Dynamics CRM 2011/2013はJavascriptを通じてlookupフィールドに値を割り当てます.

<span style="font-size:18px;">var value = new Array();
value[0] = new Object();
value[0].id = idValue;
value[0].name = textValue;
value[0].entityType = typeValue;

Xrm.Page.getAttribute(“fieldName”).setValue(value);</span>

<span style="font-size:18px;">Xrm.Page.getAttribute(“fieldName”).setValue( [{id: idValue, name: textValue, entityType: typeValue}]);</span>
