I have two objects: House and Owner
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?
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”)
Master Detail relationships only link to the ID field of the parent record — you can’t change this. That said, the UI uses the names for the convenience of users which is why you’re not able to search via ID there.
