Salesforce Master-Detail Relationship

Question

2

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")

Answer 1

You can't modify the Master Detail relationship's link to the parent record's ID field. However, the UI relies on names for user convenience, which is why you won't be able to search by ID there.

Hope this helps!
