How to add "Linked Documents" of type "Address"

Hi all,

I am trying to add a “Linked Document” of type Address in my own DocType. I tried it like this:

However, when I open the document, I get the error:

pymysql.err.OperationalError: (1054, "Unknown column 'tabAddress.links' in 'where clause'")

Could someone please point out, how I would set the Link Fieldname in my Doctype to show the linked Addresses in the top section of my documents?

Thanks!
