Dynamics CRM Plugin FetchXML貨幣字段求和

FetchXML貨幣字段求和，是對貨幣的base字段求和，所以求和結果需要乘以匯率。

即便求和的字段爲貨幣字段，不是對應的base字段，求和結果仍然是base字段的求和結果。

所以，對於用FetchXML做貨幣字段的求和，建議直接用base字段，結果乘以匯率。以免產生歧義和誤導。

對於貨幣字段的FetchXml的查詢，顯示的結果就是字段的值，並不是base字段的值。

另，查詢和求和FetchXML的寫法也有所不同，求和會有aggregate='true'。

 

Demo FetchXML求和

                                                                <entity name='new_priceevaluationproduct'>
