計算測量

Question

非空函數我寫了一個計算的措施如下

With member [Measures].[Path] as 
Iif (condition, DisplayIteration, null) 


Select [Measures].[Path] , 
[Measures].[Caption], 
[Measures].[Value] on 0 , 
{NonEmpty 
(
Crossjoin (
[Item].[Product], 
Descendants ([Item].[Iteration]) 
) 
, Descendants ([Item].[Iteration]) 
) 
}on 1 from [Item] 

的[措施] [路徑]是報表參數標籤和[措施]。[值]是一個報表參數值。由於過濾器應用於後代（[Item]。[Iteration]），因此仍然可以看到[Measures]。[Path]的空值。是否有任何方法可以解決這個問題？

Answer 1

作爲非空的替代， 。可以試試存在（）與MeasureGroupName參數測量的NullProcessing財產不得設定爲保留

你可以看看下面的線程：

菲利普，

Answer 2

我看到兩個可能性lities接近您的要求：

要麼使用[Measures].[Path]作爲第二個參數，以NonEmpty：

With member [Measures].[Path] as 
Iif (condition, DisplayIteration, null) 

Select [Measures].[Path] , 
[Measures].[Caption], 
[Measures].[Value] on 0 , 
{NonEmpty 
(
Crossjoin (
[Item].[Product], 
Descendants ([Item].[Iteration]) 
) 
, { [Measures].[Path] } 
) 
}on 1 from [Item] 

，或者使用HAVING代替NonEmpty，其可以是更具選擇性的條件：

With member [Measures].[Path] as 
Iif (condition, DisplayIteration, null) 

Select [Measures].[Path] , 
[Measures].[Caption], 
[Measures].[Value] on 0 , 
Crossjoin (
[Item].[Product], 
Descendants ([Item].[Iteration]) 
) 
Having Not [Measures].[Path] Is null 
on 1 from [Item] 

我不確定結果或表現的正確性的影響，你將不得不測試。
