Dynamics 365-插件不会更新值

时间:2018-09-11 18:09:16

标签: c# dynamics-crm microsoft-dynamics dynamics-365

从昨天开始,我一直在追逐这件事,没有任何意义。我经历了代码的各种排列-将Decimal类型函数更改为String并返回String而不是十进制,使用了十进制数字,在if语句中硬编码值(不使用变量),和使用变量本身,但似乎没有任何效果。如果我仅在try块的开头设置字段值,并且不执行任何类型的逻辑,则说明字段已过时。当我通过插件注册工具中的Plugin Profiles / Debug逐步执行代码时,我看到设置值的代码行被命中,没有抛出异常,但是再次,值没有被更新。我什至试图添加service.Update(entity);但这也不起作用(当我在没有任何逻辑的情况下设置字段的值时,就不需要service.Update调用来保存值)。

我要在CRM中写入的字段是2精度的十进制类型。当然,C#中的十进制类型具有8或10的精度,因此我什至尝试修剪小数,将小数转换为字符串等,但无济于事。

有什么想法可以帮助我弄清楚这里发生了什么吗?

我在此处发布了代码的最简单版本-在我将Decimal类型函数更改为string等之前,就已发布

现在,在这里您可以看到我当前的代码,在这里我正在做很多疯狂的事情-首先,使用String类型的函数取回十进制值。其次,调用一个函数以实际设置值,只是为了证明现有函数没有什么问题(并允许更轻松地格式化该行)。不管我做什么,我都无法使这当之无愧的工作!

答案 0 :(得分:0)

我的回复基于以下有关您的代码的假设:

  1. 用例是,当使用msdyn_agreement字段中的值创建msdyn_workorder记录时,应将工作订单上的client_ntepercent值设置为协议上的client_ntepercent值。
  2. 该插件在msdyn_workorder实体上的“创建”消息的预操作阶段中注册。

建议的修复程序需要进行以下更改:

  1. 由于工作订单尚未保存到数据库中,因此代码需要从目标实体获取msdyn_agreement值,而不是执行检索查询。

问题的原因可能是您正在查询工作订单记录以从操作前插件获取协议值。工作订单尚未保存在数据库中。
