XML Code That Defines a Many-To-Many Relationship

You must define the Microsoft Outlook folder that stores these objects. However, for this example, it is not desirable to display these objects to the user. Therefore, you use a hidden folder in Microsoft Outlook that you define in the code as the following:

predefined_folder="1"

Because a form is not required to display these objects, you do not define a form. You add the following code to the siebel_basic_mapping.xml file:

<type id="Opportunity.Channel_Partner.Association" hidden_folder="true" folder_type="10" display_name="OCHP">

<form message_class="IPM.Contact.SBL.OpportunityChannel_PartnerAssociation" display_name="OpportunityChannel_PartnerAssociation" icon="type_image:Generic:16"></form>

<field id="OpportunityId">
