从Dynamics 365 RetrieveAttributeChangeHistory实体尝试audit。我需要一些帮助为该实体上的OData函数形成正确的语法。由于该函数未绑定，我遇到了一些麻烦，并遇到了以下错误。解决此问题后，就可以在Java程序中实现此调用了。

我需要为OData函数提供正确的参数。有一个Compose Query functions example使用LastXHours Function来展示如何将PropertyName和PropertyValue传递到URL的函数中。
GET [Organization URI]/api/data/v9.0/accounts?$select=name,accountnumber&$filter=Microsoft.Dynamics.CRM.LastXHours(PropertyName=@p1,PropertyValue=@p2)&@p1='modifiedon'&@p2=12
RetrieveAttributeChangeHistory需要以下参数才能正确调用它。

感谢Greg！
只需为正在寻找RetrieveAttributeChangeHistory函数的GET请求示例的用户添加内容：
GET [Organization URI]/api/data/v9.0/RetrieveAttributeChangeHistory(Target=@p1,AttributeLogicalName=@p2)?@p1={'@odata.id':'accounts(E7918C3A-B869-E811-8141-480FC8F421A1)'}&@p2='name'
