【问题描述】：

我正在尝试使用 Microsoft Dynamics 365 Web API 从约会实体中删除字段 regardingobjectid 的值。不能，但它显示以下错误：

  "error": 
    "code": "",
    "message": "The property 'regardingobjectid' does not exist on type 'Microsoft.Dynamics.CRM.appointment'. Make sure to only use property names that are defined by the type."

  ]

【参考方案1】：

几件事：

1.要使用web api更新/覆盖查找字段值，我们必须使用单值导航属性[e-mail]

var entity = ;
entity["[e-mail]"] = "/accounts(1F496057-8DE7-E811-A97A-000D3A1A9EFB)";

var req = new XMLHttpRequest();
req.open("PATCH", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/appointments(6D78AD2C-5A16-E811-A955-000D3A1A9407)", true);
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.onreadystatechange = function() 
    if (this.readyState === 4) 
        req.onreadystatechange = null;
        if (this.status === 204) 
            //Success - No Return Data - Do Something
         else 
            Xrm.Utility.alertDialog(this.statusText);
        
    
;
req.send(JSON.stringify(entity));

2.如上所述PATCH用于更新所有字段类型的值，除了删除查找值（在查找中更新null） - 我们必须使用DELETE

经过一些研究请求后 DELETE: XXXXXXX.crm.dynamics.com/api/data/v8.2/… 对我来说非常适合删除有关objectid
