Dynamics 365-插件不會更新值

Question

從昨天開始，我一直在追逐這一切，沒有任何意義。 我經歷了代碼的各種排列-將Decimal類型函數更改為String並返回String而不是十進制，使用了十進制數字，在if語句中硬編碼值（不使用變量），和使用變量本身，但似乎沒有任何效果。 如果我僅在try塊的開頭設置字段值，並且不執行任何類型的邏輯，則說明字段已過時。 當我通過插件注冊工具中的Plugin Profiles / Debug逐步執行代碼時，我看到設置值的代碼行被命中，沒有拋出異常，但是再次，值沒有被更新。 我什至試圖添加service.Update（entity）; 但這也不起作用（當我在沒有任何邏輯的情況下設置字段的值時，就不需要service.Update調用來保存值）。

我試圖在CRM中寫入的字段是2精度的十進制類型。 當然，C＃中的小數類型精度為8或10，因此我什至嘗試修剪小數，將小數轉換為字符串，等等，但是沒有用。

有什么想法可以幫助我弄清楚這里發生了什么嗎？

我在這里發布了最簡單的代碼版本-在我將Decimal類型函數更改為string等之前。

現在，在這里您可以看到我當前的代碼，在這里我正在做很多瘋狂的事情-首先，使用String類型的函數取回十進制值。 其次，調用一個函數以實際設置值，只是為了證明現有函數沒有什么問題（並允許更輕松地格式化該行）。 無論我做什么，我都無法使這當之無愧的工作！

Answer 1

我的回答基於對您的代碼的以下假設：

1. 用例是，當使用msdyn_agreement字段中的值創建msdyn_workorder記錄時，應將工作訂單上的client_ntepercent值設置為協議上的client_ntepercent值。
2. 該插件已在msdyn_workorder實體上的“創建”消息的預操作階段中注冊。

建議的修復程序需要進行以下更改：

1. 該代碼需要從目標實體獲取msdyn_agreement值，而不是執行檢索查詢，因為該工單尚未保存到數據庫中。

出現問題的原因可能是您正在查詢工作訂單記錄以從操作前插件中獲取協議值。 工作訂單尚未保存在數據庫中。
