]" 实体中搜索。
在下表中，父代或子代的货币都与中间转换货币相同（如果中间转换货币为空白，则与应用程序货币相同）。

示例
应用程序货币为欧元，您需要使用在 [None] 实体中针对 C2#EURO 输入的以下汇率，将法国子实体换算为美国父实体：
表 12-17 Rate 函数的示例
| Rate | 开盘汇率 | 收盘汇率 |
|---|---|---|
|
C1#FFR |
0.16000 |
0.16500 |
|
C1#USD |
1.15862 |
1.15785 |
以下函数将期初余额帐户乘以相对收盘汇率与开盘汇率之间的差。当本地货币与应用程序货币之间的换算不一致时，此函数可用于计算动态分析。
HS.EXP "A#FXO = A#OPEN * (" & RATE("A#EOP_RATE"," ") & "-" & RATE("A#OPE_RATE"," ") &")"
对于前一个示例，如果子代的 OPEN 帐户中的值为 FFR 10,000,000，则美国父代 FXO 帐户中的值将为 USD 44,102（10,000,000 * (0.165 /1.15785 - 0.16 /1.15862)）。
