解決Tableau中IF結果的聚合和非聚合混合錯誤

Question

我正在嘗試在Tableau中執行以下操作。

如果選擇的關鍵人物是銷售或體積（非集合字段），然後調用計算1其他計算2.

IF ATTR([Choose Key Figure])= "Sales" 
THEN [Periodic Calculation] 
ELSEIF ATTR([Choose Key Figure])= "Volume" 
THEN [Periodic Calculation] 
ELSEIF ATTR([Choose Key Figure])="profit" 
THEN [Periodic Calculation 2] 
ELSEIF ATTR([Choose Key Figure])="price per unit" 
THEN [Periodic Calculation 2] 
END 

但我得到以下錯誤： 「不能混用骨料和非集合比較或結果'IF'表達式。「

任何人都可以如何解決這個錯誤幫助嗎？

謝謝。

Answer 1

如果[選擇鍵圖]是一個參數，[週期性計算]和[週期計算2]是行級（非集合）的計算，那麼你可以：

1. 刪除所有的來電ATTR（）中的計算字段 或
2. 除去所有到ATTR（呼叫）並調用聚合函數如SUM（）上的每個參考到[週期計算]或[週期性計算2] 或
3. 保對ATTR（）的調用並在每個引用上調用諸如SUM（）的聚合函數到[定期計算]或[定期計算2]

1和2之間的區別在於是否爲計算內的計算字段指定聚合函數，或者是在使用該計算字段的Tableau工作簿貨架中指定聚合函數。

在這種情況下沒有真正的理由選擇第三種方法，因爲參數一次只能有一個值，所以ATTR（）調用沒有用。
