Link to Form in Context

[Jesse]

Hey guys,

I’d like to make an action button that links to a form view in a related record but I’d like to prefill the ref column in the form…
Just like the “new” button in a ‘related column’ (ref rows) prefills the ref column in the form view.

I started with LINKTOVIEW(My Form View), which works fine, but have no idea how to prefill the ref column from there.

Guidance appreciated.
