Dynamics crm CRM 2011从ActivityPartySet获取必需和可选联系人姓名

我正在尝试在SSRS for CRM 2011中创建报告，并尝试从任命集获取信息。我能够获得除必要和可选与会者之外的所有信息。我敢肯定，这些任命为与会者设置了指向ActivityPartySet的链接。但我不确定。您将如何获得所需的与会者和可选的与会者。这就是我目前所拥有的

我不完全清楚您的要求，但以下代码片段将返回可选或必需与会者的完整详细信息，但前提是他们是系统用户记录。如果参与方包含其他记录类型，则不会返回任何结果

<entity name='appointment'>
    <attribute name='subject'/>
    <attribute name='actualend'/>
    <attribute name='actualstart'/>
    <filter type='and'>
        <condition attribute='activityid' operator='eq' value='MyActivityGuid'/>
    </filter>
    <link-entity name='activityparty' from='activityid' to='activityid'>
        <attribute name='partyidname'/>
        <attribute name='participationtypemask'/>
        <attribute name='activityid'/>
        <attribute name='activitypartyid'/>
        <attribute name='addressused'/>         
        <attribute name='participationtypemaskname'/>
        <attribute name='partyid'/>
        <attribute name='partyiddsc'/>
        <attribute name='partyobjecttypecode'/>
        <attribute name='resourcespecid'/>
        <attribute name='resourcespeciddsc'/>
        <attribute name='resourcespecidname'/>
        <attribute name='scheduledend'/>
        <attribute name='scheduledstart'/>
        <filter type='and'/>
        <filter type='or'>
            <condition attribute='participationtypemaskname' operator='eq' value='Optional attendee'/>
            <condition attribute='participationtypemaskname' operator='eq' value='Required attendee'/>
        </filter>
        <link-entity name='systemuser' from='systemuserid' to='partyid'>
            <attribute name='fullname'/>
        </link-entity>
    </link-entity>
</entity>

这有用吗
