You need to edit this file:
c:\Program Files\Business Objects\BusinessObjects Enterprise 11.5\Web Content\Enterprise115\InfoView\Report\report_scheduleBody.aspx
and comment out this:
<!--
<tr id="dBLogonLinksPanel" runat="server">
<td width="1"><asp:linkbutton id="dBLogonImgLink" CssClass="appTreeCtrl" Runat="server" CausesValidation="True">
<asp:Image CssClass="appTreeCtrl" id="dBLogonImg" ImageUrl="../images/minus.gif" border="0" runat="server" ImageAlign="middle" AlternateText=""></asp:Image>
</asp:linkbutton></td>
<td class="schedule" width='99%'><asp:linkbutton id="dBLogonLabelLink" runat="server" CssClass="appTreeCtrl" CausesValidation="True"
Font-Bold="True"></asp:linkbutton></td>
</tr>
<tr id="dBLogonPanel" runat="server">
<td> </td>
<td class="schedule">
<!--#include virtual="report_scheduleBody_include_db.aspx"--></td>
</tr>
-->
I have also commented out the Filters, Printers, Server Groups, and Events panels so that our users only see the options that they really need to use. These are all on the same page, just note that there are two <tr>s for each option, and you need to comment out both of them. The first one will start <tr id="XXXXXLinksPanel" and the second one will start <tr id="XXXXXPanel". Comment out both of these and the section will disappear.
