title: Salesforce Master-Detail Relationship
body: <p>I have two objects: <strong>House</strong> and <strong>Owner</strong></p>
  
  <p>Owner has a field "ID", House has a field "Owner_ID", how do I link "Owner_ID" to the "ID" field in Owner using a Master-Detail relationship in the Salesforce under schema builder?</p>
  
  <p>When I create a new M-D relationship in House, It doesn't have a selection box to let me set which field does a M-D relationship refer to in Owner. It defaulted to the "Owner Name" field. (ie. when I insert a new House, I can search for the owner by "Owner Name", but cannot search for the owner by "ID")</p>
