Я делал так:

        var url = Mscrm.CrmUri.create("/_controls/lookup/lookupinfo.aspx");
        var args =
            {
                customViews: [{
                    id: "{A76B2C46-C28E-4E5E-9DDF-951B71202C9D}",
                    recordType: 3,
                    name: "Contact's opportunities",
                    fetchXml: fetchXml,
                    layoutXml: "<grid name=\"\" jump=\"name\" select=\"1\" icon=\"1\" preview=\"0\"><row name=\"opportunity\" id=\"opportunityid\"><cell name=\"name\" width=\"300\" /></row></grid>",
                    Type: 0
                }],
                availableViews: null
            };
        url += "?AllowFilterOff=1&DefaultType=3&DefaultViewId=%7bA76B2C46-C28E-4E5E-9DDF-951B71202C9D%7d&DisableQuickFind=0&DisableViewPicker=0&LookupStyle=single&ShowNewButton=1&ShowPropButton=1&browse=false&objecttypes=3"
        return openStdDlgWithCallback(url, args, 600, 600);
