減去水晶報表公式編輯器中的wo db字段

Question

我有兩個相同類型的業務對象List<DenominationDataEntity>添加到水晶報表中。 1. ReceivedDenomination 2. PaidDenomination。

我必須顯示兩個列表的值，然後我必須減去這兩個列表的字段的值。例如
。 ReceivedDenomination和PaidDenomination都有字段Thousand現在我不得不減去ReceivedDenomination.Thousand和PaidDenomination.Thousand的值。我用下面的代碼創建了公式字段。

Global numberVar TotalThousand :=0; 

(if IsNull({ReceivedDenomination.Thousand}) then 
    TotalThousand 
else 
    TotalThousand := ToNumber({ReceivedDenomination.Thousand}) 
); 

(if IsNull({PaidDenomination.Thousand}) then 
    TotalThousand 
else 
    TotalThousand := TotalThousand + ToNumber({PaidDenomination.Thousand}); 
); 
TotalThousand 

我遇到的問題是TotalThousand字段返回錯誤的答案。即，如果

ReceivedDenomination.Thousand是85和PaidDenomination.Thousand爲2，則我得到2，而不是83

Answer 1

我你嘗試做這樣的嗎？

Global numberVar TotalThousand :=0; 
Global numberVar RcvdThou := 0; 
Global numberVar PdThou := 0; 

(if IsNull({ReceivedDenomination.Thousand}) then 
    TotalThousand 
else 
    RcvdThou := ToNumber({ReceivedDenomination.Thousand}) 
); 

(if IsNull({PaidDenomination.Thousand}) then 
    TotalThousand 
else 
    PdThou := ToNumber({PaidDenomination.Thousand}); 
); 
TotalThousand := RcvdThou + PdThou; 
TotalThousand; 

如果這仍然給您一個問題，請嘗試將公式分成多個公式，並查看每個字段給您的內容。所以你會有TotalThousand，RcvdThou，PdThou和Total formala。 TotalThousand將實例化全球，而RcvdThou和PdThou將顯示2個數字，Total將提供數學。
